These days are Low carbon green growth period. Green Korea, the environmental group have been announcing about University overconsumption energy and problems with the actual conditions. I think that the university is required reasonable management by using renewable energy that is sustainable as an alternative plan about those problems which pointed out from Green Korea. I'd introduce a case of the university facilities that are efficient and renewable energy practices.

Renewable energy is growing based on low-carbon green energy government policies. According to this policy, geothermal energy is highly efficient and environmental friendly energy which is being recently expanded. However, construction companies are generated disorderly but their ability has not been verified due to the poor geothermal facility which was reported in the media. In the this paper introduce on Busan region's largest geothermal facility, it was confirmed that thermal efficiency of the underground is close to heat exchanger performance. Therefore the study improving the efficiency of underground heat exchange found progressed. The results showed voids between borehole and ground heat exchanger should not be raised. And then geothermal facilities were installed very successfully through the principle grouting operation. As compared to the energy consumption on the basis of operating results energy usage was less than any other heat sources.

The floor heating system is a way using a radiant heat of hot water coils in floor of building and is a comfort system because of heating through a radiant heat of floor without a movement of air. In result, another countries such as China, Japan and Europe use this system and the needs for this system is increasing. The most important thing for floor heating system is to secure the optimal flow-rate, temperature and current for moving hot water in heating coils. In this study, we found out a cause and measure through a real case studies for a burst of heating pipe without an optimal current for moving hot water in heating system.
