It is a known scientific fact that the radiant component of comfort is an important one. Twenty-six pages in the ASHRAE Fundamentals Handbook (Chapter 8) are dedicated to thermal comfort. There are 120 referenced works on human comfort as well. The ASHRAE chapter goes to great lengths to explain the thermal interaction of the human body and the environment. The information presented is not conjecture; it is highly respected and soundly proven fact. Human comfort is determined by an energy balance between the heat generated by the body and the rate at which it loses it to the environment.
