Impact investing is increasingly popular among institutional investors and private equity funds. What does it mean for office owners? : While impact investing has become trendy among institutional and large private equity investors, it also “makes good business sense,” according to Eric Enloe, managing director in charge of capital markets valuation nationally with real estate services firm JLL. Technology and Fortune 500 companies, which are generating growth in office occupancies nationwide, require environmentally-friendly office spaces, and so are driving this investor trend, Enloe notes.
