Making A Difference for Our Clients’ Bottom Line

“This technology, which cost pennies per square foot to deploy, created $5,000,000 in value for us in a single investment.”

– Nick Bienstock, Managing Partner of Savanna

Savanna, a series of real estate investment funds with millions of square feet throughout New York City, turned to Cortex when they needed to reduce operating cost and increase asset value, meet the sustainability expectations of their investors, and fulfill the requirements of Local Law 97. After deploying our machine learning platform in just one building, Managing Partner Nick Bienstock quickly recognized that the “sustainability and economic benefits are shockingly large.”

With approximately $250,000 per year in savings in this one building, Bienstock reported that, because office buildings in New York sell at 5-cap, the $250,000 in incremental NOI is valued at $5,000,000 when the building is sold.

Savanna has now deployed Cortex widely across their portfolio as a trusted partner in increasing asset value by reducing operating costs, improving GRESB scores, and reaching the sustainability goals of both Local Law 97 and their investors.

Frequently Asked Questions

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 We Need to Purchase Additional Sensors or Replace Any of Our Existing HVAC Equipment?

No, there are no required upgrades to your equipment required and need to invest in any additional sensors to use Cortex. 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. The first step to saving energy and operation costs starts with optimizing the systems you already have in place, rather than investing in expensive, new systems.

How Can Cortex Help Me Ensure Tenant Comfort?

Your building systems provide thousands of data points that are unused. Our platform gives your building operations access to that data, and makes real-time recommendations to keep floors the right temperature for tenants while reducing the amount of energy needed to maintain that temperature. If there is a problem with one of your sensors, Cortex can help your engineers identify the problem before tenants complain.

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.

What Reports Are Provided by Cortex?

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.

Why Cortex?

Our platform is your first step and most important step to decarbonization. It is the fastest, easiest, and most cost-effective method to reach your ESG goals in comparison to traditional capital expenditures. Cortex will provide you with the opportunity to reduce carbon emissions and operating costs while increasing NOI and asset value, without compromising the tenant experience or disrupting your current operations.
