HI. I'm looking for a database that could help me assess the average energy use of a home (per square foot, probably), separated by climate zone (HVAC, not USDA). I do audits all over the country…Continue
"The most accurate way to accomplish this is to have 4 blower doors running at the same time, one for each apartment (maybe less, depending on the layout of the building). This is the only way to get individual infiltration numbers while eliminating…"
"HI. I am in the market for one exhaust fan flow meter and a pressure pan. Also a C-ring for the blower door. If you have any or all of those items for sale, please reply. Thanks. You can also email me at…"
"I'm not a big fan of TREAT. The biggest issue is that you have to true up the model to within 5% of the utility bill. A great idea except that, from my experience at least, the true up is just a random tweak here and there to make it…"

"Well, sort of... even Washington State has another chart that breaks down the climate zones into smaller chunks. That's because states often recognize a large difference between the north & south, or east portions of their state.…"
"No problem at all Ken. I'm not that familiar with the CEC climate zones, but they are different. My project was looking at the climate zones used by IECC (2006 specifically), which are 1-8 with an optional moisture description. The CEC zones…"
"Thanks for sharing this, Keith.
