Sustainable Design Features

  • Accessible Floors (JPG): All of the city hall systems-ventilation, heat, and wiring are laid under accessible floors.
  • City Hall Terrace (JPG): Another open public space was built above the city hall parking structure.
  • Cork Panels: Cork is a natural renewable material harvested from the outer bark of the cork oak tree every 9 years. It is used in several areas a sound-absorbing wall covering that doubles as a tack surface.
  • Daylight Strategy (JPG): The building's narrow footprint takes advantage of natural light, including the building's stairwells.
  • Daylighting and Views: Occupied spaces are located at the building's perimeter to ensure access to natural daylight and views. High performance glass, skylights, clerestory windows and building orientation maximize the effect.
  • 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.
  • Indoor Environmental Quality: Low VOC paint, sealants, carpeting and other materials were selected to ensure healthy indoor air for visitors and staff.
  • 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.
  • 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 (JPG): More open green space and a throughway from 2nd Street to S Meridian helps to connect City Hall to Pioneer Park.
  • 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.
  • Sunshading: An extended roof edge and sunscreens on the 5th floor and south facade reduce glare and prevent heat gain in the summer.
  • Underfloor Air (JPG): A low-velocity underfloor air distribution system efficiently delivers conditioned, fresh air. Operators fine-tune the volumes for occupied spaces to reduce the building's cooling load.
  • Urban Tree Canopy Renewal: Where originally only 3 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.
  • Water Efficiency: Dual flush toilets and low flow faucets reduce potable water use.
