The fact-finding mission to Germany for US Architects is part of the "Energy Efficiency - Made in Germany" initiative of the Federal Ministry of Economic Affairs and Energy and is organized by energiewaechter GmbH and the German American Chamber of Commerce, Inc. in New York. Joining the fact-finding mission to Frankfurt and Darmstadt will give US Architects the opportunity to learn about innovative German technologies and services in the field of energy efficient buildings and passive house.
The 12 principles published here are explained in detail in the book Permaculture: Principles and Pathways Beyond Sustainability, by David Holmgren.
In 1978, Australian ecologists David Holmgren and Bill Mollison coined for the first time the concept of permaculture as a systematic method. For Mollison, "permaculture is the philosophy of working with and not against nature, after a long and thoughtful observation."  Meanwhile, Holmgren defines the term as "those consciously designed landscapes which simulate or mimic the patterns and relationships observed in natural ecosystems." 
In 2002, Holmgren published the book Permaculture: Principles and Pathways Beyond Sustainability, defining 12 design principles that can be used as a guide when generating sustainable systems. These principles can be applied to all daily processes in order to humanize those processes, increase efficiency, and in the long term ensure the survival of mankind.
What if we apply them to the design process of an architectural project?
Enthusiasm for water and energy data collection for commercial and residential buildings has been growing strong across the U.S. in major cities such as Austin, New York, Washington D.C. and San Francisco. It's no surprise to learn that Earth-friendly Seattle is ahead of the game when it comes to tracking its buildings; reports show that the city is receiving data for a whopping 87% of its commercial and multi-residential buildings over 50,000 square feet, which totals to 1,160 individual properties covering over 200 million square feet of the city.
