This research was conducted to determine the indoor air flow throughout a multistory educational building. Due to increase in enrollments every year, classrooms are fully occupied which resulted in insufficient air flow in the classroom causing discomfort. This paper details numerous calculations to determine whether the multistory educational building's Heat Ventilation and Air Conditioning (HVAC) system was up to code by assessing the total amount of Cooling load and airflow, measured in Cubic Feet per Minute (CFM), within the building. The Cooling Load Temperature Difference (CLTD) method is a traditional method used while designing buildings HVAC system. Hence, the present study was conducted using the CLTD method to estimate the total cooling load and airflow in the building during summer season. The theoretical calculations were compared to measured values which showed difference in the airflow and cooling loads. The cooling load calculations measured in summer provided a dynamic approach to varying load and climate. The parameters assessed in the study include outside and room temperature, geographic position of building, occupancy, equipment, ventilation, etc. Fluctuations were noticed in the assessed parameters which affected the calculated CLTD load and CFM values in each room. The measured data was collected from the building's HVAC system to ensure the system was meeting the required demand of the load during the cooling season. The theoretical and measured data were compared for the summer season which shows that the Cooling loads and airflow within the building does not meets the building code standards for small classrooms.
