→‎Air Conditioning
Calculating air conditioning is more complex and so the answers are more varied. The next table gives three sets of estimates to illustrate the issue.
Column A gives a series of BTU values derived from the buyenergyefficient.org web site [2]<ref>http://buyenergyefficient.org/</ref>.
Column B is based on an expert rule of thumb of 14 BTU per cubic foot, plus an extra 1000 BTU for good measure.
Column C uses the spreadsheet calculator.
