Window historic preservation issues
Our local historic preservation committee will not allow retrofits/replacement of so called historic windows – the aging, single-pane, wood frame with “wavy” glass. Some in the historic community claim that the existing windows can be retrofitted with films, weatherstripping, insulated shades or the like and match the performance of a high performance (e.g., energy star rated) window replacement. Unfortunately they don’t respond well to arguments based on the laws of physics and I’m asking if anyone has more specific “studies” – the historic types want studies – that show the quantify the benefits (not only energy savings, but improved durablility, reduced maintnenace, etc) of replacing historic windows vs. apply window film, etc. approach. Any help would be greatly appreciated.
