Author decomposes temperature into two separate parts, air and radiant, to derive an operative temperature. This also explains why extended setbacks that allow the interior thermal mass to rise in temperature too much are a bad idea. He focuses on comfort, but in this time and circumstance he should be saying health. Speaking of which, since operative temperature is an average, comfort resulting from reducing air temperature is reduced by a factor of two.
Interestingly:
\"As a professor of architecture and building science, I believe todayâs byzantine building codes and rental rules could be greatly improved for comfort by regulating mean radiant temperature rather than air temperature. Vast sections of code could be jettisoned by requiring that interior surfaces, which are easy to measure with an inexpensive infrared thermometer, be kept within a comfort range above 60 F (15.6 C) and below 85 F (29.4 C).\"
Junk housing costs more to condition just to stay alive, and HVAC replacement schedule is accelerated.
