Moist air filled greeted us as we awoke from our second slumber at the world's first KOA. After downing store-brewed coffee, we geared up for a jam-packed day of green building education. Yesterday's Exxon Mobile tour left us with the realization that corporate culture can be hard to change. “Business as usual” is obviously the path desired, and I felt a bit down about the corporate stronghold on America's energy portfolio. Thankfully, today, we had the opportunity to share the day with Ed Gullick, a visionary architect here in Billings, Montana, who showed us how changing the way our buildings are designed can be a valuable weapon in beating that culture.
