Yesterday, US Green Building Council Chicago chapter held its annual Natural Leaders luncheon at the Hyatt on Wacker Drive. Keynote Andrew Winston (co-author of Green to Gold) talked about how companies can leverage green technology to make profits since the climate change industry will be a $2 trillion business by 2020. USGBC's Kelsey Mullen joined Architectural Energy Corporation's Kristin Shewfelt  and Paul Sobiski, who?re renovating affordable housing with stimulus funds in Albuquerque and Denver.

Superior Spaces' Jason Berry, Laten Design's Katherine Darnstedt, and Jones Lang LaSalle's Adam Cook are making an impact, too. JLL worked on the first multi-tenant LEED Platinum building, at 550 W. Washington and is in the process of retrofitting the World Trade Center, while Jason worked on the first LEED-Certified MOB in the city, a Silver building on Lake Street in Austin. Katherine's company just built a community center in Ghana and is hoping to get an assignment for one on the South Side soon.
