Passive House for All – 21st International Passive House Conference, Vienna, Austria First, what a great city for a conference. Great architecture from many eras, walkable (6 miles most days), easy transit, and great food and beer. Second, I need to thank the West Penn Sustainable Energy Fund, Passive House of Western PA (PHWPA), and the Green Building Alliance (GBA) for selecting me and my six fellow trainer candidates for Certified Passive House Designer/Consultant training
