Supported by Ministry of New and Renewable Energy Govt. of India and Shakti Sustainable Energy Foundation, New Delhi, Centre for Advanced Research in Building Science and Energy (CARBSE) at CEPT University has developed some online tools to generate thermal comfort and outdoor weather analysis for Indian cities. ‘Comfort and Weather Analysis Tool’ analyses single city while ‘Multi-city Comfort and Weather Comparison Tool’ allows comparison various parameters of two cities simultaneously. The tools use weather data files for selected cities and generates comfort charts showing the temperature of the city for the whole year on the ASHRAE 55 thermal comfort bands. The user can determine the percentage of operating hours that would fall within the comfort zone for a particular month for a 24 hours as well as daytime operational building. This tool also provides the weather chart showing temperature and humidity distribution on 24 hour and daytime basis for the selected city. The tool also provides estimated percentage of operating modes for building such as heating, natural ventilation, cooling and dehumidification on annual and monthly basis. The tool is extremely useful in pre-design stages of buildings.
