NAI HIffman is the top property manager in the Chicago area by SF (200+ buildings), so we've tapped managing director Bob Assoian for Bisnow's Property Management & Sustainability Summit on Aug. 28. Suburban trends he's seeing: condensed, collaborative offices putting a strain on parking (some companies now look for five to six spaces per 1,000 SF); more Energy Star momentum than LEED, as it requires less capital investment; and a ramp up of institutional medical office trades. Their biggest competitor today is self-management, Bob says. Recent suburban office buyers are boutique firms who are likely to self manage. "Our job is to show them how hiring us to manage adds value and brings synergy," he says.
