Your High Performance Home Made Easy

John makes building science and green building easy to understand and execute.  His patience and guidance were very much appreciated in helping me implement a high level of energy efficiency into my self-built home.  His expertise saved me time and money in doing things correctly the first time.  I know I will call John for his help on my next project.

We rely on John’s ability to think through interrelated building systems and help specify the insulation, air sealing details, and equipment that helps make the homes we design comfortable and efficient.

Working with John to design the HVAC and solar power systems for my Boston home was actually so much fun. He is super bright and has a sound, practical approach to his work that delivers.  The fact that he designed and lives in his own Net-Zero Energy home gave us the confidence that he would guide us to achieve the same for ours. It's not easy to find a consultant who listens well, is easy to talk to, and provides a clear plan for your project's systems, but with John, that is exactly what you'll get.
