    Lightbulb Humans radiate heat. Calculate air conditioning necessary for a party!

    Dear nerds,

    I'm hosting a party in a hot part of the country. I'm going to need air conditioning that factors in guests radiating heat, and I'd like your help calculating the set temperature difference to accommodate guests properly.

    [x attendees] x [100 kcal / hr, which is the average radiation of people at rest] = x100 kcal / hr of energy radiating into the room, nearly all dispersed in heat.

    What comes next to figuring out how to preset the thermostat?

    Set it [ @ 22 degrees] and forget it.

    One kcal of energy raises the temperature of 1 gram of water (which I think is a 1cm^3 by volume) by 1,000 degrees, by definition. So, you can do some crafty multiplications and divisions by the area of your house, the height of your floor (probably 10 feet), the "specific heat" of air, the number of people at the party, and the kcals of energy per hour given off per person.

    Just.. screw with the multiplication and division of numbers until the units work out; that's what chemistry teaches us to do. This will all give you the difference in temperature caused by your guests so that you can set your thermostat to account for it.

    The last step should be to 'impress' all of your friends by running through all of these boring calculations with them, preferably on a whiteboard. Then they'll all leave and you won't have to adjust the thermostat at all.

    Set from 64F to 68F, unless you are going to factor windows plus dozens of smaller items. Most large arenas and business buildings tend to set the temperature lower (people complain less when cooler then hot). Expect women in menopause to complain no matter what the temperature, tell them you will adjust the setting, do nothing, and they very often think you did something.

    Just go to your local grocery store or other places where large amounts of people gather and ask them what they set their thermostats at in the summer. Then take an average and there you go. You'll probably get AS good an approximation this way than if you were to calculate based on your specific needs. Especially if it's a big party at a big venue.

    Thermostats will automatically set maintain the set temperature regardless of the heat load or the outside temperature. There is no need to do any calculations.

    Some people just radiate heat more than others. Hot bitches.

    Wow... just wow.
    For all that we have done, as a civilization, as individuals, the universe is not stable, and nor is any single thing within it. Stars consume themselves, the universe itself rushes apart, and we ourselves are composed of matter in constant flux. Colonies of cells in temporary alliance, replicating and decaying and housed within, an incandescent cloud of electrical impulses. This is reality, this is self knowledge, and the perception of it will, of course, make you dizzy.
