This work presents a methodology for obtaining a quantitative expression of the superficial
deterioration of bricks affected by climatic conditions. The method combines in situ measurements
with laboratory data. Input data on material recession were obtained from photogrammetric observations,
the material properties were derived from laboratory tests or the relevant literature, and
climate data were provided from regional environmental monitoring service. The climatic parameters
considered in this study are: relative humidity, number of freeze-thaw cycles (i.e., mean number
of days per year with temperatures below zero), and peak sun hours per day. The methodology
proposed estimates the deterioration rate of brick façades under variable climate conditions over time.
As a conclusion of this research, a new tool for the structural evaluation of brick walls is presented.
