The overall objective of the project is to increase the energy efficiency of the Iasi Clinical Recovery Hospital building from energy class D to energy class B, applying the innovative deep renovation concept, which consists in implementing deep energy rehabilitation measures. At present, building C1 of the Iasi Clinical Recovery Hospital does not have the basic quality requirement E – Thermal insulation and energy saving, being in energy class D. The project provides for deep energy rehabilitation measures consisting of enveloping the building, interventions on installations and lifts and the implementation of renewable energy solutions. As a result of these interventions, the building will be in energy class B.
