Mount Sinai Brooklyn

Mount Sinai Brooklyn

The healthcare sector in the United States is under unprecedented pressure to accomplish more with less. The management at Mount Sinai Brooklyn decided to find creative ways to reduce the hospital’s operating costs, improve the patient care experience, and reduce its environmental footprint by upgrading its energy infrastructures.

While the hospital’s energy consumption could have been reduced by simply installing high-performance electromechanical equipment, Ecosystem’s engineers dug deeper to find innovative measures to substantially reduce energy costs. The project featured the installation of a combined heat and power plant to generate electricity on site, improving the hospital’s resiliency by reducing dependency on electrical utilities by 40%. Energy use was greatly reduced with a steam to hot water conversion and an upgrade of the hospital’s heating plant.

Ecosystem and Mount Sinai Brooklyn’s collaborative effort was awarded Energy Project of the Year in 2013 and 2014 by the Association of Energy Engineers.

Combined heat and power systems, though still relatively rare, are gaining popularity in markets with high electricity costs. In certain cases, these systems can even provide complete energy independence from the grid.


Energy Project of the Year award from the Association of Energy Engineers for two consecutive years: 2013 (New York Chapter) and 2014 (USA, Region 1)

2015 EBie “All-Rounder” Award from the New York chapter of the US Green Building Council, recognizing the most improved building across multiple sustainability categories.

Customized Performance Measures

Combined Heat and Power (CHP)

Onsite gas-fueled power plant that generates both electricity and heat for a lower cost and with higher efficiency than energy available from the grid, leading to greater resiliency and energy independence.

Steam to Hot Water Conversion

Conversion of the heating system from a steam system—which is energy intensive and subject to leaks—to a hot water system, which uses less energy to reach the required temperature.


Replacement of older generation bulbs and fluorescent tubes by T8 tubes, which are more efficient and provide better lighting quality.


Upgrade of ventilation system to efficiently deliver warm and cool air where it is most needed, and maintain appropriate levels of fresh air.

 Centralized Controls

Upgrade of Building Automation System in order to maintain occupant comfort and better manage energy consumption.
