Project description

Improving buildings’ overall energy efficiency

Deep retrofitting is widely considered the most complete and effective approach to upgrading a building. A deep retrofit ensures a building operates in the most efficient way possible, using the least amount of energy. The EU-funded AEGIR project intends to demonstrate a renovation solution to increase the take-up of deep retrofitting that achieves nearly zero-energy buildings. To do so, it will use scalable, high-yielding, non-intrusive, multifunctional plug-and-play envelope solutions, a digital ecosystem of services, and a socio-economic model. They will be deployed in single- and multi-family buildings, educational buildings and offices in Denmark, Spain, France, and Romania.


AEGIR’s main objective is to demonstrate a scalable, industrialised, smart, non-intrusive, quick, and affordable four-packaged renovation solution to boost the take up of deep retrofitting achieving nearly zerAEGIR main objective is to demonstrate a physical and digital sustainable framework that boosts the take up of deep retrofitting achieving nearly zero energy buildings. This approach is supported by (i) innovative, industrialized, high performance and non-intrusive multifunctional plug-and-play envelope solutions to increase the use of locally deployed renewable technologies. These solutions can also be modulated depending on the requirements of the target buildings. (ii) A digital ecosystem of services to improve the whole construction workflow (from design, manufacturing, construction, and operation) reducing costs with a sustainable approach. And (iii) a socio-economic model providing financial schemes and business models at building scale. To demonstrate these objectives the project will deploy all these solutions in four demos (Spain, France, Denmark, and Romania) mixing the retrofitting actions which will use the solutions in four different climates. The demos combine different building typologies (multi-family buildings, educational buildings, offices, and single-family buildings) to proof the concept in buildings and tenants with different requirements. One of the demos (Denmark) is social housing so the intention of the project is to demonstrate that these solutions are feasible for the more demanding public. A second demo is a public school to demonstrate the improved air quality and comfort provided by the solution to solve many of the air quality/ventilation problems in this type of buildings. The project involves all the actors from the construction and energy management value chain with local and international SMEs, large companies, public authorities. Local and international clusters are also included to verify the developments at European level.
