Decision Making Toward Sustainable Material during Planning Stage at Construction in Seberang Perai Tengah Pulau Pinang

Abstract

The efficiency of using sustainable materials has been an important issue in ensuring the success of sustainable construction in Pulau Pinang. Unfortunately, the construction sector is one of the most energy-intensive sectors, contributing to global climate change and environmental issues. Thus, this study aims to identify the factor of sustainable materials selection in focusing on Seberang Perai Tengah and to determine the relationship between the decision-making factor and elements in the planning stage toward sustainable construction. The quantitative method was conducted by survey, and the instrument used was an online questionnaire survey. About 54 samples of the questionnaire were collected from those involved in the construction sector in Seberang Perai Tengah, Pulau Pinang. The result shows the factors of decision-making that have the most influence on sustainable material selection are technology and training. Meanwhile, the planning stage element that has the most significant influence on the criteria of sustainable material is the project life cycle. This study could be valuable for all parties in the construction industry, especially to the decision-maker, engineers, clients, employers and staff, academicians, policymakers, researchers, and organizations.
