1. Part 3 Buildings Engagement
Sept. 6, 2017
City of Richmond
Part 3 Buildings Engagement

2. Two Provincial Initiatives Set the Stage
Building Act
Consistency, Competency & Innovation
December 2017 marks the end of local building requirements in bylaws.
Climate Leadership Plan
Establishes a target that all new construction will be net-zero ready by 2032.

3. Local Government Approaches to Energy Efficiency
Energy Step Code – Overview
Eliminating the Patchwork:
Local government adopted a wide range of programs and approaches to address building energy efficiency.
Development industry struggled to stay on top of these requirements.
BC Energy Step Code offers a common standard for achieving building energy goals.

5. What is the Energy Step Code?
A better than Code energy standard
Local Govts can reference in:
Bylaws
Policies
Incentive programs
Density bonuses

8. Ventilation Requirements in Energy Step Code
Energy Step Code – Overview
BCBC Ventilation
“For suites in buildings subject to the [BC Energy Step Code] … outdoor air… shall be supplied to each suite by mechanical ventilation through ducting.”
“The indirect supply of required outdoor ventilation air to normally occupied spaces through corridor pressurization or other indirect systems is not permitted.”

9. Climate Action at the City of Richmond
Energy Step Code – Overview
OCP Targets
Reduce GHGs 33% below 2007 levels by 2020; 80% by 2050.
Community Energy & Emissions Plan
Strategy 2: Increase Energy Efficiency in New Developments

11. Richmond’s Consultation Process
May 2017
Council directs staff to engage in stakeholder consultation
June
Notify province of intent to reference Energy Step Code
July 6th
Introductory workshop
Sept 6th
This meeting – Feedback on City’s proposed Step Code regime
Sept 22nd
UDI Liaison Committee update
October
Engagement – present recommendations
November
Report to PWT Committee recommending Energy Step Code regime

12. What we heard at first meeting…
Will the City keep LEED equivalency requirements?
Will standards differ inside & outside district energy areas?
Air-tightness testing information & training will be valuable for developers, contractors, trades.
Can developers legally share energy benchmarking information with the City on behalf of the ultimate strata?
Costing information was presented.

13. Richmond’s Regime – For Stakeholder Consultation
Energy Step Code – Overview
Require Energy Step Code in Building Regulation Bylaw City-wide
Remove LEED Silver equivalency requirement from CCAP policy
Consider implementing rezoning policy in the future, potentially addressing:
GHG intensity
Enhanced commissioning
Refrigerant & embodied emissions
Indoor environmental quality
Water efficiency & green infrastructure
Building uses not covered in Step Code

21. Grace Period Energy Step Code – Overview
Acceptable Rezoning & DP applications received before the Energy Step Code is adopted will have 1 year (apprx. Dec 2018) to submit an acceptable BP application under previous requirements.
Following its adoption, Energy Step Code will apply to all new permit applications.

25. Discussion Energy Step Code – Overview
How can the City support Part 3 developments in achieving the Energy Step Code performance levels?
Where would you expect additional costs when building to the Energy Step Code? How might these costs be minimized?
What training would be helpful to building to the Energy Step Code? Is there a role for local government?
Approvals – what ideas can you offer to ensure approvals processes are efficient and effective? Do you see streamlining opportunities?
