“…A variety of building economics analysis methods have been proposed and applied [2,60,61]. In this study, economic analysis was used based on past economic fluctuation information, which has been used for 5 years [62] in the building industry, and can be easily understood by the end user [63].…”

The Economic Feasibility of Passive Houses in Korea

The number of passive houses and zero-energy buildings being developed is increasing, as measures to reduce the rapidly increasing building energy consumption. While government building policies focus on energy savings, investors and the building market emphasize the initial investment cost. These conflicting perspectives obstruct the development of passive houses in the building market. In this study, a series of building energy analyses, including the effect of energy saving measures and economic information considering long-term economic benefit and incentives policy, will be presented. Analyses were performed on the energy-saving measures needed to improve the performance of single-family houses in Korea to that of the passive house standard, as well as the energy saving effect and increased cost. The application of energy saving measures for passive house implementation resulted in an additional cost of 1.85%–4.20% compared to the conventional reference house. In addition, the proposed passive house alternative shows a short payback period and life cycle cost (LCC) result, compared to a conventional building’s life cycle period. The possibility of passive house implementation is high, and developing the passive house is affordable for the investor or end user in Korea.

“…For instance, Hasan et al [23] have used LCC, combined with simulation, on the optimisation of the U-values of typical Finnish constructions. In the context of PH design, several authors applied LCC as an optimisation criteria [24][25][26]. The difficulties concerning the selection of a single optimum solution after a multi-objective optimisation were discussed in Reference [27].…”

This paper discusses the thermal and energy performance of a detached lightweight building. The building was monitored with hygrothermal sensors to collect data for building energy model calibration. The calibration was performed using a dynamic simulation through EnergyPlus® (EP) (Version 8.5, United States Department of Energy (DOE), Washington, DC, USA) with a hybrid evolutionary algorithm to minimise the root mean square error of the differences between the predicted and real recorded data. The results attained reveal a good agreement between predicted and real data with a goodness of fit below the limits imposed by the guidelines. Then, the evolutionary algorithm was used to meet the compliance criteria defined by the Passive House standard for different regions in Portugal’s mainland using different approaches in the overheating evaluation. The multi-objective optimisation was developed to study the interaction between annual heating demand and overheating rate objectives to assess their trade-offs, tracing the Pareto front solution for different climate regions throughout the whole of Portugal. However, the overheating issue is present, and numerous best solutions from multi-objective optimisation were determined, hindering the selection of a single best option. Hence, the life cycle cost of the Pareto solutions was determined, using the life cycle cost as the final criterion to single out the optimal solution or a combination of parameters.

“…These days this method is commonly used in various branches of industry, in particular in power, infrastructure and construction industry (Epstein, 1996). In the literature of the subject, a lot of space has been devoted to this topic (Badea et al, 2014;Han et al 2014;Heck, 2010). Due to the fact that 85% of the costs of functioning of single-family buildings are those of energy consumption, a great deal of attention is devoted to these issues in the literature, focusing on the analysis of case studies of the use of various thermal and energy solutions and the level of carbon dioxide emissions, as an ecological boundary condition, associated with their use.…”

Abstract:In the process of making decisions on building a single-family home, many variables of a cost nature should be taken into consideration, which will affect the total level of costs of use of the building in the long-term perspective. Life Cycle Costing (LCC) is a method that can support this process, which is why the main purpose of this article is to analyze the cost of using a single-family home using the LCC method, taking into account environmental aspects that are important in shaping the quality of life of individual households and local communities. In this context, an answer to the following research problem is sought: How to calculate and reduce the costs of using a single-family home in the perspective of its life cycle, taking into account the current and prospective energy and environmental conditions? In order to accomplish the above research objectives, the first part of the article presents the theoretical basis for calculating the costs of maintaining single-family buildings together with a description of use of the LCC method. Next, a case study was presented, within which the longterm costs of maintaining a single-family building were calculated and the pro-ecological possibilities of their reduction were indicated.
