  2. Green Deal Europe Clean, Reliable and Affordable energy Achieving Climate Neutrality Take everyone along (Just Transition Mechanism) Sustainable transport Farm to Fork Preserving Europe’s natural capital A Zero pollution Europe Transition to a Circular Economy Financing the transition Towards a Green CAP
  3. Green Deal Europe Achieving Climate Neutrality • 2030 – 55% CO2 reduction • 2050 – CO2 neutral Buildings responsible:  40% energy consumption 36% greenhouse gas emissions
  4. Green Deal Europe Achieving Climate Neutrality – Renovation wave • 2030 – 35 million buildings renovated • 2050 – 152 million buildings renovated Need for an industrial approach at lower costs!
  5. The project
  6. Background • Interreg NSR • 4,4 Mln • July 2018 - December 2021 • 14 project organisations • 6 countries (NL, D, BE, S, N, UK) • 6 members advisory board
  7. Partners and advisoryboard members
  8. INDU-ZERO in a nutshell • Blueprint for a high-tech building factory • 50% of the current price for a Net Zero renovation • 15.000 renovation packages/year per factory • Employment for about 260 people/factory and 300 people on building sites
  9. Clients & Housing stock
  10. Housing associations and real estate owners
  11. AppartmentSemi-detachedTerraced 3 archetypes
  12. Renovation packages
  13. Note: U-value is equal (0,24W/m²K)  No differences due the environmental impact of the energy use Life cycle analysis Selection of renovation system Glass fibre polyester Glue Oriented strand board (OSB) Glue Expended polystyrene (EPS) Glue Glass fibre polyester Base plaster Glass fibre reinforcement Cover plaster Glue Stone wool Oriented strand board (OSB) Timber frame + stone wool Fibre board Cavity structure Fibre board Base plaster Glass fibre reinforcement Cover plaster Sandwich panel Timber frame panel
  14. LCA -Selection of renovation system Comparison between the environmental impact: – Slight preference for sandwich panel
  15. • Sandwich panel is favoured over timber frame panels – The difference in environmental impact between both is small and strongly depends on the materials that are used • OSB, glass fibre polyester and EPS are the main contributors in the environmental impact of the sandwich panel LCA study - Conclusions
  16. Development of the renovation packages Facade (sandwich panel with EPS) Roof (sandwich panel) Including: • Ventilation & • Heating systems

  5. Different possible packages – where to focus? Timberframe o sandwichpanel - LCA
  6. Firesafety class B
  7. 15.000 renovation packages a year
  8. Large amount of current costs lie here
  9. Workforce of 5 persons per house
  10. Strategy for their housing stock until 2050 Changes of national, regional and local legislation to enable mass renovations of the building stock
  11. Changes of national, regional and local legislation to enable mass renovations of the building stock
  12. Trias energetica concept: 1) Reduce the demand for energy 2) use sustainable sorces 3) use fossil energy as efficiently as possible
