More States Embrace the 2012 IECC, But Not Lovingly

PENNSYLVANIA
General Code Information
In early June, an amended version of SB 1023 passed the State Senate by a 47-1 vote. The bill attempts to do away with the current code adoption process, which calls for two-thirds approval of a code change or it is rejected. The amended version of SB 1023 allows “all proposed code changes to be adopted unless two-thirds of the Review and Advisory Council (RAC) votes them out.” It also adds “two members to the RAC with expertise in building energy efficiency.”

The bill still has to pass the House. On July 2, it was amended in committee and then tabled, so no vote is scheduled for the full House yet. Finally, the RAC has to make a decision on the 2015 IECC by June 2015 and perform the required analysis. (Details of the amendment can be read here: http://tinyurl.com/k3q2swr)

The Living Building Challenge: A green building certification program

THE LIVING BUILDING CHALLENGE is a green building certification program that reaches beyond projects’ physical boundaries. As more green building programs delve into the manufacturing process, they will create a demand for products with established life-cycle assessments (LCSs) and reduced use of harmful chemicals.

In the Beginning…
In 1992, then Sen. Conrad Burns (R-Montana) had secured an earmark of approximately $1.2 million to be administered by the U.S. Department of Commerce’s National Institute of Standards and Technology (NIST) for the intent of funding sustainability projects. At the same time, Montana State University’s (MSU) Office of Research and Technology Transfer was charged with identifying appropriate projects and funding green building technology research.

Do Green Codes and Standards Get in the Way of High-Performance?

What’s The Situation?

High-performance homes sometimes require practices that code officials are unfamiliar with. This lack of familiarity can lead officials to improperly interpret and apply building code to prevent the implementation of high-performance building techniques. Additionally, green codes and standards sometimes encourage practices that aren’t in the best interest of high-performance building techniques.

Three More States Tweak Energy Codes

MINNESOTA
Energy Code Information: The state’s Construction Code Advisory Council approved a draft energy code based on the 2012 IECC. It then moved to a review by the state’s Department of Labor and Industry. A public comment period was held earlier this year, though the state first has to work through the issue of residential sprinklers. Once they finally get to the energy code discussion, they will review the following amendments proposed to both the commercial and residential codes:

Commercial: The IECC commissioning requirements were incorporated into ASHRAE 90.1-2010, so there is consistency between the code and standard.

Residential: Wall insulation R-value is R-21 for the prescriptive table, while the U-value table remains the same as it was. Ventilation requirements have been increased to balanced ventilation (cannot use exhaust or supply).Two options for basement wall insulation: R-15 continuous or R-10 exterior insulation; however, 2.5 ACH50 must be proven.Elements to ensure basement walls are waterproofed, which helps mitigate moisture damage.
