BAIHP TECHNICAL ASSISTANCE
The BAIHP team provided technical assistance to HUD Code
Home manufactures, modular home manufacturers, and site builders
including Habitat for Humanity International and its affiliates
throughout the nation. Site builders receiving technical
assistance are located primarily in the hot-humid region
of North and Central Florida.
Systems engineering forms the core of the Building America
approach. BAIHP Industry Partners evaluate the integration
of their construction standards and consider improvements
that enhance energy efficiency, durability, indoor air quality,
and health of their homes. The Industry Partner decides which
improvements to implement.
In providing technical assistance BAIHP generally recommends
improving equipment efficiency and reducing conditioning
loads while taking durability and health issues into consideration.
Some examples include:
Improving Equipment Efficiency
- High efficiency, correctly sized heating and cooling
equipment
- Interior duct systems and unvented attics
- High efficiency water heating, appliances, and lighting.
Reducing Conditioning Loads
- Well orientated and shaded windows
- Climate appropriate windows characteristics
- Reflective or absorptive surfaces (roof, wall)
- Continuous thermal, moisture, and air barriers
Durability and Indoor Air Quality
- Fresh air ventilation
- Moisture control
- Balanced/controlled air flow
- Reduced long term maintenance needs
It is the combination of these improvements that enables
the BAIHP Industry Partners to achieve high performance homes (Figure
2) to move the homebuilding industry toward DOE’s
2010 goals. Table 2, Homes Built in Partnership with
BAIHP , shows BAIHP Industry Partner production in 4
categories:
- Category A: Homes meeting the Building America
program goal of saving 40% of heating, cooling and water
energy use, incorporating fresh air ventilation, and including
superior durability and health features. HERS scores are
greater than 88.6.
- Category B: Homes meeting the EPA Energy Star
criteria for saving 30% of heating, cooling, and water
heating energy use.
- Category C: Homes with energy efficiency improvements
that fall slightly short of the EPA Energy Star criteria
for saving 30% of heating, cooling, and water heating energy
use. HERS score of approximately 85. Also homes designed
and built to this level or higher that have not been specifically
rated and tested by BAIHP.
- Category D: Manufactured
homes built with substantially leak free ducts (Qn OUT £ 0.03).
This category may include some Category B and C homes.
Since inception, BAIHP has assisted home builders and manufacturers
to construct:
- 11,767 homes built to Energy Star level or better (Category
A and B, Table 2)
- 11,746 homes built 30% to 50% better than the HUD code
- approx 5% below Energy Star (Category C, Table 2)
- ~46,400 manufactured homes with airtight duct systems (Category
D, Table 2)
- Estimated energy savings to homeowners: Over $10 million
annually
Section II describes each BAIHP Industry Partnership, arranged
alphabetically. Readers may contact the BAIHP researchers noted
in the heading of each summary for further information. Many
of these Industry Partners are also featured on the BAIHP website
at www.baihp.org.

Robinson Homes in the Cobblefield community (Gainesville,
Florida) reduce energy bills for individual homeowners while
pushing the standard of building closer to DOE’s 2010
goals.
