Indoor Temperature and relative humidity of the Airborne Infection Isolate Room (AIIR) are important factors that directly influence the transmission of airborne pathogens such as COVID-19 MERS SARS and tuberculosis. Also it affects the thermal comfort and health of doctors and nurses. This research aimed to measure and assess Indoor Air Quality (temperature relative humidity and humidity ratio) of the AIIRs. Additionally the energy consumption of the AIIR was located in the Pediatric Ward (AIIR-1) Internal Medicine Ward (AIIR-2) and Surgical Ward (AIIR-3). The study found that the Indoor Air Quality (temperature relative humidity and humidity ratio) of the AIIR-1 were 26.50 °C 78.96 % RH 17.22 k/kg.da respectively. The AIIR-2 had the means of 26.83 °C 78.41% RH 17.46 k/kg.da respectively. Finally the AIIR-3 had the means of 24.10 °C 78.92 % RH 14.79 k/kg.da respectively. Compared with the ASHRAE standard the analysis results found that the value was higher than the acceptable standards of ASHRAE STD 170 and ISO7730 (21-24 °C, 40-60% RH 12 g/kg.da). Average Energy consumption of AIIR-1 AIIR-2 and AIIR-3 were 0.67 kWh/h 0.68 kWh/h and 3.45 kWh/h respectively. © 2021 IEEE.
