Variations in classroom ventilation during the COVID-19 pandemic: Insights from monitoring 36 naturally ventilated classrooms in the UK during 2021. [PDF]

J Build Eng, 2023
Seasonal changes in the measured CO 2  levels at four schools are herein presented through a set of indoor air quality metrics that were gathered during the height of the COVID-19 pandemic in the UK. Data from non-intrusive environmental monitoring units were remotely collected throughout 2021 from 36 naturally ventilated classrooms at two primary ...

Natural Ventilation Characterization in a Classroom under Different Scenarios [PDF]

International Journal of Environmental Research and Public Health, 2021
The COVID-19 pandemic has pointed to the need to increase our knowledge in fields related to human breathing. In the present study, temperature, relative humidity, carbon dioxide (CO2) concentration, and median particle size diameter measurements were taken into account.

NATURALLY VENTILATED CLASSROOMS: CO2 AND COVID PROTECTION

DYNA ENERGIA Y SOSTENIBILIDAD, 2022
ABSTRACT: Natural ventilation has become one of the most effective and sustainable strategies to address COVID-19 in confined spaces. Air intake through windows and other openings improves the Indoor Air Quality (IAQ) of a classroom, decreases the likelihood of respiratory disease transmission with an adequate social distance of about 1.5 m and is ...

Experimental study on indoor environment quality in a naturally ventilated classroom of a university using natural ventilation and ventilation fan [PDF]

E3S Web of Conferences, 2020
Strengthening indoor ventilation is an important measure to improve air quality. In transitional season between spring and summer, a university classroom in Jinan city was selected as the research object. Mechanical air supply is adopted to solve the problem of insufficient fresh air or excessive carbon dioxide concentration in the classroom.

The CO2 assessment in a school classroom for an optimal natural ventilation strategy = The CO2 assessment in a school classroom for an optimal natural ventilation strategy

Building & Management, 2021
AbstractThe global pandemic due to the COVID-19 disease has led to the study of school classrooms as possible vectors of contagion. The CO2 has been established with an easily captured indicator to determine the adequate ventilation of these spaces. However, continuous ventilation can cause a lack of comfort in students and therefore be detrimental to ...

CFD simulations of thermal comfort in naturally ventilated primary school classrooms [PDF]

Thermal Science, 2016
The purpose of Thermal Comfort is to specify the combinations of indoor space environment and personal factors that will produce thermal environment conditions acceptable to 80% or more of the occupants within a space. Naturally ventilated indoors has a very complex air movement, which depends on numerous variables such as: outdoor ...

VARIATION OF NATURAL VENTILATION WITH FLOOR LEVEL AND ORIENTATION OF CLASSROOMS

International Journal of Education, Psychology and Counseling, 2022
In recent times, the multi-story school building has emerged as a new trend in Nigeria due to land cost in the urban area and population increase due to urban migration resulting from insecurity in rural areas. Among other factors, the floor level and space orientation are believed to affect its natural ventilation.

Indoor Air Quality in U.K. School Classrooms Ventilated by Natural Ventilation Windcatchers [PDF]

International Journal of Ventilation, 2012
AbstractThe provision of good IAQ in schools is important both for the health of students and in maximising educational achievement. It is, however, common for school classrooms to be significantly under-ventilated and this can lead to high levels of CO2 and other pollutants. Natural ventilation offers the potential to improve IAQ within schools whilst,
