Table 2: Correlations between perceived control with exercise control and perceived comfort. Figure 6: Self-reported productivity in comparison with perceived comfort and control of the IEQ parameters. In the last part of the questionnaire, participants expressed their degree of acceptance of the lockdown aspects due to the pandemic, and the results are presented in Table 3. In general, office occupants agreed to the applied polices and they seemed to accept the new conditions in their offices (mean score above the neutral score 3). On the other hand, at the time of the survey, they reported that they do not prefer to work from their homes anymore (score 2.54). The acceptance of new working conditions and the aspect of how the rest of the occupants in their office accept them, showed significant statistical correlation with their overall comfort (Spearman cor. 0.185, \(p\) < 0.01 and 0.370 \(p\) < 0.01). The occupants' acceptance of the COVID-19 countermeasures application, in order to ensure a healthy and safe environment at work, was significantly correlated to all overall IEQ parameters. Similar results were revealed as to whether participants believed that their colleagues considered the COVID-19 situation to be serious. These new findings were also reported in a study conducted in offices in Japan during the pandemic period, where it was highlighted that increasing satisfaction with COVID-19 countermeasures may increase occupants' performance in the offices [7]. Higher acceptance levels of the parameters, such as feeling comfortable in returning to workplace and the application of systems for social distancing and COVID-19 protection, resulted in fewer health complaints (Spearman cor. \(-0.246\)_p_ < 0.01 and \(-0.180\)_p_ < 0.01, respectively). As is depicted in Figure 8, the social distancing protocol, use of masks and sanitizers (personal or stations) and the installation of barriers between the occupants were three of the most commonly applied protocols in the offices.
