3 Brian Franco Lighting Electrical Option Dover Downs Hotel and Conference Center, Dover, DE Faculty Consultant: Dr. Moeck Existing Conditons Report Executive Summary The existing lighting conditions report describes in detail all lighting systems for the four spaces that I chose to study and eventually redesign. The information in this report includes luminaire schedules, reflected ceiling plans, design criteria, furniture layouts, control diagrams, critiques of existing conditions, and more. For my special purpose space I chose the performance hall at Dover Downs. For my circulation space I chose the main lobby. The building does not have a large office space, so after some discussion with my faculty advisor I chose the lobby bar and lounge which is adjacent to the lobby. My exterior space is the front façade. However, I am not quite sure about the scope I will work with, it may get narrowed down to the porte cochere out front of the lobby. To compile this report I used AutoCAD to make 3d models and then put them into AGI32 to analyze the existing conditions. I referenced the IESNA Lighting Handbook and the ASHRAE 90.1 standards on allowable power density. The result of this report is a large amount of knowledge gained on the conditions of the spaces that I plan to redesign.

4 Performance Hall The Rollins Center is the name of the multi-purpose performance hall housed inside of Dover Downs. The performance hall is one of the highlights of Dover Downs. It is located close by to the lobby for convenience. The hall is a large open space (18,000 sf) open above to the second floor. The ceiling is very detailed and resembles the lobby ceiling with a large dome in the center and several architectural coves surrounding. The hall can be divided into three sections - 7,200, 4,800 and 6,000 square feet. In the center of the room a boxing ring can be set up, with seating for 2,000 fans around it. Another set up allows tables to be arranged to host up to 1,000 people for dinner, or 1,500 guests for a reception, 100 exhibits for a tradeshow, or 1,500 seats for a concert. Extending from the back wall are 550 retractable arena seats. The whole thing including the chairs folds up compactly into the back wall, but when open, it is carpeted. The hall is a beautiful space that is extremely versatile. Along the side walls there are several large doors leading into pre-function space that can also be used for conferences. There is a permanent stage in the front of the hall with another temporary one below that, which can extend into the room for additional stage space. The walls of the performance hall are eight inch steel stud framing and batt insulation and the floor is six inch reinforced concrete over four inch crushed stone and a vapor barrier. Existing Lighting System (see lighting plan) The lighting for the performance hall is all overhead lighting and all the non-decorative lighting is recessed incandescent. Throughout the space there are 124 adjustable downlights with one 250W PAR38 flood lamp per luminaire (G6). Above the west wall are 10 of the same luminaires with one 250W PAR38 spot lamp per luminaire (G6A). Both the spot and flood lamps are krypton filled bulbs with a color temperature (CT) of 2700K and a color rendering index (CRI) of 100. In the center of the room, suspended from the center of the dome, is a huge incandescent 4800W crystal chandelier (F7), which was supplied by the owner. No specifications are provided for the chandelier since it is mainly for decorative purposes. In the cove of the central dome, surrounding the chandelier, there is a system of low voltage flexible xenon striplights (F9). The striplights consume 15W/ft 2 and have a CT of 2400K. Junction boxes are required to run the wiring through the building structure and remote transformers are located above the adjacent accessible ceiling. In each of the four corners of the hall there are identical architectural coves. Each cove has an incandescent 950W crystal chandelier (F8) suspended from the center surrounded by a similar system of the same striplights that are in the center dome. The entire performance hall lighting system is run by a Lutron Grafik Eye dimming system. More information can be found on the dimming system in the lighting control diagrams. The system can achieve a number of different light outputs for the vast number of activities that take place in the space.

5 Room Surface Reflectances White wood trim (ceiling and walls) 85% Yellow wall paper 60% Red/blue carpeted floors 10% or lower Black curtain (back of house) 4% Blue dome ceiling 50% Blue stage curtain 6% Black wood stage 2% Design Criteria The main theme of the performance hall should give a feeling of prestige and class. The beauty of the architecture of the space does much of the work on its own, but it is the job of the lighting system to really make the space stand out. The style is reminiscent of an older theatre from the days when fancy wood working was more commonplace. A modern, creative lighting system, coupled with this nostalgic look, should make the space shine as a beacon in the entertainment industry of Dover, DE and the surrounding area. The performance hall falls under a few different task classes according to the IESNA Lighting Handbook. It can be considered an auditorium, used for assembly and social activity, an exhibition hall, a dance hall or ballroom, and even a boxing ring. System control and flexibility This is perhaps the most important of the criteria for the reasons listed above. Also, the space can be divided into three separate spaces and therefore must have the capability to change in three separate ways. Appearance of space and luminaires This is also very important to the success of the lighting design. Thousands of guests a year will come to the performance hall to have a good time, expecting a high class, architecturally beautiful space. Luminaires should not stand out and the space should have an overall feeling of welcome. The unique ceiling should be highlighted with the lighting. Color Appearance and Contrast This goes hand in hand with the appearance of the space. Colors should have a natural warm feeling to allow for the intricate wood work to stand out. The bright red, blue, and tan rug and the textured yellow wallpaper should keep their real colors under the light. Light Distribution of Surfaces All surfaces should have a fairly even distribution of light on them. This is especially true for the workplane, which in this case is where guests of the performance hall eat. The walls and ceiling should also be even to add to the pleasant appearance of the space. Modeling of Faces or Objects This is important because for the most part when people come to the performance hall they will be dressed up and looking good for their night out. Bad lighting can make even the most beautiful people look bad so it is important that the modeling of faces is flattering. Sparkle/Desirable Reflected Highlights These things can help the space look better and more pleasing to the eye. It could be the shimmer of the wallpaper under the light, or the glow of the dome reflected back down into the center of the room, these types of extras can really liven up the space for those big nights.

6 Accent Lighting There are several column-like structures protruding from the wall in this space that accent lighting could really make stand out and look nice. The architectural coves and the dome also benefit from accent lighting. Points of interest It may not be necessary, but the lighting could highlight the exits throughout the space, making their location clear to anyone present. Vertical Illuminance For all the different setups of the performance hall there should be a vertical illuminance of at least 3fc. There are no real tasks that take place that require high levels of vertical illuminance. However, several of the patrons of Dover Downs are senior citizens and therefore may need higher illuminance levels, both vertical and horizontal. Horizontal Illuminance The control system in the space should be able to achieve a range of horizontal illuminances. The levels should be able to go as low as 3fc for use when the space is a ballroom or concert hall. If the space is being used as an exhibition hall there should be a horizontal illuminance of at least 10fc. Also, when dinner is being served in the performance hall there must be adequate light on the table for eating and drinking. Direct and Reflected Glare There is no real issue with glare in this space, especially because the room is over twenty feet in height. Daylight Integration It may be difficult to integrate daylight into this space since there are many times when the room needs to be dark. However, there is nothing above the performance hall roof and therefore the possibility to open up the ceiling to daylight is there.

11 Evaluation of Existing System Results from AGI32 Lighting Analysis: (Illuminances in fc) West Wall: avg = 2.01 max = 10.5 East Wall: avg = 1.68 max = 4.6 Workplane (table top) for front two thirds of space: avg = max = 33.9 min = 3.1 Floor for front two thirds of space: avg = max = 33.2 min = 4.0 These are the renderings from AGI32. They are somewhat misleading because there is entirely to much reflection from the red carpet. However, they so show approximate light levels in the space and show the appearance of the space. Notice the detail of the columns and especially the ceiling coves.

12 Evaluation Summary The existing conditions in the performance hall are fairly decent. The Lutron lighting system allows for several different lighting conditions depending on the event. The space itself is a gorgeous piece of architecture from which the physical luminaires do not detract. The crystal chandeliers add sophistication and class to the space. However, the color appearance of the space could use improvement. When the system is at its lower (dimmer) end the light takes on an orange/red quality that washes out the surface colors leaving a rather unpleasant look. The distribution of light around the space is adequate, but still could be better. The ceiling is left to dark in the shadows around the edges of the room even though that is perhaps the most exquisite part of the performance hall. Also, when the partitions are down there are large, obnoxious hot spots towards the top. This should be designed to look good when the partitions are up or down. There are accents on the columns on the west wall, but only from above. If the accent was even from above and below the column would really stick out and give some sense of depth to that wall. There are no accents on the columns on the east wall. There is more then enough horizontal illuminance on the table tops that would be used for a dinner event. If the levels are too high they can easily be dimmed to reach proper levels. The vertical illuminance is also adequate, although the walls, besides where the accent lighting is, are fairly dark. Horizontal illuminances are not particularly even throughout the space which is bad for the wanted even light distribution. This space could be improved by adding a few more downlights to somewhat even things out. Also, the system of column accent lighting on the west wall should be duplicated for the east wall. And perhaps these columns could use some uplighting to really bring out their depth. Overall the lighting system for the performance hall is nice but could certainly be improved on. Power Density From ASRHAE IESNA Standard 90.1 from 1999: - Allowable lighting power density using the space by space method for a performing arts space is: 1.8 W/ sq. ft. plus 1.0 W/ sq. ft. for decorative lighting such as chandeliers, sconces, and artwork lighting. - Dover Downs Performance Hall Power Density: o Area of Hall = approx. 18,000 sf o Non-decorative lighting: 33,500 W o Power Density = 33,500 / 18,000 = 1.86 W/ft2 non-decorative, which is only slightly over the limit o Decorative lighting = 10,500 W o Power Density = 10,500 / 18,000 -=.583 W/ft2 for decorative.

13 Lobby The lobby serves as the main entrance to the building. It is a two story space with a sweeping staircase leading up to the second floor and a large glass door entrance with a revolving door in the center. The glass entranceway is under the valet parking driveway and therefore receives minimal direct daylight. The main space in the lobby is under an intricate dome structure with windows surrounding the bottom of the dome. The structural support comes from several columns located toward the back of the lobby space. The lobby is a beautiful, inviting space decorated with a fancy marble floor and a brilliant chandelier hanging from the center of the dome structure. It is mainly a circulation space, serving as a welcoming point for all guests of Dover Downs. In the northeast corner there is the hotel registration desk. Above the registration area there is a row of windows that look into the second floor gourmet restaurant. Throughout the lobby there are groupings of sofas, chairs, tables and several potted plants. At the foot of the stairs there is an antique decorative gazebo. There are a few large pieces of artwork on the walls. The lobby has access to the casino, the second floor, administrative offices, the elevators, a bar/lounge, the Lobby Shop, and an area used as prefunction for the performance hall. Existing Lighting System (see lighting plan) The existing lighting in the lobby, like the performance hall, is almost exclusively incandescent recessed downlights. However, there is daylight in the space from the windows wrapped around the base of the dome and from the glass of the vestibule entryway. There may also be electric light contributed to the space from adjacent spaces, but only negligible amounts. The main system of incandescent recessed downlights throughout the lobby is the same as in the performance hall. There are 70 of the same adjustable downlights with one 250W PAR38 flood lamp per luminaire (G6). There are also 40 of the same downlights with a 250W PAR38 spot lamp instead of a flood (G6A). These have a CT of 2700K and a CRI of 100. Above the diagonal northwest wall there are 6 halogen lensed wall washers with one 250W PAR38 flood lamp per luminaire (G7). These have a color temperature of 2880K. On the same wall there are 3 120W decorative incandescent wall sconces (F39) which were provided by the owner. The dome is the centerpiece of the lobby and is highlighted with decorative lighting. There is an 800W incandescent chandelier (F21) suspended from the middle surrounded by a single row of dimmable 25mm cold cathode tubes (C1) mounted in the architectural cove. The operating transformer for these is concealed behind a ventilated access panel that can not exceed an ambient temperature of 100 degrees F. The cold cathode tubes have a CT of 3500K and a CRI of 85.

14 Stairway and Second Floor Balcony Lighting the stairway up to the second floor balcony are 5 recessed incandescent adjustable downlights with one 120W PAR38 flood lamp per luminaire (G8). These have a CT of 2675K and a CRI of 100. Above the balcony there are 7 recessed incandescent adjustable downlights with one 90W halogen lamp per luminaire (G10). These have a CT of 2850K and a CRI of 100. There are also 2 low voltage adjustable accent downlights with one quartz 50W MR16 lamp per luminaire (G3), aimed at artwork on the walls. These have a CT of 3000K and a CRI of 100. Along the back wall of the balcony are 4 120W decorative incandescent wall sconces (F29) which were provided by the owner. Room Surface Reflectances White wood trim (ceiling, walls, columns) 85% Off-white wall paper 77% Red wall paper 15% Beige marble tile floor 70% Dark brown marble tile floor 20% Carpet 10% or lower Dome ceiling 80% Brown wood table tops 30% Furniture 5% or lower Exterior and interior glass 9% Daylighting Details There is a small daylight contribution from the sixteen windows surrounding the bottom of the dome. These windows are approximately 4 6 x 4 10 each. They are approximately 4 8 from the bottom of the entire clerestory which is the plane of the ceiling for the rest of the lobby. The walls of the clerestory are 85% reflective. The windows have a visible transmission of 88%. This allows for some daylight in the lobby, but integration with the existing electric power system is unlikely unless changes are made to the structure. There is another small daylight contribution from the entrance. The entrance is 31 wide and 12 tall. There is 8 of vestibule space between the layers of glass. However, since the entry is under a large overhang the contribution is negligible in the lobby. If the lobby were redesigned to allow more skylights the daylight from the entryway could contribute to a partial-daylight system.

15 Design Criteria Appearance of Space and Luminaires Like the performance hall, the lobby must be visually pleasing. The lobby is perhaps the space that people will remember the most when they leave Dover Downs. It should be well lit and easy to maneuver through no matter which direction you are headed. The luminaires should not look cluttered. Decorative lighting should be plentiful in the space. Color Appearance and Contrast The lighting should bring out the true colors of the materials around the lobby. Most of the people walking through the lobby will have just come from outside, so the lobby should offer a smooth transition from sunlight to electric light. Daylight Integration There is already some daylight entering the space directly through the glass in the dome and indirectly through the glass entryway. As mentioned above, it would be nice to have a smooth transition from outside into the hotel, which could be accomplished by allowing more daylight into the space. There is nothing above the roof of the lobby and there daylighting is feasible. Direct and Reflected Glare Glare is an issue in the lobby. Sunlight off the marble floor can cause a glare problem as people walk into the lobby. Glare can be distracting and leave patrons of the hotel with a sour feeling as they walk through the lobby. Light Distribution on Surfaces Light distribution should be as even as possible, especially on the floor, stairs, and tables that are throughout the space. Light Distribution on Task Plane There are several sets of tables and chairs throughout the lobby which may or may not be used for paper tasks and/or reading. Light should be evenly distributed over all these surfaces. Modeling of Faces or Objects People are in and out of the lobby all day. Like the performance hall these people should look as good as possible under the light. Also, plants and furniture around the room should be lit so that it appears comfortable. Points of Interest There are several points of interest in the lobby. There is the main entrance, the staircase, the registration desk, the entrance to the casino, the entrance to the pre-function of the performance hall, and the entrance to the lobby bar and lounge. These spaces should be clearly identifiable with the help of lighting. System Control and Flexibility This is probably not very important because the lobby will most likely always remain lit. Perhaps the system could be dimmed at night to save power. If daylight became more of a factor in the space an integration control system may be applicable. Sparkle/Desirable Reflected Highlights - Anything that will make the lobby and therefore all of Dover Downs look better to patrons is important since the prosperity of the hotel depends a lot on happy returning customers. Accent Lighting Throughout the lobby there are several large round columns that really give the space a strong, resounding feel. They would look even better and stand out even more if accent lighting was used in someway to highlight this architecture. Horizontal Illuminance This should be about 10fc, possibly higher to adjust for the poor vision of some older people.

The rendering on the right below is a view from the 2 nd floor of the casino entrance and registration area.

21 Evaluation Summary The lighting in the lobby is very similar to that of the performance hall in that the majority of the fixtures each space uses is the same. However, I think it works out better then the performance hall. The space looks great and is very welcoming when you enter. The lighting around the space leads your eyes from one thing to the next until you ve eventually taken it all in. The one negative aspect of the lobby lighting is the failure to take advantage of daylight. There is a dome that is the highlight and center piece of the space, however, barely any useful light reaches the space. The dome actually causes a nasty glare during the afternoon hours. A system that really utilized daylight would be great in this space. Besides the glare from the sunlight there is a fairly even distribution on the room surfaces. Both furniture level calculation grids from AGI 32 (above) show a relatively even distribution on what could potentially be a workplane for guests of the hotel. They will likely not encounter any glare or any serious uneven distribution patterns. The lighting does provide good facial and object rendering. This is probably because the system is high above the floor and the walls are highly reflective. There is not a dominant direction of light that would cause unwanted shadows on faces or objects. Points of interest around the lobby, such as the entrance to the lounge and the entrance to the casino are marked by wall sconces that hang on either side of the doorways. The huge chandelier suspended from the center of the dome decorates the space nicely, adding the extra sparkle and shimmer to make the lobby look fresh and welcoming. Besides at doorways, there are wall sconces throughout the space that add to the overall grandeur that is the main lobby of Dover Downs. Horizontal illuminance levels are more then enough which is good because of the volume of senior citizens that come through the space on a regular basis. Power Density From ASRHAE IESNA Standard 90.1 from 1999: - Allowable lighting power density using the space by space method for the lobby of a hotel is: 1.7 W/ sq. ft. plus 1.0 W/ sq. ft. for decorative lighting such as chandeliers, sconces, and artwork lighting. - Dover Downs Lobby Power Density: o Area of Lobby = approx. 8,800 sf o Non-decorative lighting: 30,230W o Power Density = 30,230 / 8,800 = 3.43W/ft2 non-decorative o Decorative lighting = W o Power Density = / 8,800 -= 0.33W/ft2 for decorative. This power density is way over the allowable limit, probably because of the use of incandescent lamps instead of fluorescents. In the redesign of this space achieving a lower power density will certainly be a goal.

22 Lobby Bar and Lounge Adjacent to the lobby is the lobby bar and lounge. This is a space where visitors of Dover Downs can relax and have a few drinks while they chat with friends or watch sports on television. The interior designer of the space intended it to be geared more towards men then women hence it has a sort of cigar parlor appearance to it. The lounge and bar are slightly separated by a small segment of wall. The bar is a quarter circle backed into the southeast corner. There is a fireplace on one wall in the lounge area and several pieces of artwork throughout the space. There are also chairs, tables, couches, and plants throughout the space. Existing Lighting System The general lighting is provided by 26 low voltage adjustable pinhole accent downlights with one quartz 50W MR16 lamp per luminaire (G2). These have a CT of 3000K and a CRI of 100. Outside the entrance to the lounge, in the lobby, there is one 120W incandescent wall sconce (F39) on either side. There are 11 similar 120W incandescent wall sconces (F30) within the space. All sconces were provided by the owner. Also provided by the owner was a 240W incandescent pendant (F40) which is above the entryway in the lounge. In the bar area there are two 15W incandescent picture lights (F3A) which are each mounted to the back of a picture frame. These have a CT of 2700K and a CRI of 82. Room Surface Reflectances Dark brown wood (walls and ceiling) 5% Floor 5% Brown wood table tops 10% Other furniture 5% or lower Brown wood bar top 10%

23 Design Criteria Currently the theme of the bar is very masculine. I would like to do away with that style and go more in the direction of modern, almost trendy. The space should be like a canvas for the light and it should portray a very modern, cutting edge feel, while at the same time remaining subdued and comfortable. System Control and Flexibility Depending on the time of day, the activity taking place, and the type of customers this bar needs to be able to achieve a range of different light levels. Appearance of Space and Luminaires The bar/lounge should have a very relaxed appearance to it, and the luminaires should hardly be visible, except for the decorative lighting. I want the space to appear modern and have a catchy aspect to it so that once someone spends some time in the lounge they will not forget it. The lighting should draw people in from the lobby, while at the same time not reveal to much about the space until you are fully inside. Glare Glare should not be a problem, since the light levels are typically very low, however, glare off the bar or on the television should be considered and avoided. Color Appearance The space should have a very warm feel to it that makes one feel very comfortable and at home. There should also be color highlights, which can be for each individual table, behind the bar, or in the general style of the lighting system. Points of Interest The bar itself is obviously a point of interest and should be lit accordingly. Another point of interest may be the fireplace which should be lit with slightly higher light levels then the rest of the space even when there is no fire burning. Modeling of Faces or Objects There should be an attempt to make faces look good, even though there are minimal amounts of light. One idea is to light tables from under the table, weather it be through the glass surface of the table or by some other means. Shadows Bars are known as being dark places and there are reasons for that. Shadow is a necessary aspect of any bar s lighting. There should be more shadow spots then bright spots and therefore the bright spots will draw even more attention. Vertical Illuminance The vertical illuminance can be very low. Horizontal Illuminance This should be around 3fc for a bar or table top. More then that is bright for the style of bar. Less then 3fc may be okay.

27 Evaluation of Existing System Results from AGI32 Lighting Analysis: (Illuminances in fc) Bar Top 1 avg = 2.83 Bar Top 2 avg = 4.78 Table top 1 avg = 6.48 Table top 2 avg = 5.87 These renderings of the bar/lounge are from AGI32. Evaluation Summary Of the four spaces studied in this report the lobby bar and lounge has the worst existing conditions. The light levels are very low and the distributions are terribly uneven. There is a Lutron dimming system in place, but even at its maximum there are some very low

28 illuminance values at certain points. These low light levels totally eliminate any chance of grabbing the attention of people in the lobby. From the lobby the bar and lounge look like a dark closet. The appearance of the space, besides the low light, is proper for a bar lounge, however it is rather typical and boring. There is one interesting luminaire, which is a custom pendant suspended from the ceiling right inside the entrance. There is virtually no color in the space. The walls are so dark that any light in the space takes on the characteristics of the wall and the whole room looks sort of brown. The bar itself tends to stand out which is good, because that is the main point of interest in the space. There is also lighting behind the bar in the form of two wall sconces. I want to make the bar a focal point for the lounge so that as soon as one enters the space they know exactly where they need to go to get a drink. From the light levels in the space the facial and object rendering must be bad. There are probably a lot of shadows throughout the space that fall onto people s faces if they are sitting in the wrong place. On average there is enough horizontal illuminance in the space on the bar and on the table tops. Bars in general need little ambient light so the lower averages of 2.83 and 4.78 are sufficient. Overall the lighting in the bar and lounge is bad and in need of a change. As mentioned previously I would like to take the lighting of the bar in a whole new direction. Since Dover Downs is after all a casino, I feel that as a whole it could use some more interesting lighting and where better to start then the bar. I want to put in colors and raise the ambient level somewhat. I also am interested in looking in to lighting the tables from within the table itself, or underneath a glass table top. There are several options to make this bar into a more fun and therefore more popular and profitable space. Power Density From ASRHAE IESNA Standard 90.1 from 1999: - Allowable lighting power density using the space by space method for the lounge of a hotel is: 1.4 W/ sq. ft. plus 1.0 W/ sq. ft. for decorative lighting such as chandeliers, sconces, and artwork lighting. - Dover Downs Lobby Power Density: o Area of Lounge = approx sq. ft. o Non-decorative lighting: 1300W o Power Density = 1300W / 1070 sq. ft. = 1.2 W/sq ft non-decorative o Decorative lighting = 1710W o Power Density = 1710W / 1070 sq. ft. = 1.6 W/sq ft which is over the limit, but with some tradeoff with the non-decorative lighting there should not be a problem.

29 Front Facade The front façade acts as a beacon for Dover Downs to the surrounding city of Dover. On the top of the hotel tower there are two roof gazebos that are fully lit at night. Underneath the front gazebo there is a large sign that says Dover Downs. Extending out towards the parking lot is the porte cochere, which covers the valet parking lane and the main entrance into the lobby as well as an entrance into the casino and into the performance hall pre-function area. There are three skylight openings in the roof in front of the lobby vestibule to allow for some daylight. Out front of the porte cochere is a fountain in front of three arches, which together with the decorative stone banister on top of the porte cochere and the dome from the roof of the lobby, mimics the hotel roof gazebos very nicely. Underneath the porte cochere several large columns line the valet parking driveway. Since the hotel tower sits back from the roof line of the front of the building there is plenty of room on the second story roof to provide convenient locations for up-lighting of the hotel tower. The exterior of the first and second floors on either side of the porte cochere are up-lit from the ground level. Existing Lighting System The lighting of the exterior façade is a large job since Dover Downs is such a large building. Overall there are 15 different fixtures used to light the porte cochere, the front perimeter, the hotel tower, and the driveway leading up to the porte cochere and along the front of the building. The majority of the lighting is strictly for decorative purposes and therefore is not included in the light levels analysis. The CRI and the CT are only included if the light is not for decorative purposes. All the metal halide fixtures use integral magnetic ballasts and all the fluorescent fixtures use integral electronic ballasts. Porte Cochere In the front of the porte cochere there is a water fountain with three supportive arches behind it. Around the perimeter of the water fountain are 16 56W recessed-in-grade metal halide adjustable uplights (M18B). In the fountain, under the water, there are 8 250W halogen wet/dry fountain lights (M19). Behind the fountain and around the edges of the driveway there are 12 75W metal halide bollards (M17A). These have a CT of 3000K and a CRI of 80. The general lighting under the porte cochere is supplied by 52 90W metal halide open reflector downlights (K1). These have a CT of 3000K and a CRI of 80. In front of the entrances into the building are 5 custom suspended dome-shaped pendant luminaries with 8 320W fluorescent lamps per luminaire (F34). Hanging from the side of the exterior canopy skylights are 18 vertical wall sconces with 2 52W compact fluorescent lamps per luminaire (F17). On either side of the entry into the lobby is one vertical wall luminaire with 3 180W incandescent lamps per luminaire (F18). Concealed in the coves around the perimeter of the porte cochere and around the skylights are systems of 15mm neon lighting (N1), which use about 5W per foot. Hotel Tower The lighting for the hotel tower façade is positioned on the roof of the second floor. There are two different types of luminaires. There are W metal halide spots (M14)

30 mounted twelve feet from the building exterior that use a lens with beam plus façade lighting optics. There are also 20 of the same fixture, but the lens only uses beam optics (M14A). Roof Gazebos Each gazebo includes 32 90W metal halide floods (M15). There are 8 mounted on the roof of each gazebo, 8 mounted on the deck below the roof, 8 mounted at the base of the gazebo glazing, and 8 mounted underneath the gazebo. 1 st Floor Exterior Façade The exterior walls of the performance hall and the video lottery are approximately flush with the fountain in front of the porte cochere. Suspended on these walls there are 8 vertical wall luminaires with 2 120W incandescent lamps per luminaire (F18A). Further from the porte cochere, recessed into the overhang of the exterior wall of the performance hall are 11 90W metal halide open reflector downlights (K1). Surface Reflectances Yellow-cream color exterior 50% Off white exterior 55% Design Criteria The porte cochere is as close to a grand Vegas-style casino entrance as Dover Downs gets. I feel that the theme should play on this, since the casino is thriving with plans for expansion. The porte cochere should reach out into the parking lot and on to the streets of Dover, DE and pull people in, people who can only wonder about what lies behind that breathtaking entrance. The style of the entrance should appeal to all ages, from grandparents to children. The fountain in front of the porte cochere should be a focal point of the lighting and should incorporate a creative design that has people stopping to admire it. Appearance of Space and Luminaires The appearance of this exterior space is very important because it gives all patrons their first taste of what is waiting inside. It should draw people towards it and make them want to take their time walking towards the entrance as they admire the beauty around them. Color Appearance The colors should be a major part of the entryway. They could even interact with patrons as they approach one of three entrances accessible from the porte cochere. Direct and Reflected Glare The last thing you want is a customer being blinded by light as they approach the building in which they plan on spending a substantial amount of money. Glare should be avoided as much as possible. Modeling of Faces or Objects As for all spaces in the building, the customers should be looking as good as possible. Peripheral Detection There should be adequate lighting in all exterior spaces to see in any given direction. There should be no worries or fear on behalf of poor lighting. Points of Interest Especially at night, lighting is the key to finding one s way from one place to the next. There are several entrances to Dover Downs along the

31 façade, three of which are under the porte cochere. Every entrance should be well lit, and since most of them lead somewhere specific, the destination should be clearly understandable while approaching the door. Shadows Shadows should for the most part be avoided. A large part of the building is a casino in which Dover Downs would love for its patrons to spend all night. When there is darkness a human tends to want to sleep more and stay up less. There is a direct correlation between this and the income of Dover Downs. Shadows could be used in places where patrons of the hotel are not wanted. Vertical Illuminance Should be 3fc or more, depending on the surface in question. Horizontal Illuminance This should be 5fc. However, every day and night several senior citizens come and go to and from Dover Downs. Therefore the illuminance should be higher then the prescribed values.

36 Evaluation Summary The porte cochere is usually the first part of the building that patrons see, as they come in from the parking lot they may be excited or not, but the porte cochere should get them excited and get them in the mood to gamble, or see a show, or watch a horse or car race. In my opinion the porte cochere in its present state does not accomplish this goal. There isn t necessarily anything wrong with the space, it is just boring. The space seems so promising as you walk up and see a nice fountain in front of three arches, lit from underneath the water. But as you make your way toward the entrance you notice some boring bollards lining the driveway and a few suspended decorative luminaires. There is some architectural cove lighting above, but it is nothing very special. With the current system there are no serious problems with glare, facial modeling, or shadows. There is more then enough vertical and horizontal illuminance also. The only problem is the lack of character of the lighting system. Dover Downs needs a lighting system so that when the senior citizens get off the bus with their bags full of quarters they will barely be able to contain themselves as they rush inside to find the closest slot machine or to pull up a stool at the newest, most cutting edge bar and lounge in the hotel industry.
