ECRC was invited to present ReCO2ST at a Cluster International Conference in Bologna organised by the Department of Architecture of the University of Bologna. Purpose of the conference was to bring together and present the state of the art on technological and energy saving innovative solutions for the built environment, produced through H2020 funded projects (TES Energy Façade, MORE-CONNECT, RenoZEB, P2Endure, 4RinEU, TESSe2b, ZERO-PLUS, SMART GEMS, GridAbility), ReCO2ST being one of them. Currently plethora of solutions is being produced, especially with regards to retrofitting the existing building stock. The need to accelerate renovation in Europe was highlighted as well as the need to start involving end-users from an early stage so as to assist awareness spreading and uptake of the proposed solutions.
