2016 Mixed Use Winner :: Green & Main :: Indigo Dawn

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.

Green & Main, Des Moines, Indigo DawnThe  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.
Green & Main, 2016 mixed use winner, before, des moinesMany 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.

2016 Renovated Commercial Winner :: Market One Building :: Blackbird Investments

The Renovated Commercial category highlights the use of existing structures for commercial purposes. Sustainable qualities include but are not limited to the use of salvaged materials as well as sustainable building materials, utilization of energy-efficient technologies, the adherence to historical preservation practices if applicable, plus the integration of walkability, placemaking, and alternative transportation options. Projects that solicit and implement community feedback are also valued qualities.

2016 Best Development Awards, winner, Renovated Commercial, Market One, Blackbird InvestmentsThe Market One Building, located in Des Moines’ East Village, is on the National HIstoric Register and used state and federal tax credits to restore and repair 97.8% of the structure, floors, roof, and building envelope. It adaptively reuses a factory for commercial space. A glass-enclosed conference room and 3000 square feet of deck and shade canopy were added to the roof.

The remainder of the roof was covered with photovoltaic panels and a planted (green) roof system. Additional primary sustainable building elements include: mini-rain gardens, native and perennial plantings, and capture and delay water retention; geothermal heating and cooling technologies; solar photovoltaics on the parking canopy (with the roof array, the building has net-zero status); dual flush toilets; permeable walk surfaces; maximized daylighting, LED lighting, sensors and lighting controls; dedicated parking for HOV workers and four charging stations for electric vehicles; and showers at each floor level. The combination of geothermal and solar energy sources along with LED lighting and an advanced refrigerant-based heating and cooling system has allowed project to achieve net-zero energy usage. The project is LEED platinum eligible.
