ASHRAE has funded two research projects to develop control sequences for VAV systems that meet Standard 62.1 Ventilation Rate Procedure requirements dynamically using CO2 and occupancy sensors while minimizing energy use. The first project (RP1547, completed in 2013) established the fundamentals of CO2 demand controlled ventilation and theoretical control logic to optimize energy performance. This seminar discusses the final results of the second project (RP-1747) which included developing detailed direct digital control logic that was then successfully validated with field tests and simulations.
