“…Traditional earthen walls (Hwangto) used in hanok have a high thermal conductivity of (1-2) W/m 2 , and the insulation effect of windows made of paper is very low [12]. Therefore, it has been shown that hanok emits the most carbon during the building operation phase of the building's life [13]. To compensate for these problems, modern materials, such as insulation and glass windows, are applied.…”

There is much discussion of the energy performance of buildings in order to carry out sustainable construction. However, buildings are not simply spaces that offer excellent energy performance, but are based on climate, culture, and context, which for sustainability are factors that also need to be considered. Hanok, a vernacular housing form in Korea, is based on organic characteristics and harmony between nature and human. Hanok aims to avoid the destruction of the surrounding ecosystem and to borrow the natural environment as a passive element. Wood, stone, clay lime and paper are mainly used as building materials. Therefore, hanok has a sustainable value that is different from its energy performance. In this context, it is necessary to analyze whether a hanok is a good space to live in, and a study on comfort performance was conducted. In this study, an analysis of the spatial comfort of Hanok was conducted. This research tried to derive performance indicators to pursue the spatial comfort of hanok that is mainly investigated through correlational analysis. The purpose of this study is, therefore, to find correlations by statistically analyzing user surveys and physical indicators, using Pearson correlation coefficient and regression analysis. This makes it possible to set preliminary standards for hanok comfort and how to consider these in the design stage.

“…Numerous studies and reports show that life-cycle assessment (LCA) methodology is currently the best framework available to assess the potential environmental impacts of any activity [1][2][3][4][5]. Proofs of this are numerous review studies that focus on analysing, grouping, and comparing other previous works focused on evaluating the environmental and/or economic impact of the construction industry under the perspective of life cycle [6][7][8][9][10][11][12][13][14][15][16][17][18].…”

Environmental and Economic Prioritization of Building Energy Refurbishment Strategies with Life-Cycle Approach

An increasing number of studies apply life-cycle assessment methodology to assess the impact of a new building or to prioritize between different building refurbishment strategies. Among the different hypotheses to consider during the application of this methodology, the selection of the impact indicator is critical, as this choice will completely change the interpretation of the results. This article proposes applying four indicators that allow analysing the results of a refurbishment project of a residential building with the life-cycle approach: non-renewable primary energy use reduction (NRPER), net energy ratio (NER), internal rate of return (IRR), and life-cycle payback (LC-PB). The combination of environmental and economic indicators when evaluating the results has allowed to prioritize among the different strategies defined for this case study. Furthermore, an extensive sensitivity assessment reflects the high uncertainty of some of the parameters and their high influence on the final results. To this end, new hypotheses related to the following parameters have been considered: reference service life of the building, estimated service life of material, operational energy use, conversion factor, energy price, and inflation rate. The results show that the NRPE use reduction value could vary up to −44%. The variation of the other indicators is also very relevant, reaching variation rates such as 100% in the NER, 450% in the IRR, and 300% in the LC-PB. Finally, the results allow to define the type of input or hypothesis that influences each indicator the most, which is relevant when calibrating the prioritization process for the refurbishment strategy.

“…According to the European Commission [16], [17] and international literature [18]- [21], the life cycle assessment (LCA) methodology is currently the best framework available to assess the potential environmental impacts of any activity. The International Organization for Standardization (ISO) adopted an environmental management standard in the 1990s as part of its 14000 standard series, with the 14040 series focusing on establishing methodologies for LCA [22].…”
