Single Family Retrofit to Passive House EnerPHit Standards

When an experienced builder does a whole-house upgrade of their own home, you know it’s going to be done right. When that builder is Jesper Kruse, owner of Maine Passive House, you know remarkable energy efficiency will be the outcome. And when that house is the one Kruse himself built 20 years ago - the first house he ever built - well, you know it’s going to be an especially interesting adventure in single family retrofits. Kruse will explain why he decided to undertake this project. He’ll share step-by-step how he upgraded the envelope, from foundation to roof, and why he chose the new mechanical systems. He’ll offer data: the before and after utility costs, comparing project timeline anticipated versus actual, and the project costs. In this session, you’ll gain practical know-how for retrofits and understand how EnerPHit standards can guide and inspire builders toward passive house results.
