For over thirty years, the Preservation Trust of Vermont has been helping communities save and reuse their historic places. Every now and then, though, it is helpful to take a step back and look at why we are so passionate about our work.
Colleagues from the Preservation Trust, the Division for Historic Preservation, and Jeremiah Parker Restoration have been working collaboratively with Efficiency Vermont to better understand energy efficiency in relation to historic buildings.
We’re in full agreement on where to start to realize energy savings and improved building performance, including:
- addressing moisture problems
- installing efficient furnaces, appliances and light bulbs effectively
- sealing air leaks with an awareness of combustion safety effectively insulating attics and foundations weatherizing historic windows and installing high quality storm windows
- insulating walls: Because of the potential serious moisture damage risk to historic structures, consider wall insulation after evaluating the other improvements, taking into account construction type, expected costs and savings, materials and existing or potential moisture problems. Make sure that you or a potential contractor has a professional understanding of both interior moisture and exterior water management strategies to manage any risk to the building.
The work described in the bullets above will realize a substantial return on investment for any building. As with any weatherization improvements, an understanding of existing and potential moisture issues or effects on combustion appliances is very important.
