Getting the Most Out of DOAS: Energy Modeling Guidelines for Configuration and Verification

Join us for a Building Energy Simulation Forum (BESF) presentation on February 22 to learn more about very high-efficiency (VHE) dedicated outdoor air systems (DOAS). VHE DOAS is an optimized, high-performance approach to HVAC that significantly reduces energy use by combining high-efficiency equipment with design best practices. These findings have been supported from both field installations in the Northwest region and through detailed building energy modeling studies where models were refined to best represent how systems are configured and controlled. This session summarizes key recommendations from a recently published VHE DOAS energy modeling guidelines report. The session will further cover recommendations on how to:

  • Configure VHE DOAS components and equipment efficiencies
  • Setup default control sequences and setpoints
  • Better estimate building uses and constructions impacting thermal loads
  • Self-check your energy model through various methods
