Site The site plan illustrates a center public space between the buildings where faculty and students can gather. This space is not really efficient because the space is not covered, ventilation is almost non-existent, and the water features that are supposed to cool the space is not working to plan. A-100

Floor Plan Conference rooms, which require few if any windows for light and views, need a great deal of cooling because of high internal heat gains from activities or equipment; they should be located on the north or east side of the building (Binggeli, 2010). In the Chapman Building, the auditorium is located in the northwest side of the building. A-200

Sections & Elevations The elevation shows how big or small windows are, indicating the heat gain inside the building. It also tells the materiality of the exterior walls and color. A-302

Sections & Elevations Light colors are used in the façade (white and gray). These color surfaces bounce off the heat back into the space preventing the heat absorption, like a dark surface would (Binggeli, 2010). A-308

Wall Assembly Rigid insulation comes in blocks, boards, and sheets. It is often applied to the outside of the building. It offers a barrier to radiant heat. Reflected insulation uses material of high reflectivity and low emissivity, such as aluminum foil in conjunction with dead-air space to reduce the transfer of the radiant heat (Binggeli, 2010). A-604

Roof Plan Roofs provide a barrier to excess summer solar radiation, especially in tropical weathers where the sun is directly overhead. The transmission of solar heat from the rood to the interior of a building can result in high ceiling temperatures. Surfaces that reflect most infrared (IR) rays heat up very little in the sun. High ceiling temperatures can be reduced with thermally resistant materials, which have a high thermal capacity, or ventilated spaces in the roof structure (Binggeli, 2010). A-200

Roof Details How much insulation is required depends on where you live and the expected temperature extremes. Insulation is identified and labeled according to its R-value. "R" is resistance to heat flow. Higher R-values provide greater insulation. For example, R-19 insulation provides 72% more insulating power than R-11 (Dulley, 2010). The easiest and most cost-effective way to insulate a building is to add insulation in the roof. The thickness of insulation determines its effectiveness. If there is less than R-19 (6 inches of fiber glass or rock wool or 5 inches of cellulose) you could probably benefit by adding more. Most U.S. homes should have between R-19 and R-49 insulation in the attic (Dulley, 2010). A-907 A-907

Ceiling & Roofing Details This roofing detail shows how the perforated suspended ceiling works in the special events room and the main building. A-211 A-211

Window Details Sealant: Thermal window treatments designed to seal out cold air need to be properly sealed at the top, bottom, and sides to prevent moist air from entering the space between the insulation and the glass, where it will condense against the cold window (Binggeli, 2010). A-716 A-717

Window Details Insulating shades stop up to 86 percent of the exterior heat gain (Binggeli, 2010). Glass has a low resistant to heat flow, so double-glazing with air trapped in thin layers between sheets of glass is used for a significant increase of thermal resistance (Binggeli, 2010).

Door Details We observed that doors have weather stripping along the outer edges of the doors. This prevents the ac from escaping and also prevents heat to enter the space.

Cooling Systems Flexible ducting is used to connect supply-air registers to the main ductwork to allow adjustments in the location of ceiling fixtures. Concealed ductwork permits more effective isolation from the noise and vibration of equipment and from the flow of air. Surfaces are less complicated to clean and less visible (Binggeli, 2010). Ducts should be insulated, and all joints and seams should be sealed for energy efficiency.

Air Handler The air handler receives the cold water from the cooling pump in picture A. The air handler in picture C, then pushes the cold air from the cold water supply in picture B and distributes the air throughout the floor. Most mechanical rooms are cooled with these systems to provide a comfortable space for employees to work in. Picture C Picture A Picture B

Air Quality • Career Services Building • The building had a scent of new furniture. • This is typically liked by user’s but this is actually not a good thing as this is produced from the off gassing of the new materials. These new materials should have a period of ventilation before or after installation and BEFORE users use the products.
