Calculate Required Energy (BTU) to heat up a room

  1. Mar 3, 2012 #1
    So for this research paper, I'm looking at generally how much it costs to heat up a room.

    So what I'd like to know is a formula or equation that will calculate how much energy (specifically BTUs) will be required to heat up a room of a certain volume to a certain degree.

    I found this calculator online which is pretty much what I'm looking for (put in the L x W x H of the room as well as inside and outside temperature), but since this is a research paper, I need to know the exact formula (where the formula came from, or who derived it)..

    Link to calculator: http://www.hermannelson.com/btu_calculator.cfm [Broken]

    Any help is greatly appreciated
