Description

An evaluation methodology to estimate social housing envelope degradation level was developed which has been applied to a set of social housing. The degradation level of each of the principal anomalies was determined as well as the evaluation index of the building envelope. Degradation evaluation results were obtained through visual survey and were aggregated by a method develop for the research. With the aim of discovering the subjacent mechanism of the visual phenomena, models have been constructed to analyse the behaviour of each dependent variable (anomalies), in function of the independent ones: building age, cover type, last repair action, proximity to sea, trees, main roads, industrial zones and collective buildings. After obtaining the building index evaluation, models were developed that permit the estimation of the influence measure of the predictor variables in this index. The aim of this paper is to present the models for obtaining the envelope index evaluation of a set of dwellings. This has been used in the scope of a research project on prioritising refurbishment interventions in the Portuguese social housing stock (Rodrigues, 2008).
