Different types of thermal activation of building structuresare increasingly utilized in buildings including BIPV, multifunctional PV facades with controllable daylight/solar gain features and integrating thermal and electrical output. Much of the existing R&D is focused on these facades and structures with the rest of the building, but detailed information is scarce on relevant properties and the performance.This paper presents dynamic analysis and optimization results of PV air-conditioning and PV based sanitary water heating system, which by heat recovery assisted, demonstrates cost effectiveness which significantly surpassesthe corresponding values of direct solar thermal conversion systems. The ?study objective was to propose technical solution for replacing fossil fuel and electricitywith solar energy for air conditioning in addition to water heating for different purposes (pools, sanitary water,washing) in the Special hospital of the Spa Rusanda Melenci. Crucial for the study success was prediction of air-conditioning loads and synergetic relations betweenenergy efficiency, solar radiation intensity stochasticchanges, PV systems electricity production and sanitary water consumption dynamics.
