That is also true but I didn't fancy complicating it overmuch. Something in the back of my head says the average human body emits around 100W of heat. That's one way busy venues can get really hot.

It's usually the sort of band where the singer wears a pork pie hat covering his shaved head when he arrives and who shouts a lot when he's on stage. Oh, and they only play their own stuff, never have CDs for sale and mutter a lot about 'the authenticity of the music'... -- William Black I've seen things you people wouldn't believe. Barbeques on fire by the chalets past the castle headland I watched the gift shops glitter in the darkness off the Newborough gate All these moments will be lost in time, like icecream on the beach Time for tea.

It seems to be standard practice for HVAC technicians to use occupant load in the calculations for ventilation, heating and cooling requirements for both commercial buildings and residences. http://hvac-tqmcintl.blogspot.com/2007/12/calculating-size-of-server-room-air.html suggests 400 BTU of cooling per occupant. Another reference recommends 15-20 CFM ventilation per occupant.

Another reference recommends > 15-20 CFM ventilation per occupant. 400 BTU/h is a tiny fraction over 100W, so yes, in the right ball park, esp given that other heat sources like lighting may need removal too.
