General Lamp and Ballast Information The information listed below was provided by the Project Manual for this project. Specific luminaires, lamps and ballasts were not specified, but there were general requirements that all equipment had to meet. Fluorescent Ballasts All T8 and/or long compact fluorescent lamps should use solid state electronic ballasts that are also programmed rapid start. The ballast should have a total harmonic distortion limited to 10% and the output frequency shall not be between 30 and 42 khz. For normal light levels, fluorescent T8 ballasts must have a ballast factor of 88% or greater and long compact fluorescent ballasts must have a ballast factor of 96% or higher. All T5 fluorescent lamps should use solid state electronic ballasts that are also programmed rapid start. The ballast should have a total harmonic distortion limited to 10% and the output frequency shall not be between 30 and 42 khz. For normal light levels, ballasts must have a ballast factor of 98% or higher. Fixtures with low wattage (5-42 W) compact fluorescent lamps should use ballasts with a high power factor. Fixtures with 4-pin compact fluorescent lamps should use solid state electronic ballasts with THD between 30 and 42 khz. HID Ballasts All metal halide fixtures should be furnished with peak lead constant wattage autotransformer type ballasts with a minimum operating power of 90%. The ballast should be pulse start.

Dining Rooms The dining area of Redifer Commons is divided into many subspaces. The spaces included in the dining area are as follows: 2 open eating and study areas, a buffet style dining room that is sectioned off by itself, the Mongolian Grill, the main serving prep areas behind the cafeteria style counters, and the Marche. These areas are further described below. Dining Room 103 Tasks: The main tasks taking place in this space are eating, studying, and socializing. The written tasks include pencils, generally #2, and pen. The tasks being read will most likely be handouts, notebooks, notebook paper, magazines, and textbooks. There are also two TVs in the space, so students have the opportunity to watch them as well. Objects of interest: There are numerous windows surrounding this space since the room lies within 2 exterior walls. The windows are important since they provide daylight into the space. These windows are composed of 1 double-insulation glass glazing. The first ¼ is the thick clear exterior, then a ½ air space and finally a ¼ clear low E tempered glass on the interior.

Dining Room 117 Tasks: The main tasks taking place in this space are eating, studying, socializing, and circulation. The written tasks include pencils, generally #2, and pen. The tasks being read will most likely be handouts, notebooks, notebook paper, magazines, and textbooks. The main stairwell spills into this large dining room, therefore people must walk through this space to get to the cafeteria style kiosks to buy their food. There are also TVs in the low ceiling areas of the dining room. Objects of interest: This dining room has three sections, two with a single story ceiling heights which are on the left and right side of a double story ceiling height area. The double story ceiling height section uses clearstory windows to allow daylight into the space, while the single story section uses large windows on the exterior walls. The windows were not designed for daylight integration, but were added as an architectural detail. This architectural detail was inspired by the appearance of a cruise ship. The windows are composed of 1 doubleinsulation glass glazing. The first ¼ is the thick clear exterior, then a ½ air space and finally a ¼ clear low E tempered glass on the interior. A section of this space is shown below. When you are standing in the double height section of the dining room you are able to see the second floor corridor and offices through interior windows. The glass used here is ¼ tempered clear glass.

A La Board Dining Tasks: The main tasks taking place in this space are eating, socializing, watching TV, serving food, and retrieving food. This is a buffet style area of the dining room, so students are required to walk around the space, see what is available to them, and decide which type of food they would like to enjoy. The employees here are required to keep the food stocked and fresh in the buffet. Objects of interest: There are windows on one exterior wall. These are small windows compared to the windows in the other dining areas, and do not provide much daylight into the space. These windows are composed of 1 double-insulation glass glazing. The first ¼ is the thick clear exterior, then a ½ air space and finally a ¼ clear low E tempered glass on the interior. The two main objects of interest of the a la board dining space are the centrally located and rear buffet serving areas.

Mongolian Grill Tasks: This is both a food preparation area and a small seating area. The customer waits in line and when being served, is asked what they would like in their noodle meal. The customer then looks at the fresh array of ingredients and chooses what they would like. After their meal is prepared behind the counter, the customer retrieves the food and pays the cashier at the register. The cashier s main task is using the register and its screen, and to collect money and give proper change. Objects of interest: The sign for Hot Steel & Noodles and the Mongolian Grill should be very obvious and stick out of the surroundings. The ingredient selections should also be easily seen.

Kitchen Tasks: This is the area where all the food for the kiosks is initially prepared. The cooks need to be able to read the recipes, if necessary, and complete all tasks to cook the food. These tasks include cleaning the food, cutting, seasoning, mixing etc. There are also large coolers which hold refrigerated and frozen items, so the employees in the kitchen need to be able to accurately retrieve items from these coolers. Dishes are washed in the dishwashing section of the kitchen. Objects of interest: The countertops are the main area of the kitchen where all of the food preparation will occur. Besides that, this is a very general area used for cooking. Walls: Existing 8 CMU (Assume ρ=50%) Ceilings: Existing Acoustic Ceiling Tile Armstrong World Industries: www.armstrong.com ρ=85%.

Louie s Tasks: This is the convenience store of the commons where customers can buy food or drinks on the go. The customers will have to be able to read the packaging to figure out what they would like to eat or drink. There will also be conversation that occurs in this space, along with someone who must use the cash register and screen to check people out, take their money, and give them change. Objects of interest: The refrigerators and shelves that house the food are the main interest areas. Where you check out is also equally important, but is very hard to miss since it is in the front of the space. This space also has a very high domed ceiling which is a very important architectural feature.

Exterior Walkway Lighting Tasks: The exterior lighting is used the light the walkways so students (or whomever else for that matter) can get in and around the common area. There are some tables located outside for students to read, write or socialize. The written tasks include pencils, generally #2, and pen. The tasks being read will most likely be handouts, notebooks, notebook paper, magazines, and textbooks. Objects of Interest: The entrances into the commons are the main objectives here for the existing lighting design. Walkways and Stairs: Precast Portland cement Concrete Façade: Although the façade is not an element that was concentrated on for this design, the exterior wall is constructed out of red face brick.

Design Criteria and Critiques Large Work Space: Dining Room Appearance and Themes: Since this space is divided into many subspaces, it is important for the dining room to remain a single space, yet still leave room for each subspace to have their own unique style. The kiosks should separate themselves from the dining areas. It would also be nice if each dining space could have its own individuality. One dining area could have a more intimate feel, while the other has a more leisurely feel. The intimate area would have lower illuminance levels, accentuated with sparkle. On the other hand, the leisure space would use indirect, unobtrusive lighting applying moderate illuminance levels. The kiosks could keep their individuality by accentuating the color scheme s used and highlighting each sign independently. CRI: Lamps with a color rendering index of 80% or higher should be used because of the variety of bright colors used in the spaces CCT: Lamps with a color temperature of 3500-4000K should be implemented because of the rich color scheme. Uniform Workplane Illumination: This is important for students studying in the dining spaces. The high and low ceiling areas should also stay consistent. Direct and Reflected Glare: The last thing you want to see when glancing across this large open space is luminaires in the distance glaring directly into your eyes. Low luminaire luminance and luminaire shielding or lensing will avoid this problem. This is also an issue for those studying in the dining area. The paper tasks are usually notebooks, magazines or textbooks, all of which usually have a high reflectance. A highly reflective surface has the tendency of causing reflected glare back into the student s faces. Reflected glare off of the TVs and the cash register screens could also be a problem. Finally, reflected glare could also be an issue for the employees working behind the counters. Some of the countertops are aluminum, and since aluminum has a high reflectance, the luminaires reflection could possibly be directed straight into a worker s eye. Indirect Lighting: This type of lighting should be kept to a minimum where ceiling heights are low. This will increase the effective ceiling cavity potentially making the cavity appear larger. CRI: Lamps with a color rendering index of 80% or higher should be used because of the variety of bright colors used in the spaces. This is also important for fresh foods served such as salads, hoagies and fresh veggies at the Mongolian Grill. CCT: Lamps with a color temperature of 3500-4000K should be implemented because of the rich color scheme. Appearance of s: The luminaires should compliment the architecture of the space. The main dining room s design was inspired by the appearance of a cruise ship. This could be a very interesting architectural feature to emphasize. The luminaires in all the dining areas should remain fairly constant since they are joining in some way and are considered a single space. Bright and Exciting Light: This type of light keeps the brain stimulated and motivated. Since this is an area that can be used for studying this is particularly important. Accentuating Existing Color Scheme: The existing color theme is very vivid, so the lighting should enhance this property. 47
Highlights: The kiosk areas and the accompanying signs should have special attention drawn to them. The luminance levels of the signs and the kiosk counters should be greater than the dining rooms to make them really stick out. This will leave no questions as to where food should be purchased. The highlights will also help the customer clearly see the details of the food being served. Inviting: The commons should be a space that people like to go to relax, eat and socialize. The more inviting the space, the more comfortable people will feel and the more customers will come in to buy food. Daylighting: There is a vast amount of daylight that enters this space during daytime hours. The architect informed me that daylight was not considered for the existing lighting design, but the large windows and clearstory windows leave potential opportunity for daylighting. The daylighting effects would ultimately depend on the orientation of the building and the directions that the windows face. Facial Modeling: When people go out to a public space they would like to appear as they intend. Every person that could come through the space should be considered. The cashier s and employees behind the kiosks are especially important since they are the ones serving the clientele. Control Flexibility: The dining area is a very large space and it may be necessary to close down one section of the dining space before another during non-meal times. Controls could also be used to create different lighting environments for each meal. The type of lighting for breakfast isn t necessarily comfortable for lunch or dinner. Lamp Ambient Temperature: Heat tends to be an issue when you are dealing with fresh, cool, or frozen foods. Lamps with a low ambient temperature should be implemented. Illuminance Levels: Levels in the food display areas should be twice as bright as the surroundings and are required by IESNA to have an illuminance of 50fc. The cashier areas are required by IESNA to have a vertical illuminance of 3fc and a horizontal illuminance of 30fc. The dining areas are required by IESNA to have a vertical illuminance of 3 fc and a horizontal illuminance of 30fc on the workplane. The food preparation areas are required by IESNA to have a horizontal illuminance of 50fc. Critique: The main dining room (117) is separated into two sections- a high ceiling and a low ceiling section. The lower section is much brighter than the higher section. Actually, the higher section felt a little too dark and somewhat uncomfortable for doing school work, but created an intimate dining atmosphere. The decorative and uplight fixtures did not produce the same light output as the indirect fixtures in the lower section. The lower section also has a white acoustic tile ceiling which provides a lot of reflected light from the indirect structures. This lighting is very comfortable to do school work. I think these two spaces should have illuminance levels more similar to make them feel like they are one space. The smaller dining area (103) is also very bright and creates a much less intimate feel than the high section of main dining room. The different types of furniture used for seating create an interesting space and add to the individuality of the space. The buffet has a feeling that resembles more of a restaurant mainly because of the decorative wall sconces and pendants chosen for the space. The separation from the rest of the dining room also helps to create this feeling. This space also has two ceiling heights. While the higher ceiling uses semi-indirect fixtures which create a very bright ceiling, the lower ceiling contains recessed downlights which create a more intimate feel and a darker ceiling. This is a very comfortable eating area. The illumination levels vary greatly throughout the different spaces. For the most part the levels were sufficient except for the higher section of the main dining room. 48
Special Purpose Space: Kitchen Appearance and Themes: This is a very clean, hygienic space and should be designed to be simplistic. Functional design is more important for this space as apposed to creative lighting design. Uniform Illuminance: This is important for both the workplane and the floor. Uniformity is important on the floor for thorough cleaning. Cleanliness is also an issue on the workplane, but uniformity is also critical for the tasks involved with cooking. Direct and Reflected Glare: Direct glare should be avoided when looking at the ceiling. Also, the aluminum countertop could cause some reflected glare to reach a workers eye. Lensed fixtures would solve these problems. Illuminance: Levels should be high where critical tasks such as cooking on hot surfaces and cutting are taking place. Shadows: These should be avoided on all surfaces, especially countertops, shelves and storage areas. Illuminance Levels: The workplane is required by IESNA to have a horizontal illuminance of 50fc. All vertical surfaces, such as shelves and cabinets are required by IESNA to have a vertical illuminance of 3 fc. Critique: The kitchen has a very functional design and by the calculations I conducted exceed the required illuminance levels required by IESNA. The excessive brightness does not seem offensive and is necessary for the tasks. 49
