Description

A combination of dedicated outdoor air system with very high efficiency heat recovery ventilator (>80%), and high efficiency variable-capacity heat pump,  VRF, or hydronic radiant system. Key distinguishing feature is the separation of ventilation from heating and cooling via a Dedicated Outside Air System (DOAS) with air tempering by a very high efficiency heat recovery ventilation system. Applicable in new construction and existing renovations, and replacement of packaged rooftop units.
