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 Farallones Institute. I also was the last caretaker/tour operator of the Integral Urban House 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 2019 fortieth reunion of the Farallones Institute.
