Get a complete picture of any home’s energy rating, heat loss areas, climate impact, and upgrade priorities. Data-driven and instant results with no site visit or expertise required.
Homes can be undervalued, overestimated, or overlooked for eligible upgrades and incentives. Homeowners overspend on energy bills and organizations make blind decisions.
01
Answer a few simple questions about your home’s location, age, and key characteristics. Takes under five minutes, no expertise needed.
02
Our AI engine combines real building physics, localized climate data, and hundreds of thousands of Canadian home records to accurately assess your home’s energy performance.
03
Your personalized home energy dashboard is ready instantly, covering energy rating, climate impact, upgrade priorities, and comparison to similar homes nearby.
We are environmental researchers, building scientists, and AI engineers. But first, we are Canadians who believe every homeowner deserves to understand the place they live in.
So we did the hard work: combining hundreds of thousands of real Canadian home records with purpose-built technology and years of careful refinement.
Because more people should be able to understand their home’s performance and impact without the barriers of time or expense.

Where are your energy dollars going? We’ll show you exactly where your home is losing heat and wasting money, so you can focus on upgrades that actually matter.
Whether you’re buying, selling, planning upgrades, or analyzing your portfolio, you need the real story about how a home performs. We give you the energy data to make the right call.
Energy costs are rising and climate is changing. We help you understand your home’s climate impact and resilience, so you can invest in improvements that protect your finances and your future.
Cobnect is a home energy intelligence platform that makes any home’s energy performance visible, measurable, and actionable. Share a few details about any home and instantly get a complete data-driven picture of its energy rating, heat loss areas, climate impact, and upgrade priorities. Fast, accurate, and built on real Canadian housing data.
Cobnect uses physics-informed machine learning, a gray-box approach that balances AI predictions with building science. The model is trained on millions of real Canadian data points, analyzing your building envelope, mechanical systems, and local climate to predict energy performance. The result is an accurate picture of how your home performs and where the biggest upgrade priorities are.
Cobnect’s predictions for total annual home energy use and the resulting climate impact show over 90% alignment with traditional on-site energy assessments, based on extensive testing across audited homes. We continuously validate, monitor, and refine our methodology to maintain reliable performance over time.
Cobnect evaluates the performance of the home itself rather than the specific routines of the people living in it. Every home is assessed under consistent and typical household assumptions, which avoids the variability created by individual lifestyle choices.
This approach highlights the building’s true energy characteristics and ensures that Cobnect’s results are clear, reliable, and comparable across different homes.
No. Cobnect provides independent, asset-based insights to help anyone understand a home’s performance and make informed decisions. Our results cannot be used for rebate or loan programs that require an on-site EnerGuide audit.
For programs that do not require an on-site EnerGuide assessment, Cobnect may be a suitable fit. For those that do, Cobnect works well as a pre-screening tool to help you decide whether a full on-site audit makes sense before committing.
Cobnect is currently available across Ontario and supports low-rise homes such as detached, semi-detached, and townhouses. We are actively expanding our coverage to additional regions in Canada.
Completing the home questionnaire usually takes only a few minutes. Once you finish, your dashboard and downloadable PDF report are ready instantly.
Getting started is free. Your home’s overview and snapshot are available at no cost, giving you an immediate sense of how your home performs.
To unlock the full home energy report, including your detailed energy rating, heat loss areas, climate impact, cost analysis, upgrade priorities, and benchmark against similar homes, a one-time purchase is required.
Just your home’s address and a few basic details. You will be asked about your home type, approximate year built, size, and heating system. No utility bills, blueprints, or technical expertise required. Most people complete the questionnaire in under five minutes.
Yes. Cobnect is built for anyone who needs to understand a home’s energy performance, not just the homeowner. Realtors can assess listings, inspectors can add energy context to their reports, lenders can evaluate properties, and municipalities can profile their housing stock. Any home in Ontario can be assessed, regardless of who initiates the report.
Your report is a starting point for smarter decisions. Homeowners can use it to prioritize upgrades, explore potential incentive opportunities, and understand their energy costs. Buyers and sellers can use it to inform negotiations or support a listing. Professionals can share it with clients or use it to guide retrofit recommendations. Your report is also downloadable as a PDF, making it easy to share with anyone involved in a decision about the home.
A few details about your home is all it takes. We’ll handle the rest and show you exactly how your home is really performing.
