  • Purpose: Since September 1st, 2013, subjects of the evaluation have been expanded, and the evaluation standard has been detailed to enable Building energy rating system for all buildings. Accordingly, the new evaluation program (ECO2) has been developed, and therefore, apartment applied after September 1st, 2013 were evaluated with the new evaluation program. Therefore, this research suggests the improvement plan to figure out reasons for the evaluation result calculation and to calculate the evaluation results close to the actual energy usage by analyzing and comparing primary energy consumption as a result of the new evaluation program (ECO2) and actual heating energy usage on the same building. Method: When comparing evaluation results of the new evaluation program (ECO2) and actual heating energy usage, the tendency was similar but different. Also when comparing seasonally, the tendency was similar, but the different between actual heating energy usage and primary energy consumption during winter is greater than during spring or fall, and when comparing seasonal electric usage, heating alternatives were used through increased electrical usage during winter compared to during spring or fall. Result: Therefore, when evaluating apartment with the new program (ECO2) in the future, evaluation items relevant to the use of heating alternatives should be added, and the modification factor should be added according to the region. Based on the evaluation results of the research and actual energy usage, the Modification factors of the central part and the southern part were calculated respectively as 0.5 and 0.8.

  • Enhancement of exterior's insulation performance like wall or window etc. is general way for building's energy efficient and thermal performance. But exterior's opening plan is important for minimizing the energy consumption and heat loss. In this paper, energy saving rate will be analyzed and compared considering the window area's rate and window's SC(Shading Coefficient) in a apartment with Building Energy Efficiency Rating System's evaluation tool. In the process of evaluation, energy saving rate is measured at each stage of the window area's rate from 20% to 60% every 10% term and the shading coefficient value from 1.0 to 0.6. As a result of this research, energy saving evaluation could not be measured exactly with existing evaluation tool. Accord this research, Building Energy Rating System's evaluation range is needed to be broaden for exact evaluation of energy saving rate.

  • EERE(Energy Efficiency and Renewable Energy)는 미국 DOE(Department of Energy)의 산하기관으로 에너지 효율화와 신재생에너지 정책 전반의 기획 및 프로그램 평가를 담당하고 있다. EERE에서 수행하는 평가 Tool중 가장 일반적으로 쓰이는 것은 General program evaluation(프로그램 일반 평가)인데 여기서는 크게 다섯 가지의 세부 평가 방법을 제시하고 있다. 이중 Impact evaluation은 기술 확산이론(diffusion of innovations)를 이론적 토대로 하고 있는 보급 및 R&D프로그램의 평가 방법론이다. 이는 프로그램 성과를 높은 수준으로 정량화 시킬 수 있으며 특히 외부효과들을 제외한 순수한 프로그램의 결과만을 도출하는 것을 평가의 목표로 하고 있어 실제 성과분석에서 매우 유용하게 사용된 다. Impact evaluation의 시행은 Impact evaluation framework라 불리는 일련의 과정을 거쳐 실시되는데 이것은 체계적인 평가를 돕고 평가 전반의 신뢰도를 높이는 역할을 한다. 본 연구는 Impact evaluation 방법론을 심도 있게 고찰하고 이를 통해 국내 신재생에너지 정책평가로의 적용가능성을 살펴보았다.

  • Outcome Evaluation은 미국의 DOE(Department Of Energy)산하 EERE(Energy Efficiency and Renewable Energy)에서 프로그램 평가를 위해 사용하는 General Program Evaluation Guide에서 언급된 5가지 평가방법 중 하나로 프로그램의 결과를 측정하여 평가하는 방법이다. 이는 프로그램을 시행한 후 일정한 기간이 지난 뒤 프로그램의 목적을 달성함으로써 얻어지는 결과를 추산하여 그 기간 동안 프로그램이 의도했던 목적을 위해 얼마나 잘 수행되었는지를 보여준다. 본 연구에서는 Outcome Evaluation을 이용하여 한국에서 진행되고 있는 신재생에너지 보급사업에 대한 평가를 하였다. 현재 한국의 신재생에너지 보급사업은 크게 보급지원제도와 기반조성사업으로 나누어져 있으나 본 연구에서는 보급지원제도에 중점을 두어 평가를 진행하였다. General Program Evaluation Guide에 따르면 Outcome Evaluation의 방법론은 engineering estimation에서 survival analysis에 이르기까지 다양한 방법론을 제시하지만 본 연구에서는 Tabulation과 Correlation을 주로 활용하였다. 먼저 평가의 대상이 되는 프로그램과 시기를 정하고 평가지표를 산정한 뒤 위와 같은 방법론을 활용해 평가를 진행했고, 그 시사점을 도출하였다.

  • This study suggests 5 evaluation criteria (safety and technology, environmental impact, economic feasibility, social factors, and institutional factors) and 24 evaluation indicators for a NFC (nuclear fuel cycle) derived using factor analysis. To do so, a survey using 1 on 1 interview was given to nuclear energy experts and local residents who live near nuclear power plants. In addition, by conducting a factor analysis, homogeneous evaluation indicators were grouped with the same evaluation criteria, and unnecessary evaluation criteria and evaluation indicators were dropped out. As a result of analyzing the weight of evaluation criteria with the sample of nuclear power experts and the general public, both sides recognized safety as the most important evaluation criterion, and the social factors such as public acceptance appeared to be ranked as more important evaluation criteria by the nuclear energy experts than the general public.

  • In this study, the evaluation of environmental performance of the building energy system of domestic commercial sector was carried out. Based on the theory of linear programming model, we established an evaluation model satisfying object functions and constraint conditions. Employing the model, the evaluation of building energy system was performed under the consideration of cost and environmental constraint conditions. As an evaluation tool, MARKAL (MARKet Allocation) known as a market distribution model was employed. We analyzed scenarios of Case I (Base Scenarios) through Case IX established by the combination of the components of building energy system such as glazing, building skin, core, and heat source system. According to the results of the evaluation, highest contribution on the useful energy demand was obtained from the building energy system combined with solar heat source system, when the total amounts of $CO_2$ exhaust as an environmental constraint condition is assumed to be the level of 1995.
