“…Based on previous research (Mathur et al, 2015) and literature reviews on OVS (Jung and Jazizadeh, 2019;Sheikh Khan et al, 2020) the authors identified the following three main characteristics, "non-intrusive, " "accessible" and "simple, " to guide the design of TiAQ for use in office spaces. First, it was important that the OVS was non-intrusive and did not act as a stressful and disturbing factor in the occupants' daily activities.…”

“…The responses submitted with the OVS can be timestamped and related to contextual factors such as indoor environmental measurements (Konis, 2013;Guerra-Santin and Tweed, 2015;Carre and Williamson, 2018;Geng et al, 2019). OVS is designed to "continuously" collect feedback on occupants' perception of IEQ (Sheikh Khan et al, 2020). Various applications of OVS (e.g., for indoor temperature control or POE) have been studied.…”

“…However, some prevailing limitations were identified in existing research studies on OVS. First, very few studies were identified (e.g., Lassen et al, 2020) that evaluated the reliability of occupant votes (Lee and Karava, 2020;Sheikh Khan et al, 2020). Second, most studies used smartphone apps (e.g., Winkler et al, 2016) without considering other alternatives of user interfaces (Lee and Karava, 2020;Sheikh Khan et al, 2020) and how that might affect the collected occupant votes.…”

But this is neither necessarily viable nor representative in case of real-life settings where the objective is to integrate the OVS as part of building operation management.…”

Occupants can provide valuable feedback on the indoor environmental quality of buildings. Research on occupant voting systems (OVS) has demonstrated that apps or electronic devices can act as viable tools for collecting long-term feedback from occupants. However, previous research has only to a limited extent explored occupants’ interaction with OVS and the impact it might have on the reliability of the collected feedback. The present paper presents three case studies on applying a tangible OVS, denoted TiAQ, to collect feedback on thermal and indoor air quality (IAQ) in office spaces. The main objective of the present study was first to explore occupants’ interaction with TiAQ and their motivation. Second, identifying whether feedback collected with TiAQ could represent occupants’ comfort and discomfort with the thermal environment and IAQ. Thirdly, identifying challenges related to occupants’ interaction with TiAQ that might affect the representativeness of collected feedback. The present study was conducted at three office buildings in up to 7 months and demonstrated that TiAQ was suitable for collecting long-term feedback on occupants’ comfort and discomfort with the thermal environment. On average, one vote was cast per day per occupant. Additionally, in one of the office buildings, 60% of occupants reported to have interacted with TiAQ daily or weekly when, e.g., passing the device going to/from the office spaces. Occupants’ expectations of TiAQ and getting “feedback on feedback” need to be further addressed to identify ways to sustain occupants’ long-term use of the device and reduce “ill-willed” interactions.
