During the course of the ECODISTR-ICT project, a series of workshops will be organised to gather stakeholders, discuss their views and define ambitions for the Rubroek neighbourhood in Rotterdam, the Netherlands. You can read up on the outcomes of the first two sessions here.
The third session was held on 3rd May 2015, in Rotterdam. During this session the participants focussed on decisions for the energy infrastructure of the Rubroek neighbourhood. Given that the natural gas network infrastructure has reached the end of its life cycle, the key stakeholders in the district have the opportunity to either replace the existing system or opt for another energy carrier.
Three alternatives have been discussed:
- Replacing gas with gas (business as usual):
In this alternative, the grid operator removes the old gas grid and puts in a new gas grid. The housing corporation will continue with placing high efficiency boilers and large maintenance as planned. With this solution, the high efficiency boilers will only provide a small energy bill benefit for the residents. Since the street will be opened up, this presents an opportunity to rethink the image of the public space.
- Replacing gas with district heating:
In this alternative, the grid operator removes the old gas grid and the district heating company puts in a district heating grid. The housing corporation should engage the tenants to the point that 70% of them agree with this change and individual high efficiency boilers will be removed.
- Making smart combinations based on the geography of the area:
In this alternative, the following constraints are taken into account: some buildings are conveniently located for district heating specificities, while in other cases it proves very difficult to make that switch, or even be a showcase for all-electric. So, next to the district heating alternative, for the all-electric buildings, the grid operator removes the old gas grid and the housing corporation renovates the houses to the extent that they are nearly zero energy buildings (very low heating demand with better insulation, and production from heat pumps and photovoltaic cells).
These decisions will be investigated further by the ECODISTR-ICT team in close cooperation with the stakeholders, leading to a final workshop session. This session is planned for the end of June, when the demo of the IDSS should provide the key stakeholders with data evidence to support their decisions.
