Additional Information  

ASHRAE TC 4.4 is sponsoring the following seminar: 

Seminar 42: Can Mass Timber Construction be an Alternative for a Low Carbon Future Construction?

  – 

Location: JW Marriott Tampa Water Street, Tampa Bay 8

Summary:
Cross laminated timber (CLT) is a mass timber material that has the potential to expand the wood building market in North America. When used in place steel and concrete, CLT can offer sustainable structural solution with lower environmental impacts. However most environmental impact assessments don’t consider variation in transportation impacts with the CLT supply chain or their end-of-life fate when calculating life cycle impacts.  The mass timber components can offer a lot of versatility in application.  Thus, this seminar provides 1) construction and development drivers for the use of mass timber and 2) latest research on hygrothermal and energy-saving potential.
