Schools District 35 - Continuous Optimization and Power Factor Correction
SD35 Walnut Grove High School C Op
E-Factor performed an Optimization project at Walnut Grove Secondary, the largest High School in the Langley School District. We worked closely with energy management and maintenance staff to add control sequences and trim existing schedules to save and estimated 8% of electrical and fuel consumption for the facility, which was already very low energy. E-Factor completed the project including 4 quarterly Coaching Sessions to review the installed conservation measures.
Power Factor Correction
Subsequent to the Optimization project SD35 hired E-Factor to help resolve a low Power factor problem which resulted in a $9,000 annual penalty. E-Factor analyzed the related electrical active and reactive power and designed and specified a low cost solution with a combination of fixed and variable (DDC controlled) capacitor banks. The payback for the project including engineering is less that 3 years.
Thank you to SD35 Debbie Sansome and Robert Mainville, and to Grant Leese of VIE Industrial Electrical for their assistance with this challenging but successful project.
