The purpose of this paper is to provide building owners and design professionals the necessary information to comprehend and estimate life cycle costs of wall assemblies that incorporate Exterior Insulation and Finish Systems (EIFS). Specific examples will be provided to compare these costs to those of exterior wall assemblies that utilize alternative cladding materials. Life cycle costs, in a general sense, can be used by owners and design professionals to evaluate total installation and operating costs of functionally similar exterior wall assemblies over a specific time frame. The scope of the paper will incorporate considerations such as comparative installation costs of EIFS versus other claddings, in addition to the costs of maintenance at suggested intervals. Since economics often plays a major role in the selection of a product or system, this study will provide comprehensive information to assist with the comparison of different exterior wall cladding systems and conditions. Using a life cycle cost method to compare the assemblies is of particular importance since it considers all the relevant costs (present and future) and projects the total operating cost associated with the system.
