The purpose of this study is to analysis the preference of the students on the outdoor spaces and the related facilities for creating the sustainable outdoor spaces in university campuses. The survey was conducted of students from three universities located in Jinju-si as the method of the study. Students preferred open spaces and green spaces the most, waterfront spaces the least as the outdoor space in university campus. Survey respondents preferred the spaces providing resting, amenity and communication as the general outdoor spaces. And they preferred the spaces providing functional and aesthetic satisfaction to the occupants as the sustainable outdoor spaces. Local community revitalization is the least responded among the reasons of preferring the outdoor spaces in campus. Students preferred bench, trash can and pergola as the facilities that needed at the outdoor spaces in campus. It seems students prefer the facilities to support their outdoor activities and rest-activities at the outdoor spaces. According to the overall result of the study, there are no significant differences between the preference for the general outdoor spaces and the preference for the sustainable outdoor spaces in campus. However, the study doesn’t clearly state the reason for the result from the preference survey stated above. This limit could be complemented in the later studies.

In this study, the heating performance evaluation for radiant heating method(Base) and convection-radiation combined system(Alt) was conducted. The convection-radiation combined method has a circulation structure in which the heat source returned after the supply hot water passes through the convection heat exchanger is introduced into the radiant heating structure and returned. The measurements were made by comparing standard radiant heating structures with the same size and comparing and analyzing the energy consumption according to the set temperature arrival time, floor temperature distribution and heat supply. The result of energy input was reduced 32%.
