Deploying new and renewable energy should be encouraged due to scarce of natural resources and to reduce the $CO_2$ emission. Regarding the Green Building Certification System, '2.2.1 new and renewable energy use', and '2.3.1 carbon dioxide emission reductions' are related to new and renewable energy. Applying new and renewable energy can achieve the score in two criteria mentioned above and most of buildings get a perfect score in the green building certification system. So these criteria needs to be revised to have discrimination. In this study, supply rate of new and renewable energy of the buildings that have achieved Green Building Certification by E Green Building Certification Institute was analyzed. The improvement of assessment criteria related to new and renewable energy is proposed and could be applied to the revisions.

Damage occur frequently around the world on climate change and the main cause of greenhouse gas emissions regulation is growing. To this end, the government has built integrated management system for national building energy. The building energy information is total 6.8 million complex. Integrated management system for national building energy database are matched building registers information and energy information of the supply agencies. However, the matching process has its limitations so advanced work is in progress continuously. This study analyzed integrated management system for national building energy database quality and limitations and deduce improvement plan to increase system reliability and availability. The existing database matching average rate is 85.6%. 58.2% of the total non-matching data type has no building information. To ensure the ease of new database matching and the accuracy of the existing database matching, address standarization and building properties system are needed between building information and energy information. Also, The system construction is required to include information on other energy sources like petroleum energy which has high proportion of non-urban areas and small residential areas and renewable energy which has high potential in development and utilization.

The proportion of old buildings over 40 years among all school facilities is about 20%. The degree of deterioration is also increasing, resulting in safety risks that reduce the residential safety of faculty and students or a poor environment that does not meet the new curriculum and educational conditions is rapidly increasing the need for repair and renovation of school facilities. In order to fully fulfill its role as a space for implementing education, school architecture requires an understanding of the national curriculum and a clear criterion for determining the relationship between education and space. In order to set the evaluation criteria for deteriorated school architecture, this study presents judgment data centered on quantification and accuracy so that relevant personnel can utilize scientific analysis, research and development of detailed and systematic comprehensive evaluation indicators, and quantified evaluation methods.

Considerable efforts have been made to reduce greenhouse gas emission around the world to cope with climate change. The government is implementing G-SEED certification to promote energy efficient building design. This study aims to verify the effectiveness of the G-SEED certification system by analyzing the actual energy use of certified and non-certified office buildings. For this purpose, the energy consumption of 135 certified and 142 non-certified office buildings was analyzed according to the seasonal characteristics, building size and number of floors, approval year, and certification grade. The energy saving effects of certified buildings was about 50% higher than that of non-certified buildings. The seasonal energy consumption of buildings is closely related to the heating degree-days. The energy consumption of certified and non-certified buildings decreases with increasing approval year. On the other hand, the energy consumption according to building size and certification grade is not related. This study provides meaningful basic data of G-SEED certification system for future improvement. As the building energy performance standards are strengthened over the years, it is necessary to make the individual score of G-SEED certified projects open to the public to configure the factors of energy efficiency.

This study was conducted to obtain basic data on efficient and eco-friendly crop cultivation for urban residents who enjoy urban agriculture as a hobby or leisure activity. We planted strawberry(Fragaria x ananassa)(S) and kidney bean (Phaseolus vulgaris var. humilis)(K) in different ratios to analyze the differences in soil environment, growth, physiology, and productivity, and to investigate the effects. Strawberry growth was optimal with S1K2 ratio, whereas the S1K1 ratio treatment showed the highest levels of physiology and productivity. In terms of growth and physiology, kidney beans tended to perform best in S1K2 treatment. The average number of productive pods was two, with a highest average value of 2.3 being recorded in S2K1 treatment planted with a high percentage of strawberries. In terms of growth, physiology, and prodctivity our findings indicate that it would be desirable to plant starwberries and kidney bean in a 1:1 ratio. However, considering the environmental characteristics of walls and rooftops, it is necessary to effectively manage crops suitable for these conditions. Furthermore, additional studies should be conducted to analyze the quality of fruits and seeds producted, both qualitatively and quantitatively in the future.
