Energy Efficient Homes BC
Talk to CoreVal HomesBC is raising the bar. Most builders are still catching up.
The BC Energy Step Code is a provincial performance-based standard that rates new homes by how much energy they actually consume — not by a materials checklist. The Province has been tightening the required Step over time, moving the whole industry toward a net-zero-ready standard.
Most buyers don't know this. And some builders are quietly hoping you won't ask about it until after the contract is signed.
If you're building a new home in Vancouver, Burnaby, Langley, or anywhere in the Fraser Valley, here's what you need to know before you commit to a builder.
What "Energy Efficient" Actually Means Under BC Law
The BC Energy Step Code uses a performance-based system. Homes are rated by an EnerGuide rating and confirmed by third-party testing — including a blower door test at rough-in and again at final completion.
Each Step raises the bar: Step 3 is the current code floor in most BC municipalities. Step 4 and Step 5 (Net Zero Ready) are progressively stricter tiers the Province has signalled it will phase in over time, with Step 5 designed so the home's envelope and mechanical systems could reach net-zero energy consumption with the addition of solar.
Building to a higher Step isn't just about insulation. It requires:
- An integrated building envelope (airtight assembly, continuous insulation, thermal-bridge management)
- A high-efficiency mechanical system — almost always a heat pump in BC's climate
- Controlled mechanical ventilation (HRV or ERV) to maintain indoor air quality
- Third-party EnerGuide labelling and blower door testing
The homes that fail inspection aren't failing because the builder bought bad windows. They're failing because no one designed the air barrier as a system, or the mechanical package wasn't sized to the envelope. That work happens at design — not on site.
Why It Matters for Your Resale Value, Your Mortgage, and Your Monthly Bills
Energy efficient homes in BC come with financial advantages most buyers underestimate.
Lower operating costs. A tighter envelope and a properly sized heat pump mean less energy spent heating and cooling the home, for the life of the building.
Mortgage insurance incentives. CMHC's Green Home program can reduce your mortgage loan insurance premium for homes that meet a qualifying energy-efficiency rating. Ask your mortgage broker what the current refund and eligibility thresholds are at the time you're financing.
Utility rebates on your mechanical system. BC Hydro periodically offers rebate programs for installing a heat pump as your primary heating system. Program amounts and eligibility change — CoreVal factors current rebate eligibility into the mechanical spec from the first design meeting, and will confirm the live program details with you before you commit to equipment.
From the Field — CoreVal Homes
"The clients who've had the worst experiences are the ones whose builders didn't tell them the home needed to be Step Code tested until the project was framed. By then the air barrier decisions are already made. Fix it in design — not at rough-in."
What CoreVal Builds To
CoreVal is a BC Housing-certified custom home builder operating across Vancouver, Burnaby, North Vancouver, Langley, Abbotsford, and the wider Fraser Valley. Every home we build carries the BC Residential Warranty (2-5-10: 2 years labour and materials, 5 years building envelope, 10 years structural) and is built by a CHBA BC member company.
We plan for higher Step Code compliance as standard scope — not as an upgrade added after permits are issued. That means:
- The energy compliance path is decided before design is finalized, not after permits are issued
- Our mechanical specs are written for the specific envelope, not copied from a previous project
- EnerGuide labelling and third-party testing are coordinated as part of our build schedule
- We walk you through the actual energy performance numbers before you sign a contract

The BC Energy Step Code: What Every Buyer Needs to Know
Step — What it requires — Where BC is headed
Step 3 — Current code floor in most BC municipalities — In effect now
Step 4 — A meaningfully tighter envelope and mechanical spec — Provincial target, phasing in over time
Step 5 (Net Zero Ready) — Envelope + mechanical system capable of net-zero with solar added — Longer-term provincial goal
The Province has been raising Step Code requirements in stages since 2017 — ask your municipality which Step currently applies to your permit jurisdiction, since local bylaws can be ahead of the provincial floor.
If a builder quotes you a Step 2 or 3 home today, ask them directly how they're planning to meet a rising Step requirement for any project that won't have its occupancy permit for a few years. Get the answer in writing.
Frequently Asked Questions: Energy Efficient Homes in BC
How much more does it cost to build an energy efficient home in BC?
Building to a higher Step typically adds some cost to construction, mainly in the mechanical and envelope systems. The exact number depends on your lot, program, and site conditions — CoreVal will give you a project-specific estimate at your design meeting. Those added costs are often partially offset by utility rebates, mortgage insurance incentives, and lower lifetime operating costs. Ask your builder for current program numbers, since rebate amounts change.
What is the BC Energy Step Code and does my builder have to follow it?
The BC Energy Step Code is a provincial standard that rates homes on actual energy performance — not prescriptive materials. Municipalities in BC can require different Steps, and the Province has been raising the province-wide floor over time. Your builder is required to meet whichever standard applies to your permit jurisdiction — ask your municipality directly for the Step currently in force.
What is a blower door test and will my new home need one?
A blower door test measures how airtight a home's envelope is by pressurizing the house and measuring air leakage. Under BC's Step Code, homes at Step 3 and above require a blower door test at rough-in (framing stage, before insulation) and again at final completion. The test results must fall within the limits for the Step being claimed. Failing a rough-in test means reworking the air barrier before insulation goes in — expensive and time-consuming if you don't build the air barrier correctly the first time.
Can I get a net-zero home built in Greater Vancouver today?
Yes. Net Zero Ready (Step 5) homes are already being built in Greater Vancouver and the Fraser Valley. They're designed so the envelope and mechanical systems are capable of reaching net-zero energy consumption, usually with the addition of a solar PV system. CoreVal can walk you through the design requirements and available incentives for your specific lot and program.
Does building energy efficient affect my mortgage options?
It can. CMHC's Green Home program can refund a portion of your mortgage loan insurance premium for homes that meet a qualifying energy-efficiency rating — ask your mortgage broker for the current refund amount and eligibility threshold at the time you're financing. Some lenders also offer green mortgage products for qualifying energy-efficient construction.
Build It Right the First Time
BC's Step Code requirements keep tightening. Any project that won't be permitted and occupied for a few more years needs a builder who is already planning ahead, not scrambling to catch up.
CoreVal builds energy efficient homes across Vancouver, Burnaby, North Vancouver, Langley, Abbotsford, Chilliwack, and the Fraser Valley. We're BC Housing certified, carry the full 2-5-10 warranty, and hold CHBA BC membership. We'll tell you exactly what Step Code level your project should target, what it adds to the budget, and what incentives you may qualify for — before you sign anything.
