Development of Decision Support Process for Building Energy Conservation Measures and Economic Analysis

Abstract

Abstract:As policies for energy efficiency of buildings are being actively implemented, building energy performance improvement is urgently required. However, in Korea, information on measures and technologies for building energy efficiency is dispersed and concrete methods are not established, making it difficult to apply effective measures. Therefore, it is required to apply and evaluate energy efficiency measures through database construction integrating diverse information. In this study, the energy efficiency measures in the architectural sector that satisfy domestic legal standards are built. Because of the economic evaluation is necessary for the constructed alternatives, an economic efficiency database was established. The target building was set up, and energy efficiency measures were derived. In addition, a methodology that can induce energy efficient decision making of buildings was proposed, and the energy use evaluation and the economic analysis for each of the alternatives derived from applying the methodology to the target building were carried out. Furthermore, the optimal energy efficiency measures for the target building were suggested through the application of the decision-making process.

Energy Performance Evaluation and Economic Analysis of Insulation Materials of Office Building in Korea

“…On the other hand, the necessity of an economic evaluation has been con rmed when selecting energy conservation measures, and a methodology to support comprehensive decision making through economic analysis is needed. erefore, through the decisionsupport process presented in Choi's studies, which considers the energy requirements, economic evaluation, and EPI points, this study derives optimal energy conservation measures of the target building [7,8]. Figure 10 shows the derivation of energy conservation measures focusing on the U value of oors.…”

“…Choi et al [7] developed energy conservation measures (ECMs) as a basic study for targeted methodologies and decision-support system development in Korea to meet the national regulations. Choi et al [8] proposed a decisionmaking support process based on the performance evaluation results of building energy conservation measures. In addition, this study set up the target buildings, and the optimal ECM of insulation material for the target building was suggested through the application of a decisionmaking process.…”

Rethinking Participation in Smart Energy System Planning

“…Current decision-making frameworks and support tools focus on entirely different aspects, like the development and application of algorithms for renewable energy systems [7][8][9][10], the general technical architecture [11], or energy efficiency measures in individual buildings [12,13]. While these technical aspects are important, all components have to be implemented by stakeholders in practice.…”

The Development of Building Energy Conservation in China: A Review and Critical Assessment from the Perspective of Policy and Institutional System

“…Total carbon emission in China's building industry has increased from 984.69 million tons of CO2 in 2005 to 3753.98 million tons of CO2 in 2013 [6]. As policies of the building energy conservation are being actively implemented, buildings should improve their energy performance urgently [7,8]. Building energy conservation has become one of the major focuses in the energy policy systems of various countries.…”
