A Value-Based Decision-Making Model for Selecting Sustainable Materials for Buildings

Abstract

Nowadays, the earth faces problems and challenges from different circumstances due to the dramatic rise of urban modernization. The construction industry is the most contributor to climate change. Achieving sustainability in construction is complicated, but one of the most optimal strategies is selecting building materials with a lower carbon footprint. Therefore, this research aims to investigate the criteria for sustainable materials selection, rank and prioritize sustainable criteria, and developing value-based decision making. A mixed method was used to satisfy the objectives through an extensive literature review, surveys, and interviews with experts. The statistical descriptive was based on a scatter plot of mean and standard deviation, AHP judgment and Value-based decision-making using function over cost. There are two alternatives obtained in this study: Aluminum Composite Panel (ACP) and Stainless Steel. As a result, the suitable alternative for sustainable façade material is ACP based on value-based calculation. The tendency of choosing sustainable material depends on the stakeholders, owner of the building, designers, and others. The research is to show the way in selecting sustainable material by using value-based analysis. This study could expect to give feasibility and useful knowledge in solving problems and increase the use of sustainable materials in building construction. Future research may be conducted with different requirements for sustainable materials. AHP and Value-based analysis are structured technique that solves a complex problem easily using mathematics and psychology approach.

“…The study has a similar result compared to the previous study that discussed the suitable material selection in buildings [48] and improves the site selection process by incorporating GIS AHP and VBD methodologies, with a specific focus on improving cost-related criteria. Decisionmakers can choose the optimum location based on specified criteria and financial considerations gleaned from GIS data much more effectively when GIS, AHP, and VBD are employed.…”

Sustainability Assessment of a Low-Income Building: A BIM-LCSA-FAHP-Based Analysis

“…Mayhoub et al [27] applied AHP in the development of a new evaluation framework based on four green building rating systems for selecting sustainable façade materials. A similar study was conducted by Ruslan et al [33], who used AHP and Value-based Analysis to choose the most sustainable material for façade use, between Aluminum Composite Panel (ACP) and Stainless Steel. Dinh et al [25] identified a list of 18 sustainability criteria applicable to the selection of sustainable materials in Vietnam, and used AHP to rank them based on their degree of relevance to the country's construction sector.…”

“…Despite the relevance of optimizing the construction materials selection process, currently, in practice, this is still primarily done empirically, based on the engineers' knowledge and experience, rather than numerical approaches [30][31][32]. However, when associated with the lack of experience of the responsible professional, this heuristic approach prevents the available alternatives from being objectively compared [25,33], and the lowest price ends up prevailing as the most important choice criterion. Therefore, it is essential to develop a systematic decision model that helps team members to choose the most advantageous materials, based on well-defined, sustainable, and unambiguous criteria [23,32].…”

Public Toilets Design Thinking in the Architecture Design Process

“…Since the 1960s, architecture students introduced this movement to solve problems formulated in project proposals. The architect's job is to be the one who best knows how to solve the problems their partners need [9]- [12]. This method was followed by famous architects [13]- [17].…”
