In December 2015, The Paris Agreement was adopted to undertake ambitious efforts to combat climate change. Korean government announced its goal of reducing the country's greenhouse gas emissions by up to 37% below business as usual projections by 2030 in 2015. The purpose of this study was to set up the calculation methodology of GHG emission($CO_{2e}$) in building sector and to estimate the annual GHG emission in building sector based on national energy consumption statistic. The GHG emission from buildings is about 135.8 million ton $CO_{2e}$ as of 2015, taking up about 19.6% of Korea's entire emission and is about 144.7 million ton $CO_{2e}$ in 2017. The GHG emission of building sector is increasing at annual rate of 2.0% from 2001 to 2017. The GHG emission from electricity consumption in buildings is 91.8 million ton $CO_{2e}$ in 2017, is the highest $CO_2$ emission by energy source. The results show that the intensity of GHG emission of residential building sector is $40.6kg-CO_{2e}/m^2{\cdot}yr$ and that of commercial building sector is $68.4kg-CO_{2e}/m^2{\cdot}yr$.

This study analyzes in detail greenhouse gas emissions in building sector. To this end, this study used data on building characteristics (including building type, region, and construction year) and monthly energy consumptions (including electricity, city gas, and district heat) for all buildings from 2015 to 2018. These data were collected from the National Building Energy Database and the energy consumptions were converted into greenhouse gas (GHG) emissions. The total amount of GHG emissions from the building sector has increased steadily from 2015 (118.1MtCO2eq.) to 2018 (132.6MtCO2eq.). On the other hand, the more recently constructed buildings had lower GHG intensities. This result shows that strengthening building design criteria was effective on the reduction of GHG emissions in buildings, and that the increased buildings contributed to increasing GHG emissions of the building sector. In addition, sales facilities are thought to have the largest reduction potential as they had the highest amount of GHG emissions and GHG intensity. This study is expected to help establish new policies for GHG reduction in building sector as well as to evaluate the effects of existing policies.

최근 유엔에 의해 전 세계 탄소배출량 중 건물부문에서 발생하는 탄소배출량이 38%로 기타 산업부문(32%), 운송부문(23%)을 제치고 가장 높다는 사실이 밝혀지면서, 해외 선진국을 필두로 건물부문의 탄소배출량을 절감하기 위한 방안으로 ESG가 적극 활용되고 있다. 국내에서도 올해 국민연금이 '투자자산 50% 이상 ESG 고려'를 발표하면서 건설업계와 자산운용사들을 중심으로 건물부문에 ESG를 도입하려는 움직임이 속도가 붙고 있다. 그러나 국내의 ESG 평가시스템은 아직까지 주로 기업지배구조와 사회적 책임 분야에 집중되어 있어 환경 분야에 대한 관심도는 선진국 대비 뒤처져 있는 편이다. 앞으로 건물부문 ESG는 10년 동안 급성장할 것으로 전망되며, 이에 대비한 다음과 같은 발전방향을 제언한다. 첫째, 인센티브제 확대이다. 정부가 환경 규제 등 건물부문 ESG와 관련한 정책을 성공적으로 시행하기 위해서는 규제 위반에 따른 임대 제한이나 징벌세 등과 같은 네거티브 제도 외에 규제 준수 시 세금 감면, 건축물 기준 완화 등과 같은 인센티브 제도를 지금보다 더 확대해야 한다. 둘째, 표준화된 ESG 기준 정립이다. 글로벌 기준과 거리가 먼 독자적인 한국형 ESG 기준을 만들기 보다는 글로벌 기준과 평가방법의 공통부분을 잘 정리하여 모든 이해관계자가 동일하게 활용할 수 있는 표준 교과서 형태의 지침을 만들어 제공하는 것이 필요하다. 셋째, 건물부문 ESG와 디지털 전환(DX)을 연계시키는 노력이다. 인력중심으로 운영되고 있는 건물부문 운영방식을 디지털화하여 지능형 중심으로 전환해야 실질적인 에너지 절감과 탄소배출량 절감을 실현할 수 있기 때문이다.

For successful outcome of real estate development projects, it is important to understand the potential tenants as they drive the demand for properties. The aim of this study is to investigate tenant characteristics of the Australian green office building sector. The specific objectives are to; (1) compare and contrast the increment trend of green buildings within the green office building sector; (2) identify the tenancy profile of green buildings; (3) ascertain the possible industry concentrations within the current green building sector; and (4) explore the relationship between green building occupants' characteristics and their tenancy. Descriptive statistics shows that Finance, Insurance and Real Estate (FIRE) industries along with government owned companies are the major tenants of green office buildings in the NSW State of Australia. In particular, real estate companies occupy more than half of the NSW based green office buildings whilst one third of them are the tenants of the 6-star rated buildings - the highest rated building in the current form of Australian Green Star accreditation scheme.

In the public sector, the number of interior construction projects is continuously increasing. When the interior construction is carried out, it is largely divided into design and construction stages. On the other hand, in order to place an order in the public sector, it requires institutional conditions such as business type, price criterion, award criteria, and guarantees. But in th case of interior design, it is necessary to establish a basis law to be applied for ordering. Therefore, this study analysed the necessity of improving the system related to the interior design order in the public sector and suggested ways to improve the system. In the future, we will continue to conduct research based on this research, and if institutional improvement is made through the proposed methodology, it will be possible to apply effectively not only in the public sector but also in the private sector.

The Law of effective building and operation for the information systems took effect at Dec. 2005. Every government and public agency have to build own enterprise architecture(EA), sometimes it's called the Information Technology Architecture(ITA), by this law. The Ministry of National Defense(MND) built the enterprise architecture(EA) during 2006. 12$\sim$2007. 11 by this law too. We knew the specific characters of the public sector thru the EA project. The public sector is less active than commercial sector and most members of the public sector are just looking on the project as a spectator. So the most of key for the success of EA is how to catch the Sponsorship and Participation of members. In this paper we propose the effective building methodology for the Enterprise Architecture of public agency applying the MND-EA. The other governments and public agencies can build own the EA easily by the proposed methodology.

One of the biggest environmental issues that our world has been facing is climate change. In order to cope with such environmental issues, the world is putting a great deal of effort into energy conservation. The building sector, in particular, consumes 36% of the energy consumed worldwide and emits considerable amount of greenhouse gases. Therefore, introduction of renewable energies in the building sector is highly recommended. Renewable energy sources that can be utilized in the building sector include sunlight, solar heat, geothermal heat, fuel cells and wind power. The wind power generation system which converts wind energy into electrical energy has advantages in that wind is an unlimited and pollution-free resource. It is suitable to be connected to existing buildings because many years of operational experience and the enhanced stability of the system have made it possible to downsize the electrical generator. In case of existing buildings, it is necessary to consider the live loads of the buildings to connect the wind power generation system. This paper, through the connection of the wind power generation with existing buildings, promotes reduction of greenhouse gas emissions and energy independence by reducing energy consumption in the building sector. In order to connect the wind power generation system with an exciting building, the live load of the building and the area of the rooftop should be considered. The installable model is selected by comparing the live load of the building and the load of the wind power generation system. The maximum number of the wind turbines that can be installed is obtained by considering the separation distance between the wind turbines within the area of the rooftop. Installations are divided into single installations and multiple installations of two different types of wind turbines. After determining the maximum installable number, the optimal model that can achieve the maximum annual power generation will be selected by comparing the respective total annual amount of the power generation of different models.

Purpose: The purpose of this study was to find out the difference in the priority level of recognition for universal design application in public spaces by gender. Method: ANOVA(analysis of variance) and post-hoc test were conducted to determine the priority level of recognition and pattern for the disabled, non-disabled, and experts classified into males and females. Results: There was no gender difference in the comparison by sector for all males and females. However, in comparing of domains and facilities, women showed a higher level of recognition than men in the building sector and cross domain. When comparing space consumers and producers by dividing them into male and female groups, women showed a higher level of recognition than men in producers, but there was no gender difference between consumers. In comparison by sector, domain and facility, women producers also showed a higher level of recognition in the road sector, park and recreation sector, sidewalk domain, four-spaces in the park and recreation sector, and six-spaces in the building sector than men producers. Also, in the building sector, women producers and consumers showed a higher recognition level than men. Comparing the disabled, non-disabled people and experts by dividing them into male and female groups, in the case of non-disabled people and experts, women showed a higher level of recognition than men, while men showed a higher level of recognition than women in the disabled. In addition, there were differences in recognition patterns in many spaces and facilities by gender. Implications: This study is meaningful in comparing the differences in the priority level of recognition and patterns between men and women to apply universal design for people of all ages and both sexes.
