SEMINAR 19: Not Too Little, Not Too Much, Just Right: ASHRAE Standard 62.1 Demand Controlled Ventilation and RP-1747

Date: Sunday January 13, 2019

Location: GWCC, 3rd Floor, Building A, A305

Track: The Convergence of Comfort, IAQ, and Energy Efficiency Building
Sponsor: 4.3 Ventilation Requirements and Infiltration
Chair: Steve Taylor, P.E.

Summary: 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.

Attend a Committee Meeting

ALL ASHRAE committee meetings, including this TC’s meetings at the Winter and Annual Society conferences, are open to the public at no cost nor is conference registration required. Interested visitors, local chapter members, and potential new TC members are always welcome. However to attend technical program sessions sponsored by the TC will require registration and payment of any applicable fee.

Participation in an ASHRAE TC provides the opportunity to grow professionally and to contribute to the advancement of HVAC&R within an international organization recognized for shaping the future of the built environment through research, standards writing, publishing, and education.
