Very High Efficiency Dedicated Outside Air System Pilot Project Summary Report
As a result of the scanning of emerging technologies in the commercial building sector, a dedicated outside air system (DOAS) was identified as an effective strategy for significant energy savings potential in the Northwest. This report details the findings from eight pilot projects conducted in partnership with local utilities and energy efficiency program partners. These pilots tested a DOAS approach that included dedicated ventilation air (decoupled from primary heating and cooling air) with high-efficiency heat recovery and a high-efficiency heating and cooling system. This equipment was coupled with key design principles to maximize system performance. The pilot projects, conducted on mostly small-to-medium-sized buildings, helped validate energy savings assumptions and gain a better understanding of the design and installation process.
