Modern world emerging with lot of amenities to get comfort but in adverse the world is warming and other problems related to air quality, diseases are occurring. The resources are limited and population is increasing, demand is increasing and all people have a role how to utilize the resources in proper manner with researchers, engineers, medical practitioners and all. Unites nation ( U.N) is holding seminar to utilize resources in proper way and try to introduce nvironment friendly refrigerant related to global warming and Ozone depletion and encourage in designing considering alternative energy sources like solar, wind, biomass, fossil, tidal , nuclear etc to keep the environment green.In this paper A LEED platinum project (An office building) which was completed in 2009 in Madras, India, the brief description will be presented. The credit is scored according to USGBC ( United states global building council) related to energy saving which considers solar energy / wind energy for electricity eneration related to operation of pump , lighting , design in consideration with day lighting, air conditioning with solar absorption system by utilizing hot water as source of heat with the help of solar collector.A comparison will be made between standard air conditioning system considering Vapor compression cycle with absorption system considering solar heat and also the cost implication and its pay-back period. The equipment cost is decreasing as technology is improving and payback period is becoming lesser and people are becoming conscious to build up green environment.

Solar collector, water as refrigerant, USGBC platinum rated,
