To better understand the potential non-energy benefits of advanced performance dedicated outside air systems (DOAS)—previously known as very high efficiency DOAS, this literature review summarizes key research, empirical evidence, and studies performed on similar high-performance HVAC approaches that are more prevalent in today’s market, such as conventional DOAS.

As advanced performance DOAS improves upon high-performance HVAC approaches used by conventional DOAS, the non-energy benefits summarized in this report can be assumed to manifest to an equal or greater degree with an advanced performance DOAS approach.
