Unveiling the role of deployment in the performance of ASHRAE Guideline 36

This paper presents a simulation-based assessment on how the deployment of ASHRAE Guideline 36: High-Performance Sequences of Operation for HVAC (G36) impacts the energy performance of G36.In this assessment, an EnergyPlus model and a control sequence in G36 are co-simulated.This EnergyPlus model represents a variable air volume system that serves Oak Ridge National Laboratory's Flexible Research Platform 2 Building.When performing the assessment, we consider six cases, to represent various deployments.In Case 1 and 2, ideal and poor local control loops (LCLs) are considered, respectively.In Case 3 and 4, ideal LCLs with positive and negative sensor bias are considered, respectively.In Case 5 and 6, poor LCLs with positive and negative sensor bias are considered, respectively.Those assessment results suggests 1 C sensor bias leads to 2.5 time changes in the energy savings from G36.They also reveal that the control performance of LCL result in 2.3 time differences in the peak power.
