Currently, building energy has received much attention and many policies for ESCO business to minimize building energy were suggested in Korea. ESCO business, or energy retrofit business for existing buildings, hardly expanded in Korea. In this study, the state of the art for ESCO business will be reviewed.

Recently, energy saving in building sector is of great important to meet national CO₂ reduction goals in Korea. In this sense, it is crucial to improve the energy performance for existing building. The energy efficiency investments, ESCO business, can be beneficial to expand the chance of energy retrofit for existing building. However, ESCO business hardly expand in Korea because it has many limitations in guarantee for energy saving. Also, it is more difficult to apply the energy retrofit measures in existing building than new building. Therefore, the retrofitting methods for existing small-and medium-sized buildings should be improved to initiate ESCO business and expand it in Korea. In this study, the energy retrofit methods for small sized office building were suggested and the case study for a small sized office building located in Suwon was accomplished.

In recent years, building energy has received much attention and there are many support system to reduce building energy consumption. In addition, It is clear that encouraging to energy efficiency investments can be benenficial to our society, because of the energy supply instability and higher energy price in Korea. Nevertheless, ESCO business, represent the existing building energy retrofit business, hardly has not expanded in Korea. besides, in the case of existing building, it is more difficult to achieve the energy retrofit measures than new building, due to the existing buildings have attributes such as a long life and a lt of energy factor, etc. Therefore, for activate ESCO business and expand ESCO business target to small-to-medium building, it is needed to optimization of retrofitting methods for existing small-to medium buildings in Korea. this research was to derive energy retrofit methods through the energy audit and analysis performed for a small -to-medium building located in Suwon, Korea.

Recently, energy retrofit is performed for existing buildings in developed country. When energy retrofitting methods are applied, the effect of energy saving should be evaluated with standardized method. In this study, the measurement and verification(M & V) methods to evaluate the energy saving effect after building retrofit was reviewed. In this paper, especially, the calibrated simulation method as a performance verification method was accomplished for the target building. The considerations to set up the baseline simulation model was described and the validity of the baseline model was analyzed with field measurement results based on ASHRAE Guideline.

Today, the energy use in buildings occupies about 23% in total energy use in Korea. The increasing rate of building energy use is more higher than those of other industry. To accomplish the national target for CO2 reduction in Korea, reducing the building energy use is very important. It is essential to strengthen the thermal resistance of building envelope for minimizing the building energy demand. In this study, the field measurement method for thermal performance of building envelope was proposed.
