When home performance stays invisible, decisions rest on assumptions.

Homes can be undervalued, overestimated, or overlooked for eligible upgrades and incentives. Homeowners overspend on energy bills and organizations make blind decisions.

WITH COBNECT

Every home's energy performance becomes measurable, comparable, and actionable for homeowners realtors inspectors municipalities utilities lenders

INSIDE YOUR REPORT

The full story of a home

Every Cobnect report turns home energy data into answers you can act on. Here's what becomes visible.

ENERGY RATING

See where a home really stands.

One clear rating places the home on a scale from net-zero to high-usage, side by side with the same home built to today's standards.

Example of a Cobnect energy rating card. It shows an estimated annual energy use for a sample home, plotted on a scale from net-zero to high usage, so homeowners can see how their property compares to a new-build standard.
ENERGY USE BREAKDOWN

Find out where the energy actually goes.

Heating? Hot water? Appliances? The report splits annual energy use by system. So the biggest opportunities are obvious before a single dollar is spent.

Example of a Cobnect energy use breakdown card. It shows how a home's total energy consumption is typically split across heating, hot water, cooling, lighting, appliances, and other uses, displayed as a donut chart.
WHERE HEAT ESCAPES

See where heat and money are leaving the house.

A component-by-component view of heat loss shows whether the attic, the walls, the windows, or the drafts deserve attention first.

Example of a Cobnect heat loss breakdown card. It shows the percentage of heat that escapes through each part of a home's building envelope — foundation, exterior walls, windows and doors, drafts, and the attic — illustrated with a house diagram and horizontal bar chart.
CLIMATE & RUNNING COSTS

Know the footprint. Know the price tag.

Estimated annual carbon emissions and running costs, in plain numbers

Example of a Cobnect climate impact and running cost card. It displays a sample home's estimated annual carbon emissions and estimated yearly energy costs, broken down by energy source, so homeowners can understand both the environmental and financial impact of their home's energy use.

WHO IS COBNECT FOR

How Cobnect helps homeowners

Save money on energy bills

See exactly where your home loses heat and drives up costs. We show you which areas waste the most money, so you know where to invest for real savings instead of guessing and hoping.

Replacing your furnace? Adding insulation? Planning a major upgrade? Know which improvements will actually pay off before you spend a dollar. Stop wasting money on changes that don’t deliver.

Traditional assessments cost CA$500-600, and you might find out you’re not eligible for rebates after paying. Get an estimate first to know if you qualify before investing in the full process.

Energy-efficient homes sell for more and sell faster. When you’re ready to list, you’ll have the documentation buyers want to see: proof that your home performs, not just promises.

How Cobnect helps professionals

Data competitors don't have

Real estate moves fast, and clients have endless options. Energy performance data is information most professionals can’t provide yet. When you show up with insights about how a home performs, its carbon footprint, and sustainability score, you’re answering questions that matter more to buyers every year.

When buyers want to know heating costs, asking sellers for their bills feels personal, and those numbers don’t even tell the right story. They reflect personal usage patterns, not the home’s performance. Show energy data based on the property, not someone else’s private consumption.

Comparing five listings for a client? Pull energy data on all of them in minutes instead of waiting weeks for individual assessments. Help clients make decisions faster by showing them which properties are worth pursuing and which ones hide expensive problems.

When you’re pricing a listing or advising on an offer, back it up with energy data. A home that looks premium but bleeds heat? That’s leverage in negotiations. An efficient home in a competitive market? That’s a selling point worth money.

How Cobnect helps Municipalities & Enterprises

Instant Home Energy Intelligence Across Your Entire Portfolio

You get accurate energy performance data for every property you manage, instantly and without site visits. You can see the complete picture of energy use, operating costs, emissions, and climate risk across your portfolio, so you can make faster decisions, stay compliant, and plan with confidence.

Every property gets evaluated the same way through our structured, physics-informed model. This gives you a consistent dataset you can rely on for forecasting risk, planning electrification, modeling resilience, and tracking your long-term GHG reduction progress.

You can see which homes are the least efficient, consuming the most energy, or producing the highest emissions, and understand exactly why. This helps you prioritize where to invest, which incentives to offer, and how to adjust underwriting, so you can focus resources where they create the most measurable impact.

Traditional audits, on-site inspections, fragmented data, and slow intake processes add cost and friction. You can automate property screening, climate-risk evaluation, and upgrade targeting at scale. This reduces operational costs while accelerating your progress on GHG commitments, resilience goals, and portfolio performance.

What is Cobnect?

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.

No. Cobnect works from a home’s structural characteristics and available data, with no utility bills required. 

A Full Report tells you how a home is likely to perform on energy before you commit, including where it loses heat and its estimated running costs. It is a low-cost way to avoid an expensive surprise after you move in.

Cobnect adds a home energy layer to your inspection deliverable without adding a site visit or hours of work. Results come back in minutes, so you can include a credible energy performance summary in the report you already provide.

A Cobnect report gives your buyers and sellers a clear view of a home’s energy performance that most agents cannot offer. It is a differentiator on a listing and a trust-builder with a buyer, delivered under your brand as part of your service.

Cobnect surfaces portfolio and neighbourhood-level insight on energy risk and retrofit opportunity. Municipalities use it to identify retrofit priority zones, and financial institutions use it to understand energy risk across the homes they finance.
