A variety of Certification systems are initiated, as increased demands for housing quality of building & house owner. New building and apartment built in Seoul metropolitan should acquire Building Energy Rating System and Housing Performance Grade indication System, Green Building Certification System. Building Energy Rating System could be acquired through the certification from energy performance index of environment grade in Housing Performance Grade Indication. Between Housing Performance Grade Indication and Green Building Certification System, There are troublesome to acquire certification because a lot of assessment items are overlapped. At a result, the rational and efficient certification system should be initiated not only to avoid overlap among those certification systems and promote Green Building market share but also efficient certification system operation. We will discuss on assessment items between Housing Performance Grade Indication System and Green Building Certification System and release the improvement method those Certification Systems to avoid overlapping to assessment items.

New and Renewable Energy Equipment Certification program has been integrated into the KS(Korean Industrial Standards) certification system as of July 29, 2015. This study is to determine whether the KS certification requirement has had a positive effect on corporate performance (e.g. quality improvement, financial result, customer satisfaction) within those that had already acquired the New and Renewable Energy Equipment KS certification. As a result, among the requirements for the KS certification, quality management, product management, and product testing have a positive impact on product quality improvement, and product testing has shown a positive influence on customer satisfaction. Although requisite for the KS certification did not have a significant effect on financial outcome such as increase in revenue, it has shown to have positive consequence to some extent on those firms that newly obtained the certification.

A various building certification systems are being enforced in Korea. However, the enforcement of many building certification systems has brought on the concerned people's confusion and the operation of various building certification systems which have similar assesment items causes much time and economical losses. Therefore, in this paper, the features of the GBCS(Green Building Certification System), Housing Performance Indication System, Building Energy Rating System, and Green Home Standard and Performance Evaluation System are compared and the correlations among each building certification system are analysed. As a result, it is presented that a considerable number of assessment items were so similar and identical that integration of building certification systems is needed for effective operation of these systems.

Presently, various building certification systems are being enforced in Korea. However, people are in confusion and have an aptitude to waste time and money because these certification systems for buildings have very similar criteria. After investigating the foreign certification systems and domestic certification systems for the building, it is required that some of similar building certification systems are integrated.

Purpose: G-SEED's evaluation of existing buildings in Korea is an important point because the energy consumption and CO2 emissions of existing buildings are continuously increasing due to the aging of buildings over time. In 2016, the government has set up a 'Green Remodeling Certification Standard' in G-SEED in order to revitalize the green remodeling business of existing buildings. As a result, G-SEED is distinguished between buildings with green remodeling and buildings with general remodeling. Therefore, this study analyzed the system of the certification of the green remodeling building which is aimed at improving the performance of the building. Method: First, we analyze characteristics of the existing building certification standards of G-SEED(Korea), LEED(USA), and BREEAM(UK). Second, the evaluation criteria are based on the G-SEED Green Remodeling Certification, 2016, LEED for BD + C: New construction and major renovation v.4, BREEAM UK Non-Domestic Refurbishment and Fit-out 2014. Based on the analysis results, we propose the improvement direction of G-SEED Green Remodeling Certification Standard. Result: Existing buildings should be classified into 'existing building certification' for re-certification and 'green remodeling certification' accompanied by building performance improvement. In addition, building green buildings through performance improvement should include not only energy performance, but also creating a pleasant indoor environment and minimizing environmental impact. Finally, existing buildings have accumulated information on energy and resource use, and a performance improvement plan should be established based on this information.

Many government in the world have conducted building energy performance certification program to reduce building energy consumption. In this study, a reference building and its HVAC system was modeled, and the energy load and consumption were estimated by the ECO2 program. The software is a simple building energy simulation program based on monthly calculated method. The building energy efficiency rating the the reference building was 1+ under baseline condition. The simulation results showed that the insulation performance slightly affected building energy load and consumption, but light density had a significant effect on them. The application of geothermal heat pumps gave improvement of building energy efficiency rating but it could not make it possible to get zero energy building(ZEB) certification. The ZEB 5 certification could be achieved by using photovoltaics, however getting better grade was difficult. The simulation results showed that the ZEB 4 certification, one grade higher than ZEB 5, could be attained by using more than one renewable energy source such as geothermal and solar energy in this study.

Purpose: The first grade of Korea's Building Energy Efficiency Rating System(BEERS) is required for new government office buildings as a mandatory measure to reduce greenhouse gas emission. However, there is no specific criteria about performance that which level should apply to energy-saving design element for obtaining Building Energy Efficiency Rating 1st grade. Therefore, Certification status should be analyzed firstly, about the office building which is certificated. Certification analysis for office buildings acquired certification therefore should be done first. Method: In this study, Certification status(Office buildings acquired Building Energy Efficiency Rating Certification)was analyzed by classified year, region, specific scale etc. And we analyzed statistically by eliciting an average value of each element influencing to the amount of energy. Result: Energy demands were gradually decreased due to revision of thermal insulation standards for enhanced u-value. Energy consumptions were different from the kind of equipment and yearly trends applied depending on the size of the building. Total primary energy consumptions were influenced by heat source types and the primary energy scale factors.

Although many certification works have been carried out since Green Building Certification was enforced in 2002, analyses of the effects and efforts to improve this system are still poor. In the certification system, the energy performance was usually assessed by Energy Performance Index(EPI) of the Energy Saving Design Standards for Buildings. However, due to the inadequacy of analyses on current situation of the Index, there are difficulties to reform it. In this research of green-certified apartments, the author examined correlations between energy performance indexes and aimed to improve the Index by analyzing the scores based on point distribution of respective fields. The average EPI score of green-certified apartments was 74.68, and there was wide variations in min 63.4 and max 90. Furthermore, the average score of energy consumption, which was allotted the most points, was 7.04 out of 12. Therefore, betterments in the Index such as reinforcement in grade ranges and adjustment of the calculation method are necessary.

With the increase in the demand for sustainable and environmentally-friendly development, Green Building Certification System came into force in 2002, Evaluation parts of Green Building Certification System are divided into land use and transportation, energy, ecological environment, and indoor environment. Alloted point for the part of energy is larger than other part, thus we can say that this part is very important to increase the green building performance. This study aims to analyze the present condition of design and construction for the part of energy in the certificated green school building. Total 40 certificated school buildings were selected and average scoring rate of each item was evaluated. Key particular to be considered were suggested to improve the item of energy consumption.
