Gregg Fischer, Director of Energy Systems, Tishman Speyer

On May 24, 2018, New York Advanced Energy held its stakeholder breakfast at Duane Morris. The event brought AEG’s stakeholder members together to discuss the topics of Smart Buildings and Grid Modernization.

Gregg Fischer, Director of Energy Systems at Tishman Speyer, talked about the important role thermal storage technology plays in managing 25 million square feet of the firm’s NYC real estate portfolio. He focused on Rockefeller Center in this installment of the AEG podcast, and efforts to retrofit landmark facilities with energy-saving technologies. The property was one of the earliest adopters of the now rapidly expanding thermal storage technology, which reduced electricity demand during peak periods and reduced operating costs. Mr. Fischer concluded by pointing out incentives can reduce investment payback periods from seven to thirteen years.
