Thermal Performance and Energy Efficiency of Naturally Ventilated Classrooms: A Case Study on Some Urban School Buildings Located in Bangladesh

The paper mainly concentrates on the thermal performance of the naturally ventilated classrooms of the urban school buildings in Sylhet in Bangladesh. The focus lays on the significance of naturally ventilated classrooms in specific climatic zones the energy efficiency issues where some of those pictures based on the review of the prevailing ideas in the literature and case studies as well. The notion of the thermal impacts due to the natural ventilation is not merely a perceptual entity but also a physical reality. The aim behind the study is to determine the characteristic features of natural ventilation to visualize the theme of thermal environment inside of the classrooms and to understand the collective impacts from the present scenario of ventilation pattern. But, now, it has been identified that the concept of naturally ventilated buildings encompasses the energy efficiency, identity and amiability of the existent features. It comprises a significant physical comfort, healthy thermal environment and also minimizes the use of electricity and energy as well.
