Adding Foam Insulation to Commercial Building Roofs Proves Beneficial
Bayer MaterialScience LLC and International Council of Chemical Associations reinforce energy saving potential of building insulation materials

Pittsburgh, October 29, 2009 — Two recent studies – one by Bayer MaterialScience LLC and another by the International Council of Chemical Associations (ICCA) – affirm the substantial potential for energy savings and carbon footprint reduction of building insulation materials.

Bayer MaterialScience’s commitment to industry leadership in sustainable energy solutions led a team of company scientists to recently publish “Energy and Environmental Impact Reduction Opportunities for Existing Buildings with Low-Slope Roofs.” The report examines the energy, environmental and financial benefits of adding additional insulation to commercial building roofs.

The importance of this report to construction decision making has been underscored by a recent ICCA study citing that insulation materials for the construction industry offer the biggest opportunity enabled by the chemical industry to impact emissions savings. The ICCA report cited insulation materials as accounting for 40 percent of the total identified equivalent carbon dioxide (CO2e) savings.

“It was gratifying to make a contribution to deeper understanding of life cycle implications for our materials,” said Jerry Phelan, polyiso marketing manager, Bayer MaterialScience LLC. “It was also gratifying that our findings were corroborated by those of the International Council of Chemical Associations.” Bayer MaterialScience, through supply of raw materials to polyiso manufacturers, as well as BaySystems™ polyurethane systems, is a leader in the insulation industry.

The Bayer MaterialScience team’s findings show that substantial energy, carbon footprint and utilities cost reductions are achievable with energy-efficient roof replacement. Carbon footprint is defined as the precise calculation of a product’s greenhouse gas emissions across its entire life cycle from the production of the raw material used in its manufacture through the product’s use to its final disposal.

From a life cycle perspective, the energy saved by adding insulation during roof replacement across the 10 building types studied was 20 to 28 times greater than the one-time energy use required for making raw materials, manufacturing, installing and transporting the insulation; the calculations were based on a very conservative 30-year product life. Phelan noted that the study is attached to and supports proposed U.S. tax credit legislation.

The Bayer MaterialScience research team in addition to Phelan included George Pavlovich, product safety manager; and Eric Ma, polyurethanes marketing manager.
