"I think that was part of his concern. Its a sealed combustion unit. So the infiltration that might be used for an ordinary fireplace is going to be off the chart. If its a new home with high end sealed combustion fireplace,…"
"The demarcation between the thermal hot and cold, appears to correspond with floor plate. If you look carefully you can see the framing members in the picture... three levels. The underside of the roof is very hot, it was in the shade…"
"South facing roof, looks like around noon.
1. Two possible AC units? One heating, one cooling?
2. Nice sunny summer day, clothes line empty - the dryer is being used in the house? On a nice summer day…"
"When you model, add a small additional area -- say less than 10 sq inch of for possible air leaks...(that should be real high)... be safe and model the fireplace at 60%... efficient. It really should be used just occasionally not…"
"The key is that this is the bathroom. Occupancy is not constant. It is more likely used in the morning and late afternoon. If the house is in a cooling dominated zone - the heat on all the time adds to the cooling load. For…"
I am an electrical engineer, creating sensors for data collection and "possibly internet of things"; I do believe many people, promoters and companies are going over board. That came up multiple times at last…"
"The observation about rot is important. I agree.
One of my complaints with some of the proposed insulated vinyl sidings - is the suggest simply putting it over the top of the existing siding. I believe BSC and one of the national…"

"Interesting, in that I had a "heated" discussion at the Seattle Home Show about a week ago with a distributor of a vinyl siding product that had insulation. While I personally would avoid the product, he did make a valid point…"
"My issue is that American Architecture is dumbed down to think you can be net-zero and not collect thermal energy, that's storing heat in winter, cold in summer at the right time of day or night."
Perhaps you need to visit the…"
"The energy that you can get from a wind turbine is proportional to the swept area. If you can get ten times more energy from a small wind turbine by changes to the generator - then you could get ten times more energy from those massive wind…"
"Tom, there is a significant efficiency loss when you look at the energy used with batteries on site by each windmill. I'd fallen into that trap before and it just doesn't pan out. In most cases you would be taking the AC…"
