Our Approach

Energy-Efficient Building

Every Caliber project is an opportunity to build better. We apply building science — air sealing, continuous insulation, and moisture management — to deliver homes that cost less to operate, feel better to live in, and last longer.

Building Science

Not an Add-On.
An Approach.

Most contractors treat energy efficiency as an upgrade package — a line item you add to the quote. We see it differently. Building science is woven into every project we take on, from a kitchen renovation in Beechwood to a custom home in Paris.

Our founders came up through Conestoga College’s engineering program and the trades. That combination means we don’t just know how to swing a hammer — we understand heat transfer, vapour dynamics, and air pressure. We design wall assemblies as integrated systems, not checklists of materials.

The result? Homes that use 30–50% less energy, feel noticeably more comfortable, and don’t develop the hidden moisture problems that silently damage conventional construction.

The Fundamentals

Three Pillars of Performance

01

Air Sealing

Air leakage accounts for 25–40% of energy loss in a typical Ontario home. We treat air sealing as a system — sealing every junction, penetration, and transition with the right material before walls are closed. The goal is a continuous, unbroken air barrier around the entire building. On high-performance projects, we verify with blower door testing.

02

Continuous Insulation

Cavity insulation alone leaves thermal bridges at every stud — framing that conducts heat 3–4x faster than the insulation beside it. Continuous insulation wraps the entire structure in an unbroken layer, eliminating thermal bridging and improving effective R-value by 20–30%. The right material depends on the project — we select based on the specific wall assembly and moisture strategy.

03

Moisture Management

A tight, well-insulated home changes how moisture moves through the building. Without deliberate vapour control, condensation forms inside walls — leading to mould, rot, and structural damage you don’t see until it’s serious. We design every wall assembly with vapour drive, dew point location, and drying potential in mind.

Across Every Project

How This Shows Up in Your Project

Energy-efficient building isn’t a separate service — it’s embedded in everything we do. Here’s how it applies to the projects we take on every day.

Kitchen & Bathroom Renovations

When exterior walls are opened for plumbing or electrical, we seal and insulate before closing them back up. It’s a small addition to the scope that pays dividends in comfort and energy savings for decades.

Whole-Home Renovations

A gut renovation is the single best opportunity to upgrade your entire building envelope. Walls are already open — the incremental cost of proper air sealing and insulation is a fraction of doing it standalone.

Custom Home Builds

New construction is where you have the most control. We design the envelope from the ground up — continuous insulation, detailed air barrier, and a wall assembly optimized for Ontario’s climate. The 3–5% premium pays for itself in under 10 years.

Century Homes

Older homes are where envelope upgrades make the biggest difference. Most pre-1960 homes have no air barrier and minimal insulation. Upgrading during a heritage renovation can cut energy costs in half while preserving the character that makes these homes special.

Home Additions

An addition is new construction attached to an existing building — we build the new section to high-performance specs and improve the connection point where new meets old, which is often the weakest link in the envelope.

ADUs & Garden Suites

A detached ADU is a new build on a small footprint — the perfect candidate for a high-performance envelope. Smaller buildings are easier to seal tight, and the energy savings are immediately felt by whoever occupies the unit.

Frequently Asked Questions

Energy-Efficient Building FAQs

What makes a home energy efficient?+

The building envelope — walls, roof, foundation, windows, and doors. The three key factors are air sealing, continuous insulation, and moisture management. A well-designed envelope reduces heating and cooling costs by 30–50%.

Can you make an existing home more energy efficient during a renovation?+

Yes. A gut renovation is the ideal time because the walls are already open. Adding air sealing and improved insulation costs a fraction of doing it as a standalone project.

Does energy-efficient building cost more?+

The incremental cost is typically 3–5% more for new builds and $5,000–$15,000 additional for whole-home renovations. This pays for itself in 5–10 years through lower energy bills.

What is a blower door test?+

A test that measures how airtight your home is. A conventional home tests at 3–5 ACH50. A high-performance home targets 1.5 ACH50 or less. We can arrange testing to verify envelope performance on any project.
