Overview
New York City real estate investment manager Savanna wanted to improve energy efficiency and tenant experience at its One Court Square office tower, a green-tinted skyscraper with 53 floors that span almost 1.4 million square feet. A prominent fixture of the Queens skyline, One Court Square is one of the East Coast’s tallest buildings outside Manhattan.
With the help of Con Edison’s Commercial & Industrial Energy Efficiency Program and Non-Wires Solutions Adder Program, Savanna was able to get incentives to save over 80% of the project costs.
Working with Cushman & Wakefield, Smith Engineering, and Carrier Corp., Savanna retrofitted the components of the chiller plant serving the facility and installed a new building management system (BMS), which optimized the chilled water plant.
These upgrades helped Savanna save up to 20% in energy costs per year, increased its portfolio value, and modernized the building to comply with local laws and building codes. They also improved air quality, comfort, and environmental control for tenants.
