Which statement correctly describes the VT requirements and height threshold for Daylight Glass and Vision Glass?

• A. Daylight Glass = VT 60%+ and located above 2.1 m; Vision Glass = VT 50%+ located below 2.1 m
• B. Daylight Glass = VT 60%+; located below 2.1 m; Vision Glass = VT 50%+ located above 2.1 m
• C. Daylight Glass = VT 60%+; located above 3 m; Vision Glass = VT 50%+ located below 2.1 m
• D. Daylight Glass = VT 50%+; located above 2.1 m; Vision Glass = VT 50%+ located below 2.1 m

Answer: (A)

This item tests how Visible Transmittance (VT) and height thresholds separate Daylight Glass from Vision Glass in WELL daylight and views. Daylight Glass is meant to maximize daylight penetration while preserving privacy, so it uses a higher VT (60% or more) and is placed above 2.1 meters from the floor. Vision Glass provides exterior views at eye level, so it is located below 2.1 meters and uses a VT of 50% or more to balance visibility with glare and energy concerns. The pairing described in the statement—Daylight Glass with VT 60%+ above 2.1 m, and Vision Glass with VT 50%+ below 2.1 m—matches this approach. The other options mix up the VT values or the height threshold, which is why they don’t fit.
