Cedar Rapids Public Library

CRPL_3_3x2Ament provided the civil engineering site design for the new Cedar Rapids Public Library across from Greene Square Park in downtown Cedar Rapids.   This project symbolizes the City’s recovery from the flood of 2008. This new facility includes an auditorium, a café, conference center, and a green roof with skywalk connection to an adjacent parking structure, designed by OPN Architects.

Sustainable feature in this innovative facility include:

  • Geothermal heat pump and chiller plant serving VAV distribution system with overhead on first floor and underfloor distribution on the second floor, and electrical daylighting controls.
  • 10,000 gallon cistern on the building roof for rainwater harvesting
  • HVAC geothermal system condensate collection system which pumps excess condensate into the on-roof cisterns
  • Green Roof irrigated by on-roof cistern
  • Pervious pavement in the parking and patio areas with underground subdrain system connecting to nearby tree pits for irrigation
  • Roof rainwater runoff overflow that is not captured by the cisterns and green roof, and parking area runoff that is not captured by the pervious pavement is collected in a Stormtech Underground detention chamber and allowed to infiltrate back into the groundwater system
  • Doppler ultrasonic water meter installed in the Stormtech underground detention chamber stormwater overflow pipe to measure quantity of off-site runoff. Performance from meter to be displayed on an interactive sustainable design features kiosk inside the library building.
  • Harvested rainwater used for irrigation for the green roof
