Utrecht, The Netherlands
Social renovation of residential blocks by industrialization
The Dutch demo case consists of two clusters of social housing buildings in the districts Overvecht-Noord and Kanaleneiland-Zuid, located in the city of Utrecht.

Both districts were built in the 1960s and 1970s to account for the quick rise in urban population and are in general of low-quality. Both districts share the characteristics of lively multi-cultural districts, with a high share of social housing, schools and shops. The residential areas are densely populated districts, home to a majority of low-income households. Both districts have a triple energy infrastructure: a district heating network, gas infrastructure for home-boilers and an electricity grid.

The demonstration actions that will be undertaken by the ARV project are the resource efficient, systematic retrofitting of 8 residential apartment buildings from the 1960s into Positive Energy Buildings embedded in a green neighbourhood, with a global area of 63 600 m²​.

Technologies and innovations
  • Industrial prefabricated modular component integrating construction, energy and climate installations
    • Facades flat: integrates heat recovery for LT heating and ventilation, DC-ready cabling and (BA/BI), PVpanels, insulation, air-tightness.
    • Facades end-façade: mounting PV, configuration/standardisation, insulation, air-tightness, other add-ons.
    • Roof system: Heat Pump, insulation, air-tightness, warm water, PV, integrated piping and ducts.
  • Design and implement Inside Out 2.0​
    • Deep insulation​, decentralised HVAC​, aluminium window frames and triple glazing​, screens to prevent overheating in summer​, on-site assemblage to minimise time and nuisance
  • Smart building control optimization
    • Monitoring of performance, energy usage, comfort levels
  • Social renovation
    • Before the actual renovation the housing corporation will engage with tenants to explore social challenges and opportunities of the tenants, and support tenants in dealing with these social topics. ​
    • The key innovation of ARV includes also the post-renovation coaching to improve tenant’s long-term resilience for social challenges and opportunities.
