Greetings everyone, 

    I was told that I could get very basic heating loss calculations from TREAT. Besides the amount of fuel usage I cannot find where this basic heating calculation is in TREAT which I am certain it is staring at me right at the face! Could anyone be kind and point it out to me?

Thanks, 

    Luis

Luis, 

Click "selected reports, energy savings and use, design heating and cooling loads" then pick the improved package you want a load for. 

It's our experience that TREAT load calc is very close to Manual J - which tends to oversize equipment by 15-40% depending upon how well you intend to fix the home. (I have a client with a 6500 sf 1920's brick mansion that the load calc is 140,000 btu, and the house carries to 5° f with roughly 60,000 btu. We can prove this through Ecobee logging: http://bit.ly/4ecobeethermostats)

Our process is to downsize equipment until we get an undersized warning, then we know we are in the ballpark. If you don't get an undersized warning you are probably too big.
