Offering access to new smaller zero energy/low carbon homes with the Housing 4.0 Project

Read more about the Housing 4.0 Interreg Project, aiming at a reduction of 25% for production costs of new housing units.

This project, funded under Interreg NWE aims at the development of an affordable Zero energy/low carbon homes (ZEH) by adapting and applying new digital technologies, thus stimulating both consumer and supplier interest.

What is the issue?

NWE (North-West Europe) lacks affordable new low energy housing solutions for 1&2 person households. Existing techniques & practices neglect financial capacities & limited space requirements of this growing group. Thus, occupants often live in too large, expensive & not energy efficient housing units. Indeed, the implementation of the project aims at the reduction of energy use and CO2 emission thanks to an enlarged access to new smaller zero energy/low carbon homes (ZEH), aiming to reduce home building costs by 25% and carbon emissions by 60%. The project also comes in line with the EU 2030 Framework for climate and energy. Targets set up under this instrument aim at cutting 40% of CO2 emissions, increasing the share of renewable energy to greater than 27% and providing at least 27% energy savings across Europe. The North West Europe region is the most industrialised region and the most prolific CO2-emitting region in Europe, for which one third comes from the private housing sector. The lack of great push within the industry to achieve EU targets makes the private housing sector a key element in order to reach those by 2030.

What are the objectives?

  • The facilitation of low carbon technologiesproducts, processes and services uptake in sectors with high energy saving potential, to reduce GHG emissions in NWE
  • Housing 4.0 Energy practices will
    • reduce production costs of new housing units by 25%
    • reduce CO2/m² by 60% emissions for embodied CO2
    • Build 56 units which means a saving of 0.86 kt CO2
  • Objectives in 5-years = 1000 Houses
  • Objectives in 10-years = 50000 Houses

How to develop energy efficient homes?

Housing 4.0 Energy will develop an affordable ZEH market by adapting & applying new technologies & creating consumer/supplier interest. It will reduce production costs of new housing units by 25% & CO2 emissions by 60% (compared with average new built houses, lowering both embodied & operational energy). Transnational development & implementation of digitization (4.0) techniques & a digital platform will create fundamental changes in design, manufacture & construction supply chains. Using a client-based approach, all partners will work with social housing companies & end users. 4 pilot sites will allow to develop tests and demonstration, those sites covering varying contexts, from cities in leading low carbon regions to rural areas in less carbon conscientious regions.

3CEA, the 3 counties energy agency located in Ireland, is one of the partners involved in the Project, together with 7 other Partners from 4 different EU countries (Belgium, Germany, The Netherlands, UK). Check out below the Newsletter of the Project, gathering the main initiatives developed in the pilot sites.

The project includes:

  • Tested, demonstrated and monitored combinations of energy solutions, building techniques, low carbon construction material, all standardised for EU use
  • An online platform to facilitate digitization of building, transferability of solutions, distributed manufacturing & the emergence of sustainable supply chains;
  • 58 model housing units in 4 countries (1,374 Kt CO2 savings) with consumer evaluations;
  • novel training programmes for the building sector & recommendations for policy makers.

Each partner established a regional stakeholder group, including housing companies, authorities, architects, engineers and construction companies using & developing the open source 4.0 platform.

The project is funded under the NWE Interreg Program. The total budget for this project amounts to €4.2 million, with €2.5 Million ERDF funding.
