  7. Overview • Part 1 • NAFS and the Building Code • Energy Codes and Energy Star • Part 2 • CSA A440S1 (Canadian Supplement to NAFS) changes WDMA Canadian Building and Energy Code Update

  8. Part 1 • NAFS Use in Canada • NAFS Enforcement in Canada • Residential Energy Codes in Canada • Commercial Energy Codes in Canada • Energy Acts in Canada • ENERGY STAR WDMA Canadian Building and Energy Code Update

  9. NAFS Use in Canada NAFS -08 and Canadian supplement required No Provincial Code (NBC2010 used Charlottetown, Summerside, and Stratford) No Building Code Act Newfoundland Partial adoption, NAFS required For more detailed information see www.fenestrationcanada.ca WDMA Canadian Building and Energy Code Update

  10. NAFS Enforcement in Canada Very Strong Enforcement Strong Enforcement Limited Enforcement WDMA Canadian Building and Energy Code Update

  11. NAFS Use in British Columbia NAFS -08 Part 9 building now use BC specific performance requirements All other buildings use the Canadian supplement requirements For more detailed information see www.fenestrationcanada.ca WDMA Canadian Building and Energy Code Update

  12. NAFS Use in Ontario OBC 2017 coming next year NAFS -11 and Canadian supplement required NAFS calculator will be updated for NAFS-11 and supplement calculations WDMA Canadian Building and Energy Code Update

  13. Residential Energy Codes in Canada Unique Provincial Energy Code Using NBC 2010 Section 9.36 NBC 2010 Section 9.36 underconsideration For more detailed information see www.fenestrationcanada.ca WDMA Canadian Building and Energy Code Update

  14. Residential Energy Codes in Canada BC NBC 2010 9.36 but U-factor only ON uses U-factor or ER numbers QC uses U-factor and ER Numbers in combination NBC 2010 9.36 uses U-factor or ER May 1, 2016 NBC 2010 9.36 6 month phase in April 1, 2016 NBC 2010 9.36 SB12 energy code to be updated in 2017 For more detailed information see www.fenestrationcanada.ca WDMA Canadian Building and Energy Code Update

  15. Commercial Energy Codes in Canada Unique Provincial Energy Code Using NECB 2011 and/orASHRAE 90.1 For more detailed information see www.fenestrationcanada.ca WDMA Canadian Building and Energy Code Update

  16. Energy Acts in Canada BC Energy Act has requirements for residential and commercial windows, doors and skylights. BC Energy Act is under review. (U-factor only 0.35 BTU/hr*ft2F) ON Green Energy Act cover residential windows only. (U-factor 0.35 BTU/hr*ft2F or ER 17) For more detailed information see www.fenestrationcanada.ca WDMA Canadian Building and Energy Code Update

  17. ENERGY STAR in Canada • ENERGY STAR for FenestrationFebruary 1, 2015 Windows WDMA Canadian Building and Energy Code Update

  18. ENERGY STAR in Canada • ENERGY STAR for FenestrationFebruary 1, 2015 Swinging Doors and Sliding Glass Doors WDMA Canadian Building and Energy Code Update

  19. ENERGY STAR in Canada • ENERGY STAR for FenestrationFebruary 1, 2015 Skylights WDMA Canadian Building and Energy Code Update

  20. ENERGY STAR in Canada • Technical specification alignment with U.S. program • NRCan looking at ways of increasing enforcement of the program. • Options range from “off the shelf” testing by NRCan to an independent testing regime similar to what the EPA does.

  23. Questions WDMA Canadian Building and Energy Code Update

  24. Part 2 • CSA A440S1 History • A440S1 Implementation • A440S1 Review • A440S1 Revision • Comparison • Moving Forward WDMA Canadian Building and Energy Code Update

  25. History • CSA A440S1 developed as a Canadian supplement to NAFS 2008 • Performance calculations for CSA A440-00 moved to A440S1 • A440 Technical Committee worked to align performance calculations with National Building Code • A440S1-09 believed to be aligned with NBC 2010 WDMA Canadian Building and Energy Code Update

  26. Implementation • Once implemented the A440S1-09 resulted in higher wind and water load requirements than the CSA A440.1 standard previously required • Consultation with building code officials, fenestration manufacturers, and other stake holders the A440 technical committee agreed to review the A440S1 supplement document WDMA Canadian Building and Energy Code Update

  27. Review • A440 technical committed to review A440S1 • The water pressure requirements for all building types was found to be higher than previously required • The wind load pressure requirements for Part 9 low-rise buildings were also found to be higher than previously required WDMA Canadian Building and Energy Code Update

  28. Revision • The calculations in A440S1 were reviewed and revised to fall more in line with previous values • The A440 technical committee agreed to the changes and the A440S1-09 document for use with NAFS-08 was revised and will be sent out for public review • The A440S1-15 document for use with NAFS-11 was completed and will also be sent out for public review WDMA Canadian Building and Energy Code Update

  29. Comparison WDMA Canadian Building and Energy Code Update

  30. Comparison WDMA Canadian Building and Energy Code Update

  31. Moving Forward • CSA A440S1-09 and A440S1-15 went out for public review in early May • The documents will both be published later this year • Both documents results in identical performance requirements • Fenestration Canada will be updating the NAFS online calculator to launch as soon as the documents are published WDMA Canadian Building and Energy Code Update

  32. Moving Forward • British Columbia building code has already updated the wind and water requirements for Part 9 low-rise buildings in BC. • The Fenestration Canada NAFS calculator has been updated to include a link to a PDF look up table for the BC requirements • The Fenestration Canada NAFS calculator will be updated to include the BC calculation when the A440S1 changes are made WDMA Canadian Building and Energy Code Update
