Introduction: The presentation builds on previous papers about the right to choose between air conditioning-based ventilation and open-windows ventilation, above all to ensure that persons with high sensitivity to the factors causing sick building syndrome be given the possibility of avoiding them (an objective achieved by some firms through areas-partitioning). The SARS-CoV-2 pandemic has strongly highlighted the need for efficient air-recycling-free ventilation in indoor spaces, with experts emphasizing that opening windows is more effective for contagion prevention than the currently-ubiquitous disinfection. This work investigates selected features of the implementation of such recommendations. Material and Methods: The study utilised online interviews with teachers (mostly, secondary schools) and some persons working in other set-up types. The interviews focused on the practice of opening windows when working in-person. Information on feasibility and challenges, as well as suggested recommendations, were collected. Results and Conclusions: All the interviewed persons agree on the importance of opening windows, and practice it as much as possible under their work circumstances. They recommend the provision of extensive information at all levels, so that more students and co-workers can appreciate the practice. They hope that more attention is given to the indoor-air quality also after the end of the pandemic. Some discussions raised the point of the impact of poor indoor-air quality on the body’s resistance to pathogens causing respiratory diseases – an issue deserving thorough specific investigation by specialist.
The right to opt for natural ventilation (ventilation by opening windows) in the work place strongly reinforced by the realities of the SARS-CoV-2 pandemic
