2019-03-14 07:27:00 -0500 answered a question How is fraction latent, radiant, lost and convective decided for the heat gain from equipment? And why is the cooling energy higher when convective gain is 1, as compared to when the radiant gain is 1?

One reason might be that some of the radiant gains are being lost from the building. Since radiant gains are distributed
