Assessing the Environmental Impact of the Construction Phase – a Simulation-based Methodology.

Abstract: The construction industry makes a significant contribution to global resource and energy consumption and the associated CO2 emissions. The environmental impacts in the execution phase compared to the planning and operating phase have not yet been comprehensively investigated in research for several reasons. This paper presents a methodology for the preliminary calculation of greenhouse gas emissions on the construction site by simulating the nonlinear behavior of the complex and dynamic construction processes. The estimated results will help to optimize the execution planning of theconstruction processes from an environmental perspective.
