Efficient Multifamily Homes In A Hot-Humid Climate By Atlantic Housing Partners, Florida Solar Energy Center, David Chasar

FSEC Energy Research Center®

With assistance from the Florida Solar Energy Center (FSEC) and its Building America Partnership for Improved Residential Construction (BA-PIRC), Atlantic Housing Partners (AHP)has implemented a high performance, systems-engineered package of measures in the new construction multifamily housing sector in the hot-humid climate zone. This report demonstrates how the initiative achieves Building America (BA) goals of 30%-50% energy savings. In addition, the report discusses the role of utility allowance calculations, used as part of the low-income housing tax credit process, to value those energy savings.

Results of energy modeling are presented to demonstrate that the specification package achieves 40% energy savings …

Approaches To 30% Energy Savings At The Community Scale In The Hot-Humid Climate, Florida Solar Energy Center, Stephanie Thomas-Rees

FSEC Energy Research Center®

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 …

Energy Retrofit Field Study And Best Practices In A Hot-Humid Climate, Florida Solar Energy Center, Janet Mcilvaine

FSEC Energy Research Center®

In the U.S. Census Bureau's Southern region, housing starts ranged from 4.6 to 5.9 million per decade from the 1970s through the 2000s, nearly twice as many as any other region across all decades. The potential for energy savings in these homes is vast, perhaps our most available untapped resource for reducing energy needs. This study was conducted in central Florida, which forms part of the Census Bureau's Southern region. It examines efficiency retrofit opportunities, typical renovation practices, and pathways for achieving U.S. Department of Energy (DOE) goals for existing homes in that region.

Short-Term Test Results: Transitional Housing Energy Efficiency Retrofit In The Hot-Humid Climate, Florida Solar Energy Center, Karen Sutherland

This project evaluates the renovation of a 5,800-ft², multiuse facility located in St. Petersburg, on the west coast of central Florida, in the hot-humid climate. An optimal package of retrofit measures was designed to deliver 30%-40% annual energy cost savings for this building with annual utility bills exceeding $16,000 and high base load consumption. Researchers projected energy cost savings for potential retrofit measures based on pre-retrofit findings and disaggregated, weather-normalized utility data. A cost-benefit analysis was conducted for the seven retrofit measures implemented; adding attic insulation and sealing soffits, tinting windows, improving whole-building airtightness, upgrading heating and cooling …
