Proposal of Methodology for Technical Inspection and Rehabilitation Intervention for Multi-family Building of the 60’s in Portugal
The rehabilitation of old buildings has been increasing over the last few years due to the lack of maintenance and there is an advanced degradation of the Portuguese built park. This sector of the civil construction has as objective the full reutilization of the existing buildings maintaining its identity. Since Portugal has a large percentage of buildings where it is possible to identify constructive times that accompanied the implementation of different trends and technological evolutions, defining differentiated strategies for intervention. The 1960s deserve some prominence in Portugal because it is composed of a significant set of buildings with reticulated structure in reinforced concrete and without concerns from the point of view of thermal behaviour, which are now inhabited mainly by elderly people, often residing alone. The following work aims to present a methodology proposal and apply it to a case study. The proposed methodology includes the detailed inspection of a building from the 60s in Covilhã, the consultation of residents and the definition of intervention proposals based on the main nonconformities detected. In the first stage, a detailed analysis of the existing situation is proposed, which includes a technical inspection report on the common parts and the different fractions of the building and a survey of residents in order to know their opinions and expectations regarding the work to be carried out. In the second phase we propose a set of measurements, the realization thermograms and the thermal analysis of the different habitable fractions of the building based on the current thermal regulation. After analysing all the data collected, the intervention proposals are defined according to the needs of the building and the residents, in a phased way and with the aim of creating better accessibility, comfort and use conditions.
