In recent years there has been a lot of discussion with respect to the lifetime of buildings. To improve environment and extend the lifetime of buildings, It starts with designing. According to changes in environmental policy, the need for high efficiency in energy is increasing. Therefore, it is necessary to figure out the changing social needs, such as the change in the use of buildings and the contribution function. So, the demand for remodeling has been increasing.
In this paper, user’s tendency was observed and the optimal system was planed. it is intended to provide the remodeling technique through lowering energy consumption and improving the environment.
The study was conducted from January 1, 2007 to December 31, 2008.
The resulting values that are improvements and energy savings was investigated after the direct construction of the dormitory facilities of K University in Daejeon. The conclusions are as follows:
First, after the remodeling environment in university dormitory that is installation of external insulation and individual air conditioning, the reduction in energy cost was about 26,000,000 won.
Second, the thermal environment of each room was improved by application of the air conditioning system and the change of heating system to convection heating as warm air floor heating.
Third, through remodeling internal and external improvement in the dormitory, the cost of construction was saved 30~60%. So, this construction is more economical.
Fourth, the university renovation of aging facilities led to a significant reduction in demands made by the students, in turn, increasing the satisfactory rate.
The findings mentioned above provide the following implications.
In comparison to starting construction for new buildings, remodeling can accomplish the following: less construction time, cost reduction, and the creation of a pleasant environment.
Also, planning an optimal system leads to: energy saving, eco-friendly environment, convenience in maintenance and utilization of existing resources provides important implications such as economic benefits.
