Building Achieves 75 Percent Reduction in Heat Flow with Foam Insulation
Dow and ORNL Give 50-Year-Old Building an Energy Efficiency Retrofit

MIDLAND, MICHIGAN — November 2, 2010 — Dow Building Solutions, a business unit of The Dow Chemical Company (NYSE: DOW), and Oak Ridge National Laboratory (ORNL) have taken the first step toward tackling one of the biggest environmental concerns – the amount of energy consumed by the 4.8 million commercial buildings in the U.S.,1 many of which were built before today’s energy efficiency standards. Dow, ORNL, and design-build firm, Paramount Metal Systems, have turned a 50-year-old building at ORNL into a state-of-the art, energy efficient research facility. Initial test results show a 75 percent reduction in heat flow, resulting in a projected 75-80 percent monthly savings in energy costs.

ORNL selected the facility as a test site to demonstrate that retrofitting older buildings is a viable, cost-effective option to achieve an immediate reduction in energy consumption and greenhouse gas emissions. Buildings account for 43 percent of the United States’ carbon emissions2 and, according to a recent McKinsey study, insulation is one of the most cost-effective means of reducing energy consumption and the generation of greenhouse gases.3 According to the EPA’s ENERGY STAR Challenge, improving the energy efficiency of U.S. commercial and industrial buildings by 10 percent would reduce greenhouse gases equal to the emissions from about 30 million vehicles.4

“The annual "utility bill" for commercial buildings is $155 billion.5 If you consider the number of buildings in the U.S. that were built before today’s energy efficiency standards, you can see there is a tremendous need as well as a tremendous market opportunity,” said Doug Todd, market manager, commercial construction, Dow Building Solutions, North America. “Dow’s commitment to sustainability, combined with our exceptional building science expertise and proven products, makes us a natural part of the solution.”

Unusual Design, Rigorous Standards
Built in the 1960’s, the ORNL research facility’s unusual design – metal construction with a sloped roof attached to a masonry building with a flat, modified bitumen roof – made the retrofit a challenge. But this is also what made it a perfect model – it addressed many of the challenges that a design-build firm may encounter when retrofitting an older building.

ORNL’s objectives for this ambitious retrofit were to increase the building’s sustainability and energy efficiency and make it suitable for sensitive ongoing research, to participate in its own Sustainable Campus Initiative, and to establish long-term energy efficiency testing of the retrofit itself.

“ORNL established very stringent performance energy efficiency targets, hired a seasoned retrofit consultant and design-build firm, and took a solutions-oriented, science-based approach, rigorously analyzing every product before choosing Dow Building Solutions as the insulation provider and technical collaborator for this challenging project. We look forward to the long-term performance measurement results,” explained Todd.

Before selecting Paramount Metal Systems as the design-build firm for the retrofit, André Desjarlais, group leader for Building Envelopes Research, ORNL, established the minimum R-values requirements, moisture migration targets, and an overall goal of exceeding current code requirements of the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). One of the challenges Paramount and ORNL faced was there weren’t any physical, provable metal building retrofit projects that they could test for retrofitting performance. “As a result, a highly-skilled team was commissioned to design a demonstrable project used to display the measurable benefits of various cool roofing technologies and framing systems,” said David Dodge, president of Paramount Metal Systems. “ORNL wanted a high-quality retrofit job with proven solutions. We selected Dow Building Solutions based on its quality products and building science experience and know-how.”

The complete building envelope retrofit relies on THERMAX™ Insulation, FROTH-PAK™ Foam Insulation kit and GREAT STUFF™ PRO Insulating Foam Sealant from Dow to help exceed design targets. “This project demonstrates Dow’s ability to respond to the growing retrofit market by applying today’s insulation solutions and technologies to existing buildings, bringing them up to or even beyond current codes, and providing a return on investment through energy savings year after year,” Todd noted.

“Every product selected for the retrofit project was carefully researched and chosen based on performance,” said Desjarlais. “The result is a building that looks brand new, exceeds ASHRAE energy efficiency code, and provides a consistent, comfortable working environment for the people conducting research inside. As we continue to monitor thermal performance over the years, we believe this retrofit will serve as a standard against which to measure other retrofits.”
