The energy used to heat New England's houses contributes 36.4 million metric tons of carbon dioxide emissions, almost 20% of New England's total energy-related carbon dioxide emissions (U.S. EIA 2005a). Energy efficient renovations (EERs) can potentially make a significant dent on residential energy consumption and potentially greenhouse gas emissions. This thesis examines the observed barriers to home EERs and the potential solutions for their implementation in urban New England communities, such as Lowell, Massachusetts.;The primary research methods used in this thesis include a literature review and focus groups about EERs with residents from three different neighborhoods in Lowell, Massachusetts. Results of the focus groups revealed that air sealing (e.g. insulation) renovations were the most popular type of EER. Increasing energy efficiency and increasing home comfort were acknowledged as the two top drivers for EERs. Some of the most significant barriers to EERs included upfront costs, contractor issues, and disturbance to living conditions.;A mix of regulatory and non-regulatory methods to encourage EERs is recommended for urban New England communities based on the literature review and research in Lowell. Residential Energy Conservation Ordinances (RECOs) appear to be the most direct regulatory strategy for existing homes and can also help to overcome the renter-occupied housing barrier. The implementation of a local Green Building Program is recommended as a non-regulatory strategy to encourage home EERs.
