Background:<\/strong> In the context of the fight against the COVID-19 pandemic, exhaustive ventilation strategies have been implemented in classrooms that have resulted mainly in the permanent opening of doors and windows.<\/p>\n

Objective:<\/strong> to analyse whether permanent and direct ventilation to exterior spaces compromises thermal comfort.<\/p>\n

The place:<\/strong> a classroom at the Barri Bes\u00f2s Institute in Barcelona during a workshop on the healthy and socially responsible use of mobile phones within the Impulsem Program of the Barcelona City Council.<\/p>\n

Starting situation:<\/strong><\/p>\n

a) Classroom with constant ventilation to exterior spaces (windows open) but keeping interior doors closed.<\/p>\n

b) Absence of air conditioning system.<\/p>\n

c) Number of students: 15-18.<\/p>\n

Methodology:<\/strong><\/p>\n

a) A sensor has been placed in a busy classroom to monitor the CO2<\/sub> concentration and the indoor temperature. CO2<\/sub> has been used as an indicator of the level of air renewal.*<\/p>\n

b) Values \u200b\u200bhave been taken on 3 different days: March 3, 19 and 24, 2021.<\/p>\n

c) When the CO2<\/sub> concentration approaches that which is considered indicative of not being in a safe environment to prevent the spread of COVID-19, the classroom renovation rate is increased by generating cross ventilation (opening the door interior) between the exterior and interior corridors of the building.<\/p>\n

* When we breathe we emit CO2, if we manage to maintain a low CO2 concentration, it means that the CO2 that we have emitted has been eliminated thanks to the renewal of air. Guide for classroom ventilation<\/em><\/a>, Institute for Environmental Diagnosis and Water Studies, IDAEA-CSIC-Mesura. November 2020. Based upon 5 Step Guide to Checking Ventilation Rates in Classrooms<\/a> <\/em>(Harvard).<\/p>\n

Results:<\/strong> the internal temperature of the classroom has always remained below 21\u00baC (winter), which is the temperature required by the applicable Spanish regulations (RITE-Regulation of Thermal Installations in Buildings) for winter. Therefore, it is considered that a comfort temperature has not been achieved.The students coped with the temperature by keeping warm clothes on inside the classroom.<\/p>\n
