Flatmettoekomst won the Sustainable Renovation Grand Prize of the 2019 Green Solutions Awards et the Netherlands level + a mention for the international Sustainable Renovation Grand Prize.
Flatmettoekomst is a net zero energy retrofit of apartment buildings dated from the early sixties of last century. The project consist of 48 apartments. Currently an additional 80 apartments are retrofitted with the same concept.
This renovation is a complete refurbishment of the apartments. Main goal was to deliver a nett zero energy building, but als the renewal of kitchen, bathroom and toilets, upgrade of the communal area's in the building were part of the project.
Another unique point of the project is bringing it back to the original architectural design.

If you had to do it again?
What would I do different the next time? Because we worked on this project for several years, step by step we had the opportunity to make it better step by step. These were relative small changes, I described the placing in an more invisible way of the solar panels above.
A question that I asked before we were obliged by the municipality to stick to the original architecture was: can we be more free in the renovation of the façade? We have so many the same buildings of this type in Holland. Can we allow ourselves a renovation with a totally new façade? Hopefully we will get the change someday.

Building users opinion
During the first year of occupation, an independent party followed the residents and measured their satisfaction with their new home. Satisfaction with the climate system was also examined. The residents give an overall rating of 8 out of 10.
- 1,00 kWhpe/m2.year
- 150,00 kWhpe/m2.year
- 225,00 kWhpe/m2.year
Total energy demand is generated by solar pv-panels; total energy consumption equals the total energy output of the panels

Factory Zero delivers a completely integrated system for heating, domestic hot water supply, double flow ventilation and monitoring.
Factory zero delivered a total concept and had experience in other zero energy projects. They were able to make a tailor made solution that fitted exactly on the (former) balcony.
