A Decarbonization Platform Built for Your Portfolio

“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, piloted Cortex in a single building with the goal to:

  • Reduce their carbon impact
  • Meet the increasing demand from investors
  • Improve GRESB scores
  • Make progress towards Local Law 97 standards
  • Increase asset value

After piloting our platform in this first building, Savanna saw savings of over $250K in operating expenses, an increased asset value of $5M, and improvements to their environmental impact.

Once Savanna saw Cortex quickly deliver on these goals, Managing Partner Nick Bienstock decided to incorporate the Cortex platform across Savanna’s portfolio, creating not only a more sustainable portfolio, but a more valuable one. He realized that, while Cortex provides value in individual buildings, the real power of Cortex machine-learning platform lies in portfolio-wide acceleration. 

To date, Cortex has supported Savanna across their portfolio in improvements in ESG performance 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.
