Since 1997, the Kyoto Protocol has been adopted around the world and the consensus that the need to preserve the global environment is built. And the various institutions to protect the global environment are implemented mandatorily and voluntarily. Held in Paris in December 2015 the United Nations Framework Convention on Climate Change was established in the final agreement for a new climate system established after 2020 and Korea is committed to being a more aggressive stance on global warming by setting a greenhouse gas reduction target of 37% compared to BAU 2030.
To prevent global warming of the earth which we and our descendants will live it’s an important issue to worry in all the countries in the earth. Ecological and environmental destruction caused by global warming, a situation which is still ongoing weight. The current state of global temperatures rise 1℃ than the pre-industrial level, the Paris Convention on Climate Change was adopted in an agreement to try to limit temperature rises to the width of 1.5 1℃.
The various institutions of the world have been worked to prevent global warming. The fact that the actual economical system such as carbon trading and energy consumption is in connection with the money, is much greater sense of seriousness to the global envionment. Paradoxically, applying an economic point of view to the public is more efficient to be able to realize the importance of environment, and is useful to the public to participate in global environmental protection.
In Korea, Green Building Certification started in the name of green building certification system in 2002 that has a history of 13 years this year. It has been actively operating in order to ensure the environmental performance of the domestic buildings. 4,958 buildings acquired the certification until 2014 and reach only 1,034 cases in 2014 alone, the certification is the leading system for green buildings. But the more certified buildings are expanded it is increasing awareness about the problem. Indeed are the eco-friendly green buildings demonstrating qualities that correspond? Can Green buildings be expected energy savings and carbon emission reductions to be equipped? The questions about these are being raised and now is a the time to verify the issues.
In fact there are many cases that green buildings acquire a zero point of ecological areas or high-rise buildings of curtain wall acquires a upper-grade certofications. These buildings may be environmentally friendly as well as ensure the performance of energy savings and carbon emission reductions but will not form a consensus of the socio-cultural perspective of public.
Green buildings are considering all aspects of the environment, economy, society and acquiring the public sympathy in the quantitative aspects and the qualitative aspects and shall ensure the performance of green buildings.
10 years have elapsed since green building certification system started in this country. Through the Paris Convention of Climate Change at the time of redevelopment takes place on the global environment protection policy worldwidely it is the time to amend the Korean green building certification system. Global environment is constantly changing, and recognition of people also changing according to the environmental change. Therefore, the relevant institutions will be changed to match the change of the recognition and shall serve as the leading institution that does not fall behind the times.
In order to do so, preferentially the current issues have to be resolved. To solve the continuously mentioned ploblem of the effectiveness of the G-SEED, check the environmental performance of green buildings and the exercise should be done to validate that energy savings and carbon emission reductions. It is the object of the study that solve the problems derived from verification result and provide the basic information for the certification system. The significance of the study is to contribute to environmental protection through improving the certification system.
Another problem with the current system is the adequacy of weight per item. The weight means the importance of each item. Importance varies according to the age, region, subject. As the green certification is being operating for more than 10 years there was little change in weights. So take it for granted that the change in weight is required according to the times. Analyzes the certification result performed up to now, and provides the suitability of a weight to improve the G-SEED.
In this study, the environmental performance is analyzed in terms of qualitative and quantitative aspects for the Multi-residential Building acquired a green building certification. In qualitative aspects of sustainability of a green building, analized eco-friendly performances of the building in economic, environmental and social aspects and in quantitative aspects, analyzed the environmental performance, including energy savings and carbon emission rate. The conclusion was that relationship between Green Building Certification and environmental performance was somewhat inadequate. So improvement measures proposed to complement it.
In qualitative aspect, the sectors include land use, transport, energy, materials and resources, water resources, pollution prevention, maintenance, ecological environment, indoor environment spects of the nine sectors were reconstructed by three of the environmental, economic, social aspects and adjusted the weights. In quantitive aspect, added the article of calculating the carbon emissions which is main purpose of green building construction.
By introducing the concept of sustainable development increased the effectiveness of green building certification criteria in terms of qualitative and quantitative aspects and proposed drafting amendment to establish itself as a more practical certification system. This will faithfully play a role as a representative of green building certification system policy. And will perform the leading role of the relevant institutions and contribute to the settlement as a institution that help protect the global environment.
