By law, Berlin's operator of public buildings is required to report energy consumption data for each individual building. The initiative EnergieCheckpoint visualises the data and seeks to make it actionable.

Houses constructed using a simple-build approach leverage high-tech processes for low-tech solutions, as well as smart structural design, to achieve maximum energy efficiency.

Data centres consume huge amounts of energy – and generate plenty of heat in the process. In Sweden, thousands of households are already heated with server heat. Could this be a potential source of clean energy?

To remedy urban issues data is needed. UrbanTide hopes to provide this to local councils and organisations in an easy to use AI package.

Whether you’re more concerned about extreme weather or, correspondingly, an extremely large energy bill, energy efficiency can help resolve both issues.
