Maximizing Heat Recovery in DOAS: Best Practices for Energy Modeling of High-Efficiency Systems

This presentation explored advanced energy modeling strategies for Very High Efficiency Dedicated Outdoor Air Systems (VHE DOAS). VHE DOAS systems enable significant reductions in energy consumption compared to conventional mixed-use HVAC systems. The presentation shares modeling insights, field studies, and case examples drawn from calibrated studies of DOAS configurations across various building types and climate zones.
