It is operated by NYC Health + Hospitals, a public benefit corporation of the city.


New York Power Authority and Guth DeConzo engaged a contractor to perform a design build for upgrades to the domestic water system and to utilize the by-product of a heat pump to supplement the cooling for the existing data center located in the basement of the N building. Interstate mechanical teamed up with DM Engineers to develop and built this energy saving driven project.

The intent of this project will be to install two (2) heat pump domestic hot water heaters (along with all associated equipment, piping and accessories) in the mechanical room located in the basement of N Building. Previously, the domestic hot water in N Building was served by two (2) existing 1,000 Gallon storage tanks with internal steam coils. The new heat pump system will remove the need to utilize steam coil and instead heat the water utilizing a heat pump. These heat pump hot water heaters were provided with OEM plenum fans, so that they can be used to supply cold air to the data center located next to mechanical room, for supplemental cooling.

New return and discharge ducts and associated diverting dampers were provided to achieve the desired supplemental
cooling operation

Brookdale Hospital Medical Center

DM Engineers PLLC, in partnership with Environmental Engineering Solutions, is currently undergoing a feasibility study to complete the installation of the two new vapor absorption chillers located on the 98th street side of campus. Currently, the primary source for chilled water on campus is a steam-driven absorption chiller rated at 1800 Ton of cooling capacity.

The main intent of this project is to enable the new two 940 Ton Vapor absorption chillers to function as the primary cooling source of the campus, provide means to establish the existing 1800 Ton chiller as the n+1 redundancy for the hospital and to allow for economizer “free cooling” for this equipment via a plate a frame heat exchanger. Our team will assess the condition of the equipment, engineering requirements to connect the equipment and provide an opinion of probable cost for the execution of the construction.

Interfaith Medical Center

Interfaith Medical Center intends to renovate the 2nd floor, 3rd floor, and 4th floor in the Main Building as part of the overall transformation effort of One Brooklyn Health System. The plan is to gut renovate the second floor and refurbish the other floors to upgrade the M/S patient bed units (approximately 81).

In addition to create a renewed in-patient unit, the goal is to increase intensive care unit (ICU) bed count, allow for ICU overflow in the event of surge needs, and incorporate single beds into the bed count. One key objective is to upgrade all mechanical, electrical, plumbing, fire protection, IT, and security infrastructure to meet current building codes. The construction of the project will be phased in such a way that the M/S unit can remain operational for the duration of the buildout.

DM Engineers in partnership with Cosentini Engineers developed the design for the MEP displines for this project. Specifically DM performed the electrical, fire alarm and IT design from schematic thru construction documents.
