Many school buildings in the School District of Philadelphia (SDP) do not have air conditioning or proper cooling mechanisms, which disrupts learning and makes it uncomfortable and even dangerous for students and teachers to be indoors when it is hot out. This thesis investigates the relationship between the presence of air conditioners in Philadelphia public schools and the surrounding urban thermal environment to evaluate if these schools are well-equipped for rising temperatures. To do so, 30 schools with air conditioning and 30 schools without air conditioning in the SDP were randomly selected and mapped using Google Earth Engine. These school sites were then compared to map overlays of vegetation cover, land cover, land surface temperature, and urban heat risk. Schools without air conditioners were found to be located in areas with low vegetation cover, medium urban cover, and medium land surface temperatures. These ultimately contribute to a medium to high urban heat island effect, identifying these areas as vulnerable to urban heat risk. Additionally, when determining which schools to prioritize, school age, governance, and Community Eligibility Provision (CEP) rate were the best factors to consider. These findings provide evidence that several schools in Philadelphia are not prepared for hot temperatures and thus raise awareness regarding the current conditions of Philadelphia public schools. They also inform which schools in the SDP need to be prioritized for more resources and maintenance to increase resilience to global warming.
