Technical-economic analysis, according to European methodologies, and software for residential buildings (EPIQR), offices (TOBUS) and hotels (XENIOS). Overall assessment of the current condition and degree of deterioration of the building and its individual elements (shell and installations), taking into account their functional insufficiency due to age. Multi-criteria analysis for the evaluation of energy and natural resource saving potential, taking into account the quality of the indoor environment and environmental impacts.
