Washington State University’s Shelby Ruiz breaks down a commercial building HVAC design approach that can help designers exceed Washington State Energy Code while reducing viral risk and improving thermal comfort and indoor air quality. Hear from Ruiz as she details the very high efficiency DOAS approach to HVAC design and...
While conventional practice can lead to HVAC systems that are oversized by 25% or more, the proven very high efficiency approach to DOAS design allows for the downsizing of heating and cooling systems through ventilation heat recovery and by decoupling ventilation from the primary heating and cooling equipment. In fact...
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...
This energy modeling guide for energy analysts and design consultants addresses a resource gap for best representing very high efficiency DOAS in annual energy modeling by providing technical analysis support and recommendations using lessons learned and time-tested methods.
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...
