Thermal comfort assessment for naturally ventilated classrooms during summer in composite climate of Jaipur
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 12
Abstract
Background: Considering the importance of comfort requirements in classrooms and the fast growing number of institutes for higher education in India, classroom thermal comfort needs serious attention. Methodology: Thirty classrooms in three university buildings with a total of 900 students participated in field study: 729 males, 171females. The transverse type surveying was used. Thermal environment variables were recorded according to Class-II protocol of ASHRAE 55. We statistically analyzed occupant’s thermal sensations, preferences and acceptability for prevailing indoor conditions. Objective: Assessing occupants’ thermal comfort conditions in classrooms under naturally ventilation mode during peak summer season in composite climate of India. Results: About 80 % subject’s responses were found in comfort band (±1 sensations) during field study in naturally ventilated classrooms. The mean comfort temperature, as predicted by Griffith method was 29.8 ˚C. Conclusion: The results show that the subjects in naturally ventilated classrooms are comfortable at temperatures different from those suggested by the current Indian and international codes/standards.
