Which LEED credit category specifically addresses a building's site selection, density, and access to public transportation?
Answer: Location & Transportation
The LEED Location & Transportation category rewards projects for smart location choices, including proximity to transit, walkability, and avoiding sensitive land.
A building commissioning process is intended to:
Answer: Verify that installed systems perform according to the owner's project requirements
Commissioning is a quality assurance process that verifies and documents that all building systems (HVAC, lighting, plumbing) are installed, calibrated, and performing as designed.
What is the purpose of a blower door test in building performance assessment?
Answer: Quantifying the airtightness of the building envelope
A blower door test depressurizes the building and measures how much air infiltrates through the envelope, expressed as ACH50 (air changes per hour at 50 Pascals of pressure).
Which insulation material has the highest R-value per inch and is commonly used in applications where space is limited?
Answer: Closed-cell spray polyurethane foam (SPF)
Closed-cell spray polyurethane foam provides approximately R-6 to R-7 per inch, the highest R-value per inch of common insulation materials, and also acts as an air and vapor barrier.
In sustainable building design, 'daylighting' primarily refers to:
Answer: Using natural light through windows, skylights, and light shelves to reduce electric lighting loads
Daylighting is the intentional use of natural light via windows, skylights, clerestories, and light shelves to illuminate building interiors, reducing dependence on artificial lighting.
Which material property makes rammed earth and concrete effective as thermal mass in passive solar buildings?
Answer: High heat capacity and slow heat release
Thermal mass materials like concrete and rammed earth have high heat capacity, absorbing solar energy during the day and slowly releasing it at night, moderating indoor temperature swings.
