Carbon emissions
T/F Increased thermal comfort is a benefit of Daylighting?
False
LeadingGreen chooses to gut an existing building in a historic district, thus gaining points in which 2 LEED credits?
High Priority Sites & Building Reuse
In the Indoor Water Use Reduction prerequisite and credit, what is the baseline case compared to?
The design case installed in the building
(The baseline case is compared to the design case installed in the building, in order to find the percentage reduction in indoor water use. Design case versus the baseline case as determined by the EPAct of 1992 is the correct answer.)
Commissioning is the process of verifying and documenting that a building and all of its systems and assemblies are planned, designed, installed, tested, operated, and maintained to meet the owner’s project requirements. What is its median payback for an existing building?
1.7 years
How many credit categories does the LEED BD+C rating systems have?
8
(Location and Transportation (LT); Sustainable Sites (SS); Water Efficiency (WE); Energy and Atmosphere (EA); Materials and Resources (MR); Indoor Environmental Quality (EQ); Innovation (IN); and Regional Priority (RP). Even though it has 1 credit and 1 prerequisite, the Integrative Process (IP) is not included as a credit category.)
T/F Installing building-level meters will help reduce the amount of potable water used for irrigation?
False
(Building-level meters will track the whole building’s water use but will not show whether the potable water used for irrigation is being reduced. Irrigation water use would have to be tracked separately which is addressed in the water-metering credit.)
