Canterbury NH library saves big with insulation upgrade – Concord Monitor

Rachel Baker is going to have to think of a new present for library staffers this holiday season.

“For Christmas I would always buy them sweaters… just to keep them warm,” said Baker, who has worked at Canterbury’s town library for 20 years, the last five as its director.

Holiday sweaters, ugly or otherwise, won’t be needed this year because the building, a converted cinderblock fire station, now has something that most buildings take for granted: insulation.

“When I say it had zero insulation, I mean zero. I have pictures!” said Baker. “You could see Mt. Kearsarge through my roof… There was no caulking around my windows, none.”

That problem was solved during a five-day session in April, when crews from Northeast Air Sealing of Concord crawled through the roof and otherwise gained access to fill leaky air spaces and, in industry parlance, tighten the building envelope.

“They did the ceiling, all the walls, around the windows. They did it without us having to move the books out — they were brilliant,” Baker said.

Elkins Public Library at 9 Center Road moved into the former fire station in 2004 as part of a town-wide municipal building project, but initial plans for radiant heating were dropped, leaving just a propane furnace. Patrons and staffers have shivered through winters ever since.

The roughly $20,000 cost of the improvements was mostly covered by NH Saves, a program funded by New Hampshire utilities using ratepayer money that supports a variety of energy efficiency work, with the help of a $7,210 energy efficiency incentive from Unitil. Baker said town resident Tom Flaco did the heavy lifting on getting the assistance.

The improvements are expected to lower the library’s annual energy usage by approximately 1,515 gallons of propane, saving around $4,500 a year.  

The arrival of cold weather means people will be able enjoy the library without having to put on fingerless gloves and break out the space heaters, but even during the heat of summer, Baker noticed an unexpected improvement.

“Acoustics was the biggest difference,” she said. The uninsulated cinderblock building had allowed outdoor noise to intrude even as it reflected indoor noise. “We didn’t notice that until it was gone — it was so much quieter.”

The director has an extra reason to enjoy the upgrade because she grew up in Canterbury where her father, Dale Caswell, was fire chief.

“I knew this building intimately. I spent my childhood in this firehouse,” she said. Seeing it take on a new life has been a treat: “It’s a gorgeous space. We have so much room here.”
