British Columbia is leading the way in energy-efficient construction, and the BC Energy Step Code is at the heart of it all. As of 2025, this performance-based standard is no longer optional, it’s driving how homes are built across the province, especially in municipalities like Vancouver, where Step 3 or higher is now required for most new builds.

So, what does this mean for you as a homeowner planning a renovation or custom home project? Let’s break it down.

Understanding the Step Code: More Than Just Insulation

The Energy Step Code isn’t just about checking boxes on insulation or windows, it’s a holistic performance target for your entire building envelope, mechanical systems, and airtightness.

In 2025, most new low-rise residential homes in BC must meet Step 3, with some municipalities pushing for Step 4 or 5, depending on the project type and location.

Key Areas It Affects:

• Energy modelling is now part of the permitting process.
• Builders must conduct blower door tests to prove airtightness.
• Mechanical systems (like heat pumps and ventilation) need to hit efficiency benchmarks.
• Envelope-first design is becoming a priority, focusing on insulation, window quality, and thermal bridging before adding systems.

Why It’s Good News for Homeowners

You might be wondering: does this mean more cost upfront? In some cases, yes. But the long-term benefits often outweigh the investment.

The Benefits of Step Code-Aligned Construction:

• Lower energy bills from day one
• Better indoor comfort year-round
• Higher resale value as buyers increasingly prioritize energy-efficient homes
• Future-proofing: you’ll already meet or exceed future building code requirements

It also means healthier homes with better air quality, quieter interiors, and more consistent temperatures.
