Mechanical HVAC

BNK Mechanical Engineering offers its expertise in HVAC and Building Automation design and energy modeling. These services have increasingly become critical elements in GREEN building design and certification. BNK’s mechanical engineering encompasses all aspects of Heating, Ventilation and Air Conditioning design, ranging from packaged systems – such as high efficiency heat pumps, variable refrigerant flow, and energy recovery ventilators – to complex systems using built-up air handling units, magnetic bearing chillers, condensing boilers, and cooling towers. Our services include feasibility studies, preliminary design, preparation of construction plans and specifications, construction management, and contract administration. These services are offered to architects, building owners, industry, and contractors. Our projects include high rise construction, sports facilities, hospitality, and large research buildings for universities.

Building system need upgrades? We provide design services for the evaluation and replacement of building components such as fans, pumps, chillers, boilers, cooling towers, and packaged HVAC equipment. Our diagnostic capabilities include air flow studies for determining building air distribution and pressurization problems.
