| Abstract |
This study aims to provide architects with useful information by comparing with several alternatives, including double skin system etc., to save the energy as well as increase the quality of indoor environment without interfering with the expressed intention which an architect shows to the public by applying glass to the outer skin of building.
The research procedures were; 1) the previous studies were closely scrutinized, 2) selecting two glass-skin buildings in Seoul, the questionnaires to the occupants were conducted, 3) the measurements to indoor and outdoor temperatures including glass surface temperature, and intensity of illumination were proceded, 4) the results of the questionnaire and the measurements were carefully analyzed by Paired-Samples T-Test, ANOVA and Duncan-Test, and Chi-Squared Test using SPSS, Energy-Shading-Glare Simulations using VE(Virtual Environment; APACHE-SUNCAST-RADIANCE), 4) Several Alternatives were made to solve above problems and carefully analyzed by VE(Virtual Environment).
As a result of this study, 1) in the measurements of temperatures, the surface temperature of glass skin increase by 50℃ in small glass-skin buildings. Therefore it makes occupants feel serious discomfort by MRT and cause the increase of cooling load. 2) It is difficult to reduce the cooling load in small glass-skin buildings with considering indoor environment and energy problems rather than heating load. To solve that problem, double skin system is applied to design method with enough intermediate space and shading devices. |
