The Mixed Use category features mixed use properties that combine both commercial and residential use. Notable aspects include but are not limited to minimized environmental impact, accessibility to affordable or mixed market-rate housing, use of sustainable building materials, utilization of energy-efficient technologies, plus the integration of walkability, placemaking, and alternative transportation options.
The Green & Main project transformed a complicated site into a successful mixed use building with a health center on the bottom floors and a residential apartment on upper level. It was known that the vacant, commercial building was on the National Register of Historic Places, but work for the geothermal system revealed an additional two historic foundations — a nineteenth century laundry and a Victorian house.
Many regional and community organizations contributed to the success of Green and Main in terms of donations, support, and volunteering. State brownfield and historic tax credit programs were used. An I-JOBS Improved Green Urban Stormwater Best Management Practices grant helped bring soil quality restoration, bioswales, permeable pavers, subterranean retention, a green roof, rain gardens, and rain barrels to the project. Passive and active solar strategies are used, such as double paned windows for the exterior, transom windows for the interior, and solar panels augment power consumption while shading a rooftop deck.

Each room can control its own climate with variable refrigerant flow technology and is supported by a geothermal well. Lighting is controlled by sensors, which feed data to the ISU Center for Building Energy Research. Waste diversion of 90 – 95% was achieved through resale, recycling or repurposing items through site source separation. The building sits on a bus route and has an electric charging station for alternative fuel vehicles. It is seeking LEED Platinum status.
