Carbon neutrality refers to a state in which there is no global increase in CO₂ emissions due to human activities. In Korea, for carbon neutrality, green remodeling of existing buildings and customized support tasks for zero energy in new buildings are presented. Germany is showing fundamental changes in energy supply, such as applying renewable energy and higher energy efficiency from nuclear and fossil fuels, which were the existing energy sources. In this study, how Germany establishes policies for carbon neutrality at each state level and the cases applied to increase the energy efficiency of the actually applied residential complexes are analyzed based on this. As a result of the case complex analysis, it was found that the construction direction was being promoted as a zero-energy complex or a carbon-neutral complex by gradually reducing the energy demand in buildings and supplying additional energy with new and renewable energy in the low-energy building distribution in the 1990s. In Germany's ecological complex, energy standards have been strengthened from low-energy architecture to plus-energy architecture over time, and annual heating energy consumption standards and heat transmittance rates for each structure have been achieved at a higher level. The results of this analysis will serve as basic data and derivation of applicable items when planning residential complex development and remodeling of existing buildings for the domestic carbon-neutral goal in the future.

Sustainable design is getting to be controversial issue in all industries over the world particularly, in architecture as the amount of energy usage in architecture occupies 40%. Therefore, it is essential to make the standard for the sustainable design. In order to construct the sustainable design, firstly it should be considered that sustainable design elements based on natural resources to increase building energy efficiency is established and classified. The method of sustainable design divides into passive design and active design. Passive design method should be examined with active one simultaneously for more efficient usage of energy. Next, the study is followed how the sustainable design elements is adopted in buildings through the comparison of cases study of domestic and oversea. The result of case study shows similar adoption of sustainable design elements between oversea and domestic. However, the difference is shown in the building orientation and shape and the window size and position in Solar energy as well as high performance structure in Heat energy. These elements are the most significant elements in order to reduce energy load. In oversea, sustainable design is generated by architects, a client, and consultants based on the close cooperation in the beginning of early design phase before deciding building shape and envelope while in the domestic field adoption for sustainable design is conducted after deciding building shape and material. In order to design sustainable architecture more study is necessary in early stage for Zero Carbon and reducing building energy load through relation with specialists, a client and architects.

The need for zero-energy building is increasing as a means of actively responding to climate change. Since pipe insulation is a factor that minimizes heat loss of cooling and heating facilities, it is necessary to check pipe insulation standards and prepare improvement plans of preparation for certification of zero energy buildings. In this study, domestic pipe insulation standards were checked to prepare new insulation standards based on energy performance. Through the development of a pipe insulation calculation program, the heat loss according to the insulation thickness of the piping for mechanical facilities was compared and reviewed. As a result, applying the insulation thickness of the KCS standard for the same conditions increased the heat loss by an average of 10% compared to the ASHRAE standard. For this reason, it is necessary to revise the pipe insulation thickness standard in consideration of heat loss due to thermal conductivity and pipe insulation thickness. Using the program in this paper, it is possible to design pipe insulation based on energy performance and help to determine the standard for pipe insulation thickness.

제로에너지 건축물(ZEB)은 건축물 자체의 에너지 자립도를 높인 건축물로서 에너지를 생산할 수 있는 신재생 요소가 필수적이며, 건물형 태양광(BIPV)이 가장 주목받고 있는 기술이다. ZEB의 설계에서 BIPV은 설계 초기에 계획되어야 하나, 초기 단계에서 BIPV 계획은 미비한 실정이다. 이에 본 연구에서는 설계 초기 BIPV의 계획과 ZEB 자립률 검토를 위해, 3차원 설계와 빅데이터의 융·복합 설계기술인 건축물 정보통합 모델링(BIM)을 기반으로, BIM과 ZEB에 대한 이론적 고찰 및 ZEB 자립률 분석을 위한 요소를 도출하고, BIPV 에너지 생산량과 건물 에너지 소비량 산출 방법을 분석하였다. 최종적으로, 프로젝트 모델에서 에너지 자립률을 산정하고, 등급 기준을 검토함으로써, 설계 초기 ZEB의 에너지 자립률 산정에 대한 기초적인 연구 방법을 제시하였다. 이를 통해, ZEB 주체자의 의사결정을 지원함으로써 설계 생산성을 향상시킬 수 있을 것으로 기대된다.

The "Eco-friendly", "Green" concepts was began around 1992 after the Rio Environmental Summit, and the need for sustainable development globally widespread. The green building certification system was began around 2000 and the concept of green building was started in the late 1990s. The green building, which welcomes a period of radical change, is for the survival of the Earth "climate change" and reducing energy consumption in building sector. In this architecture of eco-friendly concept, the green building is rapidly expanding and existing as a ecological environment preservation. Moreover, the realization of zero energy house is to mandate for new buildings in 2025. The aim of further eco-friendly is through the prior ecosystems to restore and product energy for the 9 Green Building model houses in this paper. Building in the concept of ecology is to show about change into 7R's from the 3R's. The "Reduce", "Reuse", "Recycle" consisting of "3R's" is correlated with the traditional to the present Green Building Design. U.S. NCARB (National Council of Architectural Registration Boards) change into the concept of 7R's as "Receive", "Restore", "Respect" and "Remember", added to "3R's". In this paper, the 9 Green Building model houses do not meet the criteria of 7R's. But, the Green Tomorrow of Samsung C & T Corporation meet the 6 criteria for 7R's. This company is most comfortable at low carbon Green Building model houses. Conclusionally, introduction of eco-friendly technologies and amenities for the health of human and natural community life is to advance eco-friendly construction and enhance brand value of housing. By the way, The problem of eco-friendly architecture is initial investment and maintenance. Therefore, eco-friendly architecture and government has to try solving of this difficulty.

In responding to the recent framework convention on climate change, and the rise of the need for energy efficient buildings, such as Zero Energy Buildings (ZEB), domestic insulation standards and energy conservation regulations are being reinforced, to prevent heat loss. Accordingly, the Ministry of Land, Infrastructure and Transport have made amendments in Chapter 21 "Enforcement regulations for building facilities standards etc.", and Chapter 22 "Energy conservation standard", to reflect these changes. To effectively implement these regulations, it is required to propose air-tightness test methods, and establish air-tightness standards, based on the air leakage characteristics of domestic apartment housings. This research has been done primarily to collect basic technical data, to provide guidance for the establishment of domestic air-tightness standards for new apartment housing, through studying air-tightness test methods, field measurement on air-tightness of new apartment housings, and air leakage characteristics of major developed countries.

According to the Fourth Assessment Report of Intergovernmental Panel on Climate Change(IPCC) Working Group III, climate change is already in progress around the world, and it is necessary to execute mitigation in order to minimize adverse impacts. This paper suggests future climate change needs, employing IPCC Special Report on Emissions Scenarios(SRES) to predict temperature rises over the next 100 years. This information can be used to develop sustainable architecture applications for energy efficient buildings and renewable energy. Such climate changes could also affected the present supplies of renewable energy sources. This paper discusses one recent Fourth Assessment Report of IPCC (Mitigation of Climate Change) and the Hadley Centre climate simulation of relevant data series for South Korea. Result of this research may improve consistency and reliability of simulation weather data or climate change in order to take advantage of SRES and PRECIS QUMP. It is expected that these calculated test reference years will be useful to the designers of solar energy systems, as well as those who need daily solar radiation data for South Korea. Also, those results may contribute zero carbon and design of sustainable architecture establishing future typical weather data that should be gone ahead to energy efficient building design using renewable energy systems.
