The question is: What are we building instead?
The world is overheating – and our buildings are fueling the fire.
Buildings account for over 30 % of global energy-related emissions – and still rely on outdated systems.
Without bold action, it risks becoming the biggest obstacle to climate progress.
We’re moving too slow – and time is running out!
Only 1% of buildings in Germany are renovated energetically per year

At least 2.5% would be necessary

Energy systems fail when no one connects the dots.
Property owners don't act - because complexity and costs hold them back.
