Chicago, like several other cities, has a Green Permit Program (PDF) that grants faster building permits for green buildings. Erik Olsen, the program’s administrator, gets to scrutinize every single green building in the entire city. Luckily for us, Erik recently started GreenBean, a blog profiling the blueprints that cross his desk.

So far, he’s posted eight building profiles, including two single-family houses (both in my neighborhood — must be my aura), high-rise offices, and the rehab of a YMCA into subsidized housing. For each, he notes the level of green-ness, unusual green techniques used, and perhaps a little back story about quirky geothermal wells or an underappreciated project manager who pushed the green angle.
