DOAS with ERVs

Getting to Know DOAS with ERV Systems


Dedicated Outdoor Air Systems (DOAS) and Energy Recovery Ventilators (ERVs) provide controlled and conditioned ventilation that improves indoor air quality and occupant health, while reducing greenhouse gas emissions and saving energy. how do DOAS with ERV systems work?


All commercial buildings are required to supply fresh air to occupied spaces. Fresh, clean air supports human health and is critical to indoor air quality and comfort. Although ventilation methods may differ, tempering incoming fresh air to meet indoor heating and cooling needs is typically an energy-intensive process.


A Dedicated Outdoor Air System (DOAS) with a energy efficient Energy Recovery Ventilator (ERV) is a high-performance ventilation system design that can significantly reduce a building's heating and cooling loads.


Conventional heating, ventilation, and air conditioning (HVAC) systems must fully temper fresh air before distributing it throughout a building. This contributes to high heating and cooling loads, and means that fresh air is only provided simultaneously with space heating or cooling. A DOAS, on the other hand, brings fresh air into interior spaces independently from heating and cooling, greatly increasing efficiency and allowing the downsizing of HVAC equipment.
