Commercial real estate giant CBRE just dedicated 34,000 square feet to showing off its eco-friendly chops.

Its client experience center near Milwaukee, which debuted this spring, is a showcase for all the sustainable and green technologies. Here, the company can test out tools to make life better for its office tenants and lower operating costs for its owners.

Developed in 2010 as simply a headquarters for CBRE’s own team, the uberhigh-tech building is still an active office building — just with tons of fancy features that can be replicated for clients across the world.

Sure, there are lots of solar panels. But there’s also smart lighting. If an employee enters the office early in the morning using a key card, lights will turn on only in the area where he or she sits.

Throughout the day, light levels are automatically controlled based on the ambient light from the windows, while specially calibrated air is pumped in based on measured carbon dioxide levels.

“We consider the building a living lab,” says Joseph Feuling, the CBRE vice president who runs the facility.

Alerts are also sent to the building management team when an emergency defibrillator or fire extinguisher is removed — and even if something is blocking them.

Another tool can even monitor the status of conference room projectors so that their bulbs can be replaced after 90 percent of their useful lives. That way, important presentations are never interrupted.
