The aim of the project is to increase the energy efficiency of the 1st and 2nd floors of the A-housing, the B-housing and the 1st and 2nd floors of the C-housing, by reconstructing the technical systems of these housings and the spatial solutions concerning them. Reconstruction works are planned in relation to energy efficiency improvements (including the installation of solar panels), the construction of heat recovery ventilation systems, the replacement of opening fillings and the refurbishment of premises due to service needs.
