The following three topics were addressed during this meeting: 

• Proposed Change Form (PCF) 2061 Overheating in Dwelling Units – The Standing Committee was asked to consider three potential options for moving forward on the overheating PCF that were shared during the meeting, since it will not be possible to address outstanding issues and public review comments in time for the September 11th deadline for the 2025 NBC.  The Committee agreed to recommend moving forward with solution #2 which includes “a cooling load trigger (BTU) for a single space in a dwelling unit, which if exceeded would require cooling facilities to be supplied.” CSA F280 would still be referenced to the size required cooling appliances.”   
  CHBA expressed concerns that the experts involved in the overheating task group had not been invited to participate in this meeting.  We were advised the task group will be consulted once the Board has made a decision on how to move forward following their September 6th in-camera meeting. 
  The following pros were identified with this solution: 
  
  • Would address many public comments, noting that this solution better reflects the real-world problem, so only regions and homes needing cooling facilities would be required to provide them. 
    
  • Only a single “refuge” space would need to comply with the maximum indoor temperature. 
    The following cons were identified with this solution:  

• A “long” deadline extension would be needed to send the PCF back to public review, and the PCF would not be available for the first publishing of the NBC 2025 (despite the PTs saying they need it for this publication). (Could be published as an urgent interim change) 
  Passive measures were also identified for “future work”: 
  • Future work would focus only on how to account for passive measures to limit cooling loads (e.g., thermal mass, phase change materials, etc.), and re-evaluate the cooling load trigger.  

• PCF 2048 – Specific Wind and Snow Loads in Part 9 – The Standing Committee reviewed public review comments submitted by CHBA BC and CHBA which called for a plain language explanation of the proposed change.  The Committee decided this was not required and voted to move forward without any further changes to the proposed change or the explanatory materials.   
   
• Updated TPIC Standard – A working group has been formed to review negative public review comments from CHBA regarding the updated Truss Plate Institute of Canada (TPIC) 2024 Standard.  CHBA noted the adoption of this standard would create an unnecessary regulatory burden on factory builders that already employ a quality system in line with CSA A277 and recommended that factory builders building trusses for buildings built in their factory be exempted from the new requirements.  The Working Group felt it would be unfair to exempt factory builders from new reporting requirements and recommended the new standard proceed for adoption in the 2025 NBC with no exemptions.
