Cuantificación de residuos en obras de rehabilitación energética de edificios = Quantification of waste in building energy rehabilitation works

This article presents the results of the research project "From waste to resources (W2R)" that analyzes the generation of construction and demolition waste (RCD) in rehabilitation works for the improvement of the energy efficiency of buildings and develops new materials, elements and construction systems manufactured from RCD. This article presents some of the results of the W2R project, specifically, the identification, quantification and characterization of the categories of waste generated in rehabilitation works for the improvement of energy efficiency carried out in the vertical envelope of buildings. For this, the most common actions to improve the energy efficiency of the vertical envelopes were identified and the generation of CDR in two works was quantified using experimental methods (in situ data) and theoretical (software). The results showed that the greatest amount of RCD generation occurs during the vertical surface preparation operations prior to developing the performance. In addition, it was found that the most generated waste categories are: concrete, ceramics, metal and wood.
