The question was how to translate- from design heat loss calculated by using ACCA manual J protocol to a yearly fuel usage. I outlined a crude way to do it. Is it perfect? Nope. There are a lot of caveats to…"
As a ballpark figure, take the design heat loss and divide by design temp difference, this gives you btu’s per °F per hour. Multiply this number by 24 hours (per day) and then multiply by heating degree days to get yearly …"
"Older buildings typically are 6-15 ACH50 worst I have personally tested was 17 ach50. The energy loss scales ~ linearly with ACH50 so If you go from 17 to 1.7, the heat loss from air leakage is reduced 10 fold.…"
