Invitation to June 8, 2013 Calgary ecoHouse Open House:

The flyer shows some of our completed and on-going projects in various provinces of Canada and abroad, from small to large to huge. It is free-of-charge. We try to answer people's questions. We reflect on what works and what does not work, to the surprise of many. We also address issues of durability and maintenance, problems and solutions, challenges and ongoing R&D, based on 36 years of professional work, to improve past technologies, features and products, aspects that few if any, articles, conferences, interviews and tours ever touch.
