  • Buildings, energy and the environment are key issues that the building professions and energy policy makers have to address, especially in the context of sustainable development. With more tall buildings constructed in China, the impact on energy consumption and carbon emission would be great from buildings (2% increase of carbon dioxide annually between 1971 and 2004). The imperative was to investigate the building energy performance of high-rise in different climate zones and identify the key design parameters that impose significantly influence on energy performance in sustainable building design. Design implications on glazing performance, sizing of the ventilation fans, renewable energy application on high-rise building design are addressed. Combination of effective sustainable building design strategies (e.g., building envelope improvement, daylight harvesting, advanced lighting design, displacement ventilation, chilled ceiling etc.) could contribute more than 25% of the total building energy consumption compared to the international building energy code.

  • 도시는 어제와 오늘 또 내일이 공존하는 삶의 공간이다. 때문에 도시에는 고궁이나 옛 건축물이 있고, 화려하고 심플한 현대건축물도 있으며 미래지향적인 작품들도 잇다. 이렇게 많은 요소와 함께 시간에 흐름을 한 공간에서 느낄 수 있는 곳이 바로 도시라고 할 수 있다. 그 동안 우리는 국가와 국가 간의 경쟁 속에서 살아왔다. 그러나 요즈음은 도시와 도시의 경쟁체계로 바뀌어 가고 있다. 즉, 한국에 경쟁상대는 대만이라든가 프랑스, 독일이라고 했다면 오늘날에는 서울과 동경이 경쟁 혹은 부산과 파리의 경쟁 등 좀 더 세부화 되어 가고 있는 것이다. 강력한 설정을 가지고 경쟁력을 높이고 있으며 부산, 광주, 인천, 대구 등 모든 도시가 각각에 특성을 강조하고 있다. 이런 도시계획에 있어서 경쟁력의 중심에 도시야간경관과 조명에 대한 중요성이 새롭게 인식되어가고 있다. 이제 도시는 주간 시간대와 함께 야간 시간대에 중요성을 강조하고 있으며 도시에 생명력은 조명에 역할이 상당부분 차지하게 된 것같다. 이런 시점에서 그러면 도시의 경관 또는 조명연출계획은 어떻게 구성, 혹은 구상되어야 하는지 알아보고 검토하는 것이 경쟁력 있는 도시를 만드는데 큰 도움이 되지 않을까 생각된다.

  • Empirical applications to explain criminogenic events are abundant. While much of the research in criminal studies concentrates on understanding the motivations of offenders and preventing victimization from a micro perspective, there have been recent theoretical advancements that give priority to the role of spatial factors in directly impacting crime rates. The primary purpose of this study is to investigate the empirical inference between violent crime incidence and spatial characteristics of local areas focusing particularly on spatial accessibility conditions in the areas. Applying discrete spatial econometrics models, this study reveals a significant relationship between spatial accessibility and the formation of violent crime hot spots in South Korea. Along with other variables, it is revealed that road accessibility has a clear association with violent crime hot spots. Based on the findings, this study suggests some policy implications such as effective surveillance systems, land use restrictions, and advanced street lighting.

  • Recently, there has been active research on smart street lamps that can collect real-time traffic data and provide traffic information by attaching images and radars to road lighting facilities. Smart street light technology can detect, identify, and provide dense information compared to existing technologies. In order to effectively utilize the smart streetlight as a high-resolution information delivery medium, a branch-type operation strategy that is different from the existing centralized operation strategy is required. This study presents dynamic information delivery strategies, release strategies, and their criteria for various purposes in a spatial range, separated by the context before and after the occurrence of smart street lights-based accidents. Through this, it is expected that smart road lighting facilities can be used more effectively.

  • In this study, annual site and primary energy use intensities (EUIs) and $CO_2$ emission intensities (CEIs) per area by end use were estimated based on the measurement data from June 2016 to May 2017 of 19 sample office buildings in Seoul. In addition, the estimated site EUIs by end use were compared to the U.S. Commercial Buildings Energy Consumption Survey (CBECS) 2012 data. Average site EUIs by end use were found to be in the order of electric appliance (typical floors) > heating > cooling > lighting > air movement > domestic hot water > vertical transportation > city water supply. In the case of primary EUIs and CEIs by end use, electric appliance was found to be the largest. As results of comparison with the CBECS 2012 data, it was found that the site EUIs were similar for heating, cooling, domestic hot water, and electric appliance, etc., but slightly different for lighting and air movement. The number of sample office buildings will continue to increase until 2020 (total number of samples 85) and intensities data by end use will be continuously updated through continuous collection of measurement data.

  • Purpose: This study was aimed at providing the basic checklist as a means to assess the crime risk in physical environment of the pedestrian passage at residential area. Method: For this purpose, the preliminary checklists were selected according to the review of the precedent studies of checklists in exterior pedestrian passage. The usefulness and the importance of the preliminary checklists were analyzed through the seven expert group meetings, the 87 questionnaires survey of the crime experts & the architectural/urban experts, preliminary assessment and field survey. Results: The assessment categories of checklists were sorted into six types, i.e. spatial structure & function, lighting, landscaping, security facilities, other facilities and cleaning & maintenance. The 49 checklists were proposed according to the assessment categories. The final checklists were divided key checklists and general checklists based on the results of experts' weighting of each list item. There were significant differences between crime experts' weighting and architectural/urban experts' weighting in several checklists, i.e. dividing between pavements and streets, the brightness of light, white light.

  • Traffic signal is one of the major factors that affect the amount of vehicle emissions on urban highway. The amount of vehicle emissions in urban area is highly affected by the vehicle's cruising speeds heavily influenced by the traffic signal lighting conditions. It was attempted in this study to trace the changing patterns of the vehicle emissions by collecting the emission data from a set of simulation studies and by categorizing vehicle cruising conditions into four different groups: idling, acceleration, deceleration, and running at a constant speed. Authors propose a simple emission model prepared based on Kinematic theory. The validation test results showed that the amount of the emission estimated by the proposed model was relatively satisfactory compared to the one of the existing model employing the average speed data only as the determinant.

  • Recently, park usage for environmental education has gained popularity in Seoul. Therefore this study was performed by analyzing the status and problems of nature classrooms in neighborhood parks and citizen's parks that are located in residential areas in Seoul, and then by suggesting improved methods and user programs. The results of this study are summarized as follows. 1) 18 out of 281 neighborhood parks and citizen's parks have nature classrooms in Seoul. Facilities of nature classroom are comprised of direction signs, plant name card, pond, pavilion, pergola, bench, green house, waste baskets, lighting, drinking fountain and others. However, they have many problems in terms of quality. Nature classrooms were classified into three types according to their location in each park. Among the three types, the most popular type was the one that is a part of a park A Total of 479 species of plant (155 species in tree, 324 species in herb) were planted in nature classrooms. There are many kinds of environmental education user programs, but these are not connected with the nature classrooms. Most nature education programs in nature classrooms were self-guided. 2) The Problems that appeared were the featureless place composition, a lack of programs related to nature classrooms, access restriction to certain natured areas, and so on. 3) Finally, this study suggests some solutions to the problems of nature classrooms in urban parks. The solutions include full access to the parks, the creation of diverse theme, and setting up interesting panel and leaflets in order to encourage more active self-guided education.
