1 Executive Summary The following Lighting Existing Conditions and Design Criteria Report examines and summarizes the existing lighting systems considered for redesign in Broadway Plaza. These spaces include the apartment lobby, skyway, function room, conference room, pool, and groundlevel facade/roof exterior. All information pertaining to the existing lighting layout, hardware, and light loss factors has been indicated. Additionally, other factors affecting the lighting design, including architectural materials and reflectances, are considered. Properties affecting daylight within the space such as glass type, transmittance, and window location must also be considered for lighting designs that are functional during both the day and evening hours. The first step to successful lighting design embarks on the establishment of design criteria to provide a functional and desirable atmosphere. Appropriate design criteria pertaining to the redesign spaces were initially established based on suggestions made by the IESNA Handbook and special considerations within the space. An all-encompassing design goal to create a luxurious and artistic beacon among the downtown district is to be considered during all stages of redesign. Designed to attract new workers and residents into the city, Broadway Plaza must highlight its modern and functional appeal and set itself apartment from other luxury apartment complexes. After a thorough analysis of all redesign spaces using high-tech lighting computer software and actual available photographs of the system in use, it was determined that while Broadway Plaza meets many of the goals set forth, improvement is still very possible. Some of these areas of improvement include, but are not limited to, spatial perception, creation of points of interest, avoidance of direct and reflected glare, light distribution, and accentuation of surface characteristics. Spaces such as that of the conference room and lobby should strive to improve their luxurious appearance, while safety concerns prove more prevalent in the pool area. However, if any factor should be considered within all the spaces, it is that of daylight integration and control. Daylighting control is not accounted for in almost all areas of the building, creating the possibility for the misuse of a potentially valuable resource. As a whole, redesign should be contingent with improvement of Broadway Plaza s aesthetic appearance, safety conditions, comfort, and the idea of the building as an artistic statement. Coinciding with IESNA suggestions for design criteria, power density limitations and control system requirements under ASHRAE 90.1 were also evaluated. Initial studies conducted on the lighting design by Burt Hill (prior to finalized construction documents) perceived an overall compliance of power density by more than 2% for the building when treated as a whole rather than through the space-by-space method. This value may have become inaccurate after the construction documents were completed. However, the building as a whole may meet ASHRAE regulations while not complying with a space-by-space evaluation. In either case, those spaces not meeting ASHRAE 90.1 power density requirements including the skyway, function room, conference room, and exterior require improvement for compliance with the standard. Control requirements for the conference room must also be revised for ASHRAE approval. During redesign, all spaces must take power density and control requirements into consideration to either maintain or improve upon the current conditions.

2 General Building Overview Lighting Design Lighting in Broadway Plaza is predominantly fluorescent with low voltage track for accent of entrances and primary walls. The system is run off of 277V for retail and multifunction spaces on the lower floors while residential lighting on the upper floors is run from 120V. Among the spaces not analyzed, the basement parking is dominated by metal halide surface ceiling-mounted fixtures both in the parking area and along the ramp and loading dock regions. The unoccupied retail spaces are currently lit by simple fluorescent strip fixtures for functionality rather than aesthetics. Room has been left on the panelboards for new lighting to be determined upon the move-in of a retail agent. The typical residential unit takes advantage of low energy fluorescent lighting in several spaces. Lensed compact fluorescent downlights line the corridors. The kitchen features a fluorescent wraparound and undercabinet fixtures. A pendant is hung in the dining room while decorative close-to-ceiling halogen fixtures are utilized in the bedrooms. General Design Goal Broadway Plaza looks to market itself as a unique home away from home for business travelers and long-term visitors to the city. To accomplish the goal of attracting high-end cliental, Broadway Plaza must make a statement among the surrounding cityscape. Creation of a prestigious artistic lighting scheme that highlights the unique amenities and architectural features of the building may do just that. Currently, Broadway Plaza uses many quality lighting aspects, but does not draw the attention it deserves. Thus, the lighting design must be appealing and welcoming as a home- with an artistic flare. Control Devices Broadway Plaza possesses the capability to control various lighting applications through a building automation system. Exterior and interior alike are connected to a lighting system control panel in the building automation system. This panel controls automatic shutoff during vacancy of a space as well as monitors power consumption. Timer schedules and photocells also work towards this same goal of energy conservation. Likewise, several areas possess the ability to be dimmed when lower lighting levels are desirable or an abundance of daylight is available. Through these systems, Broadway Plaza may conserve energy for the environment and its electricity bill. Power Density In February of 2002, Burt Hill conducted a power density lighting compliance study according to the Minnesota Commercial Code. Using the space-by-space method of power density calculation and estimated loads, Broadway Plaza is permitted W according to ASHRAE In accordance with standards, Broadway Plaza is calculated to consume W, a compliance of over 1201W. At this point, the lighting passed compliance at a design 2% better than code. However, as one can see in this report, several areas, after final construction document phases, do not meet the space-by-space requirements. Therefore, though the building as a whole may have met ASHRAE 90.1, on a space-by-space basis, several of the rooms evaluated do not.

3 Apartment Lobby Existing Lighting Overview The current lobby lighting scheme utilizes a variety of lighting resources to create a diverse atmosphere within a single space. As one enters, he notices the first of many popular cove areas within Broadway Plaza that light the space primarily through indirect light. Architectural accent lighting is provided along the far wall and reception area. A recessed ceiling alcove covered by diffuse glass highlights the decorative wall. This diffuse ceiling allows for illumination from above in addition to spotlighting by MR16 wallwashers from the front. The reception, meanwhile, stands apart through the use of a suspended box illuminated from above by recessed fixtures. To facilitate passage into the interior, MR16 fixtures along curved tracks lead the visitor into the core elevator lobby. Simple fluorescent lensed downlights, meanwhile, provide direct illumination for reading and other tasks to take place in the lounge area. Bringing all of these systems together, a Lutron graphik eye dimming system allows for various moods and settings depending on the activity or time of day. While the electric lighting system is stringently planned out, the space does not seem to take into consideration the vast amounts of daylight brought into the room through the South-facing windowed facade.

6 Apartment Lobby Continued Control Devices A sixteen zone Lutron Graphik Eye Multi-Scene Controller controls general lobby lighting. Two dimming panels at 277V and one panel at 120V are provided for this purpose. Although the controller may accept up to sixteen zones, only ten zones are currently being utilized. These include two for downlighting of the lounge, two for track fixtures, three for coves, reception area, entry wallwashers, mr16 spotlights, and luminous glass accent. One dimming panel control as required for 2,500 sq.ft. under ASHRAE 90.1 is provided near the reception area. A lighting control system panel, a component of the building automation system, further controls this graphik eye. Automatic shutoff is provided for all lobby fixtures not located on emergency circuits through this system as required by ASHRAE Necessary egress lighting will remain on for safe transition during an emergency. Manual override of the automatic shutoff is also possible for up to four hours as again required by the standard. Integral switching is provided on the reception task lights as per ASHRAE 90.1 as well. Daylighting Elements The entire South-facing front facade is flanked by 13 high bays of Low-E insulating glass (see architectural surfaces) that run from nearly ceiling to floor. The West facade along the lounge area and connection to the skyway lobby also contain this window configuration. No daylight control or integration is provided for under the building contract. Daylight may significantly contribute to the space, and may allow for lower energy consumption during the daylight hours. Design Criteria and Goals Appearance of Space and Luminaires (Very Important) As the most prominent space that high-end clients will see, besides the individual apartments of course, the look of the lobby is extremely important. Concentration should focus on the selection of appealing luminaries as well as on the creation of a sophisticated and welcoming atmosphere. The lobby should look luxurious and psychologically draw possible cliental to desire residence in Broadway Plaza. The lavish finishes within the lobby should be highlighted while the atmosphere shall remain calm. This is currently done through the use of a diffuse panel illuminating a bronzed wall, a glowing artistic beacon above the reception, and indirect lighting provided by built-in cove applications. However, the lounge area does not presently take advantage of any artistic expression lighting. This issue should be addressed in any redesign. Meanwhile, circulation lighting from curved track fixtures along a lowered corridor ceiling guides visitors to the building s core elevator lobby. Visitors should enter the lobby with feelings of awe, comfort, and pampering provided by the lighting system while also being safely guided to their destination.

7 Apartment Lobby Continued Color Appearance (and Color Contrast) (Important) With the illustrious finishes in place, the color appearance of the various portions of the lobby should be considered. Wood and stone, alike, should be lit with lamps that bring attention to the tiniest details of the material and never appear to wash out the surface. The use of the Munsell color system may provide insight into the best choice of lamp for each application. Enough contrast to catch the eye yet not overwhelm should be provided. While currently lit by only white light, the addition of colored lamps for accent and for creating an artistic focal point for passerbies along the street is not out of the question. Daylighting Integration and Control (Important) The large curtain wall and massive amounts of glass surrounding the lobby can cause both visual and thermal discomfort. The entire front entrance of the lobby faces South, making thermal heat gain and direct sunlight in the eyes of primary concern. While surrounding buildings may work to block out some of the direct sunlight, their height and distance from the structure will potentially still allow direct sun to enter. Therefore, a daylight study, taking into account these structures, should be preformed to pinpoint problems or discover possible opportunities for energy savings. All of the window surfaces used take into account solar transmission and are low-e type glass assemblies. Effectively utilizing the large amount of daylight available should be in the forefront of design thought. Additionally, a smooth transition between exterior to interior light levels should be considered and designed for. The lobby provides a transition space between the outdoors and interior space, and therefore, must promote a sense of security and welcome while allowing for adaptation between illuminance levels. Direct Glare (Important) The lobby should provide a space that is comfortable for the various tasks that may take place within it. Whether occupants are reading, waiting, relaxing, or passing through, direct glare from overly luminous surfaces and/or luminaries should be avoided at all costs. As the space itself is considered first class, it is important to keep the occupants from feeling like secondhand afterthoughts. Light Distribution on Surfaces (Important) Distribution of light on varying surfaces is a means to garner attention, guide, and provide a relaxed atmosphere. While the light distribution should not be even over all elements in the space, a hierarchy of luminance should be developed to create an atmosphere of relaxation. This hierarchy should take into account paths of travel and necessary tasks within the space, as well as provide focal attention. These ideas will be addressed in the recommendations section at the end of this report. Luminances of Room Surfaces (Important) The luminance values of room surfaces are important within the lobby space for both spatial perception and comfort. Brighter surfaces come forward while darker surfaces recede. In order to create the depth desired, luminance ratios on various walls must be adjusted accordingly. Likewise, the eye-catching nature of bright luminance surfaces acts as a means of drawing attention and guiding visitors. Objects that are lit to the correct luminances in the background can draw occupants towards them. Additionally, luminances of surfaces must be in correct

8 Apartment Lobby Continued proportion to avoid uncomfortable eye adjustments. In the lounge area, where reading tasks will take place, the luminance ratio between task and far surroundings must comply with a 1:10 or 10:1 ratio as recommended by the IESNA. Likewise, a 1:3 or 3:1 task to adjacent surroundings ratio is advised. Modeling of Faces or Objects (Important) Modeling of the faces of those moving in and out of the space is not of primary concern due the short nature of time generally spent within the lobby. However, it is desirable for all faces to be distinguishable and uniformly lit to avoid shadows. Meanwhile, the receptionist s face should be easily distinguishable with a high level of vertical illuminance that is uniform over her entire face. The lighting should create no unflattering shadows nor should features that may be unbecoming be accented. Points of Interest (Important) Coinciding with the idea of spatial appearance, it is important to create focal points to attract interest within the space and distinguish it from other apartment lobbies. Broadway Plaza currently contains no strong points of interest within the lobby besides the accented bronze wall and reception desk. These, meanwhile, are large in nature and do not provide an artistic focal point. Therefore, it may be desirable to have the lighting design itself create a focal point within the space or add artwork with integrated accent lighting to the area. Reflected Glare (Very Important) The issue of reflected glare is of especial importance considering the materials used to furnish the lobby. All wood, stone, and tile finishes are specular in nature and create mirror-like reflections from direct light striking them. Direct light on these materials should be kept to a minimum and all cut off angles should be considered for reflected light back into the eyes of the occupant. Reading tasks within the lounge as well as simple waiting activities may be hindered by reflected glare on the task plane. Uneasiness due to this glare should be avoided at all costs to provide a comfortable atmosphere for the occupant. Source/Task/Eye Geometry A lobby is not a task intensive space by any means. However, enough illuminance should be provided on the receptionist s desk to aid in her daily tasks and prevent eyestrain. Additionally, if the receptionist is to use a VDT in her daily work, avoidance of direct and reflected glare in the monitor as well as compliance with recommended luminance ratios of 1:3 or 1:10 should be achieved. A lower overall level of illuminance with a system of local task lighting (as currently used) is advised for receptionist activities. Surface Characteristics (Important) Once again, the lighting design should accentuate each material s rich texture. This can be accomplished through the use of color and angle. Characteristics such as specularity, color variation, contrast, and texture should all be considered. System Control and Flexibility (Important) As the space will appear very differently during the day and evening hours, it is important to maintain a means to control the various lighting applications. A dimmable lighting control sequence such as the current graphik eye system should be maintained to illuminate the lounge, entrance, and reception area independently of one another. Moods may then be created based on the time-of-day, season, or occasion.

9 Apartment Lobby Continued Illuminance (Horizontal) Suggested horizontal illuminance is 10 fc along the general entrance area of the lobby. The lighting should be driven to meet this value. However, as few intensive tasks will take place in the space, this value is only somewhat important and may fall below to create an even more relaxed atmosphere or during the late evening hours. Levels should not be dimmed to extremely low values during the day to provide adequate light for exterior to interior adaptation. Additionally, daylight levels, may at times, provide almost all the necessary illuminance to maintain general illuminance levels, and should be considered in the design. In the lounge area where causal reading tasks may take place, illuminance levels along the work plane should reach a desirable 30fc. In the receptionist area, this value should be increased to 50 fc on the desk surface to accommodate all tasks. As movement spaces, corridors shall have a horizontal illuminance of 5 fc uniform over the floor surface. Illuminance (Vertical) A uniform illuminance level of 10 fc is recommended for the receptionist s facial features. All areas of the lobby should also strive to meet this value with no levels falling below 5 fc on faces, either sitting or standing. Vertical illuminance on points of interests such as the bronzed wall should reach 50 fc or 30fc depending on the application.

13 Apartment Lobby Continued Critique of Existing Conditions While many areas of the lobby satisfy the design criteria established, other goals fall short when analyzed. The lounge area is one such zone. While the vertical facial illuminance is greater than the minimum 3 fc, the work plane illuminance falls short of the 30 fc goal. Through the contour image, we can see that almost no areas within the lounge reach this value. With very little light reaching the task, reading within this space will be difficult. Likewise, the large gradient over the space can cause problems, as differences between areas in shadow and light may cause distractions. This may be especially true during the daytime hours when additional illuminance will be added to the front of the space by daylight. The entrance area, meanwhile, provides glare free uniform illuminance for tasks and facial rendering through indirect lighting applications. The accent wall is highlighted by a greater illuminance, but once again, its uniformity does not fully bring out the essence of the artwork from ceiling to floor. The reception area does a more than adequate job in preventing glare through the use of the diffuse accent behind the VDT monitor. Meanwhile, uniform vertical illuminance for facial rendering is established. The task lighting provided for the reception desk supplies enough illuminance to the work plane for intensive paper tasks. Photographs, meanwhile, display the problem with daylighting control and glare. Direct daylight is capable of entering the lounge space and thus, causing direct glare in eyes or on tasks. While glare is not created by the lighting system itself, daylight striking the front entry floor tiles can reflect into the eyes of those exiting. Likewise, while the indirect system does not cause distracting luminance ratios over most of the ceiling, the highly luminous coves may prove to be glare sources for the receptionist working at the desk. The space matches its design goals in terms of power density and flexibility. Complying with ASHRAE 90.1 power density and control requirements, the lobby lighting provides the ability to turn fixtures on or off and to dim a variety of zones. With this ability, the space creates the distinguished and lavish appeal that it desires. However, accentuating the surface characteristics would strengthen this mood and the appeal of the expensive finishes. This design initiative is the ultimate goal upon which the lobby should improve upon. The ability to bring out the rich color and texture of materials should be established, providing a grand and first-class appeal.

14 Skyway Existing Lighting Overview The skyway features general illumination provided by a combination of open downlights and linear fluorescent pendants in 16 sections between downlighting applications. Curvable cove fixtures and compact fluorescent wall washes highlight the entrances to the skyway. The elevator lobby is lit by open downlights while two retail display cases are lit from above by two linear fluorescent strip fixtures each.

A ceiling-mounted daylight sensor is located along the rear wall near the display case in the West corner. Through this control device, the lighting system is lowered and increased depending on the daylight available. In case of failure, the system provides a bypass switch to enable lighting to be turned on if the sensor fails. Furthermore, four ceiling-mounted ultrasonic occupancy sensors line the space. This amount is more than the necessary one as required by ASHRAE Occupancy sensors are capable of turning off the lighting within 30 minutes of an occupant leaving the space. Together with the daylight sensor, these devices are connected to the lighting control system and subsequent building automation system. This provides automatic shut off control of the space as required by ASHRAE Manual override of the automatic shutoff is also possible for up to four hours as again required by the standard. A timer switch is also provided for the space, but is currently not in use. Daylighting Elements The entire length of the skyway is covered on the South and West facades with 9-6 high bays of Low-E insulating glass (see architectural surfaces) that run from nearly ceiling to floor. Daylighting control is provided by a daylight sensor near the rear wall above the display case and is connected to the lighting control system. When sufficient amounts of daylight are present, the lighting in the skyway will be switched off based on location. Design Criteria and Goals Appearance of Space and Luminaires (Important) The skyway is the most public area of the building and must strive to make passage through the building a pleasant and safe experience. The public should feel secure and comfortable while either passing through or visiting the future retail locations along the way. Light levels should Total LLF

18 Skyway Continued be low enough to provide comfort, yet high enough to promote safety. While the fixtures should coincide with the lavish appeal of Broadway Plaza, it is important to remember that their placement is open to public interference and vandalism. Thus, fixtures should be chosen for aesthetics, efficiency, and suitability to the public atmosphere. Color Appearance (and Color Contrast) (Very Important) Color appearance is especially important in regards to the display lighting along the skyway. Although all lamps used in the skyway should have a CRI above 70, the overall color of the skyway is not as crucial due to the nature of time spent in the space. It may be indeed desirable to use colored lamps as general illumination to create a more lively and inviting atmosphere. Retailers, meanwhile, are concerned with the appearance of their products in the display windows. If a high color rendering and natural appealing appearance is not maintained over the merchandise, sales figures from window shoppers will plummet. Therefore, color and contrast of these points of interests must appear attractive and psychologically appealing to consumers. CRI must be above 80 and possibly reach 90. Daylighting Integration and Control (Important) As windows flank the entire South and West facades of the skyway, daylighting integration and control should be taken into consideration. Daylight is desirable to create a natural and comfortable feel for the retail atmosphere. However, direct penetration of the sun may cause an annoyance to pedestrians as well as a nuisance to the retail lighting display windows. Direct Glare (Important) Direct glare poses the largest dilemma in terms of daylight control. Direct sunlight may easily enter the skyway and provide a glare source to pedestrians passing through the space. This is not only uncomfortable, but detracts from the psychological calling of the retail windows to impulse buy. Direct glare is not as important in terms of the luminaires due once again to the nature of mere passage through the space. Luminances of Room Surfaces (Important) The luminances of room surfaces can be a means of way finding and directing pedestrians in their travels. Brighter surfaces seem to come forward and draw attention. Creating areas of varying luminance should minimize the tunnel effect associated with long corridors. Modeling of Faces or Objects (Important) Once again, faces and objects located within the display windows should possess uniform and attractive illumination to promote their marketability. Objects should not possess undesirable shadows due to the angle of the light. Additionally, every effort should be put forth to model faces within the skyway space itself. For security and safety purposes, adequate levels of vertical illuminance should make clear facial rendering possible. Shadows (Very Important) No shadows should be present within the skyway area. Shadowing creates an unsafe psychological feeling in what should be a secure public transportation space. This is especially important in terms of facial shadowing that can make other pedestrians appear threatening.

19 Skyway Continued Points of Interest and Sparkle/Desirable Reflected Highlights (Very Important) The retail display areas should be accented to sell merchandise and create a desire to impulsively buy an item. Jewelry and other precious objects that may be displayed within the window should create the sparkle that makes them valuable purchases. This may be done through individual fixtures aimed at specific features of the display rather than an even overall illuminance. Additionally, the general skyway lighting should call attention to circulation modes such as the elevator, stairs, and skybridge as a means of way finding. Reflected Glare (Important) The combination of glass specularity and improperly placed luminaires can cause reflected glare and obscure merchandise. Reflected glare from luminaires in the display windows may cause a dilemma during the nighttime hours. During this time, the luminance seen from the nearby exterior is low, making reflections in the glass possible. This, however, should not pose a major problem during normal daytime conditions. Additionally, during the night, surfaces within the display should be kept bright to minimize reflections of visitors in the glass. Therefore, day versus night conditions in the display cases should be considered when lighting the space. Reflected glare off of wall and floor surfaces should not pose a large problem in the general skyway area due to the unpolished nature of the stonework. System Control and Flexibility The system should strive to integrate light levels based on the time-of-day and daylight available. During the nighttime hours, higher levels of illuminance are desirable to maintain the feeling of security. During the daylight hours, meanwhile, the system should provide for lower and varying illuminance levels based on the amount of daylight entering the space. Illuminance (Horizontal) Horizontal illuminance levels should be maintained at 5 fc for simple orientation and short visits. The illuminance level in the display case should, meanwhile, reach levels near 100 fc to fully illuminate the contents. Illuminance (Vertical) Vertical illuminance for facial rendering should be kept uniform at a minimum 3 fc throughout the skyway. Avoidance of facial shadows and ominous appearances is a must. Vertical illuminances within the display cases should fall around 50 fc and avoid undesirable shadowing effects.

With varying fixtures and applications, the atmosphere is comfortable and luxurious looking. The accent wall is clearly accentuated to provide a focal point upon entering the space, while the cove application at the elevator lobby accentuates architectural detail without compromising the eyes to glare. Luminance ratios between the floor and the ceiling are not of concern for simple walking tasks. Illuminance values along the elevator lobby floor,

23 Skyway Continued skyway floor, and vertical facial plane are for the most part large and uniform. The space maintains its sense of security by ease of facial recognition and the absence of shadows. However, merchandising within the retail display cases may be compromised by the glare of daylight as well as the lower vertical illuminances seen within the space. While consuming an astronomical amount of power, the vertical illuminance at any point within the display is not at the recommended 100 fc level. Jewelry and other precious objects within the displays will also not possess the sparkle and detail that would be present with a less diffuse lighting source. According to ASHRAE 90.1, the total allowable power density for a corridor area is 0.7W/sq.ft. The current system installed in the skyway far exceeds this permissible value. Likewise, the value acceptable for display case lighting is also surpassed. During the nighttime hours, when lighting levels will be at the highest output, power density will surely be surpassed. Thus, the space must be redesigned to satisfy power density requirements set forth by ASHRAE. The skyway does indeed take into account energy conservation through several occupancy sensors as well as a daylight sensor. However, the means to which this daylight sensor works is unknown. Specified as a dimmable application, no ballasts provided for the skyway luminaires allow for dimming. Therefore, actual application of this daylight system to the skyway is unknown.

24 Function Room Existing Lighting Overview The function room takes advantage of the Lutron graphik eye dimming system. Dimming zones cover areas from the curved mr16 track along the sidewalls, to a wall washed central wall, to the curvable cove fixtures. Through this dimming system, a variety of atmospheres are possible with the cove lighting, downlights, and track fixtures present. Wall sconces add accent light to the entryways and to the far wall as well. Fig. 5: Function Room Floor Plan With Dimensioning Total Area: 1608 sq.ft.

Zones currently occupied include two for track fixtures, downlighting, sconces, coves, and wallwashers. Two dimming switch-stations control the system, more than required under ASHRAE Once again, the graphik eye system is operated under the lighting control system panel and building automation system. Automatic shutoff is provided for all fixtures through this system as required by ASHRAE Manual override of the automatic shutoff is also possible for up to four hours as required again by the standard.

27 Function Room Continued Daylighting Elements The function room contains three sets of South-facing windows. The two groups on the ends consist of two windows at 8 high. The center group is actually a continuation of the curtain wall system from below, also at 8 high. All glass is Low-E insulating (see architectural surfaces.) No daylight control in the form of blinds, etc. is provided for under the building contract. Design Criteria and Goals Appearance of Space and Luminaires (Important) The lighting of the function room should relate to the overall design theme of comfort and luxury within Broadway Plaza. Any visible fixtures should be high quality in efficiency as well as appearance. Architectural features should be highlighted while creating a welcoming and comfortable atmosphere to gather in. The appearance should compliment that of the lobby. This can be especially difficult considering the largely dark surfaces throughout the room. Color Appearance (and Color Contrast) (Important) As the finishes used within the space are strong in nature, the surfaces tend to be more stimulating. Thus, it is important that the color appearance of the lamps work to maintain this stimulation. Lamp sources should be evaluated against these surfaces to accentuate the intense green and blue colors. Daylighting Integration and Control (Somewhat Important) Although the space does not possess the largely proportional glass facade that many other spaces do, daylighting should not be altogether forgotten. It is important to control direct light and unwanted glare from daylight that may interfere with the comfort of the occupants of the space. Direct Glare and Reflected Glare (Important) The function room should provide a space that is comfortable for the various tasks that may take place within the space. Whether occupants are reading, playing card games, relaxing, dancing, or dining, direct and reflected glare from overly luminous surfaces and/or luminaires should be avoided at all costs. This space looks to attract high-end public gathering events as well as to provide a relaxing space for residents to use during the day. The space can therefore, clearly possess no direct glare that blinds occupants and distracts tasks and/or public meetings. Light Distribution on Surfaces (Important) As most areas of the function room strive to be of equal importance, it is important to provide enough peripheral light distribution to give the feeling of a much larger space. Light distribution should fall from the ceiling to the floor and avoid unwanted shadowing near the floor edges. By illuminating selected surfaces with an ambient light, the space will appear more relaxed, comfortable, and larger. Light Distribution on Task Plane (Uniformity) (Important) No matter the event to take place within the function room, uniformity and control of the task plane is important. Those sitting in the wings of the room should have the same amount of

28 Function Room Continued illuminance to read as do those sitting in the center. A range of activities could take place in any portion of the function room, and thus, enough task illuminance must be provided at all points within the room. Luminances of Room Surfaces (Important) Spatial perception and comfort call for the function room to vary the luminance values to achieve the desired atmosphere for each individual event. As the room strives to function as a large gathering space, it is important to provide more ambient light and perimeter illuminance to increase the perception of size. In order to create the depth desired, luminance ratios on various walls must be adjusted accordingly. The primary center wall, meanwhile, is thought of as the prominent focal point of the space. Thus, is it important to take this into account and increase its luminance. Additionally, luminances of surfaces must be in correct proportion to avoid uncomfortable eye adjustments. In a room where reading tasks will most likely take place, the luminance ratio between task and far surroundings must comply with 1:10 or 10:1 ratio as recommended by the IESNA. Likewise, a 1:3 or 3:1 task to adjacent surroundings ratio is advised. Modeling of Faces or Objects (Important) As the public gathering space of the building, visitors to the function room should be lit to ensure a pleasant appearance at all gatherings. Facial rendering should be maintained and unwanted shadows or highlighting of unappealing facial features should be avoided. System Control and Flexibility (Very Important) This room may be used for a variety of purposes from meetings to exhibits to dinners and dancing. Thus, it is important to also provide a variety of lighting levels and effects. Dimmable systems, like the current graphik eye, should be provided and control easily maintained by those using the space. Illuminance (Horizontal) It is recommended to provide 30 fc on the horizontal work plane for casual gathering and common tasks. The control of this illuminance level is more important. A range of 5 fc to 30 fc is desirable for the activities to take place within the function room. Illuminance (Vertical) Vertical illuminance of faces within the space should be at a uniform 10 fc or greater during meetings and 5 fc during casual activities.

31 Function Room Continued Previous Page: Center Cove Ceiling Above: Function Room Work Plane Critique of Existing Conditions The lighting system of the function room seems to provide a funneling affect of attention. While this may be desirable for receptions when distinguished guests will be centered along the front wall, it is not desirable for a casual atmosphere. The graphik eye system may be able to aid in increasing uniformity of the illuminance, but will not be able to bump up the inadequate task light along the wings of the rooms. In these areas, illuminance is too low for reading and/or card playing at 25 fc during the evening hours. In terms of vertical facial rendering, the space matches or exceeds expectations of uniformity and illuminance values, no matter whether guests are seated or standing. Luminance ratios within the space, however, may pose a problem. Ratios between the luminance of the cove ceiling to the darker surrounding walls or task plane are greater than 14, thus, not reaching design goals. This can pose a problem and glare may result in the eyes of those trying to relax, dine, or work within the space. The overall symmetrical feel of the room also compromises spatial perception of the space. According to Flynn modes, a more relaxed atmosphere may be achieved with the addition of varying luminance values along the walls. While the walls do indeed possess luminance, the combination of intense indirect light contributed from the center cove as well as the symmetry of wall luminance (as opposed to the asymmetrical Flynn mode proposition) does not create the

32 Function Room Continued degree of relaxation desired. However, if wall luminance were to be varied, creating points of focal interest, while the intensity of the indirect light is also decreased, the space may become much more relaxed. Coinciding with the dark surroundings, increased power consumption is required by this system. The power density exceeds the 1.4W/sq.ft. allowable by ASHRAE Therefore, not only should the system work to increase illuminance values and decrease luminance ratios, it should seek to do so through the use of even less power.

33 Conference Room Existing Lighting Overview Indirect lighting is the primary lighting method for the conference room. Two linear fluorescent pendants above the table indirectly light the ceiling while releasing a soft ambient light through the lower metal diffuser. Recessed compact fluorescent wall washers wash the end walls for accent and spatial perception increases.

While one switch each controls the wallwashers along the perimeter, another switch operates the pendant fixtures. This is more than compliant with the requirement of one control device for this area by ASHRAE However, the conference room is not directly connected to the lighting control system and therefore, not compliant with automatic shutoff requirements as found in ASHRAE Without automatic control, energy may be lost if lights are accidentally left on during unoccupied times. Daylighting Elements Once again Low-E insulating glass (see architectural surfaces) is used to provide daylight to the conference room. Three windows at 8 high make up the entire West facade, barring the necessity of the column line in this location. No daylight control in the form of blinds, etc. is provided for under the building contract. Design Criteria and Goals Appearance of Space and Luminaires (Very Important) Along with the flexibility of the controls and minimization of glare, the appearance of the space should be the ultimate focus of the room. Similar to the lobby, the conference room is the most prominent space for Broadway Plaza s overall expression to high-end cliental. Therefore, fixture selection for aesthetics and the quality of the light is extremely important. Business travelers frequently using the space for meetings should be both impressed and comfortable. A distinguished comfortable psychological atmosphere is a must to further Broadway Plaza s place as a business haven.

35 Conference Room Continued Color Appearance (and Color Contrast) (Important) Poor coloring rendering is not acceptable when trying to sell a presentation and conduct million dollar business ventures. A CRI of 80 is required for all lamps. Presentation images, furnishing and especially skin tone should all possess good coloring rendering for a natural and desirable appearance. Daylighting Integration and Control (Important) While it is not essential to integrate daylight into the space, daylighting aspects can create a more relaxed atmosphere and provide relaxation through a view of the outdoors. The Westfacing windows allow for daylight to enter the space, but special provisions should be taken to control and eliminate this daylight for presentation and work purposes. Control of the glass window wall facing the reception should also be provided for privacy and presentations. No such control of window openings was furnished under the building contract. Direct Glare (Very Important) Clearly, with the use of VDT and presentation boards in the conference room, direct glare in monitors or in specular posters should be avoided. Direct glare or hot spots on items is both distracting and uncomfortable in a working atmosphere. Occupants should never be looking directly into a luminaire or experiencing any discomfort. Light Distribution on Surfaces (Important) Accent should be placed both on the luxurious furnishings in the room as well as on any specific points of interests that may be located here. Points of interest highlighted by light should be created to provide variety in the space. Light Distribution on Task Plane (Uniformity) (Important) As the conference table can accommodate several occupants, it is important that light levels along the entire table be maintained at a high illuminance level for all tasks to be preformed. The specularity of the table may also cause hot spots and unwanted glare, both of which should be avoided. Luminances of Room Surfaces (Very Important) Luminance ratios are very important in this space due to the facial rendering of occupants. Luminance ratios between VDT and adjacent surfaces should not exceed 1:3 or 3:1. This is especially hard to accomplish if black computer backgrounds are to be used. Meanwhile, luminance ratios between the VDT monitor and far surroundings, including the luminous ceiling, should not exceed 1:10 or 10:1. Additionally, various presentations along wall surfaces may take place within the space. Lighting for presentation boards positioned along walls should be provided. Meanwhile, control should also be considered for possible projection presentations to take place along these same walls. Similarly, luminance levels should be used to create a psychological spatial relationship. Currently, the wall washed end walls elongate the space. Due to the small nature of the space, it is desirable to not only psychologically lengthen the space, but also increase all dimensions, creating a relatively larger appearance.

36 Conference Room Continued Modeling of Faces or Objects (Very Important) Facial features should be uniformly lit with illuminance levels that avoid unattractive shadows or extreme brightness. Facial expressions should be clearly distinguishable. The lighting should create no unflattering shadows nor should features that may be unbecoming be accented Reflected Glare (Important) As VDT monitors will be used in the space, reflected glare on screens should be avoided at all costs. Unwanted glare may cause eyestrain and discomfort, making it hard to work for long periods of time. Luminaire cut-off angles should be located out of the offending zone of the computer while indirect lighting luminance ratios should be minimized to avoid reflected glare from ceiling surfaces. Additionally, glass surfaces should be evaluated for reflected glare into the eyes of the occupant or onto the computer screen. Source/Task/Eye Geometry (Important) Once again, as with the VDT screen, adequate illumination levels to complete tasks should be provided. Luminaires and highly luminous surfaces should be located to avoid direct or reflected glare on the task. System Control and Flexibility (Very Important) As a variety of presentations and work atmospheres are desirable within the space, it is important to take into consideration illuminance values and the location of the light to create that desired atmosphere. Thus, the system must provide different lighting scenes, as it currently does, to meet the desired high or low illuminance for business related ventures. Adaptation to the needs of the client is a must. Illuminance (Horizontal): Horizontal illuminance levels on the conference table should reach 30 fc or more for business meetings. For presentation purposes, the system should reduce light levels to various degrees from 3 fc to the maximum level. Illuminance (Vertical): Although it is not important to maintain high vertical illuminances on all surfaces, faces should be uniformly lit to a value of 10 fc for facial rendering. Higher vertical illuminances along the periphery may also be desirable to create a more relaxed atmosphere for working. VDT screens should also possess 10 fc or more of vertical illuminance.

39 Conference Room Continued Critique of Existing Conditions As this space is to be the professional focus for an apartment complex striving to attract high-end business travelers, the conference room should accentuate the spare-no-expense for the customer attitude of Broadway Plaza. However, the luminaires chosen for the space do not coincide with these goals. The pendant fixture does not appear to be as lavish as one would expect, especially considering its use in the skyway as well. Additionally, while the walls are accented to provide the desired elongation to the space, their gradient and inability to create focal attention leave the space feeling drab. As the finishes used within the space are by no means as extravagant as those used in other areas of the building, it is important that the lighting design work that much harder to compensate in quality. In terms of illuminance, the system performs well for direct light falling onto the task plane, but falls short of goals in terms of luminance ratios. Illuminance for facial rendering is more than adequate and uniform throughout. No harsh shadows can be seen on the face at any point along the table due to the symmetrical nature of the lighting system. Additionally, an above requirement of 50 fc is distributed fairly evenly over the entire conference table. The indirect system also poses no problem in terms of direct glare. The fixture and luminous ceiling are out of view of the VDT screen and thus, no direct light should fall upon it. This out-of-view and close proximity condition also helps to negate the concern of luminance ratios. Although the 1:10 ratio between the VDT monitor and ceiling is exceeded, the ceiling is so close to the desk that is may be thought of to fall within the 1:3 ratio requirement for close surroundings. Thus, the ratio should not be considered a hindrance. Compliance with ASHRAE 90.1 is also not satisfied in terms of both power density and control systems. While three switches are provided to create the necessary scenarios for presentation purposes, they do not satisfy automatic shutoff control. During periods when the room is inactive, valuable power may be uselessly consumed. It is this same power density of 1.67W/sq.ft. that exceeds ASHRAE s limitations of 1.5 W/sq.ft. Thus, the conference room must strive to lower power consumption, increase focal attention, and decrease luminance ratios to ensure a comfortable and attractive working atmosphere.

40 Pool Existing Lighting Overview Along with the skylight elements above the pool areas, luminaires located above each of the individual pools illuminates the water primarily through indirect light. These indirect fixtures wash ceiling alcoves above the small wading pool and jacuzzi. Above the lap pool, the indirect fixtures illuminate the splayed skylight wells. No underwater pool fixtures are integrated within the pool itself. Instead, the large amount of light from above looks to provide enough illuminance to light the depth of the pool. Lensed compact fluorescent downlights line the perimeter of the pool deck to provide illumination to the deck seating areas. Fig. 9: Pool Floor Plan With Dimensioning

Manual override of the automatic shutoff is also possible for up to four hours as required again by the standard. No photocell sensor is used in combination with the skylighting. Thus, energy may be lost unnecessarily when sufficient daylight to illuminate the pool area is available. Daylighting Elements Unlike the previous spaces, the pool area contains no windows to the exterior. It does, however, take advantage of three North-facing ridge-type skylights with Low-E glass (see architectural surfaces.) These skylights are centered above the pool areas and consist of skylight wells that splay near the bottom. Total LLF

43 Pool Continued Design Criteria and Goals Color Appearance (and Color Contrast) (Somewhat Important) The rendering of colors within a swimming pool area is important to create a strong contrast between backgrounds and the immediate task of swimming. Color contrast should make distinguishing points in the pool as well as along the pool deck quite easy. By maintaining a strong color contrast between the pool and surroundings, safety hazards are made more noticeable, and swimming perception is likewise increased. Daylighting Integration and Control (Important) While daylight from the provided skylights is desirable, unwanted glare from direct and reflected light can cause performance and safety problems. Daylight falling onto the pool can be distracting to swimmers causing discomfort during long exposure times. Meanwhile, reflected sunlight into the eyes of a lifeguard can hinder his or her ability to locate safety issues and react quickly. As the skylights are North-facing, direct sun will not be an issue. However, the impact of daylight and its effective use in the space should be evaluated. Direct Glare (Very Important) As mentioned with the daylight, direct glare can cause disorientation and discomfort for swimming recreationally. It also has the potential to hinder the vision of a lifeguard overseeing the activity of the pool area. Light Distribution on Task Plane (Uniformity) (Important) The luminance of the horizontal swimming plane should be uniform across the pool to easily distinguish safety concerns and to avoid distraction for the swimmer. While swimming, swimmers may become distracted by changes in luminance at different points along the water s surface. Additionally, shadows along the water surface can mask potential drowning victims. Additionally, without an even distribution of light along the pool floor, slippery surfaces and other walking hazards can be left unseen. Similarly, the pool, itself, must be set apart from the pool deck to avoid the hazard of slipping on wet surfaces near the edge. Modeling of Faces or Objects (Important) While horizontal luminance is of primary concern, the modeling of faces and objects for safety reasons must not be overlooked. Reflected Glare (Very Important) Reflected glare is a primary safety and functional concern of the swimming pool area. As the water surface acts as a highly specular surface, light falling upon the plane can cause glare and reduce the ability of the lifeguard to see certain objects on the water s surface or beneath it. The reflected glare from wet surfaces can also decrease a visitor s ability to perceive potential slipping hazards possibly causing serious injury. This is especially true concerning young children who may be running around in the area. Surfaces surrounding the pool surface should have low reflectance values and matte finishes to decrease the reflected glare back to the swimming plane.

44 Pool Continued Shadows (Important) Unwanted shadows along the pool periphery as well as within the pool itself can create a safety hazard for swimmers. The lifeguard must have a clear view of the pool area and surrounding deck to perform his job effectively. Shadows can mask potential safety hazards. Maintenance (Important) Proper maintenance of pool luminaries must be considered in any design. As fixtures will repeatedly come in contact with direct water or water vapor within the air, each fixture must be corrosion resistant. All luminaries are required by code to be UL wet-rated to satisfy this criteria. By placing the luminaries directly above the pool, changing lamps after burnout could cause major complications. If a lamp is not immediately replaced, the hindrance of the uneven illuminance as well as safety issues may be of concern. However, changing these fixtures can become even more complicated as maintenance personnel must elevate themselves above the pool s surface. If fixtures are to be placed in these areas, their lamps should possess long lamp life and generally worry-free maintenance. A system without this hindrance upon lamp removable is even more desirable. Illuminance (Horizontal) As a multidirectional ground-level sport, swimming demands well-distributed horizontal illumination. Under the IESNA Handbook, Broadway s Plaza recreational swimming designation demands 15 cd/sq.m luminance maintained over the pool surface. The pool deck should be lit to 30 fc at 3 ft above the floor to provide enough light for safety concerns. However, due to the private nature of this area (for use by apartment renters only,) these values may be a bit high. To create an even more private atmosphere, the pool deck may fall to illuminance levels of 5-10 fc with the pool itself to 5-10cd/sq.m. However, it is also extremely important to strongly emphasize the water s edge from the deck to avoid slipping and other hazards. The actual value is not the only concern when it comes to lighting levels. The overall design of the pool area should have a coefficient of variation (CV), or weighted average of relevant illuminance values, of 0.3 or less. Additionally, according to the IESNA Handbook for recreational pool areas (Figure 20-2, category IV), the maximum to minimum ratio (UG) of illuminance values should fall at 4:1 or less for 3 ft above the pool area. Once again, these values would appear stringent for a private facility such as this, and may be stretched if safety is not compromised. Illuminance (Vertical) (Important) Although vertical illuminance does not affect the act of swimming, maintaining a value of 3 fc along the face is important for safety reasons. Lifeguards will be more prone to notice facial expressions indicating a safety problem with a swimmer. ASHRAE 90.1 Power Density Evaluation ASHRAE 90.1 Power Allowance: 1.1 W/sq.ft.

While the space succeeds in meeting the requirement of 15cd/sq.m. of maintained luminance over the pool surface, the ideas of variation of light are not entirely met. To satisfy IESNA criteria for a casual swimming atmosphere, a coefficient of variation (CV) of 0.3 or less is desired. While the smaller pools and seating areas comply with this recommendation, the lap pool ceiling CV is far beyond the suggested value and may prove to be a distraction to those swimming as well as to the lifeguard looking out for their safety. Likewise, the maximum to minimum ratio for the deck areas falls beyond the 4:1 recommendation by the IESNA. While this value may prove to be a bit stringent for this private scenario, a readjustment of all lighting levels may help the luminance ratios to better meet this suggestion. The values for CV and UG for the surrounding pool deck and ceiling must be evaluated to minimize the chance for injury due to glare or insufficient light along portions of the deck. Additionally, daylight falling upon the pool surface may work to further increase the CV and UG. Dim perimeter lighting will starkly contrast the bright daylight illumination reflected in the pool surface. Thus, it is important to study the daylight present in the space to work to minimize these problems. Although not task intensive, seating area illuminances should be increased to coincide with necessary ratios and safety precautions. The pool area complies with ASHRAE 90.1 in terms of both power density and controls. The lighting control system can automatically shut off the pool lighting if a situation, such as vacancy, occurs to warrant this. This action can drastically save power in a space that will not always be occupied. The power density of 1.08W/sq.ft. also falls below the 1.10 W/sq.ft. allowance, allowing the space to fully comply with ASHRAE standards.

48 Exterior: Ground Level Façade and Roof Existing Lighting Overview Site lighting is not complex for either the ground-level facade or the roof. The roof is lit with FAA approved flashing red obstruction beacons. Vaportite compact fluorescent jelly jars provide illumination for maintenance to the mechanical equipment on the roof. High pressure sodium globe pole fixtures along the sidewalk and roadway edge, meanwhile, light the ground level. The decorative wall sconces around the building are fluorescent with the addition of two adjustable par metal halide lamps to the fixtures nearest to the main entrance. Recessed steplight fixtures are provided along the service entrance as a safety precaution.

When sufficient daylight is not available on the sensor for a dead band time of two minutes, the photocell will instruct the beacons to become operable. Manual system override of the photocell is also possible for safety regulations. This photo sensor control complies with ASHRAE 90.1 requirements. Meanwhile, single-pole switching that may be automatically shut off by the building automation system controls the wall-mounted fixtures found along the roof. However, this means of shut off is not compliant with the standard requirement of a photo sensor or time switch for exterior applications. The ground-level facade lighting and pole-mounted fixtures are controlled by an astronomical time switch set to astronomic sunset and sunrise as required by ASHRAE A photocell is also listed as being operable for the exterior lighting on the lighting control system panel, yet is not located on the construction documents. The addition of this photocell is not necessary even if not being utilized, as the lighting is already compliant with ASHRAE Daylighting Elements All window elements along the lower facade and roof are Low-E insulating glass (see architectural surfaces.) This glass is inlaid with spandrel panels between floors in the curtain wall of the front entrance. The canopy, meanwhile, is heat-strengthened laminated glass with a translucent white layer in the center. No daylight elements are included in the architecture of the building.

51 Exterior Continued Design Criteria and Goals Ground-Level Facade Appearance of Space and Luminaires (Very Important) The entrance and exterior facade are primary areas seen by potential residents. Many of these potential residents will immediately judge the entire building by the appearance of its exterior lighting. Maintaining the impression that Broadway Plaza is a luxury building filled with amenities, the lighting must appear prestigious in choice of luminaires and appearance. The facade lighting should immediately send the striking message that Broadway Plaza stands apart as an artistic beacon in the community. Additionally, the lighting should create a safe and comfortable atmosphere, making residents and passerbies content and secure. Color Appearance (and Color Contrast) (Important) The color appearance of Broadway Plaza can play a large role in its marketability. The facade lighting may take on any color in order to achieve the goal of setting Broadway Plaza apart from neighboring structures. However, the actual color appearance of building materials under any lamp color should be considered to create the desired mood and atmosphere. Meanwhile, the entrance canopy must provide a high color rendering of 70 CRI to compliment facial rendering of those entering the space. Direct Glare (Important) Direct glare should be avoided in any area where people will be operating motor vehicles. As Broadway Plaza is surrounded on all sides by traffic, inappropriate site lighting can cause momentary blindness for drivers, creating a hazardous situation. Additionally, the building functions primarily as a residence. Residents should be given the opportunity to enjoy the remarkable view rather than look directly into a direct glare source. Direct glare is of especial concern when dealing with the pole fixtures. The clear spheres can become glare bulbs causing hazardous conditions and discomfort to everyone within the vicinity. Light Distribution on Surfaces (Very Important) Light distribution along surfaces should help to strengthen the architectural statement set forth by Broadway Plaza. Accent may be placed on specific vertical elements to emphasize the size of the structure. While remaining as an artistic statement, the light distribution should take into consideration the surrounding lighting and its integration in the community appearance. As a general rule, luminance ratios should not exceed 20:1 in order to decrease the possibility of annoyance and creation of safety hazards. Light Pollution/Trespass (Very Important) Not only should light not trespass into the sky, the exterior lighting should not disturb residents during the night. Every effort should be made to keep light out of resident windows. Replacement of the pole luminaires and various wall-mounted fixtures with upward distributions would reduce this concern. Modeling of Faces or Objects (Important) To accurately view surroundings and those around them, faces should be modeled with adequate illuminance for facial recognition and expression. This will maintain the feeling of safety and security that should dominate the facade appearance.

52 Exterior Continued Points of Interest (Important) As the canopy and skybridge stand apart as artistic statements of the building, it is important to bring focus to them. At the moment, these particular aspects are neglected by any special means of lighting. Shadows (Important) To promote a feeling of security, dark shadows should be avoided along the entire facade of the building. This is especially true near major building entrances such as the main canopy and skyway. These areas, if left in shadow, will discourage visitors from using the grounds. Surface Characteristics (Important) Expensive materials dominate the facade and thus, attention should be drawn to these features. Changes within the facade material should be considered and perhaps highlighted. Illuminance (Horizontal) A value of 5 fc along the entrance canopy should be achieved for safety concerns. Surrounding areas should strive to maintain a value of 3 fc. Illuminance (Vertical) Vertical illuminance for facial rendering safety should not fall below 3 fc. Coinciding with the somewhat dark surroundings and light surfaces, an average target illuminance of 2 fc is desired along the facade. Roof No specific design criterion exists for lighting a roof facade. However, several factors must still come into consideration when lighting the roof area. Code and Obstruction Lighting As Broadway Plaza is a high-rise building, obstruction lighting is required. FAA beacons are currently installed. It is important to evaluate the possibility to change these fixture types and the overall look of the roof to meet Rochester, FAA, and national codes. Light Trespass Light trespass on the roof will not cause much distraction to those on the ground, but will certainly pose a threat to aircraft that may be flying in the area. Distractions by light trespass should be avoided. Safety Maintenance concerns on the roof require that portions of the roof be lit to adequately light mechanical equipment. When malfunction occurs, adequate lighting must be provided to the equipment surface to allow maintenance to perform its duties without sufficient need for task lighting. A value of at least 5 fc along the work plane center and chiller location is preferable. Appearance Like the ground-level facade, the roof appearance should coincide with the overall luxurious theme of the building. Colors and appearance should not stray far from the ground-level exterior lighting scheme.

While the luminaires along the facade are prestigious in appearance, they do not fully accentuate the architecture and distinctive surfaces of Broadway Plaza. Facade lighting does not go far beyond the first floor due to glare potential, but with proper design, the entire lower facade may be accentuated without distraction to residents. The current lighting system also does not highlight the canopy and skybridge. As modern artistic statements, these areas should be lit to provide a focal point. Potential residents would be more compelled to explore residence in a space that was striking and unique. In addition to not fulfilling the design criteria set forth, the lighting system does not satisfy the illuminance requirements made by the IESNA. With two lighting calculations completed (one without assistance of interior lighting and one with the assistance of light from the lobby), it was determined that neither condition met the desired horizontal canopy entrance illuminance of 5 fc. Even with the addition of lobby lighting, this value only amounted to 2 fc with much of the sconce light lost to the upward surroundings. Vertical illuminances for rendering of faces is even less than the horizontal values. With the necessary light loss factors set in place, the lighting system will not meet requirements for safety concerns. Another area of concern may be seen in the area of light pollution, trespass, and direct glare. Broadway Plaza, like many of its neighboring institutions utilizes high pressure sodium polemounted luminaires. As composed of clear glass, these highly luminous sources can prove hazardous to drivers as well as pedestrians distracted by the source. Additionally, unwanted light is allowed to trespass into the upward plane and may cause uncomfortable glare in residential windows. If not required by the city, new pole fixtures that are not direct glare should be considered.
