History
CSA A440S1 developed as a Canadian supplement to NAFS 2008
Performance calculations for CSA A moved to A440S1
A440 Technical Committee worked to align performance calculations with National Building Code
A440S1-09 believed to be aligned with NBC 2010

26. WDMA Canadian Building and Energy Code Update
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. WDMA Canadian Building and Energy Code Update
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. WDMA Canadian Building and Energy Code Update
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

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

32. WDMA Canadian Building and Energy Code Update
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
