Wednesday Keynote — Why We Stopped Doing Deep Energy Retrofits

After completing many Deep Energy Retrofit projects (DERs) in the late 2000s early 2010s here in Massachusetts, our residential design-build remodeling company's approach to energy retrofit work has shifted towards lighter envelope improvements and a greater focus on getting homes off of on site fossil fuel consumption. While the DER approach was successful in substantially reducing energy consumption, among other improvements, it often came at a high cost both in terms of our clients investment and the embodied carbon impact of the work itself. In this presentation we will make the case for our current, more moderate approach to energy retrofit work, how we got here, and why we don't expect to be super-insulating many existing homes going forward.
