Analysis of the Current Scoring Distribution by Evaluation Criteria in Korean Long-Life Housing Certification System Cases

Abstract

Peoples lifestyles are diversifying due to an increase in the types of residents housing and family structures. The ratio of apartment housing in Korea was 59.9% (9806 households) in 2015, and this type accounts for the largest ratio among all housing types. However, the life of the physical housing is approximately 30-40 years, which is relatively shorter in comparison to that of overseas houses. Therefore, the certification system for long-life housing, which had longer social and physical service life, was newly established in 24 December 2014. However, all apartment houses only acquired the normal grade (grade 4). The purpose of this study is to investigate all long-life housing certification cases and analyze the acquired score and status of each evaluation item. The total number of certification cases was 283, and the data analysis and FGI (Focus Group Interview) investigation method were used as the methods of study. As a result of analysis and summary, 173 cases (61.13%) received 50 points and 106 cases (37.46%) received 51 points. All these cases were considered normal grade. The result of this study is as follows. First, a system to maintain the long-life housing certification system operation agency is necessary. Second, the reason for an item with no score was the evasion by construction companies due to an increase in both the construction expense and sale price. Therefore, various incentive plans are necessary and should be executed accordingly. Third, it is necessary to improve the detailed evaluation standards of the certification system and reexamine its scoring system. Long-life housing is a housing type in preparation for changes in the residential environment in future. The significance of this study is that the content shall be utilized as preliminary data for improving the system through the analysis of evaluation items in the certification system.

Traps and Opportunities of Czech Small-Scale Beef Cattle Farming

“…Figure 2 shows the main drivers and feedbacks The whole process started with interviewing farmers [4,57]. For these purposes, we applied the focus group interview method [58], which is well suited for a sample population with homogeneous characteristics [59]. Addressing the topic by the focus group interview method elicits the interaction and discussion, which strengthen the quality of generated responses [60,61].…”

Effect of Subsidies and Tax Deductions on Promoting the Construction of Long-Life Quality Houses in Japan

“…The above-mentioned implications (i.e., providing economic incentives) may also be applicable to other countries with regard to increasing the amount and share of sustainable housing. In particular, subsidies/tax deductions are important for promoting this type of housing in countries with short average house lifetimes (similar to Japan), such as Korea [ 21 ]. However, because characteristics (e.g., response to economic incentives), situations (e.g., economic situations), and policy systems (e.g., subsidies and taxes) differ by country, similar analyses are needed for other countries to further understand and confirm the factors that promote sustainable housing.…”

“…For example, Park and Tae [ 20 ] compared the housing policies of 10 countries on three aspects related to the quality of housing and offered policy suggestions to improve the quality of housing in Korea. Other studies include an evaluation of the scores and status of housing under the certification system for long-life housing in Korea [ 21 ], an evaluation of the lifecycle CO 2 emission reduction of long-life apartment housing in Korea [ 8 ], the development of regulations for Taiwan’s sustainable building (open building) [ 22 ], and a survey of stakeholders’ preferences for the “soft” features of sustainable and healthy housing in the UK [ 23 ]. In addition, a similar housing concept (e.g., sustainable housing) has also been studied from various perspectives, but the focus has been on design [ 24 , 25 ], affordability [ 26 , 27 ], community [ 28 , 29 ], urban construction [ 30 , 31 ], climate change mitigation [ 32 ], and energy savings and consumption [ 33 , 34 ].…”

Applying Kano Two-Dimensional Quality Model to Build the Performance Evaluation Indicators of Long-Life High-Quality Condominiums

“…Minami (2016) argued that the concept of open building will play an important role in Japan's future [1]. Kim and Hwang (2017) indicated that long-life housing is a housing type in preparation for changes in residential environments in the future; long-life housing certification is evaluated in accordance with the total scores from the evaluation of each performance, as based on the durability, flexibility (the support and infill is evaluated for variability), and maintainability in Korea [14,15]. With the development of information technology and construction methods, combining open building concepts with building information modeling (BIM) techniques can be feasible to resolve the problems of sustainable renovation of old existing housing buildings [16,17].…”
