Agenda

 

THIS MONTH’S PRESENTATION

INSULATING MULTI-WYTHE MASONRY WALLS & NEW THERMAL MODELING METHODS

 Len Anastasi presents a method of insulating existing multi-wythe masonry exterior walls where a ventilated hygric buffer zone is built into the exterior wall assembly. This system has been installed on more than two dozen buildings in the northern third of the country and no problems have been experienced. Hygrothermal modeling will be run to show the effectiveness of this system.

Tony Fontanini (Fraunhoffer Center For Sustainable Energy Systems CSE) also will present on a new model that his organization has developed for attic and roof thermal simulations.

NFPA - FOAMED PLASTIC INSULATION & MEMBRANES

  • National: The 2009 and 2012 International Building Codes requires the testing (to NFPA 285) of cavity wall assemblies with plastic foam insulation, with some exceptions. Few assemblies have been tested to this standard. There is also a new provision in the 2012 International Building Code requiring weather resistive barriers to pass NFPA 285. A proposed code change has been submitted to NIBS to allow Foam Plastic insulation if fire stopped, as allowed in the Canadian Building Code.
  • Local: A group of BEC members is investigating whether a change to the Massachusetts code regarding foam plastic should be proposed (there is no need to address membranes, since Massachusetts has not adopted the 2012 code.) Two possible proposals are under consideration: one to remove requirements for NFPA 285 compliance entirely and one to remove the requirement in sprinklered buildings. A meeting with BRSS staff or state code officials has been suggested as a way to begin the process.
  • Draft code language allowing foam plastic insulation without NFPA 285 compliance is being prepared for review.

BEC- AWARD 2012

 The BSA is incorporating the BEC award into their 2012 Design Awards program. As part of the 2012 Sustainable Design Award, they are creating a special award within that program to acknowledge excellent building enclosures.  The BEC is co-sponsoring the Sustainable Design Award program.
