Project Description

HEA is the commissioning authority for the World Trade Center Memorial Fountains, Memorial Museum & Pavilion project. The $800 million facility was created to commemorate the events of 9/11. HEA is providing comprehensive mechanical, electrical, plumbing, security, vertical transport, closed circuit TV and fire protection commissioning services for the new 190,000 sf facility. HEA is satisfying the requirements for the NY State Executive Order 111, Sustainable Guidelines for the WTC Redevelopment Projects, LEED NC: Energy and Atmosphere (EA) Prerequisite 1: Fundamental Commissioning of the Building Energy Systems and EA Credit 3: Enhanced Commissioning. In addition to commissioning, HEA is providing mechanical, electrical and plumbing coordination services and support.

At the very heart of the Memorial, inscribed on bronze parapets surrounding the twin Fountains are the names of nearly 3,000 men, women and children that were killed in the attacks of September 11, 2001 and February 26, 1993. The two 800 foot-long parapets have both heating and cooling systems to ensure the public can see and touch the names at all times. The unique cooling system, required due to the bronze parapets heating up in excess of 160 degrees during the summer months, provides over 200- tons of cooling capability to each of the parapets. HEA commissioned and participated in the redesigning and implementation of both parapet systems. HEA redesigned the design build system by realigning the system piping so it would no longer be visible when viewing the names. HEA encountered many challenges throughout the redesign most notably with the flex stainless steel piping. HEA had to design the piping so when they were rigged for installation each 3,000 lb panel would not damage the flex hoses, and then align without damaging the hoses that passed through the mounting flange into the below tunnel where they connected to the headers for the systems.

The project is composed of three elements: a ground level plaza with waterfalls at the site of the fallen towers, the below ground level Memorial Museum of approximately 150,000 sf and the above ground level Museum Pavilion. The Museum Pavilion serves as the visitor’s entryway to the Memorial and Memorial Museum. This building includes museum ticketing, security check-in similar to airports, an auditorium and café. Mechanical commissioning includes an emergency chiller, vertical transportation and a generator shared with the Memorial. The Museum Pavilion obtains its electrical power from the Memorial and its primary chilled water supply comes from the central chiller plant constructed by the Port Authority of NY and NJ.

Project Description

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. 

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

Project Description

HEA was contracted by Kings & Queens Maintenance Services to provide Local Law 87 (LL87) energy audit and retro-commissioning services for the Dumont Hotel renovation project, located at 150 East 34th Street in New York, New York. As per the requirements of Local Law 87 of 2009, the objective of the project was to assess and benchmark the building’s current energy use and to reduce the building’s overall energy consumption. 

During the energy audit and retro-commissioning process, HEA found that domestic hot water was being created using steam that required the boiler to run during the summer. With a conversion to gas, energy savings will be realized by reduction of oil usage by steam boilers and increased efficiency of new domestic hot waters. The building’s pressure control settings were also not coordinated correctly, causing the boiler to maintain a steam pressure between 6-8 PSI. By lowering this steam pressure, the building was able to save energy by reducing standby losses. Finally, it was found that controls on the roof top and lobby unit were not operational and were causing thermal comfort issues and excess energy usage. HEA helped to address all of these deficiencies to help ensure the building was running as energy-efficiently as possible.

Project Description

Redford Township contracted HEA to retro-commission the mechanical equipment, controls system and perform an air balancing verification report for the Redford Township Library. The systems and equipment tested included: the heating hot water system and piping (boiler, pumps and reheat coils), the domestic water system and piping (domestic hot water heaters, domestic hot water tank and associated pumps), and the air conditioning and ventilation systems (air handling units, air cooled condensers, humidifiers, fan powered boxes, VAV boxes, unit heaters, cabinet heaters, finned tubes and exhaust fans). All automated control sequences for the equipment above were reviewed through the Building Management System (BMS) as well.

The project was able to bring forward issues that were not addressed at the time of the library's turn over to the owner. In doing so, the library is now able to run more efficiently and reduce the time maintenance spends on the maintaining and operating of the library. An example of this was the issue with AHU-2 running continuously during after hours due to a low ambient room condition. It was found that a fan powered box that serves a section of the future children's library had some internal insulation fall into the unit, therefore preventing appropriate ventilation and heating to the space. After resolving this issue, the space was able to maintain temperature during after hours and provide energy savings. All deficient items found during the commissioning process were documented and corrected to optimize building efficiency and improve the comfort of the occupants. As a result of the commissioning, HEA has estimated the savings for Redford Library to be approximately $5,600 per year.
