Applications of sustainable technology to retrofits in urban areas

Abstract

Energy Losses from old buildings comprise a significant percentage of the total residential energy consumption in the United States. Retrofitting buildings for conservation can greatly decrease the present energy demand and help prevent an eventual depletion of the world's natural resources. This investigation analyzes energy efficient measures applicable to retrofits in residential buildings in New England. The project estimates the likely performance of the latest sustainable technology and rates them according to cost-effectiveness for an average homeowner. Various retrofit measures and applications of sustainable technology are assessed according to relative importance and net savings. Improvements include a building envelope upgrade, an installation of a ground source heat pump and renewable energy systems. The analysis determines the energy savings relative to two base case models: a Cambridge Code and 1920s standard. The retrofit measures are analyzed at present and future energy rates.
