Gulf Coast High Performance Affordable Housing Demonstration Project
In Partnership with Habitat for Humanity Affiliates
Volunteers at HFH of Greater Baton Rouge construction site
The main goals of the Gulf Coast High Performance Demonstration Project were to encourage high performance re-building in areas affected by hurricanes Katrina and Rita and to demonstrate that it could be achieved in the challenging, affordable housing sector. Given the opportunity to impact thousands of houses in dozens of communities, the Department of Energy provided abundant technical resources to builders in the region on how to apply Building America’s proven approach to building high performance homes. In many markets across America, this type of technical assistance to production builders created a ripple of change in a challenging post-disaster environment.
Beginning in 2008, the Department of Energy funded BAIHP to build demonstration houses in partnership with affordable housing providers in the recovery zone that sweeps the coast from Louisiana to Alabama. Based on work with other BAIHP partners, researchers developed a standardized approach for achieving a HERS Index of 70 while safeguarding indoor air quality, durability, and comfort. Seven Habitat for Humanity affiliates in Alabama, Louisiana, and Mississippi participated in the project effort to build cost-effective, high-performance affordable housing prototypes. Affiliates in Covington, Slidell, Gulf Port, Foley, and Mobile each completed two demonstration houses. New Orleans Area Habitat attempted two houses but did not pass the thermal bypass inspection required by the Energy Star for New Homes program.
A detailed report on the entire project, including economic analysis, is available at this link:
Technical features of the standardized approach and the training materials provided to participants are summarized on this page

Researchers worked with the builders to evaluate their standard practices and identify a package of improvements to achieve a HERS Index of 70 to 75, while maintaining or improving indoor air quality, durability, and comfort. Special attention was given to the selection of improvements that were appropriate for the construction process and with broad applicability to maximize the benefit of the demonstration. Builders achieved a HERS Index of 59 to 73 when the project was completed in 2009.
Indoor Air Quality Features
Energy Efficiency Features (HERS Index ~70)
Building America researchers conducted three one-day workshops for builders and affordable housing providers. Participants were encouraged to adopt Building America practices and the high performance package. Materials covered the improvement features in the demonstration houses including building science for the hot-humid climate, an introduction to the home energy rating system’s HERS Index, and the Energy Star for Homes process.
Workshops commenced in the following locations:
November 20, 2008
BAIHP presented the Mobile Prototype I project to the general membership of the local chapter of the Air Conditioning Contractors of America (ACCA). A workshop was also produced in conjunction with the Home Builders Association of Metro Mobile. Despite direct mail promotion to over 1700 members of the Home Builders Association, attendance predominately consisted of local raters and other Habitat affiliates from south Alabama and the Florida panhandle. The site visit portion of the workshop generated considerable discussion.
Baton Rouge, LA
December 5, 2008
In conjunction with the LSU AgCenter’s La House and the Capitol District Home Builders Association, BAIHP conducted a workshop worth four CEUs. Attendance consisted of approximately 30 people and included university students and faculty, raters, non-profit home builders, and for profit production builders.
June 23, 2009
BAIHP also partnered with Louisiana State University’s AgCenter program and West St. Tammany Habitat to present a workshop for home builders. Louisiana licensed builders participating received two CEUs. Two additional CEUs were available for participating in the site visit portion of the workshop. There were 20 attendees; of 18 reviews submitted 17 were favorable, with one attendee wanting additional LEED for Homes material.
