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.

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.
