The article discusses the problem of defining borderline values of technical wear of a building and/or its components. Formulas and methods of defining wear have been highlighted, and an example has been presented, where the calculations were made according to proportionality formulas: Ross and Unger, Romstorfen and Eytelwein. While analysing results, some differences have been pointed out in the assessment of the degree of wear, depending on the time lapse and selection of a calculation formula. Selecting an inappropriate calculation procedure (depending on the focus on an element), and incorrect manner of defining technical life span of an element or a whole building leads to serious errors. The justifiability of the above statement has been proved in the summary, where a comparison of element use, according to different calculation formulas, has been presented in a graphic form.
