This project includes the historic restoration of an 1805 Meeting House
and construction of a social hall annex designed to complement the
elegant simplicity and durability of the Meeting House.
Prior to design, Re:Vision Architecture's due diligence included an
energy audit, structural analysis, and archaeological investigation of
the existing site and historic Meeting House building. This information
formed the basis for a master plan which Re:Vision Architecture then
Through a collaborative green design charrette process, the building
committee worked with Re:Vision Architecture to ensure the building
reflected their core values of simplicity and environmental stewardship.
The end result was a project that received LEED® Platinum Certification
and has been recognized as a Zero-Net Energy building by the Northeast
Sustainable Energy Association.
Spaces within the newly constructed multi-functional annex include a
large social hall, catering kitchen, archival display, bathrooms, and
community meeting rooms. The newly constructed annex sits adjacent the
historic meeting house, but through careful design acts as a backdrop to
the rich context that the original building offers. In the social hall,
south facing windows allow for passive heating while clerestory windows
allow for passive cooling. A 12 kW photovoltaic array provides 150% of
the new buildings energy needs leaving a surplus for the remainder of
the complex. A year after occupancy, both the historic meeting house and
new annex use only a lightbulb's worth of energy more than they
generate. The project's alternative energy achievements lie in its
closed-loop geothermal system, photovoltaic array, and use of passive
solar and superior daylighting and insulation strategies. A 2,000 gallon
cistern reuses rainwater for flushing toilets and watering gardens,
while 100% of excess stormwater is filtrated on-site through
low-maintenance vegetated swales.
As green buildings go this project is the cream of the crop, but what is
most exciting is that the cost to build such a high performance building
was comparable to a typical building of this quality. Also of importance
in the success of this project was the contractor's knowledge of
sustainability. Boss Enterprises worked with the architect from the
beginning of the project to determine the most cost effective
sustainable solutions and at the end of the project handed over a
beautifully designed building that was built to endure.
