  • The aim of this study is to evaluate current policies and suggest the way of overcome financial impediments to the energy efficiency function of residential buildings. Based on this analysis the paper enumerates policy recommendations for enhancing how energy efficiency is addressed in building codes and other policies for residential buildings. For achieving this goal, this study conducts the cost-benefit analysis to measure total energy savings and associated total cost. The results of study shows that the cost is greater than the benefit from 1st to 4th year but the benefit will be greater than the cost for the rest of the year. In addition, this study designs a financial support method and an implementation mechanism. Investment from the capital market will take place with the government's interest subsidy. Home retrofit will be undertaken with low interest rate with 2.5% and the return will be paid by a monthly energy bill. The results of this study provides some useful insights for the policy design, including the importance of developing information tools for providing appropriate information to households.

  • Objectives: Since 1991, nationwide massive neonatal screening program for phenylketonuria (PKU) and congenital hypothyroidism have been performed in Korea. As in many other countries, efficiency of this program has not been definitely concluded. For the purpose of evaluation of this program, from the perspective of efficiency, a cost-benefit analysis was carried out. Methods: Costs of the detection and the treatment program were compared with the projected benefit(avoided costs) that results from the prevention of the mental retardation associated with the disorders due to PKU and hypothyroidism. Costs and benefits were discounted at an annual rate of 5%, and duration of life-long labor was assumed to be 30 years. Cost and benefit were estimated based on the detection rates of one case of PKU per 5,572 and one case of congenital hypothyroidism per 32,554 babies screened during 1991-1997. Results: The benefit-cost ratio was 0.418. The sensitivity analysis for the discount rates and labor durations showed that most cost-benefit ratios were lower than one(1.0) except when discount rate was changed to 3% and detection rate to two- or threefold and/or labor duration to 40 years. Conclusion: The result of this study suggested that present program of mass screening for PKU and congenital hypothyroidism could not be justified in terms of efficiency. It doesn't coincide with the results of previous studies in major developed countries, presumably because of difference in detection rates and welfare cost for the disabled.

  • This study was conducted to analyze Korean companie's perception in IT investment cost-benefit analysis(CBA), and to see if various user group's perception is different. Literature was reviewed to classify and define variables in IT CBA, and questionnaire was distributed to CEOs, CIOs, IT managers, and general managers in Korean companies. Respondent's priority ranking in IT CBA was shown to be tangible benefit, direct cost/intangible benefit, and indirect cost/risk. Data analysis showed that Korean companie's actual practice in CBA was generally aligned with their perception. User group's(Executives vs. mangers, and IT managers vs. general managers) perception was not shown to be statistically different. Survey result also showed that IT CBA was not well practiced in the companies although respondents perceive the analysis very important. These findings suggest that more education and practical experience is needed for Korean companies to perform IT CBA.

  • Rockfall mitigation methods have been widely constructed along railway lines but aren't estimated with any economic analysis methods up to now. Therefore, this study applied a benefit-cost analysis to rockfall mitigation method to determine whether it is indeed an economically efficient construction. The Benefits were estimated based on data collected from disaster history, and included three types of benefits that are originated by reduction of train accident, train delay and rockfall removing cost. The costs included both construction cost and the maintenance cost of the selected method. This analysis could clarify the investment effect of rockfall mitigation method that would be built at rockfall prone slope.

  • The research institute has a function to get the research outcome through the various experiments, data collection and analysis. Therefore, research building is important to keep the research condition or experiment environment. But buildings would be deteriorated and leaded into the deterrence of research. Maintenance is planned to protect the research building condition through various general repair or heavy repair. The heavy repair is generally conducted in massive repair scope or main components preparation. In this paper, it aimed at analyzing the effect of the massive or main components repair with inputted cost and its resulted output. In order to analyze the effect of a massive repair, it used the Benefit/Cost analysis and sensitivity analysis. Results of this study are as follows : The benefit/cost analysis shows that research building whose researcher continuously live and study has good effect. On the contrary, pace of the the experimental function is not good effect in benefit/cost analysis. But the experimental function is indispensible to get the research outcom for the research goal. Therefore, the experimental function will be planned to repair and get the historical repair data because the proper repair time would be prepared to cut down the repair cost.

  • This study aims to analyze the benefit-cost of the cleaning device for photovoltaic power generation systems in buildings in order to check its economic feasibility. A product, which has similar characteristics to the ultrasound-based cleaning device and is widely used in South Korea, was selected to compare with the benefit-cost value of the ultrasound-based cleaning device in this study. In order to quantitatively and qualitatively analyze benefit and cost aspects of the two products, categories and evaluation factors of each aspect as well as evaluation criteria were identified. Based on the identified evaluation factors and criteria, this study conducted face-to-face interviews with 15 experts to measure weights of benefit and cost aspects of the products. As the results, the total benefit weight of the ultrasound-based cleaning device was larger than its total cost weight since the benefit-cost value was greater than 1, which was 1.6 times of that of to compared product. Therefore, from the economic perspective, it is worth to develop the cleaning device for photovoltaic power generation systems applying ultrasound technology.

  • With the increasing obligation to reduce greenhouse gas emissions to the building sector, the government has been gradually expanding its obligation to zero-energy buildings since 2020. Since the ZEB certification took effect in 2017, 48 preliminary and main certifications have been completed as of March 2019, and most of them are public buildings or even certified, but have earned Grade 5 of ZEB. This means that compared with the number of annual building permits registered in Korea, the figure is insignificant, and that it receives little if not mandatory. Therefore, this study investigated empirical cases of ZEB additional construction cost and conducted cost benefit analysis according to changes in ZEB additional construction cost based on a preliminary feasibility analysis project recently conducted by the KDI. In addition, considering the public buildings, the social costs were considered, and the cost-benefit analysis method was the same as the KDI's preliminary feasibility analysis method. The analysis shows that if the ratio of ZEB additional construction cost is more than 5 percent, it is analyzed that there is no economic feasibility, and considering that the ratio of additional construction cost in the cases of ZEB in Korea is 17 percent to 38 percent, it will not be easy to obtain ZEB certification in terms of cost. Finally, to narrow these differences in cost and economic aspects, the overseas low energy and ZEB incentive examples proposed measures such as the concept of subsidy payment in Illinois and the compensation of social costs to private ZEB.

  • Although the NutriPlus program has shown considerable evidence of enhancing users' nutritional status, the budget does not cover all eligible mothers and children. This study aimed to conduct a cost-benefit analysis of the NutriPlus program to assess its economic efficiency. 53 families with 79 users in the NutriPlus program at Daejeon Dong-gu Health Center participated in this study with informed consent. The costs and benefits were estimated from both the administrator's and users' perspectives. We converted the time cost into Korean currency based on the minimum wage in 2014. The value of nutrition education and service (B2), estimated by contingency valuation method (CVM), was counted as an economic benefit. 6 families (11.3%) were recipients of national medical care and 22 families (41.5%) paid 10% of the food package cost by themselves. The total cost was \7,450,167 and the total benefit was \12,402,239. The budget for the health center (C1+C2+C3+C4) was \5,984,381 a month. Time and transportation cost for receiving nutrition education (C6) differed significantly according to the economic status of families. Household food consumption increase (C4-B4) was 40,379 in the poverty group, which was four times more than in the other groups. The net benefit (B-C) was \4,852,172 and the B/C ratio was 1.66. Therefore, the NutriPlus program is beneficial in the economic aspect as well as in the nutritional aspect. If the enhancement of nutritional status was also considered, the total benefit would be even higher. These results confirm the legitimacy of a secure budget for the NutriPlus program. And we suggest expanding its budget to cover more eligible individuals to improve people's health and welfare.
