Human-Window Interaction in open-plan workplaces: Guiding occupants to efficient window operation through window feedback systems

Occupants are often unaware of window-opening strategies that can enhance their well-being and reduce energy consumption. Window feedback systems that indicate when to manually operate a window have become a strategy for enhancing the indoor climate, occupant satisfaction and energy efficiency. These systems are recognised for providing the comfort benefits of manual window controls while providing the efficiency benefits of completely automated windows. However, there is a lack of evidence as to what extent window feedback systems are able to guide occupants towards effective window operation for both energy and comfort.
This research proposes a new window feedback system based on indoor air quality, thermal quality and energy performance. Preliminary testing and deployment of the system in an open-plan workplace show improved indoor temperature, relative humidity and CO2 concentration. Furthermore, results show increased occupant satisfaction with the indoor environment and a reduced ineffective window opening time of 55%.
