ZERO-PLUS project settlement in Voreppe, France

Share this Post:

The aim of ZERO-PLUS (Acronym of "Achieving near Zero and Positive Energy Settlements in Europe using Advanced Energy Technology“) research project is to search for buildings design for new highly energy performing buildings. In this project, a comprehensive, cost-effective modular system for Net Zero Energy (NZE) settlements will be developed and implemented in four case studies across the EU: Cyprus, Italy, France and the UK.


The French case study is located in Voreppe, a city of 10,000 inhabitants located 15 km North-West of Grenoble. It is connected by frequent trains (10 minutes) to Grenoble. The location of the case study is immediately next to the train and bus station and connected to all facilities within walking distance. 


The case study consists of the construction of 18 dwellings in a 5 storey-building for social renting (around 1500 m2). It is integrated in a larger program, with a second building with 25 social housings for rent and a third building with 20 dwellings for social selling. Dwellings will be distributed around a central column and all of them will have a living-room with a large balcony facing south-east or south-west. A shared underground parking plot will be created for both social housing buildings.


The case study is built according to the French BEPOS standards (Bâtiment à EnergiePOSitive = POSitiveBuilding), which includes goals on energy consumption as well as on grey energy. It will be connected to the local biomass district heating, but will also produce energy by the installation of ZERO-PLUS technologies on the roof (Windrails® by Anerdgy and HCPV modules by ARCA) or integrated in the façade (glass blocks by SBskin).


It will be built and managed by OPAC38, which will ensure the appropriate commissioning, monitoring and end-users taking-over. 


The design of the French case study fulfils the three performance objectives of the project:


  • reduce the net regulated energy usage to an average of 0-20 kWh/m2 per year (corresponding to 70 kWh/m2 per year of regulated energy);
  • generate at least 50kWh/m2 renewable energy per year, on average;
  • reduce the full cost of NZE settlements by at least 16% compared to current costs.

At later stages of the project, and after realisation of the settlements, the three performance objectives will be revisited again to confirm they are also fulfilled in practice.
