Abstract
The Korean government has established a national plan for the promotion of zero energy buildings to respond to climate change and energy crises. To achieve this plan, several energy efficiency policies for new and existing buildings have been developed. The Building Energy Efficiency Certification System (BEECS) aims to promote the spread of high energy-efficient buildings by evaluating and certifying building energy performance. This study discussed Korean building energy efficiency policies and analyzed especially the influence of the BEECS on the actual energy consumption of a residential building and calculated energy performance of non-residential buildings. The BEECS was evaluated to have influence on gas and district heating consumption in residential buildings. For non-residential buildings, a decreasing trend was shown in calculated primary energy consumption in the years since the BEECS has been enacted. Appropriate improvements of the certification system were also discussed by analyzing relationship between building characteristics and their energy consumptions.
Highlights
Buildings are a major end-use in global energy markets and will continue to be a source of increasing energy demand in the future [1]
Europe has been leading the efforts in this area, mandatory or voluntary certification systems have been introduced in many countries throughout the world [5,6,7,8,9,10]
The Building Energy Conservation Code (BECC) as a regulation and the Building Energy Efficiency Certification System (BEECS) as a certification system were briefly overviewed in this part
Summary
Buildings are a major end-use in global energy markets and will continue to be a source of increasing energy demand in the future [1]. Over the last few decades, energy performance certification has been introduced to the commercial and residential building sectors as a key policy instrument that can assist governments in reducing energy consumption in buildings [6]. This certification provides consumers with information on buildings, either in relation to achieving a specified level of energy performance or in comparison to other reference buildings [6,7].
