Hunzinger Construction Corporate Headquarters Renovation is located at 21100 Enterprise Avenue in Brookfield, WI. Hunzinger served as design/builder for the 5,300 square foot renovation that was the first ever project in the State of Wisconsin to achieve LEED-CI Gold. Hunzinger set out to create a more centralized Estimating department, maximize the existing space for the Accounting department and project management support personnel, update the HVAC system to provide better temperature control for occupants and create a more energy and resource efficient building.

The result was a project that achieved all those goals and the LEED-CI Gold certification by reducing water use by 30% using waterless urinals, low-flow toilets, and low-flow, sensor operated lavatory faucets, using high efficiency recessed direct/indirect fixtures with T8 lamps that achieved greater than an 18% reduction in lighting power density, using dual level switching, automatic shut-offs, and photo-sensing dimming and replacing the HVAC system. Private offices have zone damper and adjustable zone sensors and open interior areas have three zone dampers. On the construction side, 89% of the construction and demolition waste recycled and diverted from landfills.

“For us, this is the project that started it all. John Hunzinger had challenged all our professional staff to obtain LEED Accredited Professional status. As our staff began studying and taking the LEED AP test, our owners decided that we needed to learn, hands on, about LEED construction. We had one of our Project Managers, who is an Architect, draw up the remodeling plans for our office renovation. The project did prove to be an incredible learning experience for all of our staff and our project became the first ever in the State of Wisconsin to achieve LEED-CI Gold. With John Hunzinger’s vision and the completion of this project, the trajectory of this company was changed as we became true leaders in green building practices.”
