Europe’s objective is to achieve climate neutrality by 2050, an economy with net-zero greenhouse gas emissions, through the deep decarbonisation of all sectors.

More than 220 million building units were built before 2001 (85% of building stock) with low or no energy standard criteria and most of them will still be standing in 2050.

The oldest, non-renovated buildings are usually less energy efficient, and require more energy to keep indoor environmental conditions.  In addition, they are often occupied by lower income families which face problems to pay energy bills, which means that the indoor hygro-thermal conditions are far from the comfort range, leading to health problems. 

Work Description

The building envelopes combine a package of solutions including:

  • Improved ventilation: air ducts connected to a central heat-pump and smart windows
  • insulation: biobased thermal insulation and acoustic insulation
  • Bio-composite/bio-resources profile systems and cladding
  • renewable energy generation: flexible PV system and PVT panels
  • electric storage technologies: second life batteries


This solution will achieve a low-energy manufacturing process with a low carbon footprint. It will use different digital technologies (BIM, augmented reality, digital twins, etc.) to improve building design, refurbishing, management, and operation.


Sustainable behavior of buildings

Using industrialized and modular systems, digital tools to follow and control the process and new materials, renewable technologies, and systems

Renovation Design

Enhanced data collection and use in design, planning and implementation

Affordable built environment

Efficient design and renovation process accounting for the needs and necessary conditions of the location and the inhabitants, driving down the costs.

Operational behavior during lifetime

Smart management of energy generated at dwelling and building level through digital twins.

Technical Objectives

Design multifunctional (passive & active) scalable building energy renovation envelope packages to answer to a different range of needs, which integrates:

  • plug & play industrialized highly insulating envelope modules with very low embodied energy
  • built-in renewable energy generation systems, which will be designed, prototyped and tested
  • highly efficient ventilation systems, designed to ensure user comfort and indoor air quality


Develop and implement an ecosystem of digital services in a common data environment that enable

  • an efficient design of the AEGIR renovation packages for different building typologies
  • an efficient building renovation execution and building operation and maintenance


Demonstrate AEGIR technical solution through its implementation and monitoring in four different building typologies (residential, office and educational) located in different climatic zones
