The objective of this research is to develop a methodology for planning and designing environmentally conscious construction by addressing the interdependency of time, cost and environmental impact (TCEI). The importance of the construction industry in terms of its environmental impact is very well recognized and reflected by the large amount of energy use in existing buildings and construction processes. Nevertheless, the environmental impact of construction processes is still poorly understood. Construction projects are typically executed under multiple constraints such as project schedule, budget, quality and safety. Future advancement of environmentally conscious construction hinges on a better understanding of the interdependency of TCEI. To achieve the objective, a simulation environment called Simulation of Environmental Impacts of Construction (SimulEICon) will be developed to quantitatively and accurately ?reveal? the interdependency of TCEI. The researchers will work with facility owners, designers, contractors and subcontractors to collect sample projects, best practices of environmental impact mitigation measures, and other data related to environmental impact analysis. Hypotheses will be tested using SimulEICon and collected data. The findings of this research are critical for many aspects of construction, for example the selection of optimal construction methods under multiple constraints, e.g., time, cost and environmental impact, the development of new contracting practices that address more stringent environmental requirements, the integration of environmental impact mitigation and project management, and construction education. Since sustainability is a critical education component for many science technology engineering and mathematics (STEM) disciplines, the findings from this project will provide useful data for a wide range of subjects in the construction engineering and management discipline. SimulEICON will also be a valuable teaching and learning tool. Finally, Florida International University has a proven history of providing STEM education to underrepresented groups. This research will be carefully planned to recruit and retain the brightest women and minority students, so that the project will impact diverse student populations and serve as a cradle for a diverse, high quality construction workforce in the future.

本研究的目的是通过解决时间、成本和环境影响 (TCEI) 的相互依赖性，开发一种规划和设计环保建筑的方法。建筑业在环境影响方面的重要性得到了充分认识，并反映在现有建筑物和施工过程中大量使用能源。然而，人们对施工过程对环境的影响仍然知之甚少。建设项目通常在项目进度、预算、质量和安全等多重约束下执行。环保建筑的未来进步取决于对 TCEI 相互依赖性的更好理解。为了实现这一目标，将开发一个名为“施工环境影响模拟”（SimulEICon）的模拟环境，以定量、准确地“揭示”。 TCEI 的相互依赖性。研究人员将与设施业主、设计师、承包商和分包商合作，收集样本项目、环境影响缓解措施的最佳实践以及与环境影响分析相关的其他数据。将使用 SimulEICon 和收集的数据来测试假设。这项研究的结果对于施工的许多方面都至关重要，例如在时间、成本和环境影响等多重约束下选择最佳施工方法，开发满足更严格环境要求的新承包实践，环境影响缓解和项目管理的整合以及施工教育。 由于可持续性是许多科学技术工程和数学 (STEM) 学科的重要教育组成部分，因此该项目的研究结果将为建筑工程和管理学科的广泛学科提供有用的数据。 SimulEICON 也将成为一个有价值的教学工具。最后，佛罗里达国际大学在向弱势群体提供 STEM 教育方面有着悠久的历史。这项研究将经过精心策划，以招募和留住最聪明的女性和少数族裔学生，使该项目能够影响多元化的学生群体，并成为未来多元化、高素质建筑劳动力的摇篮。
