Passive House Building

We recognize the need for greater energy efficiency green building practices within the Boston construction industry. We want to do our part in reducing emissions and creating buildings that improve the health and well-being of those who inhabit them. So, we design and build according to passive house standards.

We also recognize the benefits that high performance and passive buildings provide. Not only are they better for us and for the environment, they also happen to be very cost-effective. Haycon is committed to creating spaces that provide a high quality of living at a reasonable cost.

"Another great project by Haycon. They keep advancing and improving their builds. Every step of the way, they learn and improve. They definitely don't use the phrase 'We've been doing it this way for 30 years."

- Kenneth Keifer of SIGA North America
