Big Win for 24 Stories, Energy Efficiency Retrofit in Phoenix, AZ

The BOMA Green Building Committee Kilowatt Krackdown was recently awarded to 3200 N. Central Avenue – a retrocommissioned, 24 stories, 345,000 SF building in Phoenix AZ built in 1986 – for achieving the highest Energy Star score of 98 in the competition. 
Tim Rose, Executive VP of DPC companies commented on the need for SMARTPneumatics technology. “Prior to the retrocommission, our heating and cooling expenses for the existing building were substantial. That, combined with tenant complaints about cooling issues during the summer, and the resulting tenant comfort, work order requests made it clear to us that we needed to improve the building’s HVAC. We are very pleased with the upgrade, as are the tenants.” 
The energy savings gained were attributed to implementing a combination of low cost best practices and equipment replacement projects:
  • Using SMARTPneumatics to complete a major VAV retrocommissioning that included repairs to air leaks in the pneumatic system, re-calibration, and actuators for improved air flow correction. Energy use was reduced by 160,000 KWH per year.
  • Two 50 HP, high efficiency motors were installed for the condensing loop and one VFD was added to a motor.
  • During the main lobby remodel, new 12-watt LED flood lights were installed which replaced 50-100 watt incandescent fixtures.
  • The exterior landscape remodel added 30 10-watt LED fixtures and lamps outside, replacing 50 watt halogens.
  • Timers were installed for all drinking fountains.
