Vancouver Zero Emissions Buildings Plan
2016: 50-64% GHG reduction
2020: passive house performance*
2025: zero carbon(for rezoning)
2016: 60% GHG reduction
2020: near passive house performance
2025: zero carbon(for rezoning)
2014: 50% reduction in GHG intensity
2020: 70% reduction in GHG intensity
2025: zero carbon, thermal load <30 kWh/m2/yr
(9.5 KBTU/sf)
* i.e. Thermal load intensity < 15 kWh/m2 (4.7 KBTU/sf)

B.C. Energy Step Code
Problem
• Local climate leadership led to patchwork of green building
policies
Solution
• Provincially-designed opt-in energy performance
requirements
Principles
• Implementation through partnerships
• “Envelope first” approach
• Measure performance
• Framework valid for next 10+ years@tompierrefs
