Outline
1. How did it come to be? Supporting policies in
Vancouver
2. Where to next? Vancouver’s Zero Emissions
Building Plan
3. Scaling up: British Columbia Energy Step Code
and NZEr target

Passive House enabling policies in Vancouver
Green rezoning for increased density
o Affects 60% of new development (2.6 million sf/yr)
o Requires LEED Gold and 22% below ASHRAE 90.1
OR Passive House
Thick wall exclusion and setback allowance
Training of permitting staff and inspectors; staff

Source: City of Vancouver
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
B.C. Energy Step Code
Working
Group
Collaborative design
But how does that relate to base code evolution?...
Thought Leader Forum, June 2015
2 days, 50 organizations, 82 participants:
Can we get new buildings ‘net-zero ready’ by 2030?

Call to Action on Climate and Energy
in the Building Sector
A subset of the 100+ signatories: local governments, organizations, businesses, etc.
B.C.’s new Climate Plan
Code to require Net Zero
Ready by 2032
Incentive program for high

… but nothing on existing
buildings.
