Testing the Performance of Historic Windows in a Cold Climate (1997-16)

A study was undertaken to determine the feasibility of renovating and upgrading an original condition window to the extent that its thermal performance would be equivalent to a window using replacement sash or window inserts. The study was funded by the State of Vermont Division for Historic Preservation based on a grant received from the National Center for Preservation Technology and Training of the U.S. National Park Service.

The Effects of Energy Efficiency Treatments on Historic Windows

This study of the effects of energy efficient treatments on historic windows was developed with
extensive help and support from many collaborators who contributed materials or worked
tirelessly for little or no compensation to achieve research results.

Research Report #1203: Measure Guideline – Wood Window Repair, Rehabilitation, and Replacement

There is a significant push for energy performance upgrades to existing homes. An important target is often the windows. Old single-glazed windows have such low thermal resistance that their effect on the overall thermal resistance of the walls can be staggering. Improving the performance of the window stock is therefore central to the goal of reducing the energy consumption of the existing building stock.

This measure guideline provides information and guidance about rehabilitating, retrofitting, and replacing wood window assemblies in residential construction.
