Preserving historic buildings is important work, but it has often met notable obstacles from an energy efficiency standpoint. Massachusetts happens to have a disproportionate number of historic buildings, which presents an issue for us at DOER: how can we make energy efficiency the standard statewide when so many buildings have to maintain their cultural and aesthetic history?
Architectural Heritage Foundation, a Boston-based non-profit that combines historic preservation and business economic development, partnered with two other regional organizations to propose a dynamic solution to this problem. They were awarded $625,000 from DOER’s federal stimulus-funded High Performance Buildings Grant program to implement Deep Energy Retrofits on three unique historic buildings, reducing their energy use by 50% and demonstrating a way for other historic buildings to cut their energy use.
I swung through Ipswich to see how the Architectural Heritage Foundation’s work on the Old House at Appleton Farms was going a few weeks ago, and it was an incredible thing to see. The building, which was rotting and literally falling over before work began, is now shaping up to be a beautiful new home for The Trustees of Reservation’s (TTOR) Center for Agriculture and the Environment. In addition to bringing the house up to code, the contractor is installing insulation on the outside, and blowing cellulose into the walls on the inside—doubling the insulating value of the walls and roof and eliminating any ‘bridges’ where the cold can get in. They’ve also repaired many windows and replaced irreparable ones with high efficiency models, balancing the need to be historically authentic and energy efficient. The house will be heated by a biomass boiler, and the hot water will come from solar heaters on the roof—eliminating most demand for fossil fuels.
Meanwhile, in Ashfield, the Trustees are busy on another old farmhouse on the Bullitt reservation. Bullitt, like Appleton, was also falling apart. But after getting similar treatment to Appleton Farms, the house is now so well insulated that when I visited (a chilly 42 degree November day), the entire house was comfortably warm—heated by the body heat of the four folks working on the house. There’s also an energy recovery ventilator in the basement to ensure proper air circulation without losing heat to the outside. The future occupants of the house, the Hilltown Land Trust and the Highland Communities Initiative, will rarely have to turn on the heat. When the Trustees install solar panels on a nearby barn next year, this house will use next to no electricity from the electric grid, and no fossil fuels – making it quite possibly the first zero net energy historic building in Massachusetts!
The Appleton and Bullitt projects will be some of the oldest energy efficient historical buildings in New England. In the end, however, the real value of these projects will be the example they set. We’ll keep you updated on the Appleton and Bullitt projects and a third project – the Lyman Estate in Waltham – when it begins. More information on the projects is available on TTOR’s website.
Dam Ice posted on Mar 12
You may have noticed many “falling ice” signs around town. Personally, I recently counted five of them on my way to the coffee shop. The icicles and falling ice are actually caused by ice dams, and the Building Science Corporation (BSC) and Massachusetts Department of …Continue Reading Dam Ice
Fish Need Clean Energy, Too posted on Feb 18
Running a fish farm is an intense operation, one that requires a lot of labor and a large amount of energy. Currently, the McLaughlin Hatchery uses a significant amount of oil to heat its facility. The facility is going to replace its oil furnace with a renewable energy heating system, a new high efficiency wood pellet boiler and pellet storage silo that will reduce greenhouse gas emissions by almost 92 percent, save an estimated $11,432 annually, and reduce annual oil use by more than 5,000 gallons.
Wood Pellets are the New Oil for Regional Schools Reducing Fuel Costs posted on Feb 12
Did you know that it is possible to heat buildings in the northeast using wood biomass, a renewable energy fuel? With nearly one-third of total energy costs going toward heating our buildings, it is no wonder that Massachusetts school districts are searching for cheaper and …Continue Reading Wood Pellets are the New Oil for Regional Schools Reducing Fuel Costs
