ENERGY-CONSERVATION IN HIGHRISE BUILDINGS - CHANGES IN AIR-CONDITIONING LOAD-INDUCED BY VERTICAL TEMPERATURE AND HUMIDITY PROFILE IN DELHI

Temperature and humidity profiles in the upper atmosphere are differen t from those observed by ground level meteorological stations and used to design HVAC systems for high-rise buildings. There exist correlati ons among solar energy, atmospheric turbidity and pollutants in urban areas, affecting the. temperature and humidity profiles with variation in height. In the present study, a theoretical model is developed con sidering these parameters, and the HVAC load is calculated. The result s are compared with the HVAC load calculated from data obtained from t he meteorological station, and the comparison showed that the results differ significantly (20%) for a hypothetical 200 m high office buildi ng.
