A comparative study of applying different economic evaluation techniques to assess the choice of building materials in educational facilities

Abstract EN

Minimizing building construction and operation costs is always a major concern for buildingstakeholders.

Therefore, it is crucial to select an appropriate technique to evaluate theeconomic performance of the building's component.

While economic evaluation techniquesvary, including the Life Cycle Cost (LCC) of the building has proved to be an effectivemeasure in reducing the total cost throughout the building's life.

In this paper, 3 LCCevaluation techniques are utilized in a comparative case study to determine the best exteriorwall assembly choice for a school building.

The case study illustrates that each economicevaluation technique can result in a different favorable choice order, even though all LCCevaluation techniques resulted in the best choice.

Moreover, including the energy andoperation cost can greatly affect the assembly choice.

The more thermal resistance anassembly has, the more LCC savings occur, until a certain resistance value, where it becomesless feasible.
