Solar PV panels are now being installed on rooftops as the second "switch" of the Pow- erswitch program. Powerswitch began with upgrades to HVAC systems, par- ticularly motors in the college's original buildings. Next came more efficient lighting through aggressive conversion to efficient LEDs (including parking lots). Housekeeping services, once per- formed at night, are now com- pleted during the day so building temperatures can be adjusted to save energy overnight. Most campus rooms are now fitted with motion sensors. Retrocom- misioning is currently underway, which includes chiller optimiza- tion, HVAC system rebalancing, equipment replacement, and instituting a more robust build- ing automation and scheduling system. JCCC currently has 242kW of photovoltaic solar power throughout campus which is paired with student learning opportunities. A plan of retrofitting most roofs with solar is underway in stages. Further, JCCC students have built five solar charging tables on campus. ADVERTISEMENT
