The future home for Kent and Kim Quirk, and for the Enfield Energy Emporium’s store and showroom. This webpage will be used to document the renovation. We have some lofty project goals for this renovation — and we have a limited budget, so trade-offs will be made along the way.

Here are the goals:

  • Zero Energy Building, ZEB: All the energy we need to run this house is provided by or offset by renewable resources.
  • Leadership in Energy and Environmental Design, LEED-H: LEED for homes is a rating system that rates projects in 5 areas: sustainable site development, water savings, energy efficiency, materials and resources selection, and indoor environmental quality.
  • No Combustion: We believe we don’t have to burn anything to keep this house warm in the harsh New England winters. No oil, gas or wood. No pilot flame. No carbon monoxide either.
  • Historical Preservation: This house was originally built in the late 1850’s. It is gutted on the inside, the windows and siding have been removed/replaced, but there are some good ‘bones’. We’d like to keep (or restore) some of the outside look to retain the character of the building and its era.

And here is the strategy to meet those goals:

  • Seal the envelope and super insulate the building from basement to attic. Murphy Cell-Tech has done the design and heat model to meet the ZEB goals. This project is a partially a renovation and partially a new construction project. We can’t change the orientation of the house or build a new foundation, and we are keeping the outside shell. But everything on the inside has been gutted so we have the opportunity to insulate as if it were new construction.
  • Thermal Storage Tank, by Thermal Storage Solutions. Think of this as a very large, well insulated, thermos in the ground. Unlike geo-thermal systems we not using the ground for its heat capacity, just as a place to put the thermos. The size of this tank, how many BTUs can be stored, for how long, and how quickly they can be retrieved in the winter are all part of the heating models for this house.
  • Evacuated solar tubes will provide the solar collection to fill the thermos with BTUs. The evacuated tube technology is great for New England since the vacuum around the heat collector helps insulate the heat from a very cold winter day. The thermos fills up all summer, and then gets drawn off in the winter to heat the house.
  • Circulating Air (like radiant floor heating, only with air). We will use an energy recovery whole-house ventilator to circulate warm air in the winter keeping the house at a constant temperature throughout. The water pump and circulators as well as the water ot air exchanger and ventilator have to meet very low energy requirements so we can offset all of our electrical use with solar photovolatic modules.
