NJ State Police Barracks
Newark, Bloomfield, Galloway, & Moorestown, NJ
The New Jersey Turnpike Authority has replaced four state police facilities built to LEED standards.
The buildings were designed as prototypical facilities alongside Gannet Fleming, but were flexible so that they may be adapted to each site location.
M&E evaluated a variety of HVAC approaches and is implementing the Commissioning Process for the energy commissioning systems.
The mechanical systems included two basement air handlers with energy recovery, five packaged rooftop units (two with energy recovery), a gas-fired condensing boiler, and air distributed through a combination of variable-air-volume (VAV) boxes and constant volume systems.
Somerset County Administrative Building
Somerville, New Jersey
M&E performed a Level 2 Energy Audit, including energy modeling.
An analysis revealed that although upgrades had been performed on the lighting and HVAC systems, including an integrated Building Management System, the building was still only performing in the 32nd percentile according to Energy Star.
A more detailed analysis was done to uncover the root cause of the poor performance. Various approaches were analyzed, including conversion to high efficiency frictionless chillers and ice storage.
M&E designed comprehensive system upgrades and replacements, and provided construction administration and commissioning services.
Hunterdon Developmental Center
Clinton, New Jersey
The facility houses approximately 600 developmentally challenged individuals and is manned 24/7.
Two Trane absorption chillers and one cooling tower were replaced with an energy efficient electric chiller system powered by the cogeneration plant at the neighboring Edna Mahon Correctional Facility.
M&E compared nine different chiller approaches to the existing system and performed a design for two 500 ton air-cooled chillers, which resulted in a annual savings of $225,823 representing a 49% savings in operating costs.
NOAA Marine Laboratory
Sandy Hook, New Jersey
Replacement of two existing oil fired boilers for process water heating. The existing boilers were no longer manufactured.
Due to tight space constraints, vertical boilers were installed as the replacements.
A new variable speed draft inducer system was installed on the chimney. The existing chimney serves five heating appliances (four boilers and one hot water heater). The system was designed so that any one appliance could fire while still maintaining an adequate draft for each unit.
Boilers are being used to heat water for various fish tanks.
