Project – New York City Police Academy
This project is part of the New York City Police Department’s (NYPD) construction of a new Police Academy in an effort to incorporate many of the NYPD’s existing training facilities throughout New York City into one 32-acre campus. This project is part of the development of a modern academic and physical training complex for recruits, civilians and active police officers that are currently spread across the city. The 32-acre campus, operated by the NYPD Training Bureau, opened its doors in 2014, consolidating the old Police Academy in Manhattan and existing training facilities throughout the city into one central location. The new facility has nearly three times the amount of useable space as the old academy and features modern classrooms, a gymnasium and indoor track, and a tactical village that emphasizes hands-on scenario-based training. Mock-environment training rooms include a precinct station house, multi-family residence, grocery store, restaurant, park, court room, bank, and a subway car and platform
Project – United Nations Headquarters, Capital Master Plan
The United Nations (UN) complex spans over 17 acres and includes six buildings totaling 2.7 million sf. The original structures were built in 1950. Because the UN’s problems were associated with aging building systems, and not the basic construction, a renovation of the complex was the most cost-effective way of replacing the inefficient equipment.

Because the UN’s problems were associated with aging building systems, and not the basic construction, a renovation of the complex was the most cost-effective way of replacing the inefficient equipment.
HEA was hired to provide commissioning services for the renovation project. Although the project did not obtain LEED certification, it followed the same standards set forth by the USGBC. HEA’s scope of work encompassed the mechanical, electrical, plumbing, vertical transport, BMS and fire safety systems. The renovation was performed while the complex remained in operation so in order to minimize disruptions to employees and the General Assembly, all team members completed the project in phases following alongside a very tight construction schedule. Because of the continual design changes to the complex, HEA remained flexible in altering and updating documentation to meet the project’s needs.
A unique feature of this project centered around the UN’s chiller plant. The plant utilizes condenser water by two methods: a river water system and a cooling tower condenser water system. If the river water is 50 degrees or below, the river water system is used. If the temperature is above 50 degrees, plate and frame heat exchangers are used to isolate the river water mixing with cooling tower condenser water and to generate secondary cooling tower condenser water supply. Under normal operation, river water is used directly as condenser water, utilizing a water side economizer mode.
HEA identified numerous deficiencies throughout the complex including:
- Sensors out of calibration
- Insufficient access for maintenance staff of the air handling units
- Fire smoke dampers were missing
- Poor controls and BMS interface
- Supply chilled water piping was piped to coil return, and return chilled water piping was piped to coil supply
