Energy Efficiency at 317 Main

In the Fall of 2015, 317 Main made the significant step of purchasing our historic 1850’s building on Main Street in Yarmouth. One of the factors considered in the purchase of our building was our commitment to wanting to model good stewardship and demonstrate how environmental sustainability and historic preservation can go hand in hand. The added benefit of the potential to save money in energy costs and reallocate that money into programming served as an added incentive to pursue grant funding to make energy efficiency upgrades.

Grants to Green Maine

Grants to Green MaineIn December 2015, 317 Main was fortunate to be awarded a $35,000 grant from Grants to Green Maine (a partnership between the Maine Community Foundation, Maine Development Foundation and Efficiency Maine) to help cover the cost of energy efficiency upgrades to our historic building. The grant required a 1:1 match, and we were able to raise the match through a grant from Horizon Foundation, Quimby Family Foundation, Efficiency Maine rebates, and our community of donors.

The energy efficiency upgrades include supplementary insulation, air sealing, lighting upgrades, and installation of heat pumps – all of which were recommended in our energy audit. With these improvements, we expect to nearly eliminate our use of fuel oil. While our electricity usage is expected to slightly increase, the building envelope will be much tighter and our energy usage will be much more efficient. Ultimately, we aim to install solar panels at a future date to produce a portion of the energy needed on our property.

Annual Energy Savings Estimates from our Energy Audit

Insulation and Air Sealing:
570 Gallons of Heating Oil
= 5.8 metric tons of CO2
= $2,045 Saved

LED Light Bulbs:
12,672 kWh of Electricity
= 8.9 metric tons of CO2
= $1,900 Saved

Heat Pumps:
1,470 Gallons of Heating Oil
= 14.9 metric tons of CO2
= $5,262 Saved
