Debunking Preservation Myths

Historic properties enrich our cities and capture our history. Don’t let myths about extra costs and over-regulation outweigh the benefits of undertaking your historic project! Historic buildings can’t be sustainable. FALSE. Several well-known historic buildings have been renovated to meet LEED standards. The U.S. Green Building Council recognizes historic buildings “represent significant embodied energy and cultural value”. LEED offers credits for the preservation or adaptive reuse of historic materials and features. New technologies and products make it possible to integrate sustainable solutions that improve the performance of a historic property. The Secretary of the Interior’s Standards for Rehabilitation include special Guidelines on Sustainability. Work with a historic architect to determine if any of the following modifications could improve building performance without permanently damaging historic materials: Windows | Restore windows by replacing putty or weather-stripping to create an air-tight window opening. Interior Storm Window | Installing interior storm windows can nearly double the window’s insulating value. A compression fit assembly can be installed without any additional hardware or holes in the historic frame. Insulation | Historic buildings may not have any insulation. Blown-In insulation products can be installed into walls through small holes or attic access to improve energy performance. HVAC | After testing the existing system for efficiency, a new HVAC system can be installed as necessary within the replacement cycle. High velocity air ducts have a slim profile and can be retrofit into existing walls to avoid visible ductwork or additional soffits. Restoration | Inherently sustainable features, like skylights and operable windows, naturally improve occupant comfort since they predate electricity. A designated historic building can’t be altered for ADA accessibility. FALSE. With the Americans with Disabilities Act of 1990, access to properties open to the public is a civil right. This doesn’t mean every property is required to install an […]
