This paper is based on field measurements in auditoria, carried out in Norway and in Switzerland. In both cases carbon dioxide (CO 2 was chosen as the relevant indicator to establish ventilation demand. Investigations in Norway focus on the aspects of airflow, patterns, ventilation efficiency and air quality. Intensive monitoring and numerical calculations with the computer code KAMELEON were performed. The Swiss project places more emphasis on impacts of demand control on energy consumption and occupant response. The results of the fild measurements, of the questioning of occupants, as well as of simulations which were carried out with the simulation code TRNSYS are presented. Results show that demand control with CO 2 , as indicator for ventilation demand can maintain an acceptable indoor climate while allowing substantial energy savings. These investigations were conducted as part of the IEA (International Energy Agency) research programme “Annex 18: Demand Controlled Ventilating Systems”.
