# Effect of Exposure Time on Thermal Behaviour: A Psychophysiological Approach
## 3 Experimental Set-Up  
The experimental dataset presented in this paper was collected over 6 weeks, from five volunteers. Two of the subjects (participant 2 and 4) had to come in on the 7 th week since they each missed one appointment during the original 6-week period. Experiments started on 10 May 2021 and data collection was concluded on 28 June. The experiment took place in Munich, in the Faculty of Architecture of the Technical University of Munich. The experiment was designed and conducted according to the ethical codes of the University. All five subjects participating in the experiment were healthy individuals, aged between 24 and 37. Prior to the start of the data collection period, each participant was asked to pick one day of the week to join the experiment, and they came in every week the same day so that their respective schedule structures and type of work over the course of 6 weeks would be similar and comparable to their data from other weeks. The participants' daily schedules were also kept the same and each participant decided when they would like to start and finish the workday, in order to simulate their normal work experience as much as possible. Each participant spent a total of 7 h in the experiment space each day, of which 6 h were (suggested having been) dedicated for working and 1 h for a lunch break. Additional breaks were all considered in the working hours. All participants worked on their personal laptops, on their day-to-day tasks. Table 1 shows further information for each subject. Figure 2: Tonic and phasic component of EDA. The experiment was carried out in an open plan studio space--Clima Lab. The Clima Lab is a 250 m\({}^{2}\), free running space with a ceiling height of 7 m and a facade orientation to the south-east. While the Clima Lab is occasionally used as test space, it functions as a regular open space office containing several desks, a lounge area, a kitchen and a bathroom. The Sense Lab is a climate chamber within the Clima Lab and located on one end of the space (see Figure 3). Sense Lab is a remotely controllable climate chamber built inside the space. The room surrounding the lab is an actual workspace and is used by a minimum of two (the authors) and a maximum of eight people during the week. The experiment was designed to be in a semi-lab, semi-real-world environment, therefore, the access to the space by other people working there was not restrained. \begin{table}

During the data collection, the air temperature inside the open space measured 24.22 \(\pm\) 1.82 \({}^{\circ}\)C, with an overall minus delta of 3.85 \(\pm\) 2.10 K from the air temperature inside the Sense Lab (see Table 2).
