Sustainable Design Features
Green Roofs: Demonstration green roofs reduce the heat island effect, reduce heating and cooling costs and provide rainwater management. These solutions are applicable to new and existing buildings in the city.
Rainwater Management: Vertical cisterns, located on the building's exterior, compare rainwater captured by the green roofs to a traditional roof. Rainwater from the roofs and courtyard is collected in an underground cistern.
Irrigation: All planting areas on site are irrigated with re-used rainwater. High efficiency drip irrigation delivers water directly to the plants' roots to avoid waste.
Water Efficiency: Dual flush toilets and low flow faucets reduce potable water use.
Urban Tree Canopy Renewal: Where originally only three trees stood, the project is now home to 81 new trees. The trees provide shade that reduces heat absorption of adjacent buildings and pavements, offsets automobile exhaust, and offers urban habitat refuge.
Natural Ventilation and Operable Windows: Natural ventilation eliminates the need for air conditioning. People are healthier and work more effectively with access to fresh air.
Pioneer Plaza: More open green space and a throughway from 2nd Street to S. Meridian helps to connect City Hall to Pioneer Park.
City Hall Terrace: Another open public space was built above the city hall parking structure.
Daylight Strategy: The building's narrow footprint takes advantage of natural light, including the building's stairwells.
Accessible Floors: All of the city hall systems--ventilation, heat, and wiring are laid under accessible floors.
