A spreadsheet

A spreadsheet was created that used these assumptions to calculate the costs associated with fan energy, cooling energy, and heating energy over a year using 5°F bin weather data. The weather data was filtered to only the number of hours in each temperature bin within the 6am to 10pm hours of operation. The annual energy costs were tabulated over the range of available transfer air percentages. Low transfer air percentages represent higher amounts outside makeup air that must be conditioned. High transfer air represents lower amounts of outside makeup air.
