Assessment Of The Covid-19 Contagion Risk In University Classrooms With TRNSYS And TRNFLOW Simulations

The ongoing covid-19 pandemic has drawn the attention on the importance of providing adequate fresh air to the occupants of the built environment, in particular in educational buildings. Higher ventilation rates and personal protection devices like facial masks are among the strategies and procedures to reduce the infection risk, allowing the fruition of school spaces despite the epidemic progression. Nevertheless, the problem of airborne transmission has been usually dealt with considering each environment alone and assuming steady state conditions.

Cold comfort: thermal satisfaction in academia

This paper presents preliminary data on a series of building comfort experiments conducted in the field. We performed physical in-situ measurements and solicited responses from university students in six different classrooms at the University of Massachusetts-Amherst during three seasons (fall, winter and spring). Our questions focused on the students’ perception of comfort in varied environmental (temperature and humidity, and air speed) conditions. We collected records of the students’ academic performance in the classes, correlating their comfort perceptions to their test scores.
