Deterministic Models

Abstract

This chapter presents the formulation and application of deterministic models for service life prediction of buildings and their components. These models are based on regression analysis, either simple or multiple, linear or non linear. Deterministic models are mathematical and/or statistical formulations that allow describing the relationship between the degradation factors and the façade’s condition. All regression techniques are based on the same assumptions, i.e. all methods intend to obtain the function that best fits a set of random data. Simple regression analysis allows obtaining the estimated service life of the façade claddings based on the evolution of the degradation of the overall sample over time. Multiple regression analysis (linear or nonlinear) allows estimating the estimated service life of façade claddings using an equation that includes all the variables that influence their degradation process.
