Enhanced estimation of air emissions from construction operations based on discrete-event simulation

Identifying the environmental impact of construction operations would be the first step to implement environmentally sustainable construction operations. To this end, it is essential to reliably estimate the emissions from construction equipment, which account for the largest share for the total impacts of construction operations. This paper presents a methodology to integrate discrete-event simulation into the emission estimation model in order to enhance the credibility of the emission estimation. This paper also demonstrates the methodology by presenting a case study which analyzes air emission from actual earthmoving operations, and examines the deviation with the estimates from the existing method.
