The Importance of Renovation and Renewable Energies for Carbon Neutral Building

Energy consumption is one of the most crucial factors of sustainability. Our existing building stock is one of the biggest energy consumers in the world and that is why having to focus on the minimization their energy usage. More countries and the E. U. set the goal for carbon neutralization of building sector in the year 2050. The regulations for newly built require them to be buildings can be energy efficient. What should be done with the existing buildings? The paper aims at to look inside the REHOUSE renovation project supported by the European Union. The project offers several innovative renovation packages which can be used during the renovation of old buildings. Some of these packages develop active energy saving proposals such as Multi-sourced heat pumps driven by renewable energy or Smart wall system and Intelligent window. Others offer a passive solution such as the Adaptable dynamic building envelopes and PanoRen facades. All these innovations based on applied science knowledge and use the finite element modelling or other physical science tools. It is expected that the program of energy retrofit renovation will provide more research interest.
