The grass is very green on the sustainable-living landscape, but getting there can be a challenge. The Chicago Architecture Foundation presents an opportunity to learn from the experts—Tom Bassett-Dilley, architect; Marko Spiegel, CTI; and Mary Chris Jaklevic, homeowner—who built the Jaklevic/Schuster passive home (pictured) in Oak Park. Team members describe building an ultra-efficient, furnace-free house on an urban Chicago lot and will explain how superinsulation, solar orientation, an airtight shell and mechanical systems all factored into the energy-conscious design. And as one year has passed since the home’s completion, they will also discuss how furnace-free felt during last season’s brutal winter weather. Register here for the workshop, $5 for members, $7 for non-members. Saturday, September 10, 10 a.m. – 12 p.m., Lecture Hall Gallery, Chicago Architecture Foundation, 224 S. Michigan Avenue.
