This analysis sought to understand the cost benefit of converting an existing commercial building’s HVAC system to three configurations of a Dedicated Outside Air System (DOAS) with each one increasing in energy efficiency. The analysis found the Very High Efficiency (VHE) DOAS package to have the highest net present value...
Dedicated outside air systems (DOAS) separate heating and cooling from the ventilation system to allow for optimal control of each of these critical building functions. Building on the DOAS concept, a very high efficiency DOAS includes heat recovery ventilation and focuses on increased equipment efficiency and optimized system design. This...
To better understand the potential non-energy benefits of very high efficiency DOAS, this literature review summarizes key research, empirical evidence, and studies performed on similar high-performance HVAC approaches, such as conventional DOAS.
