Yeah, i got their data for Hamilton and ran the numbers with it, and the results just seemed too good to be true. I checked the data to some degree with NASA, i'm still looking to cross-reference it...

Insulation at different latitudes

As i have been struggling to calculate the amount of sun to expect at a proposed building location at about 43 deg N, finally i made a chart. I still have my reservations about its absolute accuracy,...

Robert -
Power is a rate, but watts can also be a quantity. A machine might use up 100 watts in one hour, or in one minute. Knowing how many watts are involved doesn't tell you how much time it took...

Heat loss in watts, stored heat in joules - how to compare?

Hi all, i'm new :)
We are designing a passive solar house, and we have worked out how much heat we can store in its thermal mass, and how much solar energy passes through the glazing, both in...
