What effect does the daily range have on heat gain?
A) Areas with a high daily range experience higher temperatures, so the cooling HTMs are higher. B) Areas with a high daily range generally do not require any cooling. C) Areas with a high daily range generally require equipment with more latent cooling capacity.
