Reduce Carbon Emissions and Improve ESG Scores Across Your Portfolio

Commercial buildings are responsible for 28% of all carbon emissions — which is even more than the auto industry. Regulators and CRE investors are responding with penalties and investment strategies that could result in millions of dollars in fines and lost investments. This is why Cortex has developed our machine-learning decarbonization platform — the fastest, easiest, and most cost-effective path to make massive strides towards the decarbonization of your portfolio, all while improving your GRESB scores and increasing your asset value.

Carbon Regulations May Cost You Millions

CRE investors and state-wide legislation are increasing requirements for commercial buildings to reduce their carbon emissions. New York City and Boston are already implementing their strict carbon reduction legislations, with 20 other major cities across the U.S. predicted to shortly follow in their wake. Cortex helps you reduce carbon emissions, improve sustainability scores, meet your investors’ goals, and avoid those massive carbon regulation fines.

Making Decarbonization a Smart Business Decision

“The sustainability and economic benefits are shockingly large.”

– 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 with the goal of quickly decarbonizing their portfolio to improve GRESB scores, meet the expectations of their investors, increase asset value, and fulfill the requirements of Local Law 97.

After piloting our decarbonization platform in one building, Managing Partner Nick Bienstock quickly recognized that the “sustainability and economic benefits are shockingly large.” Achieving 100% payback in just three months, he also reported that they increased the asset value of the first building Cortex was deployed at by $5M by saving $250K in operating expenses. 

To date, Savanna has rolled Cortex out across their portfolio, resulting in dramatic improvements to their GRESB scores, a 21% in portfolio-wide annualized energy savings, and over $1.4M in lifetime financial savings.

Not only have we found Cortex to be extremely cost effective, but its environmental and sustainability benefits are also shockingly large. Having Cortex in place at our properties certainly gives us a valuable jump start as far as the steps we need to take to meet the new emissions requirements in New York.
