Historic windows are among the most important elements of a building. Simple repairs and routine maintenance coupled with storm windows make for energy efficiency that in most cases matches, if not exceeds, the efficiency of replacement windows. Workshops throughout the country have taught participants easy ways to care for historic windows as pictured above. Historic preservation can—and should—be an important component of any effort to promote sustainable development. The conservation and improvement of our existing built resources, including reuse of historic and older buildings, greening the existing building stock, and reinvestment in older and historic communities, is crucial to combating climate change.Author: Rebecca Williams, field representative, National Trust for Historic PreservationUpdated in 2021 by Molly Baker, manager HOPECrew, National Trust for Historic Preservation#windows#HOPECrew#preservationtrades#Sustainability#ClimateChange
