Energy consumption all over the world is increasing rapidly and there is a pressing need to develop ways to conserve energy for future generations. Researchers are forced to look for renewable sources of energy and ways to use available sources of energy in a more efficient way.  Conventional refrigeration based vapor compression air conditioning systems consume a large portion of electrical energy produced mostly by fossil fuel. A novel dew point evaporative cooler (DPEC) can sensibly cool the incoming air close to its dew point temperature. In this paper feasibility of DPEC system is investigated for various Indian cities for office buildings during day time. Firstly the weather data of different cities of India is used to find the suitability of dew point technology for Indian buildings by estimating the cooling capacity of the cooling system for each city. Secondly energy saving potential of the dew point cooling system w. r. t. to the conventional compression based air conditioning system for different cities of India is estimated.
