The Development of a Decision-Support System (DSS) for Selecting Best-Fit Zero-Carbon Building Materials; The Cases of Iran and New Zealand Building Industries

Abstract

A zero-carbon building is a green and environmental-friendly structure designed and functioning with the primary objective of eliminating or reducing carbon dioxide, thereby positively impacting natural resources and climate change. The current worldwide focus on sustainability and decreasing carbon emissions has significant consequences for the construction sector. The purpose of this qualitative study is to determine the factors that influence the decision making involved in material choice for zero-carbon buildings by senior construction professionals. In addition, this study seeks to provide mechanisms to overcome the barriers for stakeholders to meet the sustainability challenges in the industry. The research investigates decision-making changes between conventional and sustainable construction and provides a pathway for zero-carbon construction. It will be essential to develop insights into responsible sourcing as an area of growing industry relevance and compare the influence of these factors between New Zealand and Iran. Comparing these two countries with quite different building materials and construction practices could show some interesting emergent properties that both countries could benefit from. The culture of using these materials and the reasons behind their use can advance the body of knowledge in the construction sector. The scope of this proposal is sufficiently well-defined to make the project feasible in the time allocated. The findings of this study will be beneficial to society, considering that zero-carbon buildings play an important role in the move to a more sustainable future. The greater demand for greenhouses for individuals and companies justifies more effective constructional approaches. Thus, government, businesses, and individuals that apply the recommended approach derived from the results of this study will be able to sustain the environment better. The New Zealand and Iranian construction industry stakeholders, will be guided on what materials should be used to improve resources efficiency. For researchers, the study provides insight into critical areas that have received limited attention in zero-carbon construction and renewable construction materials.
