Abstract

The construction industry plays a significant role in promoting economic development; however, it causes several environmental problems. Balancing economic and environmental sustainability (EES) is a key challenge for contractors. Obtaining a sustainable construction program necessitates a significant amount of time, manpower, and expertise in practice. This study develops a method to optimize the construction program with the goal of EES, which deploys the non-dominated sorting genetic algorithm III to rapidly solve this multi-objective optimization problem through Pareto front approximation. Variables and search spaces are defined, and two databases are established for global search. A fast and automated tool is developed based on the proposed optimization method, featuring a convenient workflow and user-friendly graphic user interfaces to lower the entry barrier. The effectiveness, applicability, and robustness of the developed method were validated through four diverse case studies, demonstrating its capacity to achieve carbon reductions of up to 49.02 % and cost savings of 34.54 %. This research helps contractors make informed decisions about the design of optimal construction programs and the sustainability challenges in construction. In addition, it contributes to the intelligent development of the construction industry.

优化施工方案，实现经济和环境的可持续发展

建筑业在促进经济发展方面发挥着重要作用，但同时也带来了一些环境问题。平衡经济与环境的可持续发展（EES）是承包商面临的一项重要挑战。在实践中，获得可持续的施工方案需要大量的时间、人力和专业知识。本研究开发了一种以 EES 为目标优化施工方案的方法，该方法采用非支配排序遗传算法 III，通过帕累托前沿逼近快速解决这一多目标优化问题。定义了变量和搜索空间，并为全局搜索建立了两个数据库。基于所提出的优化方法，开发了一种快速的自动化工具，其特点是便捷的工作流程和友好的图形用户界面，降低了入门门槛。通过四个不同的案例研究，验证了所开发方法的有效性、适用性和稳健性，证明其有能力实现高达 49.02% 的碳减排和 34.54% 的成本节约。这项研究有助于承包商在设计最佳施工方案和应对施工中的可持续发展挑战方面做出明智决策。此外，它还有助于建筑行业的智能化发展。

期刊介绍： The mission of Renewable and Sustainable Energy Reviews is to disseminate the most compelling and pertinent critical insights in renewable and sustainable energy, fostering collaboration among the research community, private sector, and policy and decision makers. The journal aims to exchange challenges, solutions, innovative concepts, and technologies, contributing to sustainable development, the transition to a low-carbon future, and the attainment of emissions targets outlined by the United Nations Framework Convention on Climate Change. Renewable and Sustainable Energy Reviews publishes a diverse range of content, including review papers, original research, case studies, and analyses of new technologies, all featuring a substantial review component such as critique, comparison, or analysis. Introducing a distinctive paper type, Expert Insights, the journal presents commissioned mini-reviews authored by field leaders, addressing topics of significant interest. Case studies undergo consideration only if they showcase the work's applicability to other regions or contribute valuable insights to the broader field of renewable and sustainable energy. Notably, a bibliographic or literature review lacking critical analysis is deemed unsuitable for publication.
