Billing itself as the "Greenest Hotel in America," the 147-room luxury Proximity Hotel uses 40% less energy and 30% less water than a comparable hotel.The 55,000-square-foot building features precast concrete walls with continuous insulation for thermal efficiency and reduced heating/cooling costs.

Precast was manufactured within 100 miles and resulted in near-zero construction site waste. Concrete used 20% fly ash. Plant-manufactured precast helped reduce harvested materials, site noise, and dust. Cement contained 4% to 7% preconsumer content. Other sustainable attributes include:

  • Regenerative drive elevators that generate electricity as they are descending
  • Low VOC paint, adhesives, and carpet to reduce indoor air pollution
  • Use of solar roof panels to heat 60% of the hotel's water
  • Use of a ground-source heat-pump refrigeration system
  • A large stream on the project site was restored, creating a self-sustaining system that rebuilds wildlife habitat, aids in flood prevention, and helps with erosion and sediment control.
