Deep energy retrofits are key to decarbonizing our building stock. They also allow us to salvage building materials, prolonging their life cycles and keeping them from the landfill. Examples below include single-family homes, multifamily buildings, and even a hotel in Spain. We'll be taking a few weeks off from programing for the holidays, but we'll be back in January with more great articles and videos.

See you in 2024!

Response to the NESEA BE Boston 2023 Wednesday Keynote, “Why we Stopped Doing Deep Energy Retrofits”

"Unless the commons are assigned a value, and every economic decision is inclusive of the cost of harm to said commons, 'cost benefit' is a one-sided fiction," Hindle writes. "In short Rachel and Brendan were applying a cost-benefit analysis for a micro-economic context to make a statement about our industry’s strategic responses to a crisis of the global commons known as the atmosphere.  The tool does not fit the task."
