The Korean government plans to introduce the building energy performance standard which regulates the annual energy consumption of buildings. This paper aimed to set up the reference building from database based on the building design trends for non-residential buildings. We surveyed the design data of 435 non-residential buildings which were granted building permission from 2007 to 2011. And we conducted estimation on the heating & cooling load and the energy consumption of the reference building using ECO2 program. From results, the reference building of non-residential buildings was office building which had a total 7 floors and 20,838 ㎡ gross floor area. And it suggests the design reference data of building envelope, HAVC, heat source equipment and lighting system for the reference building. The total annual energy use of the reference building was 151.9 kWh/㎡yr.

The demand side management is currently ever more emphasized with a rapid increase of energy consumption and energy-related environmental concerns such as air pollution and climate change. The Republic of Korea, which imports about 97% of its energy resources from overseas, has experienced a growing energy consumption in the past decades mainly coupled with economic growth and its trend seems unlikely to change a lot in a near future. Among other sectors, energy use in building sector increased from 22.0 million TOE in 1990 to 37.9 million TOE in 2012 at the annual rate of 2.5%. The purpose of this paper is to forecast the long-term energy demand for domestic building sector. We broke down the energy consumption by 5(residential) or 6(commercial) specific end-uses and forecast their future demands in the framework of MESSAGE, an energy system model. According to the analysis, The expected energy use for residential sector is 25.4 million TOE and that for commercial sector is 28.3 million TOE in 2035. By 2035, electricity accounts for 57% of total building sector enegy consumption and city gas accounts for 35%. For the specific end-use, space heating and hot water accounts for 40% of building energy use in 2035.

Energy is essential resource to modern society and is a key in determining whether or not sustainable development. In the energy consumption of buildings in Korea, the building sector accounts for 18.2% of a total energy consumption. The purpose of this study was to computed the energy efficiency indicator of residential building sector using national statistics as indicator factors for building energy policy. Energy efficiency indicator are composed of an energy consumption as numerator and an activity data from national statistics as denominator. National statistics data in this study were energy consumption statistic, GDP, population, number of household & house, number of residential building mass and floor area. This study proposed that house unit-based indicator (toe/house) and floor area unit-based indicator (kgoe/㎡) were useful as the energy efficiency indicator for residential building sector. These indicators can be used as a time-series trend analysis and energy efficiency criteria. Energy intensity per house unit was 1.4toe/house in 2012 and it showed a high reduction rate of 35.1% during the analysis period. Energy intensity per floor area was 13.7kgoe/㎡ in 2012 and was reduced by 55% for 1996. The graphs and charts show that the time-series trend of these energy efficiency indicator has been consistently low.

It has become necessary to study and establish policies to support the drive to increase the construction and the settlement in these sustainable buildings. the main goal of this study is to investigate domestic and foreign policies and systems for energy efficiency and environmental-friendly of buildings and to find political measurements for sustainable building. This study suggested the improvement direction about the existing systems and policies. 1) Setting medium-and long-term target of energy saving/green-house gas reduction of building and establishing a loadmap to execute them, 2) Making a systems and policies for energy efficiency of the existing building, 3) Making a systems for application and revitalization of new construction technology, 4) Strengthening eduction and publicity and introducing a various incentive systems, 5) Construction of building energy information system.

New and renewable energy systems(solar thermal system, photovoltaic system, geothermal system, wind power system) are environmentally friendly technologies and these in South Korea are very important measures to reduce greenhouse-gas(GHG) and to push ahead with Green Growth. The purpose of this paper is to analyze GHG mitigation potential by distribution of solar thermal system in housing sector with bottom-up model called 'Long-range Energy Alternative Planning system'. Business as usual(BAU) was based on energy consumption characteristic with the trend of social-economic prospects and the volume of housing. The total amount of GHG emission of BAU was expected to continuous increase from 66.0 million-ton CO2e in 2007 to 73.1 million-ton CO2e in 2030 because of the increase of energy consumption in housing. The alternative scenario, distribution of solar thermal system in housing sector had GHG mitigation potential 1.54 million-ton CO2ein 2030. The results of this study showed that new and renewable energy systems made a contribution of reducing the use of fossil fuel and the emission of greenhouse-gas in building.
