I recently learned that Sim van der Ryn passed away. Sim’s work influenced me greatly. In the mid-80s I was studying passive design architecture at CSU Sonoma and was affiliated with the <a href="https://www.pressdemocrat.com/article/news/photos-occidentals-farallones-institute-championed-sustainable-living/" target="_blank" rel="noopener">Farallones Institute</a>. I also was the last caretaker/tour operator of the <a href="https://en.wikipedia.org/wiki/Integral_Urban_House" target="_blank" rel="noopener">Integral Urban House</a> in Berkeley, California. For some strange reason I remember one Farallones Institute Board meeting he had arranged to be  held on a houseboat in Sausalito. The last saw Sim at the <a href="https://stalberg.net/farallones-institute-40th-reunion/">2019 fortieth reunion</a> of the Farallones Institute.
