Ensure walls adjacent to unconditioned garages, attics, or crawlspaces are calculated with a modified
Controlled fresh air introduced mechanically via ERVs, HRVs, or makeup air units. The Governing Mathematics Behind the Spreadsheet
The heating load calculation can be performed using the following formulas:
For commercial spaces, the complexity multiplies. A robust 2021 sheet must handle:
