DATABA CRATION AND ANALYI XAMPL OF RLATIONHIP BTN DLLING UNIT AND COOLING LOAD Basic study on thermal environment of condominium dwelling units, Part2 himon NIHI *1, hinya ATOH *2, hinichi HIRAO *3 and Atsushi TAAKI *4 *1 Research Assist., Dept. of Architecture, College of cience & Technology, Nihon Univ., M.ng. *2 Prof., Dept. of Architecture, College of cience & Technology, Nihon Univ., Dr.ng. *3 Technical Adviser, Mec co Life Co., Ltd. *4 Bau Physik Design Lab Co., Ltd., M.ng. IntroductionThe Japanese government has created a global warming countermeasure plan based on COP21 and are targeting an approximate reduction in CO2 emissions in the home department by FY 30 compared to the levels in 13. However, a dwelling unit design that improves the thermal environment and includes performance criteria has not yet been clarified. Based on the above, this study continues with the specimen and research method used in a previous report and focuses on thermal environment indicators. The following the design criteria related to insulation have been added: period cooling load (hereafter, cooling load),heat loss amount (hereafter, q) and solar heat gain amount in cooling period (hereafter, mc)and eaves depthopening height,a Building envelope element. A database has been created to evaluate both period heating and cooling loads. This study aims to illustrate successful management of a large quantity of data and show analysis examples of trends in dwelling unit design elements and the design criteria related to insulation. Method: The data sample used in this study is obtained from the Dwelling Units of the Condominiums selected for study in the previous report (1603 cases). Using this sample, the validity of the indicators was verified using a catter Diagram of the 2 variables: the elements of the Dwelling Unit Design and the design criteria related to insulation. Next, by elimination of the external conditions from the sample and using the catter Diagram subject to a Differential Analysis for each orientation, the trends of an optimum Thermal nvironment were verified for each element of the Dwelling Unit Design. Results: First, Cooling Load and the design criteria related to insulation were compared for each element of the Dwelling Unit Design using a catter Diagram. Consequently, the effectiveness of the indicators used for the Thermal nvironment could be confirmed for each element. However, it was revealed that to perform a factor analysis, including the external conditions is necessary. Then, the external conditions were eliminated from the sample and a correlation of each element with the Dwelling Unit Design was established. Accordingly, under certain conditions, a correlation was observed between the elements of the Dwelling Unit Design and the design criteria related to insulation so that the trends for Dwelling Unit Design elements that could improve the indicator results for the Thermal nvironment could be determined. Conclusions: e clarified the indicator validity in each thermal environment using building envelope elements. Next, we excluded external conditions and showed examples of analysis using building envelope elements to clarify the possibility of reducing the cooling load through a dwelling unit design. In the future we intend to identify the elements with largest impact by means of a factor analysis. (17 年 8 月 日原稿受理,18 年 1 月 23 日採用決定 ) 831
