Heat load (BTU) = Length (m) x Width (m) x Height (m) x 141. So, for a room measuring 5m x 4m x 3m = 60 > x 141 = 8,460 BTU. (For measurements in feet, the formula becomes: Heat load (BTU) = Length (m) x Width (m) x Height (m) x 4)
Managers can use a rough estimate of 600 Btu per person when assessing the cooling load for a certain location. So, for a 400-square-foot workplace with limited occupancy, a rough estimate is 12,000 Btu, or 1 tonne of cooling.
In reality, depending on its state of consciousness, the human body produces between 250 and 400 BTUs of power. In other words, the body generates less when it is sleeping. To put it another way, this is about enough electricity to keep a 75-watt light bulb running for a few hours (or four of the energy-efficient pigtail light bulbs).
