FEDERAL FACILITY ASSESSMENT GUIDE Building Envelope Site Assessment Guidance General Lighting Assessment Procedure: Record light levels (ft candle) in various spaces using a hand held light meter Office light levels should be taken at desk level Hallway and restroom measurements should be taken at 4 ft 6 ft height – Record a min, max and average level for each space Record night time and daytime light levels within the space (Note: Make sure the lighting system can meet night time illuminance requirements when reducing LPD and light levels) When recording light levels next to windows, make sure to take a set of measurements away from the window as well Count lamps/ballasts in each room Count fixtures, lamps, and ballasts (Fixture counts can also be approximated from electrical drawings) Calculate the space area and calculate Watts/ft2 for each space type Record fixture type (i.e. recessed, recessed vented, indirect/direct, etc.) down lamp data and ballast data Look up ballast specifications on the internet Record lamp type, lamp color temperature (Kelvin), lamp wattage Site Assessment Tools: Use a light meter to record light levels, a roller wheel to measure space dimensions, and a tape measure to measure floor to window height. 50% Energy Savings over ASHRAE 90.1- 2004 FEDERAL FACILITY ASSESSMENT GUIDE Building Envelope Checklist Install Additional Insulation in Exterior Walls Adding insulation to exterior walls can reduce the heat gain or loss through the building envelope and save energy on maintaining comfortable conditions inside of the building. EIFS can be used for exterior insulation. Loose-fill can be used for enclosed existing wall, and hard to reach places. Rigid fibrous insulation is good for ducts in unconditioned spaces or other places requiring insulation that can withstand high temperatures. Sprayed foam and foamed-in-place insulation can be used in enclosed existing wall. Energy savings can be modeled in eQUEST. Seal Areas of Infiltration in Exterior Walls Using caulk or weather-stripping to seal areas of infiltration can reduce the amount of unconditioned air that enters the building, and save significant amounts of energy. Energy savings can be modeled in eQUEST. Fix Rain Leaks in Exterior Walls Rain leaks are indications of improper installation of siding material, poor-quality flashing, and weather-stripping or caulking around exterior joints. This can cause a drainage-plane within the wall system f the building and significantly damage the building envelope. Install Solar Shading Features on South-Facing Facades
