Spray foam is used in the building’s envelope to create maximum energy efficiency, high closed cell spray foam R value, and airtightness. This type of insulation successfully contributes to the thermal barrier, minimizing energy loss and maintaining stable temperatures within the building.
Energy performance
The combination of the wondrous effects of spray foam coupled with solar panels significantly increased the generation of renewable energy on-site, giving the Bullitt Center the ability to produce as much energy as it consumed. The spray foam allowed the project to retain heat, energy, and moisture without emitting harmful toxins or wasting resources.
Advances in sustainability development
The Bullitt Center’s design and performance have made it a role model for sustainable construction. While the building may not be a traditional residential project, the use of spray foam and its insulation R value for insulation clearly demonstrates the material’s superior potential to achieve outstanding levels of energy efficiency and sustainability.
Grand Rapids Residence
A private residence in Grand Rapids, Michigan sought to become one of the most energy-efficient homes in the area. The builders and owners of the structure focused on and prioritized sustainability from the very beginning, employing various green building techniques.
Use of polyurethane foam in the project
The surfaces to be insulated were the walls, roof, and basement of the building. They needed to choose a material that would provide high-quality thermal performance and reliable moisture protection, taking into account the climatic conditions of Michigan. The choice was thus made for spectacular spray foam R value.
Energy performance
The airtightness created by polyurethane foam insulation significantly reduced the home’s heating and air conditioning needs. By reducing the load on the heating systems, energy consumption was reduced by 40% compared to similar buildings without polyurethane foam insulation.
Renewable energy integration
The energy efficiency provided by sprayed polyurethane allowed for the installation of a more economical solar panel system. This system made it possible to cover a significant portion of the house’s energy needs and increase its level of sustainability.
LEED certification
The Grand Rapids residence has achieved LEED Gold certification, demonstrating its excellence in energy efficiency, water conservation, and indoor climate quality. Polyurethane foam insulation successfully achieved the required honors for this prestigious certification.
Building America program
Building America was introduced by the US Department of Energy and is aimed at improving the energy efficiency of residential buildings throughout the country. The program tested various insulation methods, including polyurethane foam, on homes built to high-efficiency standards.
Test parameters and methods
Homes located in different climates were renovated using polyurethane foam insulation. The performance of these houses was assessed over a certain period of time, recording their energy consumption, temperature stability, and indoor humidity. The purpose of the tests was to compare the effectiveness of spray foam with other traditional materials such as rockwool and cellulose.
