Warren Lloyd argues that his job is not to promote but advise people on the latest building technology. But like it or not, he is proving through super-sized geothermal systems that sustainable air-handling can generate cold cash.
A health-care owner recently took Lloyd up on his idea to build the nation’s largest geothermal pond for a $310-million replacement hospital in Elgin, Ill. Administrators were skeptical at first. But the vice president of Rock Island, Ill.-based KJWW Engineering Consultants in 2000 already had proven out the nation’s second-largest lake loop at the Great River Medical Center in West Burlington, Iowa.
