The pink are steel-framed construction with exterior insulation, the gray homes are of traditional construction, and the brown are constructed with engineered wood framing on the inside and structural insulated panels.

What is Building America?
Building America is a private/public partnership sponsored by the U.S. Department of Energy that conducts research to find energy-efficient solutions for new and existing housing that can be implemented on a production basis.
What Does Building America Do?
Building America conducts systems engineering research to do the following:
- Produce homes on a community scale that use 40% to 70% less energy
- Integrate onsite power systems leading to "zero-energy" homes that will ultimately produce as much energy as they use.
- Help home builders reduce construction time and waste
- Improve builder productivity
- Provide new product opportunities to manufacturers and suppliers
- Implement innovative energy-and material-saving technologies
By using a systems engineering approach to home building, Building America unites segments of the building industry that traditionally work independently of one another. It forms teams of architects, engineers, builders, equipment manufacturers, material suppliers, community planners, mortgage lenders, and contractor trades. Currently, there are five Building America teams who have worked with over
507 different industry partners.
Throughout the design and construction process, research participants in Building America projects evaluate the interaction between the building site, envelope, mechanical systems, and energy-use factors. In many uses, cost tradeoffs allow the teams to incorporate energy-saving strategies at no extra cost. Building America research participants agree to:
- Provide all construction materials and labor for research projects
- Evaluate their design, business, and construction practices
- Identify cost savings
- Re-invest cost savings in improved energy performance and product quality
- Extend their efforts from discussion of possibilities to development of solutions
- Use a design, test, redesign, and retest process to resolve technical barriers
The research conducted by Building America teams increases the quality and performance of today's homes and provides valuable information for homes of the future. By supporting industry-driven systems engineering research, the Building America Program provides the feedback required to develop critical "next generation" building systems.
