  • Establishing a success model of a specific information system is critical to understanding the mechanism of IS success, the various dimensions of IS performance, and the factors and their causal relations in IS success. As one of the key IT applications, the project management information system (PMIS), particularly the web-based PMIS (Web-PMIS), has played a significant role in construction management processes in Korea. However, there have been few research attempts made to construct a Web-PMIS success model. This study primarily aims to propose a Web-PMIS success model based on DeLone and McLean's IS success model, and to discuss whether or not the D&M IS success model can be applied to the construction Web-PMIS. A questionnaire was sent out to Web-PMIS users (construction managers and constructors), and 253 completed questionnaires were received. Through multi-regression analysis, it was confirmed that it is statistically acceptable to apply the D&M IS success model to the Web-PMIS. However, the explanatory power of the model is not sufficient, and some of the model factors are not statistically significant enough. Relying on the statistical analysis results, this study also discusses the development direction for the Web-PMIS success model.

  • The Ministry of Land, Infrastructure, and Transport has been promoting strengthening energy efficiency of old buildings through public green building remodeling projects since 2020. Green remodeling includes both essential and optional construction of passive and active elements. However, there is a lack of integrated designs of passive and active systems and no standards for prioritizing these systems according to the building's age. Therefore, this study examined six public libraries in central region 2 that were expected to be high energy consuming. Remodeling strategy priorities were selected based on potential energy reduction. The libraries were divided into three groups based on their year of construction, completed in the 1980s (Model 1), 1990s (Model 2), and 2000s (Model 3). ECO2-OD, based on ISO 13790 and DINV 18599, was used as the primary energy consumption analysis tool. Simulation results indicated Model 1 and Model 2 benefited most from higher insulation and replacement of mechanical equipment. Model 3 benefited most from upgrading to more energy efficient windows.
