In commercial buildings across the U.S., outdated or inefficient HVAC systems waste a staggering amount of energy and money, while also creating unhealthy and uncomfortable indoor environments. However, research and field studies have proven there’s an optimal approach to HVAC design that can significantly improve indoor air quality and occupant...
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...
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.
