Energy Efficient Housing Rehabs: A Building
Science Approach to Understanding What Works
We have learned a lot about how houses work – or more accurately don’t work - in the last twenty years. However we have done a poor
job getting this information out to the residential construction industry, in both new construction and existing houses. If you, or those you finance or
employ, are still focusing on replacement windows, caulking, and weatherstripping to reduce heating and cooling costs, you really should attend this short
course. Learn why employing a contractor skilled in “dense packing” insulation is so important, especially if your housing stock includes balloon framed or
story-and-a half houses.
By attending this session, participants will
1. Find out how sealing cracks and holes at the top of the house – between the conditioned
space and the attic – will not only reduce heating bills but will prevent frozen pipes in the crawl space or basement
2. Recognize that installing a high efficiency
furnace and leaving the water heater vented into the old chimney can be deadly
3.
Learn why insulation installed in homes often does not
perform as expected
