Many air handling units supply a volume of fresh air into a building at a constant rate and consume a considerable portion of the building energy. This rate was determined during the design stage originally to provide enough fresh air per person and to deal with a number of other environmental factors. Perhaps it is time to reassess this set-up and take advantage of energy saving opportunities.

Demand based Ventilation either counts the number of people in an area or measures the CO2 level and adjusts the supply and extract fan motor speeds. Our guest speaker Chris Mulholland from Critical Airflow is presenting the Aircuity solution along with data and case studies from a number of projects.
