  • Survey Says: Dealers Are Slowly Getting Greener, but Skepticism Persists

    In March 2009, PROSALES magazine conducted an online survey of LBM dealers, distributors, and manufacturers regarding the state of the green construction movement in their communities as well as whether they had taken action to green their own operations. The Survey indicates dealers are getting more active in green issues, even though a significant number say there’s little demand to do so. A small majority of dealers responding to the nationwide, online poll said they’re getting asked more often these days about green, but 41% still categorize interest in their area as nonexistent or barely there. To check out how dealer responses from our area compared to the rest of the nation, click HERE.

Biomass Energy – An Emerging Opportunity for the Forest and Agricultural Sectors

A marked shift toward greater use of renewable energy is underway. A key element of renewable energy development is biomass, which today provides about one-half of renewable energy generation nationwide. To balance societal needs for renewable, less polluting energy sources with desires for healthy and diverse forests, one approach taken in Minnesota was the development of “Biomass Harvesting Guidelines.” Click HERE for full article.

  • The NLBMDA Outlook

     

1. IS THE TAIL WAGGING THE DOG? - Op/Ed by Valerir R. Hansen, LBMI Trustee

Today our industry is experiencing the most significant housing downturn in at least a generation. We’re also at the threshold of a new era in American home building, one that will spin off new construction methods, new materials, and require a new attention to process – or a return of old-fashioned craftsmanship. It’s time for lumber dealers, truss manufacturers, and the ALSC to take the leadership in establishing an eco-standard for dimensional lumber. CLICK HERE FOR REST OF ARTICLE

2. LBMI Formal Request to the ALSC 

The Lumber and Building Materials Institute (LBMI), the research and education foundation of the NLBMDA, and the LBMI Green Building Council, respectfully request the American Lumber Standards Committee (ALSC) to adopt a new eco-forest management standard, accredit agencies to certify the standard, and establish a corresponding eco-label (grade stamp).
