Seasoned practitioners tackle the difficulties of residential Deep Energy Retrofits. When an architect experienced with Net Zero and Deep Energy Retrofits (DERs) spends his own money on his house, things get tricky. Starting with a house that used 700 gallons of oil, Tom Hartman’s been working on it for fifteen years. Now it’s not quite super-insulated, pretty air tight, once haunted by flying squirrels, but now using almost no oil. With a young family whose financial priorities did not include a whole house renovation; this project is a case study of a DGR- damn good renovation. Outside Boston, David Foley and Paul Eldrenkamp ought to know better, but decide anyhow to attempt a DER on a 1928 home they thought WASN’T located in Historic Preservation District. This panel discussion will address the challenges – political, economic, and technical – of high performing renovations in existing housing stock.
