Concentration is my motto. First honesty, then industry, then concentration.
Figure 1: HVAC Load for 17 People.
I was reading an article about HVAC (Heating, Ventilation, and Air Conditioning) calculations in the Journal of Light Construction that had a quote I found interesting. It said that
… 17 extra occupants added more than a half ton of cooling load.
Figure 1 shows how to prove this statement assuming that the average person burns 2000 kilocalories a day, which is probably a low number. This problem is all about unit conversion: kilocalories, BTUs, tons of cooling, etc. You might wonder why an electrical engineer would worry about these sorts of things. Unfortunately, I frequently have to specify the cooling capacity required for the electronics that I put into rooms.
