The German university town of Heidelberg is developing a near zero energy neighborhood, housing 5000 people and providing jobs for 7000. All the buildings will meet the ultra strict Passivhaus energy efficiency standard. It’s in the center of town, and will be extremely well served by transit, with easy bike and pedestrian access to the rest of the city. This would be a great thing to see in, say… the Diagonal Plaza. More info on the development here. 93% of the unites are already sold…
