Discover Mustbe0 in Germany
To reach climate targets, the building stock in Germany needs to be CO2 neutral by 2050. This poses two key challenges for politics, housing and construction companies: firstly, the number of highly energy-efficient refurbishments must increase significantly. At the same time, homes must remain affordable.
Energiesprong - a revolutionary, whole house refurbishment standard and funding approach initiated in the Netherlands – is a solution for the above challenge and has already proved itself in the Netherlands, France and the UK mainly for single family housing stock. With industrialised processes and new technologies – such as prefabricated facades, insulated rooftops with solar panels, and smart heating installations – residential buildings can be brought to a future-proof zero-energy standard in very little time and at affordable costs.
As with many other European countries, a large number of people in Germany live in apartment buildings. To develop the right solution for this building type, Mustbe0 in Germany, coordinated by the German Energy-Agency (dena), will focus on apartment buildings from the 50’s to the 70’s. This relatively large stock of similar buildings belong to only a few housing associations. This makes it easier to aggregate demand, so the supply side can start to invest in innovative processes and products.
It is foreseen that the solutions developed within the Mustbe0 project can also be transferred to other types of buildings such as larger multi-family houses, single-family homes and non-residential buildings.
Prototypes and scale
In 2019/2020, the first prototypes will start. Nationwide, frontrunners from the housing sectors have identified buildings that will show how the Energiesprong approach works. This will kick start the market. Those frontrunners are:
- Arsago ACM with a prototype in Hameln
- Baugenossenschaft Oberricklingen with a prototype in Hannover
- VBW Bauen und Wohnen with a prototype in Bochum
- Vonovia with a prototype in Bochum
- Wohnungsgenossenschaft am Vorgebirgspark with a prototype in Cologne.
These first pilots are critical to starting the market development. They are supported by the EU Interreg NWE Mustbe0 programme and the BMWi.
The prototypes will be closely monitored and communicated to the German market as well as to the other European market development teams. This will help share knowledge and optimise perception among politicians, stakeholders and society. Additionally, this will motivate and enable more companies and stakeholders to join the movement. It will lead up to a larger scale of aggregated demand, preparing a broader market for net zero renovations for apartment buildings in Germany.
