In Korea, sustainability is mandatory in every field. University campuses are educational facilities that consume considerable amounts of energy. Therefore, many universities have tried to take advantage of the last opportunity to prepare students with sustainability and leadership. This study compared the green campus policy and evaluation criteria among Korea, US AASHE, UNEP, and ISCN-GULF to vitalize the green campus movement and suggest recent research data for the Korea green campus accreditation. The results are as follows: 1. new evaluation criteria need to be added to the certified green building total floor area ratio instead of adapting the G-SEED system in the Campus Resource & Environments category; 2. Korean Green Campus Evaluations need to be improved when expressing the campus individuality by choosing an increased number of credits and criteria; and 3. new evaluation criteria are required to secure the result, feedback, and products from curriculum updates in the Campus Education category.

Under the regulation of rational energy use in public institutions, it has been mandatory for educational facilities to meet the first grade or higher since 2014. Also the regulation has forced educational facilities as public institutions to use renewable energy since September 2008. Educational facilities are required to be qualified as zero-energy buildings from 2020 under the revision of the Green Building Act. In this study, we identified the current status of the building energy efficiency rating system and the renewable energy system installation for 316 educational facilities that were accredited as "building energy efficiency rating system" from February 2015 to March 2019. Also we analyzed the energy self-sufficiency rate based on energy requirements and renewable energy output. Of the 316 facilities, 12 had 1++ and 293 had 1++ for the "Building Energy Efficiency Rating System". Among the 12 facilities which had 1+++, 11 recorded ZEB level 5 or higher, and 28 out of the 293 facilities(11%) which got received 1++ had ZEB level 5. Thus, it is impossible to implement the ZEB certification system for educational facilities under the present conditions. Expanding the ratio of 1+++ and investing in renewable energy systems should be preceded.

As a key policy for achieving the goal of reducing GHG in the building sector, Korea has enforced the mandatory certification of zero-energy buildings for new buildings in the public sector from 2020. This study evaluated a policy to achieve Net Zero by identifying the trend of changes in building energy performance according to policy and presenting a methodology to analyze the current performance state of energy technology applied to buildings. The final goal was to help stakeholders apply appropriate energy technologies for new buildings. For this study, data collected on building energy efficiency certification over the last four years have shown a gradual increase in energy performance. In addition, K-means cluster analysis was used to analyze the performance status of energy technologies applied to buildings. The high and low clusters of education and office facilities were used to analyze the comparative group (2016-2020, 2020). As a result, the solar module area in both high and low clusters of education facilities increased by 261.1% and 283.5%. In contrast, the solar module area decreased by both high and low clusters of office facilities. The most passive and active technologies showed an increase in energy performance.

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.

In Korea, Green building certification system had been operated for more than 10 years and Expired certification buildings are ever-increasing. However, post management of building and qualification standard for re-certification(G-SEED) aren't exist, certificated green building don't have smoothly maintenance and management. Therefore, analysing the status and situation of similar system such as building maintenance and management, to suggest the direction of evaluation for green standard for energy and environmental design.

In this study, an analysis has been conducted on the evaluation criteria of current G-SEED(Green Standard for Energy and Environmental Design) and on the 78 buildings, certified by G-SEED, for 3 years from November, 2012 to November, 2015. Based on the results of this analysis, four issues are driven and proposed hereinafter. Issue 1 : Nowadays, the psychological proportion of landscape architecture in building is getting greater than ever so that it shows reliable reduction of carbon dioxide. Therefore, so far as the eight kinds of buildings are concerned, the evaluation items of G-SEED must include those of landscape architecture mandatorily through its enlargement. Issue 2 : It is undesirable factor that inhibits precise evaluation on landscaping area to let other areas appraise landscape architecture because it requires outstanding professionalism. So, G-SEED should not only ensure landscaping professionalism for the correct evaluation but also let landscape area participate in assessing other areas. Issue 3 : Many previous researches turned out that landscape planting technique has excellent effect on saving energy and reducing temperature of buildings. Thus, landscape planting technique of landscape area is required to be one of the evaluation items of energy sector. Issue 4 : Tree management also has to be newly included as one of the evaluation factor for the maintenance relating to the landscape architecture. G-SEED, enacted and enforced by the Green Building Creation Support Act in 2013, surely is effective system to reduce carbon dioxide in buildings. This is a special Act in its nature that is superior to Construction Law and must be observed by all means to construct buildings. Under the umbrella of this legal system, various of researches and products are contributing to creating new jobs in construction area. However, it is a well-known fact that landscape architecture area has shown less interest on this Act than that of construction area. In conclusion, it is necessary that landscape industry should conduct continuous researches on G-SEED and pay more attention to the Act enough to harvest related products and enlarge its work area.

최근 고도성장에 발맞추어 건축물의 에너지 효율등급 인증제를 실시하면서 외단열시스템(EIFS) 외장재 사용이 늘어나고 있으며, 건물의 외관상의 디자인을 중시하게 됨으로써 다양한 소재의 외장재를 적용하고 있다. 그러나 건축물의 내부 또는 외부에서 발생된 화재가 외장재를 통해 건물 전체로 확산되는 이른바 동시다발성 화재가 많이 발생하고 있다. 2010년 부산해운대의 고층건물에서 외장재를 통해 연소 확산된 화재가 발생하면서 건축물의 외장재의 관한 규제가 절실해졌다. 현재 국내 건축법과 소방법에는 내화구조 및 내장재에 관한 기준은 있지만 외장재에 관한 기준은 마련되어 있지 않다. 이에 현재 건축물 외장재의 법제화를 하기 위해서 많은 연구와 실험이 진행 중에 있다. 이런 노력에 앞서 현재 상용되는 외장재의 종류를 살펴보고 국내 건축물에 적용된 외장재에 대해서 알아보는 것이 이번 연구의 목적이다.

Recently, the international community signed a climate change agreement to prevent global warming. Yet currently, the fossil fuels have been widely used in to supply building energy for cooling and heating. The Green Building certification (G-SEED), an energy efficiency rating for new or existing buildings requires that buildings meet certain conditions. Insulation is used as a building material to reduce the energy supply to buildings and to improve the thermal insulation, and it accounts for more than 90% of the total heat resistance provided by the building surface components that meet the energy-saving design standards of new buildings. In this investigation, a performance evaluation study was conducted through an experimental study by directly extracting the foam polystyrene insulation on-site during the remodeling of a building that was in the range of 22~38 years old. Through tests, it was found that the thermal conductivity of the extrusion method insulation (XPS) was reduced by 48% and the compressive strength of XPS decreased by 36% compared to KS M 3808, which is the initial quality standard. For bead method insulation (EPS) with a thickness of 50mm, the thermal conductivity, the compressive strength, and flexural failure load were similar to the initial quality standard. Therefore, in the calculation of the primary energy requirement per unit area per year, the performance of bead method insulation can be estimated simply by considering the thickness of the insulation, while a correction factor that considers its performance deterioration should be applied when extrusion method insulation is used.
