Application of an occupant voting system for continuous occupant feedback on thermal and indoor air quality – Case studies in office spaces

Smartphone applications or electronic devices in the form of occupant voting systems (OVS) have demonstrated to be feasible for acquiring feedback from occupants support building operation manager identify indoor environmental quality (IEQ) problems and inappropriate control settings heating, ventilation air-conditioning (HVAC). The present paper aims contribute growing research on OVS as a tool management. presents study about tangible OVS, denoted TiAQ, that could use vote their here-and-now experiences regarding thermal environment air quality. main objectives were whether there was an alignment between votes collected with TiAQ monitored IEQ variables well demonstrate problematic conditions appropriate strategies HVAC control. related variations temperature airflow. Additionally, i.a. poorly set setpoint reduce energy by 46% increase comfort cold complaints 6% if current airflow lowered.
