Chartier Sustainability Group provided consulting and energy auditing services for this gut renovation of a 120 year old single family townhouse.  To make the building airtight, high efficiency windows and closed cell spray foam were installed.  To lower operating costs, low-flow plumbing fixtures such as dual flush toilets were installed, along with high efficiency lighting, HVAC and domestic hot water equipment, including a 95% efficiency condensing boiler system.  To improve air quality, energy recovery ventilators were installed.  The new house was even designed to accommodate the future installation of a solar array to produce electricity and hot water.

The end result was a 70% reduction in gas consumption and 38% reduction in electricity consumption, an average monthly gas & electric bill of only $80 year round, and a healthier, more comfortable home.
