So if were to consider the buffer zone at half the temp gradient 26.5*5/9=14.7C 2.8*14.7=41.2wh*24=989wday*31 31kwh loss for January compared...

so 0.5*53=26.5btu/sqft/hr? 7.8wh*24=186wh still not right far cry from the 2k the metric method came up with wait * 10.76 = 83wh/sq meter thats...
you bring up some good points, the weight for example, in all honesty I havent yet really considered any kind of fancy window including tripples...
yes it is but something is not right, the way Corwin was doing it 1600 hdd * 0.5 U=600 btus loss, I need to look into this something is not right...
that is very different than my latest math
november through march is what concerns me 5132 hdd, now want there a way to figure heatloss based on hdd after all is a delta temperature...
looking at july arround 73-74F hdd evens with cdd so in theory a properly designed house should even up right arround there on it's own, this pos...

ok so lets start with some real numbers, I tried to look up the code requirement for conversation sake but came up empty, curently my thermostat...
funny definately not the bunch to do this, I doubt the coating does much for heatloss, so you can call this exercise for coated glass. I need to...
I was just going back and reading through and althou I am still not serious about expensive windows for the weight and cost factor I think I found...
good point, the sun rooms role is to provide some insulation for the livingspace at the cost of some solar radiation, so I guess depending on the...
