In building areas with high occupancy, such as classrooms, transmission routes of SARS-CoV-2 are increased when indoor air quality is deficient. Under this scenario, universities have adopted ventilation measures to mitigate contagious environments. However, the lack of adequate equipment or designs in old educational buildings is a barrier to reach minimum requirements. This study aims to quantify the indoor air quality and thermal comfort at universities and compare it to conditions in students’ households. In this regard, several classrooms in buildings of the Polytechnic University of Catalonia were monitored for temperature, CO2 concentration and relative humidity. The people who used these classrooms were surveyed about their comfort perceptions. A sample of students was also monitored at their homes where they reported to studying during the exam period. By means of point-in-time surveys, students reported their daily comfort, for comparison with the monitored data. The results show that the recommendations for CO2 concentration, temperature, and relative humidity are not always met in any of the study spaces. These factors are more critical at universities due to the high occupancy. In addition, the surveys highlighted the perception that the environment is better at home than at university.
The present work aims to describe and analyze the results of the interventions carried out in the Barcelona pilot site of the EmpowerMed project. The overall objective of EmpowerMed is to tackle energy poverty and to help improve the health of people in coastal areas of Mediterranean countries, with a particular focus on women. The main support approach implemented in Barcelona is Collective Advisory Assemblies (CAA), in the framework of Alliance against Energy Poverty. CAA is an innovative, collaborative empowering engagement tool that offers an alternative to the more traditional one-off individual household advice and support approaches. CAAs take place together with a monitoring campaign where: electricity consumption is analyzed to optimize the supply contracts, and indoor environmental comfort to provide recommendations for wellbeing improvement. Through the different approaches, a characterization of the people that have participated in the Barcelona pilot site was completed, from a socioeconomic, energy, thermal comfort and air quality perspective. Additionally, it was compared with a group of energy poverty non-affected households, which are involved in the monitoring campaign. Finally, the impact was quantified in terms of empowerment of energy poverty population and, potential economic savings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
