Our machine-learning platform provides the fastest, easiest, and most cost-effective path to decarbonizing your office building. Empower your buildings’ engineers with the real-time, asset-specific recommendations needed to optimize your building operations, conquer your sustainability goals, and build a better future for all.
Fastest Way to Meet ESG Goals
Climate change is not slowing down, and there is no time to waste. Our platform uses data from your buildings’ existing systems so you can start reducing carbon and energy usage immediately.
Reduce the #1 Source of Carbon Emissions
Commercial real estate accounts for 28% of all carbon emissions – that’s more than the auto industry! But, together, we can reduce our carbon footprint. We already reduce 22.5K tons of CO2 each year for our clients.

Frequently Asked Questions
Will Cortex Help Our Assets Comply with ESG Regulations and Avoid Fines?
Yes! We know that carbon reduction regulations are already in place for some commercial buildings, with many more soon to fall under these limits. Additionally, we support state and local incentive programs (where available) to help offset the costs to reduce carbon emissions. Our platform is also unique in our accessible digital reporting. When you use Cortex, you will always have access to reporting information that allows you to track ESG improvements, energy usage peaks, and overall savings at the touch of your fingers.
How Can I Prove or Show ESG Improvements to My Investors?
Cortex provides automated usage, cost, and energy savings reports to users each month, as well as executive summary reports to visualize your savings over time. These reports are accessible in the Cortex dashboard anytime, and your dedicated customer success team will schedule time at your convenience to review results with you personally on a regular basis.
We also pride ourselves on the personalized experience our dedicated customer success team, led by industry expert and experienced engineer Don Kasper, provides our customers. If your success is dependent upon tracking certain metrics or working within specific reporting, we’ll work with you closely to develop a plan custom to the results you need to show. Either way, we’ve got you covered.
Do We Need to Purchase Additional Sensors or Replace Any of Our Existing HVAC Equipment?
No, there is no requirement to upgrade your equipment and no need to invest in any additional sensors. We have spent nearly a decade building a platform that learns the intricacies of your existing equipment in order to empower your engineers with the insight and recommendations they need to get the most out of the equipment you already have. This means no disrupting operations, and no huge capital investments for new equipment, hardware, or sensors required
How Soon Do I Start Seeing Payback on My Investment in Cortex?
Because we use your existing equipment and data, you should start seeing results as soon as the system is set up, usually within three- to six- months. Most customers report that their savings are twice their fees in year one, and five times their fees by year three.
Do you track GRESB score improvements?
While GRESB is not something incorporated directly into the Cortex platform at this time, we pride ourselves on the personalized experience our dedicated customer success team, led by industry expert and experienced engineer Don Kasper, provides our customers. If your success is dependent upon tracking certain metrics or working within specific reporting, we’ll work with you closely to develop a plan custom to the results you need to show. Either way, we’ve got you covered.
