Energy Project of the Year: U.S.
Mount Sinai Hospital RTEM

Mount Sinai Health System. Mount Sinai Medical Center, New York.

Mount Sinai Hospital installed the Aciex Real-Time Energy Management (RTEM) platform to effectively manage peak power demands through advanced feedback-control technology. This fail-safe system, equipped with intelligent state-of-the-art microelectronics, measures and regulates power demands in real time. By gradually adjusting power to individual loads such as air handling units (AHUs), fans, motors, and pumps, the platform avoids the harmful effects of on-off demand controllers and ensures that the facility’s aggregate power demand remains below the desired threshold based on live energy data and user priorities. It automatically monitors and controls loads without compromising building comfort. The system mitigates expensive demand peaks while maintaining operations, ensuring energy savings. The platform also includes a visualization graphics module for real-time tracking and archiving of demand and energy consumption. This feature helps detect and correct anomalies, contributing to significant energy savings and making real-time grid response a strategic tool for energy management.

Historically, Mount Sinai’s 2 million square foot facility managed peak loads manually through load shifting, but this approach was neither sustainable nor effective. The hospital sought a higher level of automation for peak load management and aimed to generate additional revenue by participating in Demand Response (DR) programs to offset high utility costs. Additionally, the hospital needed to comply with New York City’s Local Law 97 (LL97), which targets carbon footprint reduction. It integrates seamlessly with the Building Automation System (BAS), communicating via BACnet to manage demand reduction efficiently. The new RTEM platform allows savings of 1,098 kW per year, 2,155,525 kWh kW per year CO2 equivalent, 3,367,744 lbs. annually. The annual projected DR Revenue is $162,908 and the annually projected cost savings is $382,339. This project was recognized as the NY-AEE Chapter’s 2022 Energy Project of the Year award.
