Renovation of semi-attached homes of housing association using Woonconnect tool

The Use Case aims to involve tenants in the process of renovating and maintaining homes owned by the social housing association Woonbedrijf. It enables tenants to make informed decisions on what pre-defined renovation options they want to realise. The digital 3D-tool WoonConnect allows tenants to see the effects of their behaviour (i.e. showering, heating) and the expected results of the renovation.

Through the web application, the device provides immediate feedback on what the influence of several renovation options will be.That offers a new level of information to the tenant and therefore, empowers them to make reasonable decisions. The development was accompanied by several direct interactions to capture various residents' preferences.

Legal and Political

Due to the binding regulations, the housing association has to maintain and improve the houses in the district. Therefore, there is an agreement to enhance the average social house to an energy label B, owing to the official regulation to have an energy label on each home.

Supporting Infrastructure

The types of houses are fairly similar through the Netherlands: Therefore, the scaling-up opportunities are rather high once the model is built in WoonConnect. 


Generally high usage of new technology / however not in several important tenant groups. 


PRIVACY: Creating enough trust for the data to be collected through the WoonConnect tool. Different partners involved were interested in many different kinds of data, and therefore tenants became afraid of the type of questions asked and the possible uses of the data.


  1. Not all tenants prefer digital interaction (via the tool) or interaction in general. Main influencing factors are age and trust in private and public authorities. It is essential to know your customer: is the digital tool right for the user?
  2. Data privacy in private homes is perceived much more pressing than in other digital areas (such as social media)
  3. The direct and personal interaction at 'kitchen tables' was highly crucial for the success of the project - therefore, the process was redesigned to use WoonConnect NOT as a self-service but as a guided experience
  4. The process of giving tenants the power to chose, brought them closer to the public partners and each other
