CO2 Monitoring for Outdoor Airflow and Demand-Controlled Ventilation
Join us for our January ASHRAE Chapter Meeting!
About the subject:
A number of programs and standards that exist for buildings today specify the use of outdoor air monitoring. Monitoring is to be done either based on CO2 levels in the occupied space or actual measurement of outdoor airflow, depending on the space design occupancy and ventilation type (mechanical or natural). Current standards or program descriptions do not provide detailed guidance for determining what level of CO2 should be considered the maximum concentration to expect, and those that do provide guidance are generally based on a single value above the ambient concentration. This session describes how to determine a level for CO2 concentrations for an outdoor airflow monitoring program or as part of the upper control limit for a demand-controlled ventilation system.
