• Princeton University Neuroscience Building

    D&B Engineering designed a solution that was able to meet very strict fan efficiency and sound requirements in this state-of-the-art building. D&B designed and configured units incorporating all of the university's sound, performance, and laboratory requirements. These units include exceptionally efficient multiple fan arrays, 4" perforated sound walls, integral and bypass steam coils, energy recovery wheels, energy recovery coils, and double-jacketed humidifiers.View More

  • Colgate Palmolive

    D&B provided magnetic-bearing water-cooled chillers, condenser water pumps, and variable frequency drives to replace Colgate-Palmolive’s outdated, energy consuming HVAC equipment. Colgate-Palmolive’s annual energy savings totaled $283,898 and D&B assisted them in receiving a $224,526 incentive from New Jersey’s Clean Energy Program.View More

  • Immaculate Heart Academy

    Immaculate Heart Academy is a prominent all girls private school in Washington Township, NJ.

    The boiler plant in the school dated back to the 1950’s with one of the boilers completely inoperable thereby leaving the school limping along on the remaining boiler which had no back-up. This condition persisted through the 2011 -2012 winter season

  • Mack Cali

    D&B Engineering provided replacement equipment that met the very tight roof space restrictions. We were able to utilize McQuay Skyline “variable aspect ratio” rooftop units with custom duct opening to fit and eliminate the need for costly adapter curbs, roof steel, or duct transitions.

 Princeton University Neuroscience Building
D&B Engineering designed a solution that was able to meet very strict fan efficiency and sound requirements in this state-of-the-art building. D&B designed and configured units incorporating all of the university's sound, performance, and laboratory requirements. These units include exceptionally efficient multiple fan arrays, 4" perforated sound walls, integral and bypass steam coils, energy recovery wheels, energy recovery coils, and double-jacketed humidifiers. The 4"-thick double-seal access doors provided extremely low leakage at high static pressures

Immaculate Heart Academy is a prominent all-girls private school in Washington Township, NJ. The institution's boiler plant in the school dated back to the 1950s with one boiler completely inoperable thereby leaving the school limping along on the remaining boiler without back-up. As a turnkey solution, D&B Engineering replaced 5500 MBH of old Cleaver Brooks boilers with three Fulton 2000 MBH condensing boilers. The new boilers operate at efficiencies near 97%, while the old boilers struggled to achieve 60% efficiency.


 Mack Cali


D&B Engineering provided replacement HVAC equipment that met the extremely tight roof space restrictions at Mack Cali corporate headquarters. D&B was able to utilize Daikin Skyline “variable aspect ratio” rooftop units with custom duct openings to fit and eliminate the need for costly adapter curbs, roof steel, or duct transitions. The Daikin Skyline rooftop units are both airtight and weather tight.  Easy design and specification, economical installation, and low cost maintenance for the life of the Skyline units make this and ideal equipment choice.
