Abstract

Construction equipment are main distributors for energy consumption in construction projects. If the construction sector reduces the amount of diesel fuel consumption by 10%, the energy saving attributed to entire industry sources would be approximately 5%. The equipment-intensive operation is tightly involved in energy-intensive operation. Energy considerative operation is a major issues in equipment-intensive operations (e.g., earthmoving or paving operations). Accordingly, the identification of optimal equipment fleet is important measure to achieve low-energy consumption in those operations. This paper presents a system which finds an optimal equipment fleet by computing the low-energy performance of earthmoving operations. It allows creating construction operation model and comparing numerous scenarios using alternative equipment allocation plans. It implements sensitivity analysis that facilitates to find the most low-energy consumption equipment fleet by enumerating all cases exhaustively. A case study is presented to demonstrate the system and to verify the validity of it.
