The purpose of writing this proposal is to show how hot weather is a very important problem facing students and teachers in schools and universities. In addition to spending time at home, students spend most of their day either at school or at university. It is therefore essential to have acceptable indoor air quality (Rossbach, 2013). According to Rossbach. (2013), “Classroom ventilation rates often do not meet building standards, even though it is considered important to improve indoor air quality. “Poor indoor air quality is thought to influence both the health and performance of children” (p.1). Although many students around the world struggle with heat and its harmful consequences, a solution can be found: installing air conditioners in classrooms. Say no to plagiarism.

According to Adams, a high percentage of absences are linked to illness in schools with poor ventilation. However, increasing airflow in all California classrooms up to state-mandated ventilation rates could have potentially critical impacts, Lawrence Berkeley analysts understood. National Research Laboratory, the major schools budget increases by $33 million due to the reduction in school absences by 3.4 percent, since schools are funded based on normal daily attendance (Adams, 2013). Additionally, the conclusion of an in-depth study by Jisung Park shows that hot weather has a negative effect on students' learning and performance in tests and exams. Indeed, if students took an exam on a 90 degree day, the failure rate would be higher than 12 percent, as opposed to a 72 degree day (Barnum, 2017). So, having an air conditioner in the classroom will reduce the percentage of absences as well as failing grades. Adding air conditioners to classrooms requires many methods and experiments to achieve a perfect result. According to Rossbach, a study was done called the FRESH study, which refers to the environmental health of schools related to forced ventilation in many randomly participating schools. In the experiment carried out, there were two experimental groups and one control group, in which teachers were asked to ventilate the classrooms by opening doors or windows, then a device was installed and with a flow fan exterior placed outside on the wall, by which it was equipped with an air pump which heats or cools the outside air before transmitting it to the classroom. This experiment showed that in summer, the air given in the classroom was cooler than the air outside, while in winter, the air inside the classroom was warmer than that outside , so that the temperature inside the classroom was suitable for all seasons (Rossbach, 2013). ). Many exterior and interior design and measurement experiments must be carried out. Installing air conditioners in classrooms is expensive and requires a huge budget, but the results after adding the air conditioners are very expressive in many ways. As Barnum (2017) noted, "New York City, where 1.1 million students attend the nation's largest public school system, announced in April that it would spend $29 million to air-condition every classroom by 2022. “More than one..
