Recently, an international oil price shows fluctuation in 70 dollars per barrel and it is said that this trend is able to continues for much longer. Because energy consumption in buildings accounted for about 25% of the nation's total demand for energy, Energy censervation and efficiency of buildings were very important issues. Main political measures relating to building energy use and saving were 'the system of accrediting green building', 'building energy certification system', 'energy consumption efficiency rating indication system', 'building energy code', 'high efficient energy materials certification system'. This paper presents approaches to improve building energy efficiency policy.

Green building certifications are being adopted widely, and existing research continues to show an array of benefits to stakeholders of green certified buildings. However, little attention has been paid thus far to the effects these buildings may have on their surrounding neighborhoods economically. This research examined the effect of LEED and/or Energy Star certification on the neighborhoods surrounding certified office buildings from an economic standpoint with spatial and statistical analyses. This research showed the unit market value of LEED and/or Energy Star certified office buildings and the parameters of LEED and/or Energy Star certification had statistically a positive impact on the median unit market value of their neighborhood areas. The findings can provide useful insights into the possibilities for additional economic benefits of their neighborhoods, encouraging a win-win approach that enhances the local real estate market.

This study analyzes the average acquisition ratio between the 1st and 4th grade and the distribution and characteristics of the acquisition between the assessment items based on the case of Green Building Certification System(GBCS) for the educational facilities on the university campus. By evaluating the difference between the best scored grade (Green 1st Grade) and the general grade (Green 4th Grade), we classified the cases where the difference between grades with little or big difference. By doing this, we were able to analyze the trend that were difficult to distinguish between difficult to score and an easy task. G-SEED should be used not only as a formal system for certifying certification, but also to provide environmentally-friendly technology for buildings as well as meeting market needs. To do this, it is necessary to further refine the evaluation criteria. In addition, it is necessary to establish a qualitative evaluation system by providing detailed criteria for items that are not distinguishable among grades. It is expected that this study will be used to improve the detailed evaluation items by analyzing trends in the average acquisition rate presented in this study.

In the 21st century numerous universities continue to have an interest in building a more sustainable campus. The concept related to sustainable development and sustainability is applied to new master plan of university or university building planning. The field of sustainable development can be conceptually broken into three constituent parts: environmental sustainability, economic sustainability and social sustainability. The realization of sustainable development will become when considered eco-friendly life of users, not only environmentally friendly technologies. This study aims to research the method of sustainable access to university building planning in Europe and Canada. First, certification and standards will focused on acquisition Green Building Certification. Then we look at trends of sustainability based on users and community through the system of prior consultation between university and users. For the desirable development of the sustainable campus, the sustainable planning of campus should be investigated with campus community, members and local residents considering the generation, the preservation, the maintenance of existing building.

Hazardous chemicals emitted from building materials and furniture have led to social problems such as sick house syndrome. Test methods for the evaluation of pollutant emissions from furniture-like products have been applied using various national and international standards and classifications, but they are not currently unified. This research has been done to organize the various standards and certification methods and to make new classification systems. Proper test methods have been proposed, tested, and analyzed through this research.

As a core policy for achieving the goal of reducing greenhouse gas emissions in the building sector, Korea has enforced the mandatory certification of zero energy buildings for new public buildings from 2020. This study suggests energy-saving technologies and economic factors that building officials can refer to for decision-making on the implementation of zero energy buildings. For this study, the construction cost for the energy item of a building was analyzed by collecting the building energy efficiency level certification data and detailed construction cost statement data from public institutions for the last three years. Based on the building energy efficiency certification data, each energy item of the baseline building was derived, and the energy performance of the zero energy building was derived through repetitive simulations by gradually increasing the energy performance value of the baseline building. By applying the analyzed construction cost, the construction cost for each energy item of the baseline and zero energy buildings was derived. As a result, the lighting equipment contributed up to 10.5% energy savings, and the increase in construction cost of the cooling and heating system was at least 9.1%.

The improvements of G-SEED standards was studies in this research by comparing the composition, rating scores, and standards, including categories, issues and criteria of BREEAM in the UK. In this research, it was found that both certification systems had very similar composition and rating system, however, there was slight difference in the points of emphasizing the standards due to the differences in social awareness of green buildings in each country. As a result of the detailed comparison of both standards, in addition, it was found that almost half of criteria had different evaluation approaches such as evaluation methods and scopes between both standards even though they had same evaluation objectives; some of the differences were due to the social or cultural differences between the countries, and the others were not. Through the research, we were able to derive some criteria that need for improvements of G-SEED considering the domestic conditions in Korea.

Recently, Construction industry has been trying to reduce environmental loads reflecting the global trend 'Green Growth'. Internal and External countries are provided 'green building certification', 'relevant law/regulations', 'guideline to life cycle', however, construction phase has been overlooked though environmental loads occurred intensively in this phase. Therefore, this study intend to deduct components reflected the guideline in construction phase and assess them quantitatively. The basis data is collected through survey targeting construction managers and related researchers and analyze these data using Analytic Hierarchy Process.

This study developed a verification and certification method of technologies of green infrastructure (GI) and low impact development (LID) that gained interest recently. The outdoor testbed used in this study consisted of a building type, a road type, a parking lot type, a rain garden type and a bioretention type. Indoor test facilities were ready for testing using hydrology efficient analysis, pavement and soil analysis and water environment analysis. The development of outdoor and indoor test facilities were used to certify the efficiency of GI & LID technologies, and this was expected to contribute to the activation of the related projects by providing reliable data for the application of GI & LID techniques.
