This requires new innovative solutions and services to be rapidly implemented in the market. Research Infrastructures that give support for later-stage developments (high Technology Readiness Levels) can play a relevant role in both the technological development and market introduction of construction products for energy efficient buildings. The following paper describes such an infrastructure (KUBIKby (Tecnalia)) located in Bilbao (Spain) and its major outcomes in the period 2011-2015.6182703enginfo:eu-repo/semantics/openAccessEnergy efficiency achievements in 5 years through experimental research in KUBIKconference output10.1016/j.egypro.2015.11.009Energy efficiencyR&D infrastructureEnergy efficiencyR&D infrastructureGeneral EnergySDG 7 - Affordable and Clean EnergySDG 8 - Decent Work and Economic GrowthProject IDinfo:eu-repo/grantAgreement/EC/FP7/248605/EU/Friendly Intelligent Energy Management System for Existing Residential Buildings/FIEMSERinfo:eu-repo/grantAgreement/EC/FP7/248605/EU/Friendly Intelligent Energy Management System for Existing Residential Buildings/FIEMSERFunding InfoSpanish Ministry of Education and Science, Spanish Ministry of Science and Innovation, European Regional Development Fund, European Union Seventh Framework Program, Basque GovernmentSpanish Ministry of Education and Science, Spanish Ministry of Science and Innovation, European Regional Development Fund, European Union Seventh Framework Program, Basque Governmenthttp://www.scopus.com/inward/record.url?scp=84962530072&partnerID=8YFLogxK
