  • Recently rapid urbanization facilitates development of high-rise building complex including apartment and office building in urban area. Many problems related with high -rise building are reported. Especially, unpleasant strong winds in pedestrian area are frequently encountered around the high-rise building. CFD simulation methods are used to analyze the wind environment of pedestrian level in high-rise building block. However, the results show differences between CFD and measurement. This difference is attributed to improper use of CFD. Conventional CFD simulation for wind environment around high-rise building does not describe the effect of trees, shrubs and plants near ground which affect the wind environment of pedestrian level. Canopy model can be used to reproduce the aerodynamic effects of trees, shrubs and plants near ground. In this paper, CFD simulation methods coupled with the tree canopy model to predict wind environment of pedestrian level in high-rise residential building block were suggested and the validity was analyzed by comparison between measurement and CFD results.

  • The objective of this study is to identify the research trend in the field of indoor environment in Korea. We collected 419 papers published in the Journal of the Korean Society for indoor environment between 2004 and 2018, and attempted to produce datasets using a topic modeling technique, Latent Dirichlet Allocation(LDA). The result of topic modeling showed that 8 topics ("VOCs investigation", "Subway environment", "Building thermal environment", "School health", "Building particulate matter", "Asbestos risk", "Radon risk", "Air cleaner and treatment") could be extracted using Gibbs sampling method. In terms of topic trends, investigation of volatile organic compounds, subway environment, school health, and building particulate matter showed a decreasing tendency, while the building thermal environment, asbestos risk, radon risk, air cleaners, and air treatment showed an increasing tendency. The results of this topic modeling could help us to understand current trends related indoor environment, and provide valuable information in developing future research and policy frameworks.

  • To promote environmentally responsible architectural practice, many nations have established their own green building rating system. Among other criteria, recently the indoor environmental quality section has been paid great attention due to Sick Building Syndrome, as this believed to caused by polluted indoor environment. In this context, indoor environmental quality is one of very important sections of each green building rating system and closely related to the very happiness of building users. The goal of this research is to compare and analyze the indoor environmental sections of three green building rating systems, GBCC, LEED v2.1, and BREEAM Office 2005, and find a direction for the improvement of GBCC. First, the three rating systems are analyzed in general to compare the importance of indoor environmental factors in each system. Second, the indoor environmental factors are reclassified within related sub-categories for the comparable analysis. Finally, based upon the comparable analysis, directions for the improvement of GBCC are as follows: 1. GBCC's h4r Environment Section needs to clarify its VOCs criteria based upon types of finish materials. 2. Sound Environment Section's noise control criteria needs to be revised based upon types of building usages and application method. 3. An indoor lighting related section needs to be included in GBCC, as even though light is the one of the most important factors in indoor environment, it has not been included in GBCC yet. 4. The sub-section of Confortable Indoor Environment Section related to the resting space and the universal accessibility are not in accord with the goal of green building rating system. These items need to be dealt within general building codes. 5. The rating evaluation structure and process need to be streamlined.

  • Eco-friendly architecture, generally speaking, is considered as the activity of planting more and designing ponds, therefore many clients and constructors prefer to avoid building so due to initial construction costs. This paper aims to examine the cognition of environmental equipment systems and the applicability of echo-friendly building constructions. We examined the designer's demands of building equipment systems and eco-friendly environment and tried to deduce desirable suggestions for the system. We should solve the fundamentals of economical problems in the construction of eco-friendly buildings and we better think that government should make it a policy to advertise it and to reform the taxation system regarding environment friendly buildings.

  • Since the Intelligent Building was first introduced in early 1980s, It has been studied and designed by related technical experts as it was called by the name of intelligent Building, High-tech Intelligence Building, High-capacity Building, Intellectual Building, etc. Despite the need for new concept as the relation between global environment and architecture has become an issue on a full scale since 1990s and with the development of high technology, former concept is maintained without modification or complement. Especially, attempt to combine industrial technology with architecture is essential to Intelligent Building, therefore frequent opportunity of self-innovation according to the development of technology is necessary. Due to the rarity of the high-technology and its high cost, it was adopted to large-scale construction, however, nowadays, almost all kinds of buildings are getting designed with intelligent-technology. Therefore we can expect that this trend will be accelerated by evolution of technology and will position as a major stream of future architecture along with environment-friendly architecture. Through this process, we should fully be aware of the importance of the several intelligent skin technology to protect global environment and to set future direction in architecture.
