1 February 2022

Dacia Gymnasium School in Oradea was thermally rehabilitated in a project to increase energy efficiency carried out by Oradea City Hall. The works, worth about 9 million lei, were executed by the association of companies formed by Conpila SRL – leader of the association and Inselma SRL.

The building has become energy efficient, announces Transilvania Business, as the annual primary energy consumption reduced by at least 50% compared to the initial consumption. Greenhouse gas emissions have been reduced to 16 kg/sqm/year.

The works consisted of thermal insulation of the facade, installation of PVC joinery, Low E, equipped with adjustable step closure systems and ventilation grilles. At the same time, the rehabilitation of the power supply and lighting system was carried out by rehabilitating the electrical installations, respectively the replacement of the existing panels with new high-performance and reliable equipment.
