Recently the architectural paradigm have been changing into eco-friendly architecture as an sustainable architecture. This social background encourages the development of various methods of building applicable for eco-friendly buildings in architectural design. Among them, passive architecture is an design approach for eco-friendly design that contrasts with technology-based methods through MEP for renewable energy. This study researches the Passive Architectural Design methodology with two points of view; Passive Architectural Design Techniques as a guideline, which defines the elements to consider for passive architecture, and the project of Sejong Municipal Public Library as a case, which is to analysis the architectural design process. The purpose of this study is to propose an eco-friendly public building based on the methodology which is suitable for passive architectural design. Finally, this study suggests that the eco-friendly public building design for passive architecture should consider from the early step of design process, such as concept and building form etc. What is important for the passive architecture is not how much building can produce the natural energy but how less building consumes it to maintain.

Increase in energy consumption in building is a big concern world over. In Nepal, energy crisis is a big issue but energy demand in buildings is barely even thought about. In the southern part of Nepal, where the weather is mostly hot during the year, cooling in buildings is very important. This is an initial study regarding building design strategies which focuses on cooling energy consumption in the building. It can be seen from the study that simple passive strategies can be applied in building design which can support in decreasing cooling load. Different passive cooling strategies like orientation, building size, thermal mass, window design and two direct cooling strategies have been investigated in this study. Direct cooling strategies like shading and natural cooling helps in passive cooling. Different desing strategies have different impact on the cooling energy requirement and the study shows that thermo physical property of building materials has the maximum effect on the energy consumption of the building. Each design strategy creates and average of 20% decrease in energy consumption, whereas the thermal conductivity can have as much as 10 times more effect on the energy consumption than other design strategies.

The purpose of this study is to analyze the planning characteristics of passive house by the building structural types in foreign cases. The interests and demands about passive house have been increased, and various building structural types and design methods have been attempted for passive house in Korea. But domestic research results and development experiences about passive house were lack. The results of this study are as follows; First, in terms of energy performance, insulation performance, airtightness, there are not significant differences at the 95% confidence level by the structural types of passive house. Second, in terms of the types of insulation materials, there are significant differences at the 95% confidence level by the structural types of passive house. Third, in principle there is no need of traditional heating facility in passive houses, but in practice traditional heating facilities are used additionally in about half of survey cases for the comfort of occupants.

This study analyzed the performance of passive solar system for office building. A unit model of the passive solar system was proposed in order to predict its performance under varying parameters and Seoul weather date. Steady state heat transfer equations were set up using a energy balanced equations and solved using a inverse matrix method. Numerical simulation program to analyze system was developed by using MATLAB. As the results, the passive solar system performance of office building was determined by the insolation and the outdoor air temperature. Also the passive solar system indicate 6.7~16.2% of annual average efficiency. In the comparison with other systems of the conventional wall, mass wall could reduce the heating loads of 7.1% and trombe wall could reduce heating loads of 11.5%. Through this study, performance of passive solar system for office building was verified by numerical method. Consequently, the passive solar system could operate an important role as the alternative for saving energy consumption of office building, and the additional studies should be made through the experimental method for the commercialization.

본 연구는 전과정 평가에 기초한 패시브 공동주택의 친환경성을 평가하는 것을 목적으로 한다. 이를 위해 LCA에 관한 이론적 고찰을 토대로 전과정 단계별 물량정보 및 에너지 사용량 데이터를 구축하였다. 또한, 국가 LCI DB에 기초한 원단위 데이터베이스를 활용하여 산성화, 부영양화, 지구온난화, 자원고갈, 오존층파괴, 광화학적산화물에 대한 환경영향을 평가 분석하였다. 그 결과 패시브 공동주택이 일반 공동주택보다 6대 환경영향에서 환경적으로 우수한 것으로 평가 되었으며 이는 에너지 소비량의 절감이 운영단계에서 6대 환경영향을 큰 폭으로 감소시켰기 때문인 것으로 분석되었다. 이로 인해 건설단계에서의 환경영향의 비중이 상대적으로 증가됨에 따라 기존 에너지 절감 중심의 친환경 기술의 적용과 함께 투입물량의 절감 및 환경영향이 적은 친환경 건축재료의 적용을 통해 전 생애 주기 관점에서 친환경 기술의 적용이 필요할 것으로 사료된다.

The world population is consuming more than 1/3 of the total energy for heating housings. Particularly in our country, 21% of the consumption energy is occupied by building section. Therefore, it is necessary to increase the energy efficiency in buildings, thus promoting a comfortable residential environment while minimizing energy consumption. Accordingly, this study presents considerations for implementing high-insulated and airtight passive houses. This study selected four houses with passive house design applied, performed building energy performance through PHPP2007, a German passive house design simulation program, and compared the building-specific heat loss and heat gain. As a result, the most vulnerable part to heat loss was turned out to be a window and the heat loss was caused by outer wall, roof, and ventilation. Accordingly, for the implementation of passive house, it is necessary to make a careful plan and airtight construction that are complementary to various parts through the energy performance analysis started from the design phase.

Remodeling for an aged building is emerging as a potential alternative towards the future of the building industry. It is a more effective method than the new construction in environmental friendly view. Most of remodeling were aimed at the improvement of the function of the deteriorated finishing materials. But, at the early stage of remodeling process, energy performance of a building can be improved by adopting passive design solutions such as daylighting and natural ventilation. The purpose of this study is to explain the passive design strategy in remodeling process and to suggest a application of LT method. LT method is an energy-design tool which responds to parameters available early in design development. It provides an output of annual primary energy for lighting, heating, cooling and ventilation in non-domestic buildings. LT method basically uses the concept of passive zone and non-passive zones and should be used to evaluate the energy performance of a number of options and to make comparisons. In this paper, the process of LT method is introduced and investigated an applicability in our office building.

In the past few years, the subject of passive heating has been the major area of our concern due to the specific climate conditions prevailing in our region. More recently, however, other important issues such as retrofitting, passive cooling, optimized integration of conservation and passive solar, and daylighting have emerged as the areas of frequent discussions. KIER, the sole R&D organization in solar energy technologies, has accomplished significant results in passive building designs and actual demonstrations of experimental passive buildings. As a result of such endeavor by KIER, the passive solar buildings have been very well received by the Korean public. The current number of passive solar buildings in Korea is well over 1,600 (as of Dec. 1986). In this paper, broad aspects of the present status of passive solar technology utilization in Korea are presented.

Recently, the response of a high-rise building to external dynamic force created by wind and earthquake has received much attention. This response is dependent on wind intensity, surrounding environment, building size, shape, mass, stiffness and amount of energy dissipation available in the system. The study has been done on these parameters. Attempts have been made to increase the damping in building system and thereby reduce structural response. These attempts have centered on adding an energy-dissipative system(passive tuned mass damper; passive TMD) to the building system and increasing the overall effective damping. In this paper the optimum condition of passive TMD will be derived with respect to random excitation and the properties of the optimum condition will have been studied.
