Essential guidance on HVAC planning, energy code compliance, and system selection for builders and developers in British Columbia.
Planning HVAC for new construction in British Columbia requires navigating an increasingly complex landscape of energy codes, technology options, and sustainability requirements. This guide gives builders, developers, and architects the knowledge they need to design efficient, compliant, and comfortable buildings from the ground up.
Whether you're building a single-family home in Burnaby or a multi-unit development in Surrey, getting HVAC right at the planning stage saves time, money, and headaches down the road.
BC Energy Step Code: What Builders Need to Know
The BC Energy Step Code is a provincial performance-based standard that sets progressive energy efficiency requirements for new buildings. Understanding how it impacts your HVAC design is critical.
Step Code Requirements for HVAC
Each step of the code raises the energy performance bar, directly affecting HVAC system selection:
- Steps 1–2: Allow conventional systems with good insulation
- Steps 3–4: Typically require high-efficiency heat pumps, HRV systems, and enhanced building envelopes
- Step 5: Targets net-zero ready performance — demanding the most efficient HVAC technologies available
Compliance Strategies
Meeting Step Code requirements is about the whole building, not just the HVAC system. Our team works with builders to optimize the balance between building envelope improvements and HVAC efficiency. In many cases, investing in a high-performance heat pump system can offset the need for more expensive envelope upgrades, achieving compliance more cost-effectively.
HVAC Systems for New Construction
New builds offer the advantage of designing your HVAC system from scratch — no compromises, no retrofitting. Here are the leading options for BC builders:
Radiant Floor Heating
Increasingly popular in BC's luxury and custom home market, hydronic radiant floor heating delivers unmatched comfort. When powered by a high-efficiency heat pump or condensing boiler, it provides even, silent warmth throughout the home. Planning for radiant systems must happen early — the tubing is embedded in the slab or subfloor during construction.
VRF for Multi-Unit Residential
For townhome complexes and multi-unit residential buildings, VRF systems offer individual unit control with shared outdoor equipment. This reduces mechanical room requirements, simplifies metering, and gives each unit independent temperature control — a significant selling point for developers.
- Individual unit metering and temperature control
- Reduced mechanical room footprint vs. traditional systems
- Simultaneous heating and cooling across zones
- Lower operating costs and higher tenant satisfaction
HVAC Planning: Getting It Right from Day One
Proper HVAC planning during the design phase prevents costly changes during construction and ensures optimal performance for the life of the building.
Load Calculations
Accurate heating and cooling load calculations are the foundation of good HVAC design. Our engineers use Manual J calculations for residential and ASHRAE methods for commercial to right-size every system. In Vancouver's coastal climate, we also account for humidity control and microclimate variations.
Ductwork Design
For ducted systems, duct design happens during framing — not as an afterthought. Proper duct sizing, sealing, and routing ensure even airflow, minimize noise, and maximize efficiency. Our team coordinates with your framing crew to ensure mechanical chases and duct runs are planned into the structure from the start.
