The development of new energy has attracted consideration attention due to the high oil price and environmental problems. In advanced country, they have tried to carry out a long range plan for energy. We need to develop new energy for Low Carbon Green Growth in Korea. The building is 30% among ratio of energy consumption in Korea. And in the past, heating energy was high ratio for energy using at home. But recently, the demand for cooling energy keeps growing due to rising average temperature on the earth and improvement of life quality. In this situation, the energy of lake water and ocean water has studied to utilize in advanced country because of low temperature at underwater. But the study for deep water is still a lot left to do. In this study, we analyzed district cooling system and the present condition. Analyzing the deep lake water cooling system in Toronto, we found an application of district cooling system using deep ocean water. Deep lake water uses heat source for district cooling and water source for city in Toronto. So reducing the initial cost, this city had economic effect. When DLWC was applied at existing building, the heat exchanger was installed instead of cooling tower and refrigerator. And the heat exchanger used to connect main pipe with cool water on city. System using deep ocean water can be applied as a similar way to supply cool water from lake to building.

Building components such as walls and windows causes the loss of many energy. The current of windows are using by the law standards that have been every reinforce the year from 2008. As the more reinforcement of legal standards, benefits of energy is possible to raising, But it is must to considered LCC and connectivity. In this study, the alteration for Law Standards is examininginfluence for initial cost. Accordingly, We are searches by using to windows products in domestic office building which choosing to window types in Law Standards, we are analyzed for initial cost of buildingout of the apartment.

The alternative energy has lately attracted consideration attention due to the high oil price and environment problems. Ocean water that is one of the natural energy sources should be getting popular continually to reduce the environment problems. Ocean water has the possibility that we can use various ways such as deep ocean water, OTEC, wave power. Deep ocean water is able to use direct cooling for heat exchange because its temperature is 3~4℃. In this study, we selected the model building for the economics of deep ocean water cooling system. The model building locates near East Sea and has deep ocean water intake system. If that building uses cooling system using deep ocean water, it could reduce the initial cost. And we compared a cooling system using deep ocean water with an existing system. The results of the study will show an economics and improvement of deep ocean water cooling system.
