The general objective of the project is to increase the energy efficiency of the Iasi Recovery Clinical Hospital from energy class D to energy class B, applying the innovative deep renovation concept, which consists of implementing deep energy rehabilitation measures. Currently the C1 building of the Iasi Recovery Clinical Hospital does not have the basic E-quality requirement – Thermal insulation and energy saving, falling within energy class D. The project provides deep energy rehabilitation measures consisting of the envelope of the building, interventions on installations and elevators and the implementation of renewable energy solutions. As a result of these interventions, the building will be classified in energy class B.
