The recent international focus on the environment has resulted in eco-friendly “green buildings” emerging in the construction industry. Green remodeling has been used in South Korea to address the energy crisis and to mitigate greenhouse gas emissions. The government aims to reduce greenhouse gas emissions by pushing for green renovation that improves buildings’ energy performance. The purpose of this study was to investigate consciousness about green remodeling and suggest trends in green remodeling through a literature review and user survey. The results indicated that respondents did not fully recognize the concept and current policies in the field of green remodeling. Green remodeling can offer energy and management cost savings in the field of housing construction. Most respondents took a positive view of the effectiveness and future prospects of green remodeling. Respondents were very interested in electric energy and natural light and considered natural lighting, insulation, and solar powered heating as important elements for current green remodeling practices. We suggest the following. First, information and public relations offerings about green remodeling are needed to raise awareness regarding the importance of green remodeling for the public as well as for experts. Second, green remodeling needs to be actively applied to both private construction and public construction. Thus, green remodeling guidelines should be developed according to buildings’ purpose, size, and form. Finally, the effectiveness of green remodeling elements is influenced by user behavior, so there is a need to educate residents about energy saving methods and equipment use. This study is expected to serve as a basis for future pilot projects for green remodeling of housing.

The Green-Remodeling Certification is a part of the Green Standard for Energy and Environmental Design(G-SEED). It aims to raise the public awareness of Green-Remodeling and to reduce greenhouse gas emissions by improving the energy performance of existing buildings. Therefore, the government has added Green-Remodeling evaluation system to the G-SEED since September 1, 2016. However, the Green-Remodeling Certification doesn"t have systematic and objective indicators, and the certification status is very low because it lacks the certification system and is not reflected in the policy and market situation such as the green remodeling interest support project which the government is promoting. Therefore, first of all, this study will analyze the status of green remodeling certification standards and draw out the problems. In addition, tis study is going to the improvement direction of the criteria of management, the detailed evaluation standard and the evaluation method are set up for the Green-Remodeling actively. As a result, this study will be utilized as the basic data on the improvement plan of the Green Remodeling Certification System.

As green remodeling was selected as one of the top 10 tasks of the Korean version of the Green New Deal, the “public building green remodeling project” is in progress. Currently, research on technology applied to green remodeling and energy performance improvement accordingly are being conducted in various fields, but it is difficult to find a case of energy performance improvement comparable to zero energy buildings. Therefore, this paper introduces the first case of acquiring the zero-energy building certification as the “public building green remodeling project”, and by comparing and analyzing the applied technology and the energy performance with the performance before remodeling, confirmed the energy-saving effect and the possibility of achieving zero-energy buildings through green remodeling. Various passive and active design techniques were applied to the target building. Through this, the energy consumption of 49.10% was reduced compared to before remodeling. An additional 40.58% of energy consumption was reduced through the new and renewable energy technology, and the Energy Self-Sufficient Rate was 79.27%. The target building acquired 30.3 kWh/m²·y of primary energy through green remodeling and obtained the building energy efficiency rating 1+++ grade and the zero energy building 3 grade. As a result of the application of passive, active, and renewable energy technology elements compared to before remodeling, annual energy prices were reduced from 6,617,136 won/year to 935,523 won/year, reduced 5,681,613 won/year.

Green-remodeling is to improve the energy performance of existing buildings that have been aged for more than 15 years since completion. In order to achieve the national greenhouse gas emission reduction plan in the building sector, it is necessary to analyze the carbon reduction effect by considering the internal carbon emissions that may occur during green-remodeling of old buildings. This study analyzed the effects of energy reduction and carbon emission reduction when green-remodeling was applied to old health centers constructed in 1992. When applying green-remodeling, the carbon emission reduction effect considered the embodied carbon emission of the improvement items and the carbon emission at the building operation stage. When applying green-remodeling to existing buildings, energy consumption was reduced by 39.3%, and carbon emissions were reduced by 48.9% after 27 years of greenremodeling. In order to reduce carbon emissions, it was important to apply a renewable system as an item to improve the performance of green-remodeling. In particular, it was confirmed that it is very important to consider the photovoltaic system as a top priority for the carbon emission reduction.

Energy performance evaluation before and after gree remodeling is important for effective green remodeling, and analysis tools and programs are used for this. This study aims to develop programs and verify performance that can be easily used by users without expertise, can be applied to non-residential buildings, and can support accurate energy performance analysis and decision-making during green remodeling. For accurate energy analysis, EnergyPlus, a verified energy analysis program, was installed inside the program as an analysis engine. The user mode may be divided into a general user mode and a professional user mode. In addition, the input method was optimized using a database. The energy analysis performance was verified by comparing the simulation results of the program developed for buildings that have been actually remodeled with the simulation results of EnergyPlus. As a result, there was an error of 4.7% in annual energy use before green remodeling and 8.9% in annual energy use after green remodeling. It is suitable for evaluating energy usage before and after actual green remodeling. However, it seems that there is an error in energy performance analysis due to differences in the process of modeling the shape of a building. Therefore, it is necessary to supplement and improve the program by conducting verification on buildings of various sizes and shapes in the future.
