Very high efficiency dedicated outdoor air systems (very high efficiency DOAS) are a proven solution for reducing energy consumption as they optimize the control and functionality of ventilation and thermal comfort independently. This very high efficiency approach is comprised of four key elements: high efficiency heat/energy recovery ventilator (HRV/ERV), a high-performance electric heat pump system that meets or exceeds current ENERGY STAR® minimum efficiency requirements, fully decoupled ventilation from the heating and cooling equipment, and a right-sized heating and cooling system.
Addressing the heating and cooling needs of a building, and applying best practices in design on a project-by-project basis, enables maximum performance and substantial energy savings. But did you know there are non-energy benefits of applying this approach to HVAC in commercial buildings that are also important?
