Centre for Advanced Research in Building Science and Energy (CARBSE) at CEPT University has developed a ‘Multi-city Comfort and Weather Analysis’ tool. This is an online tool, to be accessed freely over the internet. The tool has been designed to help the user generate thermal comfort and outdoor weather analysis and compare results for two Indian cities simultaneously. The tool efficiently produces the following information:
Comfort charts showing the temperature of the city for the whole year on the ASHRAE 55 thermal comfort bands.
ASHRAE 55 comfort zone distribution on 24 x 7 basis for a year and also daytime basis for the city selected by the user. The user can hence determine the number of operating hours that belong to comfort zone for a particular month.
This tool also develops the weather chart which shows the temperature distribution on 24 x 7 basis and also daytime basis for the city selected by the user. The humidity distribution in for 24 x 7 spaces and daytime spaces for the user selected city will also be shown.
This tool is supported by Ministry of New and Renewable Energy, Govt. of India and Shakti Sustainable Energy Foundation, India.

Expertise Required: 

Basic knowledge regarding thermal comfort and weather conditions

Audience: 

Architects, MEP Engineers, Energy Analysts, Students

Input: 

Basic information such as geographical location, type of thermal comfort or weather analysis required

Output: 

Comfort and weather charts mentioned below for the specific geographic location along with a comparison of data of two cities can be viewed on the screen:
• Adaptive Comfort Zones (ASHRAE 55) for naturally ventilated spaces
• Weather data analysis showing annual temperature and relative humidity distribution and estimated operation modes (e.g. heating, natural ventilation, cooling, etc.) for 24 hour and daytime operating space
s

Strengths: 

Calculator provides quick comparison of information regarding adaptive comfort zone and operation modes of the building based on weather data, which is extremely helpful in initial building design and analysis.
