This paper discusses the formula, which can conveniently calculate the Life Cycle Costs (LCC) based on the conditions of the maintenance in office buildings. To decide renewal or reconstruction for aged office buildings, building owners can refer to this formula to compare two options in terms of LCC and choose the one with the lower annual LCC for a renovation of their assets. This formula can calculate running costs within LCC in order to evaluate building maintenance conditions and include renewal costs as one of factors in LCC calculation.
