Modeling approaches for calculating cost-effectiveness of Dedicated Outside Air Systems
We’re excited to announce our next BESF session in December, focusing on the advanced tools and approaches used to accurately model Very High-Efficiency Dedicated Outside Air Systems (VHE DOAS).
These systems improve the overall efficiency of the DOAS concept by pairing a high-performance heating and cooling system (such as a heat pump or variable refrigerant flow) with a heat recovery ventilator or energy recovery ventilator and an optimized system design.
Analysis from five pilot demonstration sites in the Pacific Northwest shows an average of over 40% whole-building energy savings and over 60% HVAC savings compared to code minimum replacement of the existing equipment.
Current modeling tools require extra attention to more accurately model these systems. This session will cover advanced modeling approaches with a brief overview of results using OpenStudio and EnergyPlus for calculating the cost-effectiveness of VHE DOAS relative to other DOAS systems.
