The purpose of writing this proposal is to show how hot climate is a huge problem faced by students and teachers in schools and colleges. In addition to spending time at home, students spend a large part of the day at school or university, so having acceptable indoor air quality is very essential (Rossbach, 2013). According to Rossbach. (2013), “Classroom ventilation rates often do not meet building standards, although improving indoor air quality is considered important. Poor indoor air quality is believed to affect both the health and performance of children” (p.1). Although many students around the world struggle with heat and its negative consequences, a solution can be found by 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, expanding airflow in all California classrooms at state-mandated ventilation rates could have potentially critical impacts, analysts realized from the Lawrence Berkeley National Research Laboratory, the big financial state is expanding schools by $33 million due to a 3.4% reduction in school absences as schools are funded based on normal daily attendance (Adams, 2013). Furthermore, the conclusion of an in-depth study conducted by Jisung Park shows that hot weather has a negative effect on student learning and performance on tests and exams, in fact, if students took an exam on a 90 degree day the percentage of subsidence will be greater than 12% compared to a 72 degree day (Barnum, 2017). So, having an air conditioner in the classroom will reduce the percentage of absences along with failing grades. Adding conditioners to classes requires many methods and experiments to get a perfect result. According to Rossbach, a study called the FRESH study was conducted that relates to school environmental health related to forced ventilation in many randomly participating schools. In the performed experiment, there were two experimental groups and a control group, in which teachers were asked to ventilate classrooms by opening doors or windows, then a device with an external flow fan placed at the external on the wall, through which it was equipped with an air pump that heats or cools the external air before releasing it to the classroom. This experiment demonstrated that during the summer the air introduced into the classroom was cooler than the outside air while in the winter season the air inside the classroom was warmer than the outside air so that the temperature inside the classroom was suitable for all seasons (Rossbach, 2013 ). So much experimentation needs to be done for external and internal design and measurements. Installing air conditioners in classrooms is expensive and requires a huge budget, but the results after adding ACs are very expressive in many ways. As Barnum (2017) mentioned, “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 about a quarter of the city's classrooms, about 11,000 classrooms, don't have air conditioning,” New York City Councilman Brad Lander told WCBS radio in early spring. "And you know, on a cool day like today,.
