In May, 2010, the Library participated in the Maine Public Utilities Commission’s Efficiency Maine Business Energy Audit Program. A walk-through audit revealed several ways the Library could reduce its energy use and save money, including more efficient lighting, upgrading insulation, installing an on-demand hot water system, insulating hot water pipes, and providing better movement of air through the building. Recently, Board members Pete Chamberlain and Tom Withrow installed insulation on the pipes. We have had a consultant review our insulation needs and give us a quote. We are also getting quotes on electric hot water heaters that operate only when there is a demand (see photo), rather than using the furnace year round to heat a hot water coil in the boiler to provide for the small amount of hot water we use. We can save more than $480 a year in energy costs with just this one retrofit. We are looking into grants and low-interest energy loans to pay for the changes.
Here is what the “attic” of the Library looks like. Note that the insulation is uneven and patchy. Some areas are uncovered.
