- What minimum number of waste streams must be diverted for C&D Waste Management?
Divert at least 50% of the total C&D material, including at least three material streams
- When reducing total waste material for C&D Waste Management what is the maximum amount of waste allowed?
2.5 lbs / SF (12.2 kg / m2) of waste for the building’s floor area
- What does not qualify as material diverted from disposal for C&D Waste Management Planning?
Alternative daily cover (ACD) and land-clearing debris.
- What hazardous waste stream categories require safe collection, storage, and disposal?
Choose two of these three: Batteries, mercury-containing lamps, or electronic waste
- What two simulations are required for Daylighting, Option 1 Simulation?
sDA and ASE
- What is the threshold for an sDA simulation?
300 lux for 50% of the hours between 8 AM and 6 PM local time for a full calendar year
- What is the threshold for an ASE simulation?
1,000 lux of direct sunlight for more than 250 hours of the year between 8 AM and 6 PM local time for a full calendar year
- When do the daylight simulations for Option 2 Simulation: Illuminance calculations occur?
9 AM on the first equinox (March 21 or September 21) and 3 PM on the second equinox
- At what height should daylight measurements be taken?
30 inches (750 mm) above the finished floor for the default workplane height
