Sustainability & the passive house standard – Bahnstadt Heidelberg

https://www.heidelberg.de/1046866.html

In terms of sustainability, Bahnstadt is pursuing an ambitious concept. Heidelberg’s newest district is home to nothing less than the world’s largest passive house settlement. All buildings in the new district are constructed in compliance with the strict “passive house” energy efficiency standard. The energy requirements for properties designed in this way are 50-80% lower than with conventional types of residential buildings. Energy monitoring in Bahnstadt by the Passive House Institute in Darmstadt shows that targets are being met. The residential buildings studied require on average just 54 kilowatt hours per square meter per year of district heating for all applications (heating, hot water, distribution and storage losses) – a very respectable carbon footprint.
