“…In view of user preferences, many previous studies have proposed various qualitative and quantitative methods for mining user needs. Qualitative methods focus on understanding user needs through observation, interview, and user experience analysis (Park et al, 2013), while quantitative methods have attracted more attention in recent years by using the Kano model to classify and rank user needs, which has been widely used in various fields (Juan et al, 2019;Lu & Juan, 2021;Xu & Juan, 2021). As for cost-benefit analysis, the zero-one integer programming (ZOIP) method, an important branch of management science, is suitable for dealing with the optimization problem of scheme selection under a limited budget, and has mature applications in the construction field (Juan et al, 2021).…”

The weight score of attributes in the CSC model is based on the rule of equidistant segmentation proposed by Juan et al (2019) and Lu & Juan (2021), where the further the points in the same quadrant are from the center, the greater is their weight value.…”

China is expected to have an annual demand of 1 billion square meters of new residential floor areas in the next few years. Housing developers have adopted various green building technologies (GBTs) in building designs to meet the constantly rising green building (GB) standards. However, they often ignore users’ satisfaction and perception of these GBTs and doubt the cost-benefit assessment of GBTs. This study first constructed GBTs commonly used in residential construction in the Yangtze River Delta region, China. In particular, it adopted the Kano model and the Customer Satisfaction Coefficient (CSC) model to conduct questionnaire surveys on 171 Ningbo households to analyze the differences between developers’ and users’ perceptions of GBTs. Further, a zero-one integer programming (ZOIP) approach was used to build an optimal decision-making model for housing developers to select GBTs that take into account developers’ incremental cost and benefit assessment. The results showed that residents focus on technologies related to comfort and health issues, followed by energy-efficient technologies with lower costs. High-cost and low-scoring GBTs, such as new air systems and Low-E center louvered glass, will be excluded. The decision model clarifies the differences between developers’ and users’ perceptions of GBTs and effectively assists developers in rationalizing the selection of GBTs. Furthermore, it is suggested that the proposed model can be widely applied to other projects in different regions in the future to promote GB markets in China.

“…The result revealed that the proposed approach could be a useful tool to explore similarities and discrepancies of strategy preferences between designers and users, and these findings could effectively decrease the communication gap for future building design. Juan et al (42) further applied the Kano model and the quality function deployment (QFD) method to identify design strategies for public housing projects. The result indicated that the systematic methods can uncover design and planning strategies for public housing, serving as a guide and reference for future designing.…”

Objective: The sudden outbreak of COVID-19 has greatly endangered public health and life safety, leading to new changes in people's housing needs. The purpose of this study is to establish design strategies that are suitable for China's Multi-Unit Residential Buildings (MURBs) in the post-pandemic era, and to identify the users' preferences for these strategies.Methods: This study compiles a set of design requirements by means of a literature review and expert interviews. Three hundred ninety-five online and on-site questionnaires, based on the refined Kano model, were distributed to respondents to reveal their preferences for these strategies. The relationship between the different demographic variables, the preferences of design strategies, as well as the housing unit preferences of home-buyers were also verified by means of an actual project.Results: This study summarizes the four dimensions and 26 design strategies of MURBs in China during the post-pandemic era. These strategies are further extracted into 6 highly attractive, 5 high-value-added and 4 critical quality attributes. In terms of demographic variables, males need more social space, and the elderly need less office space and separate bathrooms in the master bedroom. Due to the impact of the epidemic, people with higher education levels are more required to work at home, and the overall demand for a home working environment is also higher.Conclusion: The home-buyers' preference survey reveals that the housing unit designed based on the refined Kano model is more attractive to home-buyers. The proposed approach can help to provide important and customized decisions to design firms, housing developers, and the government for MURBs planning and strategy formulation in the post-pandemic era in China. More in-depth user surveys in other regions and investigations into the cost assessment of these strategies might be further conducted in the future.

“…QFD is a method that enables the determination of customers' requests and needs, and includes the planning and development of structured products from design to marketing to meet these requirements [10,30]. This association between customer expectations (the "whats") and technical specifications (the "hows") enables the development of a quantitative criterion that shows the effects of each feature on customer expectations [26,31,32]. The most important advantage of QFD is the digitisation of subjective expert opinions, thus facilitating the determination of preferences [32].…”

“…The book discusses some features that can be integrated into the traditional QFD method to improve efficiency. Juan et al [26] stated that user expectations are different in the production of housing in the building industry. They used the QFD method to reveal the expectations and cognitive differences of the designers and residential users, and to produce solutions.…”

The aim of this investigation was to help select design criteria that highlight customer satisfaction, and thus improve the design quality in buildings, specifically in a building of a thermal hotel. The methodology is based on applying the Quality Function Deployment (QFD) technique to listen to the voice of the customer, in addition to the Analytic Hierarchy Process (AHP), which allows selection of the best design alternative. The literature shows that QFD–AHP methods have been tried in different areas of the building industry, but there are few examples of combining building design processes. In the study process, collaboration environments between stakeholders were established and the operability of the method used was tested with real actors. The matrix solutions realised in the horizontal and vertical sections of the framework of the model can be reused in different projects with different user demands. This added a modular and developable feature to the model. This study revealed that the most important customer needs, in order of importance, are “health”, “service”, “comfort”, and “functionality”. These are followed by “accessibility”, “aesthetics”, and “energy conservation”. According to the findings, QFD was shown to be an appropriate method for transferring customer (occupant) requirements to designs in the most accurate manner, given the complex structure of thermal hotel buildings.
