Project Details ? Assessment of Thermal Comfort Improvement using Calibrated Simulation Approach (A Hostel Building room at Hyderabad in composite climatic zone) DISSERTATION This was a Dissertation in curriculum of M.Tech. ‘Assessment of thermal comfort improvement using calibrated simulation approach in unconditioned buildings’ at Malaviya National Institute of Technology, Jaipur under guidance with Dr.-Ing Jyotirmay Mathur to evaluate thermal comfort improvement and energy saving in Gray (ordinary) roof and white roof; for the same the project is prepared at International Institute of Information Technology, Hyderabad under supervision by Dr. Vishal Garg at Centre for IT in Building Science. With application of cool roof coating, due to high reflectivity, a large part of the incident solar radiation on roof is not absorbed. Total seven RTD sensors are installed in IIIT hostel building top floor to measure the inside and outside temperature of both rooms roof and inside air temperature of rooms that are installed 3.5 feet below roof and a probe that collect ambient temperature is also installed in a shaded area on top floor. A Pyranometer is also fixed at top floor to catch solar radiation on thirty second average basis. After this all data’s are converted on an hourly basis to compare the actual temperatures and simulated temperatures of both rooms. Design builder and energy plus is used for modeling and simulation work respectively. The calibrated model is simulated with various measures like roof, wall, glass SHGC, glass U-value and combination of roof and glass SHGC with a final model which having all measures that cover maximum adaptive thermal comfort hours. All measures follow ECBC code values that improve the adaptive thermal comfort hours. The calibrated model is also simulated to three climate zone (Composite, Hot and Humid and cold climate) for India to evaluate the adoptions thermal comfort hours. SEMINAR The seminar which is a course work during M.Tech, I did choose “Adaptive Thermal Comfort (ATC)” which is having much importance in natural ventilated buildings along with conditioned buildings to set some adaptations so that energy can be conserved with little concern and learnt different models that have basic to thermal comfort start. The popular model that developed in 1970 by Prof. P.O. Fanger and some other models like Pierce Model and KSU Model. During this work I have also focused on various adoptions that can be used in natural ventilated Building to bring under comfort vote which also minimize the energy consumption in conditioned building. The adaptations depends on the climatic conditions for a case that is included in study showed 6.15% saving in energy with 1oC increase in conditioned space temperature with other factors like air velocity or some little variations in mechanical ventilation in case of natural ventilated buildings. In case of India petroleum conservation and research association (PCRA) showed a % saving in energy that is nearly 2% with change in set point to a 1oC. Workshop Attended 1.
