2023 ZERO CARBON STEP CODE AND BC ENERGY STEP CODE REQUIREMENTS FOR NEW BUILDINGS

Consistent with previous updates to Bylaw requirements in July 2020 and July 2022, the expected timing of subsequent requirements in 2025 and 2027 are also included and noted as subject to future Council approval. Similarly, the proposed framework for implementing the ZCSC considers phased timing of these requirements, thereby allowing the development community sufficient time to cost-effectively transition to higher levels of performance by improving design and construction practices, and mitigating potential supply chain issues. Tables 2 and 3 show that Step-level relaxations will be available for both the Energy Step Code and ZCSC in 2023 and in 2025. However, once proposed new Bylaw requirements come into effect in 2027, relaxations would no longer be available, as all new buildings would need to achieve the top perfonnance level for both Energy Step Code and ZCSC at building pennit, pending future Council endorsement.
