This study compared decoupled air conditioning systems using direct-expansion air conditioning dedicated outdoor air systems (DX-DOAS) with others utilizing ERV/HRV-DOAS. The project included an energy analysis of typical commercial buildings using two types of DOAS—DX-DOAS and Washington state code minimum ERV/HRV-DOAS—while keeping the space conditioning system equal.

This report summarizes the leading institutions’ COVID-19 mitigation recommendations for commercial ventilation systems, including:

1. Evaluates a COVID-19 mitigation strategy of increasing a building’s outdoor air by utilizing mechanical ventilation to reduce viral transmission risk.
   2. Evaluates how increasing outdoor air as a strategy impacts the operational energy costs for three types of heating, ventilation and air-conditioning (HVAC) systems, a Very High Efficiency Dedicated Outdoor Air System and two types of conventional mixed-air systems; packaged single zone variable air volume systems and a packaged multi-zone system.
   3. Reviews the resiliency benefits of a Very High Efficiency DOAS system in building operations.

The purpose of this report was to identify the cost benefits of converting a commercial building’s HVAC system to three configurations of a Dedicated Outside Air System (DOAS) with each one increasing in energy efficiency. The findings showed that a Very High Efficiency (VHE) DOAS package has the highest net present value over the estimated life of the equipment, 20 years, in all climate zones and building types analyzed.
