A recent test conducted by Oak Ridge National Laboratory’s Buildings Technology Center proves the effectiveness of BioBased Insulation in sealing a home’s building envelope and increasing its energy efficiency.
Two 1,200-square-foot homes of comparable design were constructed by the Women Build Program of the Loudon County Habitat for Humanity in Loudon, Tenn. One was insulated using fiberglass batts, and the other using BioBased 501, an open cell spray polyurethane insulation.
The homes were tested using a blower door to measure how well the building’s shell or envelope prevents outside air from entering. The BioBased-insulated home experienced only 0.08 air changes per hour (ACH) at 4 pascals of pressure. The fiberglass-insulated home experienced 0.16 ACH at the same pressure conditions.
The results show BioBased Insulation did a better job of providing air seal for tightness and energy efficiency.
According to the American Society of Heating and Refrigeration Engineers, most houses experience 0.35 air changes an hour at natural pressure. When outside conditions include winds of 15 to 25 miles per hour, the number of air changes can increase drastically.
New guide for Wood Deck Construction is available
AF&PA’s American Wood Council (AWC) and the International Code Council have published “Design for Code Acceptance (DCA) No. 6 — Prescriptive Residential Deck Construction Guide.” The document provides guidance on the Code Council’s International Residential Code (IRC) provisions for single-level, residential wood deck construction.
With a need in residential construction for simple design tools, AWC has developed this easy-to-use guide for builders and home owners who are constructing single level decks in all areas of the country. The new publication is co-branded with the Code Council and Fairfax County, Va.
Prescriptive solutions presented in the guide are in compliance with the 2006 IRC. Use of the guide will result in design solutions that prescriptively meet the requirements of the IRC. The guide was developed with input from the National Association of Home Builders, the International Code Council, Fairfax County (Va.), Simpson Strong-Tie Company, Virginia Tech, Washington State University, WTCA-Representing the Structural Building Components Industry, Southern Pine Inspection Bureau, APA-The Engineered Wood Association and the Southern Forest Products Association.

NECA is new member of U.S. Green Building Council
The National Electrical Contractors Assn., headquartered in Bethesda, Md., is a new member of the U.S. Green Building Council, a non-profit organization committed to expanding sustainable building practices. NECA and the USGBC are finalizing a workshop on how electrical contractors can become LEED Accredited Professionals in the “New Construction” category. The workshop will be held at NECA’s annual convention in Chicago, Oct. 4-7.
“Our vision is that NECA will be a resource to help our member contractors and their customers ‘go green’ at whatever level they want,” said Rob Colgan, NECA executive director for marketing. “Energy efficient systems are an important aspect of LEED ratings, but their real attractiveness to building owners lies in the money they can save over the life of a building,” Colgan said.
