  • There are a number of policies that have been established to reduce greenhouse gases emissions and reduce energy consumption. These polices, however, only reflect the building energy consumption saving rate without considering building energy consumption characteristic. If building that already use less energy apply the same saving rate to reduce energy consumption, it is less effective. Therefore, this study classified building energy consumption characteristics and investigated approaches to adopt individual reduction rates according to energy consumption. Analysis results showed that there are differences in energy consumption depending on building use, and therefore, we classified buildings by use. We also proposed a formula to set a reduction goal for rate of energy consumption according to energy consumption. We verified our approach in a top-end neighborhood facility in Seoul. The energy consumption savings goal of this study can be applied individually, but determining whether a building can reduce energy consumption towards a saving goal requires a closer look at each building.

  • As there are a lot of differences in the public building construction cost depending on the construction scale of actual construction cost system, a lot of problems occur in the estimation of the cost. So, the development of a predictive model depending on the construction scale shall be used in a way that it is applied to the case selectively and differently. This study drew a cost estimating model through a regression analysis. For this, 42 construction sites which were ordered during 2011 to 2012 by Public Procurement Service data were selected as a historical data. Based on the application of the model to new construction and the verification of its effect, the reasonable model for estimating the construction cost has been suggested.

  • As abnormal climate phenomena frequently happen due to the after-effect of the global warming, all nations suggest climate change response policies in many different fields to prevent global warming by reducing greenhouse gas. Especially, these days, the realization that the greenhouse gas from city buildings should be decreased is growing, and it is because that buildings are accounted for a quarter of national greenhouse gas emission and it is more than half the percentage of emissions within the city. Accordingly, Korean government sees the need to take an initiating role to fulfill low-carbon green policies and promotion strategies in the public sector, and wants to facilitate greenhouse gas reduction in the private sector as well. In this background, this study tries to examine the low-carbon planning element in public buildings and figure out the amount of carbon reduction and economic analysis centering Cheongju city as case study. Lastly, we propose some suggestion for low-carbon and greening of public buildings.

  • This study investigates the effectiveness of Jeju's public Wi-Fi policy for which the key factors of public Wi-Fi use and location characteristics are analyzed. Spatial regression analysis was conducted within a 100 m radius of public Wi-Fi access points. In the analysis, the dependent variable was public Wi-Fi usage time while independent variables included demographic factors, location factors, and other factors. The findings reveal that demographic factors such as the number of residents, the number of workers, and the number of visitors had a close correlation with the use of public Wi-Fi. In addition, the number of bus stops and land prices of each parcel, land use mix, and AP installation period had a positive correlation with the use of public Wi-Fi. On the contrary, the number of buildings by use, the total floor area of buildings, and the number of tourist attractions had negative correlations with public Wi-Fi usage time. These findings provide policy implications that more active publicity on Jeju's public Wi-Fi is needed and the convenience for access needs to be improved.

  • This paper is concerned with the domestic and foreign PV integrated projects in view of structural design. These projects are classified with public and display 6 facilities. The evaluated items are natural integration with building, engineering details and innovative new design. 6 domestic public and display facilities are frequently using isolated supporting system at roof, but show weakness in design integration. But the cases, using the PV panel in the stage of design some display facilities, are increasing. In the other hand, foreign public and display facilities are using the modul connection majorly and the structural and design integration are obtained.

  • Han-ok has been forgotten by rapid industrialization, however, recent interest in Korean traditional culture and eco friendly architecture are increasing. Government is also processing various policies and research in Han-ok for historical reasons. Still Han-ok is considered as temporary discover stage not daily space. Moreover, previous weakness of Han-ok made it difficult to supply. There is a need to build new Han-ok style public buildings different from traditional or new Han-ok for revitalization of Han-ok. Moreover, development of new Han-ok style public buildings model are needed for the public which include updated concept and function. From public buildings model development and supply people can visit and explore Han-ok. Therefore Han-ok tradition can be modernized. In addition to this Korean traditional culture and mode of living can be developed and conserved. This research focuses on public buildings of Han-ok supplication and aims design elements and regional trend.

  • The purpose of this research is to develop a conceptual model that establishes a new approach for functional area cost estimating in the schematic design phase. A cost estimating model should consider not only the estimate accuracy, but also the flexibility to the design alternatives and user-oriented serviceability. Therefore, this research uses the method that classifies various facilities of a building according to its functions by analyzing historical data. After setting the functional area as cost parameter, a formula which can estimate functional area cost is derived from statistical analysis. Finally, to validate the proposed conceptual model, it is applied to historical data of a military barrack project. It enables customized space planning reflecting client's needs and compares the cost of various design alternatives as well as improves estimate accuracy.

  • In this study, an algorithm was developed to validate the seismic acceleration measurement data of the seismic acceleration measurement system using measurement data from public buildings currently in operation. Through the results of the study, an algorithm was developed to detect errors and abnormalities in the measurement data itself and the process of generating real-time data (MMA/sec) and event measurement data (MiniSEED), which are the main data generated by the system, and the basic data for determining the direction of inspection through measurement data analysis. It is expected that this will be used as a guideline to determine whether or not the seismic acceleration measurement system, which was managed as receiving/not receiving, is inspected and abnormal types of conditions.
