Are Historic Windows Energy Efficient? (2017). By Scott Sidler
This article discusses the comparisons between replacement windows and historic double hung windows and includes testing completed by the Window Preservation Standards Collaborative showing different types of restoration and weatherstripping techniques and their relative effectiveness on the efficiency of historic wood windows.
Evaluating the Energy Performance of Window Retrofit and Replacement
Homeowners and design professionals seeking to upgrade the performance and efficiency of existing windows are faced with many choices—from simple, low cost, do-it-yourself solutions such as window films and weather stripping to replacing older windows with new ones that require investments costing tens of thousands of dollars. Often these decisions are made without a clear understanding of the range of options available, an evaluation of the ability of these options to provide energy and cost savings, or proper consideration for the historic character of the existing windows. This study builds on previous research and examines multiple window improvement options, comparing the relative energy, carbon, and cost savings of various choices across multiple climate regions. Results of this analysis demonstrate that a number of existing window retrofit strategies come very close to the energy performance of high-performance replacement windows at a fraction of the cost.

The replacement window industry says that single-pane wood windows cannot be energy efficient and must be replaced. The local historic district design guidelines say that historic windows must be retained, seemingly without regard to energy efficiency. The homeowner is caught in the middle without the facts. The truth is that windows (old or new) are never highly energy efficient when compared with other materials. Will triple-glazed, Low-e, argon gas-filled replacement windows decrease heat loss to a level below that which is allowed by a historic window? Chances are that it will. The big question, though, is whether the decrease will result in a cost savings that makes replacing the windows cost effective. In general, the answer is no. This paper will elaborate on this point.
