Mark Attard Operations Manager at Hammer Well custom homes is helping to lead the company towards a commitment to building exceptional custom homes following passive house principles. In that effort, Mark gained significant building science knowledge that he has applied in a complete retrofit of his own 1990 vintage home. Starting at 17 ACH50, mark improved the thermal envelope, air tightness, mechanical and ventilation systems in his house following building principals he and his colleges at Hammer Well are now taking to all their projects. Mark however has gotten to see the fruits of his labor because the neighborhood where his house is located ended up protecting downtown Louisville from the recent Boulder County Marshall Fire. One house burned in Mark’s neighborhood as firefighters defend the aera to ensure that the fire did not reach downtown Louisville. As you can imagine houses with air leakage in the 17 ACH50 range, All were smoke damaged. Mark’s house faired differently, and it’s story is the basis of this episode of the buildCAST. I can’t say I hope you enjoy this episode, but I do hope we listen well and learn a lesson of the byproduct of resiliency that can come from applied building science and better performing buildings.
