SUSTAINABLE RETROFITTING OF EXISTING RESIDENTIAL BUILDINGS: A CASE STUDY USING A RAINSCREEN CLADDING SYSTEM

PhD Arch. Marco Bruno, Prof. Dr. Ing. Daniel Grecea

Abstract

The energetic requalification of the existing buildings stock is a key question in the attainment of the ambitious program regarding the energy efficiency proposed by European Union. There are several measures taken to increase the energy efficiency, both for new buildings and for existing buildings, such us the 20 пїЅ 20 пїЅ 20 EU Policy and the Nearly Zero Energy Buildings goal set by the Energy Performance of Buildings Directive 2010/31/EC, which gives the guidelines to be followed in order to attenuate the energy consumption in this sector. However, to achieve these goals, especially considering the current stock of buildings, new redevelopment solutions are needed, which must be well adapted to the specific needs. The Europe has a vast heritage of buildings built in precast reinforced concrete panels, realized after the Second World War, in order to solve in the fastest way the housing deficiency, especially in Eastern Europe. This article takes in analysis the buildings stock of the post-war dwellings in the city of Timisoara. The study falls to a particular building model and propose a rehabilitation of building envelope, through a particular structure of rainscreen cladding system made of prefabricated modules; this solution allows to adapt the new Europeans guidelines regarding on the energy performance, but also an improvement and increases of the socio-economic value.
