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

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.

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.

Ventilation Requirements in Energy Step Code Energy Step Code – Overview BCBC 6.2.2. - 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.”

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

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.

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

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? Other comments?
