Our Commitment to Energy Efficiency

At Sinclair Homes, everything is built-to-last — and we believe that longevity starts with efficiency. Our industry-leading building practices deliver homes that don’t just comply with Ontario Building Code standards for energy efficiency — they surpass them.

EnerGuide Standards

Our team recently participated in the Ontario Power Authority’s ‘New Home Construction’ initiative, designed to encourage home builders to construct energy-efficient homes to meet EnerGuide standards. All of the new-build Sinclair homes use efficient materials and techniques as part of this initiative.

Energy Star®

Every new home that we build in our current communities are constructed to be Energy Star-certified. As the proud owner of a new Sinclair-constructed home, you get to enjoy reduced energy usage, lower maintenance costs, and a smaller carbon footprint.


At Sinclair Homes, we have experience constructing NetZero Homes. A home is designated ‘net zero’ when it produces as much energy as it consumes. A NetZero home can be up to 80% more energy efficient than the average new home and will produce the remainder of its energy using renewable energy sources. These homes offer a better, more environmentally-friendly living experience for residents.
