WELL AP WELL-AP Exam - Topic 4 Question 31 Discussion

Posted by Pamela on Apr 08, 2025 at 07:48 AM

Which thermal comfort parameter can be controlled by the use of automatic window shades?

Suggested Answer: D

Automatic window shades can significantly influence the mean radiant temperature within a space by controlling the amount of solar radiation that enters. The mean radiant temperature is a measure of the warmth that one feels from the radiant heat exchange with surrounding surfaces. By adjusting window shades automatically based on the sun's position and intensity, the system can reduce overheating from solar gain, thereby maintaining a more comfortable and stable indoor thermal environment. This control helps in creating a space that aligns with the WELL Building Standard's focus on thermal comfort, ensuring that occupants are comfortable and productive.

I feel like relative humidity might be influenced too, but I don't see how shades would directly affect that.
CY

I'm a bit confused on this one. I know automatic window shades can affect thermal comfort, but I'm not sure which specific parameter they control. I'll have to carefully consider the options and try to eliminate the ones that don't seem right.

I'm pretty confident the answer is D - mean radiant temperature. Automatic window shades can help regulate the amount of radiant heat from the sun that enters the space, which would affect the mean radiant temperature.
MY

Okay, let me see. Automatic window shades would affect the amount of solar radiation entering the space, which could impact the mean radiant temperature. But I'm not sure if that's the correct answer here. I'll have to review my notes on thermal comfort parameters.
