<br /> <br />THE PRESERVATION OF HISTORIC BUILDINGS Is GREEN I <br /> <br /> <br /> <br />Tristan Roberts, Environmental Building News, January 2007. <br /> <br /> <br />1. Every year, Americans generate 124 million tons of <br />debris from demolished buildings alone. - National Trust <br />for Historic Preservation <br />2. Older buildings on average are built with better quality <br />materials and longer lasting construction methods. <br />3. Historic buildings have "embodied energy:' <br />a. Energy has already been expended to create <br />materials. <br />b. Embodied energy may represent as much as 30% of <br />the total energy used to create, operate, and maintain <br />a building over its lifetime. - Environmental Building <br />News, January 2007. <br />materials and workmanship in existing historic <br />or impossible to recreate in <br /> <br /> <br />today's economy. <br /> <br /> <br />LEED certification process is not compatible with <br />historic preservation. False, LEED for new construction <br />awards up to 3 points for reuse of a building. In order to <br />gain all three points, it is necessary to reuse the building <br />shell and 50% of the building's non-structural interior. <br />2. Secretary of the Interior Standards are not compatible <br />with sustainable design practices. False, the Secretary of <br />the Interior Standards for National Register Buildings <br />allow for buildings to be evolving artifacts. An example is <br />adaptive reuse. <br /> <br />~ <br />JD'l <br /> <br />City Council and <br />Historic Preservation <br />Commission thank you, the <br />voters, for approving the <br />Historic Preservation Sales <br />Tax. <br />Proceeds from the new tax will be used as in- <br />centives to help maintain and retain our historic <br />resources in Old Town. <br /> <br /> <br />1. Historic buildings were often constructed with energy <br />saving design features, such as operable exterior double <br />hung and interior transom windows that are designed for <br />cross ventilation, high ceilings, ceiling fans, porches and <br />awnings, etc. In order to reduce energy usage, it is impor- <br />tant to maintain and use these features, or uncover them <br />if they have been covered by previous renovations. <br />2. In older homes, air infiltration may result in greater en- <br />ergy loss than lack of insulation. Prior to insulating your <br />home, take the following measures: <br />a. Insulate at window and door jambs, install weather- <br />stripping, repair trim, install thresholds at doors, and <br />caulk where needed at openings to stop infiltration. <br />b. Install dampers and draft stops in historic fireplaces. <br />c. Install dryer vent seals that open only when your <br />dryer is in use. <br /> <br /> <br />affect- <br /> <br />ing historic value of your home: <br />a. Install water saving plumbing fixtures. If your fau- <br />cets have historic value, then simply installing a faucet <br />aerator can help save water. <br />b. Use compact florescent bulbs in lieu of incandescent <br />bulbs in your light fixtures. <br />appliances (look for the En- <br />ergy Star rating). <br />d. Install ceiling and whole house fans to help cool the <br />house at night. <br />can be blown in from <br />small holes near the top of each stud cavity so that <br />historic plaster and/ or siding can be preserved. <br />f. Insulate the attic, basement and crawl space. 20% of <br />a homes energy costs is a result of heat loss in these <br />areas. - National Trust for Historic Preservation <br />g. Insulate duct work that is outside of the insulated <br />envelope of your home (for example, duct work that <br />runs in attics above the insulation). <br />h. Install a programmable thermostat. <br /> <br /> <br /> <br />
