Steven Cox

In his eyes, it is the charge of this generation of Albertans to fully embrace the role of problem solver. Steven believes Passive House Alberta can inform others about how and why buildings are built the way they are. He wants people to get as excited about the less visible features within a building envelope as they are about cabinets, countertops and paint colors.
