Single-family detached homes (non-manufactured) comprise 63% of American residences. Over 25% of electricity and 60% of natural gas consumed in these homes goes towards space heating and air conditioning. Systems that can reduce the HVAC-related energy use of these home will have a significant impact on overall residential energy use.
Attic spaces and their interfaces to living space contribute to household energy use through increased HVAC loads. Insulation and radiant barrier systems can be used to reduce the energy use associated with attic spaces. The purpose of this project is to evaluate the effectiveness of these attic insulation and thermal barrier systems for reducing HVAC system load. The effects of emissivity changes in radiant barriers due to dust fouling will also be investigated.
