This comprehensive design guide includes the system definition and design recommendations that provide guidance to manufacturers, designers and specifiers regarding the key components of a Very High Efficiency Dedicated Outside Air System.
Dedicated outdoor air systems (DOAS) are a proven solution for reducing energy consumption as they optimize the control and functionality of ventilation and thermal comfort independently. A very high efficiency approach to DOAS pairs a high efficiency heat/energy recovery ventilator (HRV/ERV) with a high efficiency heat pump, while following design...
In commercial buildings across the U.S., outdated or inefficient HVAC systems waste a staggering amount of energy and money, while also creating unhealthy and uncomfortable indoor environments.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...
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.
