The success of a Denver school's consultation with Xcel Energy shows how technical advice from utilities can assist in energy upgrades. Starting with small improvements and considering a building tuneup are among the lessons learned in such consultations.
At Castro Elementary School in Denver, staff and students complained that it was too hot at times and too cold at other times. Because the building was relatively new, it didn't need new equipment, so the Denver Public Schools sustainability department worked with Xcel Energy to determine how the building could operate as efficiently as possible. The answer was recommissioning.
The project showed several opportunities for energy savings, including a VFD retrofit and tune-ups for the chiller and air handling units. Xcel Energy awarded Denver Public Schools a $10,900 rebate for implementing some of the energy efficiency measures identified by recommissioning. If the school moves ahead with the rest of the measures, it will receive an additional $37,095 in rebates.
"By tuning up the various systems in the building and making sure settings were optimal, we could help the school save money but more importantly, provide a comfortable setting for students, staff, and faculty," says Melanie Gavin, Xcel Energy account manager.
Facility managers can take away multiple lessons from both projects, explains Karen Rhodes, Xcel Energy energy efficiency marketing manager:
