On July 2004, the brand new CASBEE for construction (Brief version) has completed while trying to highlight and improve major items adequate for each region's characteristics in Japan; at the same time, from the start of NAGOYA CITY (operated since April 2004) to the point of May 2011, it has been mandatory for specified size buildings in 23 regions by law. Evaluation sheet of CASBEE is published on each region's home page and various genre of information on building evaluation which is scheduled to be completed by 2016 and is for 5-6 years of quantity is accumulated until October 2012. It is good study resource to verify how new buildings being evaluated are closely match with CASBEE's original purport (eco-friendly, energy efficiency, publicity etc). Particularly, for Japan's multi-family housing where small sized mid to high level single housing type is majority in city, it is an important point that improved performance on eco-friendly buildings have more value in city rather than suburb. Categorized score through evaluation is a resource to confirm the latest trend of multi-family housing built in congested city; on the other hand, demand of the time can be recognized by the score focused on category. It is meaningful resource to determine the adequacy of evaluated items and the degree of reality.

Purpose: As the concerns for the environment are gradually prioritized, increasing interests of environment-friendly buildings are drawn. The Green Standard for Energy & Environmental Design (G-SEED) has been strengthened. However, there are no specific assessment criteria that reflect the special situation of healthcare facility. UK, US and Japan have green building certifications specially designed to evaluate sustainable healthcare facilities. This study has been started in order to provide basic information for developing assessment criteria for healthcare facilities in Korean Green Standard for Energy and Environmental Design. Methods: In this study, we investigated three foreign green building certifications and compared their assessment system and criteria for healthcare buildings. Results: Each of the three foreign certification standards showed the difference in the system, but all contained the contents specific to healthcare facilities. Evaluation items were affected by regional cultural environment and also medical environment. Patient safety and integrative planning were the most important assessment contents. Implications: Based on this analysis, Korean Green Standard for Energy & Environmental Design for healthcare facilities will be developed.

The goal of this study is to compare the evaluation results of indoor daylight environment for each certification and propose improvement points. As the importance of indoor daylight environment has increased, foreign countries have been aware of this and have changed the light environmental certification items. On the other hand, Korea environmental certification systems have not been able to follow the current situation. In order to improve this, this study intended to find evaluation criteria for each category by comparing and analyzing indoor daylight environment certification items in Korea's G-SEED, LEED in the United States, BREEAM in the UK, and CASBEE in Japan. After that, this study simulated 3D models of three spaces about classroom, reading room and club room of Yanghyun elementary School which is scheduled to be constructed for the evaluation of indoor daylight environment, and the results were analyzed to suggest for improvement.

Many countries have carried out various policies about sustainable building to protect the earth against the global warming and environmental pollution. Korea government has also executed the Green Building Certification System. In order to keep the performances of certificated buildings sustainable, the effective building maintenance is quite necessary. Meanwhile, the foreign green building certification systems have considered the building maintenance as one of the most important items to keep the building performance effective. However, Green Building Certification Criteria(GBCC) of Korea has not had the sufficient criteria for the maintenance of green building. Therefore, The purpose of this study is to find direction for the improvement of management categories of Korea Green Building Certification Criteria. For this aim, GBCC was compared with the foreign certification systems such as LEED, BREEAM and CASBEE.

This study aims to propose basic data for improvements that can actively respond to climate change in the Green Building Certifications that came into effect in March 2013, including the analysis of evaluation criteria and applications. In response to climate change, Green Building Certifications in developed countries such as BREEAM(UK), LEED(USA), DGNB(Germany), and CASBEE(Japan), have been extended to the neighborhood unit or city levels, i.e., BREEAM Communities, LEED Neighborhood Development, DGNB Stadtquartiere, CASBEE Urban Development. On the other hand, for the Green Building Certifications in Korea, some criteria such as indoor environment and energy have been given more emphasis than others such as external environment(land use, traffic, ecological environment). In addition, results from the analysis of the evaluation scores on the external environment of 79 housing complexes show that the score on the indoor environment and energy determines the evaluation grade, whereas the score on the external environment is less weighted and has less impact. Therefore, the new evaluation system for the Green Building Certifications responding to climate change should be extended from building level to urban district levels.

Purpose: In this study, we analyzed the energy performance levels and high-performance technology trends through the case studies of foreign high-performance buildings. Method: Buildings built within 10 years were selected for the analysis of recent trends. we analyzed the buildings of U.S.A, Germany and Japan using LEED certified buildings, Passive House certified buildings and CASBEE certified buildings database for the case study of foreign high-performance buildings. A total of 20 high-performance buildings including 14 cases in U.S.A, 4 cases in Germany and 4 cases in Japan were selected. Annual energy consumption levels for 20 high-performance buildings were collected with the actual energy consumption data or data from simulation programs officially recognized by DOE. Annual energy consumption were compared with the energy performance standard of the office buildings in the CBECS database, ASHRAE Standard 90.1-2004 and Building Energy Efficiency Rating System in Korea. Result: The order of the green strategies applied in the main categories are Renewable Energy(63%), Indoor Environment Control(51%), Envelope Improvement(44%) and HVAC System & Control(28%). Specified strategies most widely used in the sub-categories are high-performance Insulation (70%), High Efficiency Heating, Cooling Source Equipment(85%), Photovoltaic&Solar Thermal(80%) and Daylighting(80%).

Recently, as the concern over environmental problem has been serious all over the world, carbon has become a key issue to mitigate the problem. In the field of Architecture, various sustainable assessment systems and LCCO2 assessment strategies have been developed, guiding low carbon building while planning. However, assessment system for low carbon neighborhood, which can be more efficient strategy, is still in the stage of research. In this paper, as a research for low carbon assessment system and planning guideline for neighborhood, scope meeting domestic condition has been set and sustainable assessment system for neighborhood, which is similar to low carbon concept, have been compared. LEED-Neighborhood Development, BREEAM-Communities, CASBEE-Urban Development, and GBCC-Apartment Houses were used for comparison. As a result, it is found that those systems has many differences in judging system, aggregating method, scope of evaluation, and relations with a building assessment system. The concern about carbon is not insufficient yet. Finally, assessment system for low carbon neighborhood, which is not only for establishing the plan, but also for giving guideline at the very first state of the plan, should be developed as fast as passible. With the result of this paper, establishment of assessment criteria and the way to measure quantitative $CO_2$ should be studied forward.

Green building certification is being implemented in various countries around the world for the purpose of securing sustainability and reducing energy use and carbon emissions. Korea has been implementing G-SEED, a green building certification, for buildings since 2002, but in foreign countries, the evaluation target has been expanded from buildings to neighborhood units, cities, and infrastructure. Therefore, the purpose of this study was to establish Korean green building certification system in terms of neighborhood scale. In order to make Korean certification scheme for neighborhood communities, three major international certification systems (BREEAM Communities, LEED-ND, and CASBEE-UD) were compared. Comparison was executed about definitions and goals, certification system and range, certification categories, and regulation relationship by literature review. Based on the results, the evaluation system proposal including the scope, subjects, and items for green building certification in Korea was proposed.
