Heating and Cooling Load Calculations in Excel

[BIPVguy]

All,

I would kindly ask for an information please.

Does anybody know where a simple piece of HVAC load calculation software (in excel for example) for a single zone building could be downloaded from?
For example, something like Retscreen. Unfortunately, it does not calculate loads but energy consumption using heating degree day method. The software is needed for fast calculations with adequate degree of accuracy.

Any feedback is greatly appreciated.
Cheers

You could easily do a single zone by hand with the CLTD method. Could take less time that trying to figure out a spreadsheet.
