Once Romania has joined the European Community, environmental protection and energy saving have become top priority domains. European standards and codes have become Romanian reference standards and norms.
The present-day housing stock in Romania was mostly built between 1960 and 1989, without the adoption of any efficient solutions for thermal insulation. The operation of buildings more than 30 years old, without general repair work, has led to the occurrence of certain damages, because of the condense phenomenon into the walls.
In Romania a governmental programme is carried out for the thermal rehabilitation of blocks of flats built before 1989. The investment for the thermal rehabilitation of buildings is financed equally by the government and the owners. For each building an energetic expertise is to be performed, in order to issue an Energetic Performance Certificate.
This paper presents the situation of the housing stock in Romania, the evolution of codes and requirements regarding the resistance to heat flow for the elements of the building envelope as well as the latest tendencies concerning the erection of durable constructions. In the end, the author presents the thermal insulation solutions adopted for the construction of the “Iulius Mall” Commercial Centre in Timisoara (~80,000m2), the heat loss calculations and the building energetic certificate.
