Mechanical Engineering

N3D Group designs HVAC systems that best meet the Owner's and Building's specific needs. We evaluate many criteria before selecting a system for any facility - new or renovation. Not only does the system have to be energy efficient, but the system must be easy to maintain and easy to control after it is left with the Owner. N3D is always available after a construction project to assist with operating a HVAC system.

N3D further uses building energy modeling to assist in life cycle decisions between equipment, systems and building material selection process. Architects are encouraged to use our life cycle cost modeling to make decisions on what types of windows, roofs, wall insulation and building orientation to use. 

N3D wants to leave systems in good working order and with a well-trained Owner that is very comfortable with how to keep the HVAC system operating at top performance. N3D routinely reviews buildings throughout their warranty period and many years beyond to make sure the systems are working per design.
