PB's full-service capabilities include all aspects of mechanical, HVAC and building ventilation for commercial, industrial, institutional and transportation facilities.

We specialize in designing central power plants (electric, thermal and cogeneration), building HVAC systems, energy conservation studies, alternative energy sources, computerized building management systems, building envelop energy analysis and waste heat recovery systems.

Our engineering services range from system modification and upgrading, flow calibration, heat loss analysis, weatherproofing, system commissioning, testing, debugging and construction management.

In addition to the traditional ventilation system expertise, PB brings a unique capability in the modeling of smoke and fire migration within enclosed spaces, using advance computational fluid dynamic codes; this capability is currently being expanded for deliberate toxic gas discharges associated with environmental terrorism.
