Approaches to 30% Energy Savings at the Community Scale in the Hot-Humid Climate

Description

The Building America Partnership for Improved Residential Construction, formerly the Building America Industrialized Housing Partnership, has worked with several community-scale builders within the hot-humid climate zone to improve performance of production-, or community-scale, housing. Tommy Williams Homes (Gainesville, Florida), LifeStyle Homes (Melbourne, Florida), and Habitat for Humanity (various locations, Florida) have all been continuous partners of the Building America Program. The activities of these partners, described in this report, achieved the Building America goal of 30% whole-house source energy savings using packages adopted at the community scale. For new homes, the reference case is the B10 Benchmark, aligned with 2009 building codes.

Approaches to 30 Energy Savings at the Community Scale in the Hot-Humid Climate PDF This report describes how these goals were achieved in production-scale homes that were built cost effectively at the community scale and modeled to reduce whole-house energy use by 30% or more in the hot-humid climate region. Key aspects of this research include determining how to evolve existing energy efficiency packages to produce replicable target savings, identifying builders’ technical assistance needs for implementation and working with them to create sustainable quality assurance mechanisms, and documenting commercial viability through neutral cost analysis and market acceptance. This report documents barriers that builders overcame and the approaches they implemented to accomplish Building America Program goals that have not already been described in previous reports.
