"Relevancy - Shaping Spaces" is the motto of the 14th German Architecture Day 2019 (DAT) on September 27, 2019 in Berlin. Martin Haas is to speak on the topic "Long live the house – save it or forget about it?": "There is a great will to design sustainable architecture in Germany. However, we need to become even more ambitious and courageous while contributing to a significant reduction of CO₂ emissions with our buildings. With Alnatura, we had an investor proving to be this courageous."
