"The carbon intensity of electricity use (lbs. of CO2/MWh) varies a lot from region to region. For instance, the grid in the Midwest has about twice the carbon intensity of the West Coast grid, due to more of the electricity being generated by coal…"
For too long there has been relatively little EE focus on multifamily, but some new programs have recently started. This group gives us a venue to share our experiences on cost effective audit & retrofit strategies and analysis tool needs.See More

"In the final animation, what's "CPM" stand for? Possible typo for CFM? Back when the Lennox Complete Heat and the early Polaris systems were on the market, a few contractors I talked to reported bad experiences. I heard…"
Linda Wigington distinguished between deep retrofits & deep energy reductions, thus expanding the range of strategies & tactics from which we might propose when engaging with people, the ones who choose.See More
"Can't tell you anything about boilers, but I could look up measured data for my own ECM furnace if that helps. If memory serves it was on the order of 10 watts total. I believe Scott Pigg of the Energy Center of Wisconsin has data for furnaces,…"
"This type of work is nearly useless in terms of gathering data about energy use. It may, however, be used to "enroll" people in trying to do something. VERY discouraging that this sort of thing is still happening."
Thought you might be interested in this news story. I know aerial thermography has been used many places, including London, but do you have an opinion on projects like this?
