Staff draft recommendation: • Requirements effective three months after bylaw
adoption.
• Active rezoning and development permit applications at ESC adoption have one year after bylaw adoption to submit an acceptable Building Permit application under previous requirements.
• Projects endorsed by Development Permit Panel within six months of ESC adoption will have one year from DP issuance to submit an acceptable BP application under previous requirements.

Energy Advisors
23
Staff draft recommendation: (per existing City policy for registered professionals) • Energy Advisors are to provide proof of general and professional liability
insurance: • at application for building permit, and • prior to occupancy
Note: •Under the BC Building Code, use of the EnerGuide Rating System / HOT2000 for energy modelling comes with a requirement to submit files to NRCan for quality assurance purposes. [Section 9.36.6.4. and A‐9.36.6.4.(2)(b)]
Non - Compliance
24
City of Vancouver policy: If post-construction blower door test result is above 5.5 ACH50: -Implement mitigation measures to improve building performance to 5.5 ACH50 or better; and -See below. If post-construction blower door test result is above [target] but below 5.5 ACH50: -Provide EnerGuide report showing 5.5 ACH50 or below; -Pay for two staff responsible for airtightness to attend one-day airtightness techniques training course, and show proof of course registration.

BC Housing study and preliminary
analysis of common low-cost upgrades
Costing / Metrics Study
26
In Brief…
Largest energy modelling exercise for a building
code in Canada
Costs were extensively vetted by industry
Tested 15 building archetypes for both Part 9 and
Part 3, for all BC climate zones
Key focus was to measure the potential impact of
the policy on construction affordability and
practicality

“In most situations, builders can achieve the Lower Steps for less
than a 2% construction cost premium above that of a home built to
the requirements of the BC Building Code.”
