Green Building and Geothermal Energy Advisor, Founder of GPF Building Solutions and Native Geothermal

Perhaps it was his first job mowing lawns at age 11 that began Immel on a path toward green, sustainable living. His company consults with property owners to assess energy performances of homes, businesses or investment real estate. Utilizing the latest technology and financial analysis techniques, Immel helps property owners make building, construction and renovation decisions that improve both “the bottom line and the environment,” as he says. In fact, Immel is one of the only LEED- (Leadership in Energy and Environmental Design) and IGSHPA (International Ground Source Heat Pump Association)-accredited building professionals in the world. When it comes to volunteerism, Immel prefers to devote his time to green building and sustainability-oriented groups. “Their educational missions are important to me, and ultimately help create a better-informed market for my businesses’ products and services,” he says.
