In assessing the life-cycle cost of a building, the operation energy and construction energy are considered. The operation energy constitutes 90 to 95 percent of the lifetime energy use of a building. Concern over reducing operation energy has led to advancements where many buildings can now be considered net zero. While considerable advancements were made in achieving net zero in the operation, construction energy use has largely remained the same. To achieve net zero for the entire life-cycle of the building, construction energy consumption needs to be reduced. Excavators are one of the most popular pieces of construction equipment. They are primarily run off diesel fuel which is a nonrenewable resource. Biodiesel is currently offered on the market in different blends. These blends combine alcohol with vegetable or animal oils to create a renewable fuel source. This report will examine if biodiesel can be a viable replacement to traditional diesel used in excavators, and ultimately reduce construction energy.
