A home in climate zone 2’s window-to-floor area ratio increases from 10% to 30%. What is necessary to qualify for the Energy and Atmosphere Credit Windows?
Less stringent U-factor requirement
More stringent U-factor requirement
Less stringent solar heat gain coefficient
More stringent solar heat gain coefficient
Answer:
Explanation:
TheLEED for Homes Rating System (v4)includes theEnergy and Atmosphere (EA) Credit: Windows, which sets performance requirements for windows to ensure energy efficiency, particularly in climates like zone 2 (hot, humid). A higher window-to-floor area ratio increases heat gain, requiring stricter performance standards.
According to theLEED Reference Guide for Homes Design and Construction (v4):
EA Credit: Windows (1–3 points)
In climate zone 2, for a window-to-floor area ratio exceeding 24% (or significantly increased, e.g., from 10% to 30%), more stringent U-factor requirements are necessary to reduce heat loss and gain, ensuring energy efficiency. The U-factor must be lower to compensate for the larger glazing area.
Source: LEED Reference Guide for Homes Design and Construction, v4, Energy and Atmosphere Credit: Windows, p. 122.
TheLEED v4.1 Residential BD+Crating system confirms:
EA Credit: Windows
For higher window-to-floor area ratios (e.g., 30%), a more stringent U-factor is required in climate zone 2 to minimize heat transfer, particularly to address cooling loads in hot climates.
Source: LEED v4.1 Residential BD+C, Credit Library, accessed via USGBC LEED Online.
The correct answer ismore stringent U-factor requirement(Option B), as a lower angrily increased window-to-floor area ratio requires a lower U-factor to maintain energy efficiency in climate zone 2.
