In order to achieve high efficiency of energy use and environment-friendly architectural design, various loads such as cooling, heating and hot water required by the building sector must be accurately predicted. Many studies used dynamic simulation tool to evaluate and analyze building energy performance. However, there are few studies on the comparative analysis of load results by each simulation and the evaluation of simulation characteristics and functions. In this study, the cooling, heating loads and energy demand of the buildings were evaluated using three dynamic simulations for the building with the same input conditions, and the characteristics of each simulation were compared and analyzed through the results. As a result of simulation comparative analysis, cooling, heating load and energy demand was lowest in square type and north-south direction conditions.

Construction project is necessary element for human life to upgrade the quality and convenience. However, due to its contradictory nature to the environment conservation, environmental pollution and damage, deterioration of natural scenery, noise/vibration, water quality pollution, etc. caused in the process of construction greatly affect the environment. The purpose of this study is to propose checklist for environment management can be used in construction phase. For this, we went ahead with the research by studying the existing research related to environment-friendly construction project management both at home and abroad, investigation and analysis of environment-related laws and ordinances, and drawing the checklists for natural environment and living environment at the construction phase. As a result, we were able to compile a checklist for nine items including geological features, animals and plants, use of soil, quality of air, water, and soil, construction wastes, noise, vibration, recreation, and sceneries. The checklist is structured in 4 grades and coded so as to allow it to be developed with the use of computer system in future. We hope that the checklist presented in this study will help lead the managers at the construction phase in construction development sustainable from the perspective of environmental conservation.

Purpose: As the energy consumed by buildings increases, there is a growing need for studies and technology development to address this issue. One of the solutions to excessive energy use by buildings is the light-shelf, which is a natural lighting system enabling efficient reduction in light energy, and research in this area has been intensive. However, most of the studies about the light-shelf are limited to the light environment, and thus the application of their findings to an actual environment in the form of a design may be problematic. Therefore, the purpose of the present study is to provide fundamental data for light-shelf design by carrying out a light-shelf performance evaluation on the basis of the light environment and the heating and cooling environment. Method: In the present study, a testbed was established to conduct a light-shelf performance evaluation by measuring the electric power consumption of lighting and heating and cooling devices depending on the existence of a light-shelf and its angle. Result: The findings of the present study are as follows: 1) With respect to the uniformity of the indoor light environment amenity, the optimum angle of a light-shelf was found to be $30^{\circ}$ for the summer solstice and the winter solstice. 2) With respect to the reduction of electric power consumption by indoor lighting devices, the optimum light-shelf angle at the summer solstice is $30^{\circ}$, at which time electric power consumption may be reduced by 10.2% in comparison with when no light-shelf is applied. However, at the winter solstice, a light-shelf may increase the energy consumption for lighting in comparison with when no light-shelf is applied, and this should be taken into account in the design of a light-shelf. 3) In terms of reducing the electric power consumption of heating and cooling devices, the optimum angle of a light-shelf was found to be $30^{\circ}$ for the summer solstice, while a light-shelf is inappropriate for the winter solstice since a light-shelf creates shade and thus increases the heating energy consumption. 4) To summarize the findings above, the optimum angle of a light-shelf is $30^{\circ}$ for the summer solstice, but the installation of a light-shelf may in some circumstances increase the energy consumed by lighting devices as well as by heating and cooling devices. Therefore, more studies and technology development may need to be performed to solve the problem of increased energy consumption at the winter solstice.

지구온난화 및 기후변화에 대한 전문 연구기관인 IPCC에 따르면 인간은 기후 시스템에 영향을 끼치고 있다. 이러한 기후 시스템의 변화는 기존 생육환경을 변화시켜 농업 분야의 식재료 공급에 문제를 야기할 수 있다. 이 문제를 해결하기 위해 수직형 팜은 안정적인 식재료의 공급을 위한 좋은 대안이 될 수 있다. 수직형 스마트 팜은 농작물의 생육환경 유지 및 관리에 깊은 관심을 쏟고 있음에도 불구하고 건축 공간에 온도, 습도, 조도, 산소, CO₂ 농도 등을 균일하게 구현하는 데에는 어려움이 있다. 공기의 균일성 확보를 위해 CFD 분석을 진행한 결과 주목할 만한 결과는 수직형 스마트 팜 내의 공기 균일성을 위해서는 적합한 CO₂ 농도를 장기간 지속적으로 분사하는 것이 유리하다는 것이다. 이 결과를 통해 수직형 스마트 팜에 최적화 된 생육환경 시스템을 효율적으로 계획할 수 있다. 본 연구를 기초로 수직형 스마트 팜의 최적화된 생육환경을 조성하여 효율적인 작물이 생산이 이루어진다면 농업 분야의 발전에 이바지 할 수 있을 것이다.

Focusing on the emergence of the basic course in American schools of architecture, in particular Gyorgy Kepes' courses at MIT, this paper studies the transformation of architectural pedagogy during the years after World War II. Kepes centered his architectural pedagogy on the picture plane, which was to function as the primary media for applying the principles of Gestalt psychology, that is the identification of the whole and its parts and the reciprocity between the internal human organism and the outside world. Kepes hence introduced a set of unconventional visual practices that were not readily assimilated to architectural conventions. Paralleling the establishment of the basic course, MIT also formulated a functionalist and spatial pedagogy with its two initial design studios, courses 4.721 and 4.722. These studios shared the notion that architectural design evolved from the inside toward the outside, an idea that took hold not just in the pragmatic environment of MIT's studios but also in conservative academic programs as well as in popular magazines, picture books, and exhibitions for the consumer public. The architectural surface became inseparable from the objects of art, furniture, and design, all of which were to be the generators of space. Hence, during the 1950s, the architectural surface provided a specific locus of intersection between the visual fundamentals of the basic course and the working principles of architectural design. Kepes, however, had by this time become disillusioned with architecture's potential as the medium of unity. Though he maintained the Gestalt logic of identity, he expanded it toward the goal of grander synthesis of society and consciousness freeing himself from the constraints of disciplinary instruction. In the case of Kepes, the mediating role of the picture plane was foregone in a regressive turn toward a primal, innocent, and direct experience.

This research paper explores selected behavioral outcomes of a multi-sensory environment. An experimental study was conducted at a specialized facility for the ageing in Sweden. The objective was to explore the effects of agitated behaviors of ageing residents with dementia and to identify any short-term effects. Appointed nursing staff was instructed to record physically and verbally agitated behaviors on three occasions; pre-session, mid-session, and post-session. Over seven months, nine participants received sixty-one sessions in the multi-sensory room. ANOVA and Post hoc multiple comparisons were performed to identify the differences in mean between each session. Generally irritated/frustrated behavior and eating/drinking non foods revealed statistically significant differences, while there were no significant results in verbally agitated behavior. One short-term effect was observed in one agitated category; a reduction of generally irritated/frustrated behavior. These results suggest that the multi-sensory environment can have positive effects on some manifestations of agitated behavior. This study proposes that a multi-sensory environment may be recommended as an alternative intervention for physically agitated behavior among this category of residents. However, more research is needed to understand the specific effects and the best use of the multi-sensory environment for this population.

Designing environments for the elderly includes studying changes in the elderly themselves, changes in their environment, and changes in the intercommunication between the elderly and their environment. The purpose of this study is to provide guidelines for a ubiquitous environment in which seniors can "age in place," using an environment-behavioral approach. 305 subjects aged 45 to 78 take part in the survey research. Temporal sequence (age groups) and behavior (daily activities) are considered as the significant variables to design digital services for the elderly in the perspective of an environment-behavioral approach. Several conclusions can be made. (1) The characteristics of subjects in the over-65 age group shows that they manage an independent lifestyle even if they realize some body functions deteriorate as they age. (2) Over-65 age group is more engaged in healthcare and pastime activities. The male subjects of it are most inactive. (3) The IDA (importance of daily activities) and FDA (frequency of daily activities) are classified by five to six factors in each group. The IDA and FDA of the group aged over 65 differ from other age groups. (4) Five affordance dimensions of digital services for the elderly are proposed: Healthcare, Domesticity, Mobility & Security, Network, and Recreation & Pastime. These affordance dimensions will help research groups or companies design ubiquitous environments to enhance the quality of life of seniors.

The thermal environment in a small city rapidly deteriorates due to the urbanization and overpopulation. It is important to understand and predict the thermal environment in a city area. The thermal environment is highly affected by the solar radiation and temperature distributions changing over time periodically. To predict the thermal environment precisely, the solar radiation calculation including radiation strength, incidence angle, and thermal radiation between building surface and ground should be considered. In this study, the computational domain includes various artificial structures such as building, ground, asphalt, brick and grass. To consider the solar radiation, the unsteady state numerical calculation is performed from sun rise to mid-day (2:00pm). The numerical methods consist of solar load and one dimensional heat conduction through the boundaries to reduce the computational load and improve the flexibility of the calculation.
