This study aims to investigate the eco-friendly planning methods for a sustainable apartment houses in the Metropolitan area of Seoul. Eco-friendly plans that considers the environmental issues were attempted from the beginning of 2000s, and since then, many apartment houses in Korea were built using this concept. They were, however, generally focusing on the physical and spatial aspects of the site plan. After the Seoul C40 weather summit conference in 2009, the low carbon green housing standard has been emphasized and thus the chemical concept was added to the existing physical planning methods. Under such a background, this study intends to investigate the eco-friendly plans for the apartment houses in the 2000s. This includes an ecological network plan, an ecological base plan, a building greening plan, a water treatment plan, and an energy saving plan. Based on the analysis and synthesis of these planning methods in the early 21st century, it would be possible to set up a proper future plan to enhance the sustainable built environment in the housing industry in the coming years.

Caltech's Linde-Robinson Laboratory was originally built in 1932 featuring a Spanish mission-style design, whose function was to facilitate a solar observatory with a coelostat solar telescope dome and a solar shaft extending from the roof to more than 36.58m below the ground. The building has now been transformed into a cutting-edge center for research and instruction in global environmental science that retains its original character while setting new standards in energy efficiency and green design. It is the first LEED Platinum lab in the USA for renovation of a historical research building, consuming only one-sixth of the energy that the lab's comparable laboratories do. This work introduces various energy and environmental strategies hired for its sustainable rehabilitation and, especially, examines the functional validity of solar telescope daylighting by a coelostat. Observations were made on the llumination of underground floors, where illuminances of 40~50 lx were measured.

The building construction sector has been blamed as the main culprit of environmental contamination worldwide. So, there shall be some constructive alternatives in architectural engineering. As one of the alternatives, the LEED ("Leadership in Energy and Environmental Design") has been introduced since 1990s and has been well recognized in saving the resources and energy. "LEED" has also been introduced in Korea since 2002 but it has not put priority on the eco-friendliness of indoor space. In this study, the international and domestic green systems were analyzed and compared in order to restructure the checklist for indoor space. Using the restructured checklists, the questionnaire were sent to 180 people using 6 office buildings which passed the domestic "LEED" certification. LEED certification system put priority on the air quality and heating/cooling environment in its evaluation section and items. However, according to the results of the study, it was found that the people using the buildings were not satisfied enough with the air environment of buildings along with their other indoor environment items. This shows that even though the office buildings are designed according to the requirements of LEED, the buildings do not meet the occupier's needs. In addition, it showed that the evaluation items should be improved so that they are useful to enhance the satisfaction of the occupiers' needs. The paper could be useful in establishing standard for eco friendliness of indoor space of office buildings which pass the LEED certification as the basic data for increasing energy efficiency and working efficiency of occupiers of the buildings.

The Leadership in Energy and Environmental Design (LEED) Green Building Rating System provides third-party verification for environmentally sustainable construction. But while LEED-certified buildings provide healthier work and living environments, Previous studies have shown that LEED certification does not provide any direct economic incentives to owners and developers. To address this issue, this study aims to investigate the economic benefits of LEED criteria. The objective of this study is to examine whether or not there is a significant correlation between median household income and the number of bus stops and light rail stations for a given parcel that meet LEED sustainable site criteria for public transportation access. The findings showed that the number of bus stops had a positive correlation with median household income, which means that more bus stops a given parcel had that met LEED criteria, the greater the median household income of a block group where the given parcel was located would be, though this positive correlation was very weak.

The aim of this study is to evaluate the performance of the GHP system with 150 energy piles for a commercial building. In order to demonstrate the feasibility of a sustainable performance of the system, simulations were conducted over 1-year and 20-year periods, respectively. The 1-year simulation results showed that the maximum and minimum temperatures of brine returning from the energy piles were $23.80^{\circ}C$ and $7.90^{\circ}C$, which were in a range of design target temperatures. In addition, after 20 years' operation, these returning temperatures decreased slowly to $23.05^{\circ}C$ and $6.98^{\circ}C$, and finally reached to stable state. The results also showed that the energy piles injected heat of 65.6 MWh to the ground and extracted heat of 96.0 MWh from the ground, respectively. Also, it is expected this GHP system with energy piles can operate with average SPF of more than 4.15 for long term.

The objective of this study is to analyze the major factors of indoor environment that affect the satisfaction of the occupancy in multi-family residential buildings. The results of this study can contribute to improving the comfort of the residents effectively as they are applied preferentially at the design and construction stages. The indoor environment factors investigated for the analysis included thermal, light, air and the acoustic environment. The individual factors were derived from the 'indoor environment' assessment indices of the green building certificate systems of various countries. Based on these, a questionnaire was prepared to conduct the Post Occupancy Evaluation. The survey results were statistically analyzed.

Indoor Air Quality is crucial in hospital projects to ensure the health and safety of patients, staff, and visitors. The research methodology comprises an comprehensive literature review, then a comprehensive questionnaire survey conducted among stakeholders involved in Vietnamese hospital projects. 15 variables were identified and categorized into four distinct groups, elucidating their influence on the adoption of advanced IAQ-enhancing technology. This study uses factor analysis, a mean score method and hypothesis test to analyze the factor result from the survey. two-step process, including an in-depth literature review and questionaire survey. The study's findings culminated in the ranking, examination, and categorization of these 15 variables, which were clustered into four essential categories: economic factors, design elements, governance strategies, and technical requirements. Additionally, the research explored viable solutions to improve indoor air quality in Vietnam's unique environmental context, examining the factors that impact the selection of such solutions. The study's outcomes yield practical recommendations for architects, engineers, and hospital administrators in enhancing IAQ within healthcare facilities. Furthermore, it presents a framework attuned to local environmental factors and building materials, contributing significantly to the existing body of knowledge on IAQ within hospital projects, particularly in the Vietnamese context.

본 연구는 현재 시행 중인 "녹색건축물 조성지원법"의 녹색건축 인증제도의 평가 기준에 대한 분석을 하였다. 아울러 2012년 11월부터 2015년 11월까지 3년간 녹색건축통합운영시스템(G-SEED)에서 인증 받은 총 78개의 건축물에 대한 분석을 하였다. 이 분석의 결과를 토대로, 현재 시행 중인 녹색건축 인증제도에 대해 네 가지의 논점을 도출하였다. 논점 1, 조경분야의 평가항목인 생태분야는 이산화탄소 저감에 확실한 성과를 보이는 항목이다. 이에 생태분야는 8개의 건축물에서 필수평가 항목으로 평가되어야 한다. 논점 2, 조경분야는 전문성이 매우 뛰어난 분야이다. 타 분야에서 조경분야를 평가한다는 것은 올바른 평가를 저해하는 요소이다. 그러므로 생태분야의 평가는 조경전문가에 의한 평가를 하여야 한다. 그리고 타 항목 중 "기존대지의 생태학적 가치"의 평가와 같은 조경분야와 밀접한 항목의 평가는 조경분야에서도 평가에 참여하여야 한다. 논점 3, 조경 식재에 의한 에너지 저감 및 온도저감의 우수성은 많은 선행연구에서 밝혀졌다. 이에 조경 식재의 에너지 저감에 대한 평가항목이 추가되어야 한다. 논점 4, 유지 관리분야에 수목관리항목이 신설되어야 한다. 2013년 "녹색건축조성지원법"이 제정 시행된 녹색건축인증제도는 건축물의 이산화탄소 저감을 위한 실효적인 제도임에 틀림없다. 이 법은 특별법의 성격으로 건축법의 우위에 있어, 건축물을 건축하기 위해서는 꼭 지켜야 하는 법이다. 이러한 법 체제 아래 건축분야에서는 이 법과 관련된 많은 연구 및 다양한 제품의 생산으로 건축의 또 다른 먹거리 창출에 기여하고 있다. 그러나 조경 분야에서는 "녹색건축조성지원법"에 대해 건축 분야에 비해 관심이 저조하였던 것이 주지의 사실이다. 녹색건축인증제도에 대한 조경분야의 지속적인 연구가 수행되어야 할 뿐만 아니라, 조경 산업계에서도 더욱 큰 관심을 가져 이와 관련된 제품의 생산 등으로 조경의 업역 확대가 이루어져야 할 것으로 사료된다.
