Very high efficiency dedicated outside air systems (very high efficiency DOAS) pair the highest performance HVAC equipment with key design principles to provide cleaner and safer indoor air, enhance indoor comfort, and reduce commercial building HVAC energy use. This approach has been demonstrated to reduce HVAC energy use by an...
For building owners and operators everywhere, the COVID-19 pandemic has magnified the importance of enhancing indoor air quality through better approaches to commercial HVAC and natural ventilation. A recent study conducted by the Northwest Energy Efficiency Alliance (NEEA), Red Car Analytics (RCA) and the University of Oregon (UO) proves how...
This report summarizes the findings of a study conducted by Red Car Analytics on behalf of the Northwest Energy Efficiency Alliance (NEEA) to determine the potential for direct-expansion air conditioning dedicated outdoor air systems (DX-DOAS) products in commercial buildings.
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.
