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.Item Life cycle environmental and cost evaluation of heating and hot water supply in social housing nZEBs(2019-09-05) Hernandez, P; Hernandez, J; Urra, I; Grisaleña, D; PLANIFICACIÓN ENERGÉTICA; SISTEMAS TÉRMICOS EFICIENTESThis paper presents a comparative analysis of different space heating and hot water systems for a social housing project in Santurtzi, Spain. The building, comprising 32 apartment units and currently under construction, has been designed to minimize thermal energy demand, while ensuring comfort and quality of the internal environment for the social housing occupiers. The selection of the heating and hot water energy systems has been carried considering a life cycle perspective both for environmental and economic impacts. Different alternatives have been analysed which compare conventional gas boiler installation, which has been the norm for this type of social housing for the last decades, with various options based on heat pump technology. Life cycle analysis of the environmental effects of electrification of the thermal energy demand through heat pumps show a potential for reducing life cycle CO2 emissions. The economic evaluation done through life cycle costing, comparing investment, maintenance, replacement and operational costs of gas boiler with aerothermal and geothermal heat pump solutions, have shown however that gas heating solutions are still the most competitive economically. Increasing the overall efficiency of those heating and hot water systems that include heat pump technology, while reducing their uncertainty in operation is a key element to ensure competitiveness of heat pumps in the current market.
