This BAIHP partner is currently building 10 to 12 SIP homes
per year. HERS scores on the builder's plans determined that
the homes ranged between 88 to 90, depending on the windows
and water heater chosen. BAIHP provided Marquis Construction
with a list of recommendations to meet Building America durability,
IAQ, and energy savings guidelines. This custom builder's
first home test is scheduled for April 15, 2003.
- Miami-Dade HOPE VI Project
This project is a community revitalization program aimed at
lessening poverty density by demolishing dilapidated public
housing and replacing it with new, less dense housing. In
this HUD-sponsored inner city redevelopment project, about
860 public housing units are being torn down and replaced
with 450 new units. The new units will include duplexes,
townhouses, and single-family homes.
As part of the sustainable team, FSEC participated in the
initial design charette which reviewed project home designs,
made architectural recommendations on wall and roof assemblies,
exterior finishes, and other energy-related design and construction
features.
During 2002, FSEC provided assistance to Miami-Dade Department
of Environmental Resources Management as they emphasized the
importance of Building America principles and techniques to
the Miami-Dade Housing Authority. The Housing Authority
conducted a mandatory value-engineering meeting to ensure
that their Hope VI Project would meet the available budget.
FSEC staff, as well as other stakeholders, took part in housing
discussions and analysis to ensure that the Building America
principles and techniques specified early in the project would
be considered and not engineered out of the project.
FSEC researchers assisted the UCFIE team in conducting an
energy benchmarking study for Nationwide Homes. In September,
personnel traveled to the Nationwide Homes modular plant in
Arabi, Georgia to tour the plant and test two homes for Energy
Star qualification. Recommendations were sent to Nationwide
in a trip report, neither home tested successfully qualified
for Energy Star.
Oakwood Homes, a large HUD code manufacturer, requested an
FSEC duct installation review and consultation on ways to
make the home's systems work better together. In 2002, plant
visits were made to the Oakwood plant in Moultrie, Georgia
and to the Hillsboro and Kileen, Texas plants. Recommendations
for appropriate duct system design and manufacture were forwarded.
An Energy Gauge USA analysis of Energy Star and non-Energy
Star homes in Boston, Minneapolis, and Indianapolis was performed.
(Please see Table 5.) Researchers determined that Oakwood
Homes could meet Energy Star standards if they increased installed
gas heating and cooling system efficiencies, and floor and
roof insulation levels. These results were communicated to
Oakwood management.
