Item Energy performance assessment of innovative building solutions coming from construction and demolition waste materials(2021-03-05) Cal, Beatriz Fraga De; Garrido-Marijuan, Antonio; Eguiarte, Olaia; Arregi, Beñat; Romero-Amorrortu, Ander; Mezzasalma, Giulia; Ferrarini, Giovanni; Bernardi, Adriana; Tecnalia Research & Innovation; EDIFICACIÓN DE ENERGÍA POSITIVAPrefabricated solutions incorporating thermal insulation are increasingly adopted as an energy conservation measure for building renovation. The InnoWEE European project developed three technologies from Construction and Demolition Waste (CDW) materials through a manufacturing process that supports the circular economy strategy of the European Union. Two of them consisted of geopolymer panels incorporated into an External Thermal Insulation Composite System (ETICS) and a ventilated façade. This study evaluates their thermal performance by means of monitoring data from three pilot case studies in Greece, Italy, and Romania, and calibrated building simulation models enabling the reliable prediction of energy savings in different climates and use scenarios. Results showed a reduction in energy demand for all demo buildings, with annual energy savings up to 25% after placing the novel insulation solutions. However, savings are highly dependent on weather conditions since the panels affect cooling and heating loads differently. Finally, a parametric assessment is performed to assess the impact of insulation thickness through an energy performance prediction and a cash flow analysis.Item Innovative pre-fabricated components including different waste construction materials reducing building energy and minimising environmental impacts (InnoWEE)(2019-08-13) Fodor, Loredana; Ducman, Vilma; Ferrarini, Giovanni; Tamburini, Sergio; Tsoutis, Constantinos; Becherini, Francesca; Garrido-Marijuán, Antonio; Mezzasalma, Giulia; Rossi, Leonardo; Lezak, Emil; Bernardi, Adriana; Tecnalia Research & Innovation; EDIFICACIÓN DE ENERGÍA POSITIVAInnoWEE is a four-year project (from 2016 to 2020) financed by the European Community that involves ten partners from different European countries, as Greece, Italy, Belgium, Romania, Slovenia, Spain and Poland. The aim is to use the waste materials coming from construction and demolition processes of buildings and include them into a geopolymeric matrix with the purpose of producing prefabricated panels for different applications. Construction and demolition waste (CDW) materials with suitable characteristics have been selected to develop high performance geopolymeric panels for building walls envelopes and radiant panels for indoor walls and ceilings with low environmental impact. Field tests will be carried out in different sites in Europe characterized by different climatic conditions to check the simplicity of the installation procedure and the performance of the panels in terms of energy efficiency and environmental impact.
