Effective M&O Practices Increase Efficiency

Well-designed M&O program can generate substantial energy savings for your district, in both new and older buildings

Federal Energy Management Program (FEMP) Operations and Maintenance Best Practice Guide – “It has been estimated that M&O programs targeting energy efficiency can save 5% to 20% on energy bills without a significant capital investment.”

Energy Saving Strategies

Scheduled Maintenance – reinstate required maintenance procedures for filters, boilers, etc

Simple Repairs – Low-cost repairs that can be completed by in-house staff

Equipment tune-ups and calibration – can extend the life of equipment

Equipment Control – limiting equipment operation exclusively to occupied hours, developing proper procedures for after-hours, weekends.

District Events Calendar

■ Reduces school’s time manual scheduling

■ Reduces labor time & costs

■ Reduces energy costs due to increased efficiency

■ Reduces risk of human error

■ Increases likelihood of satisfied users

Event Driven Automation

Benefits Savings

Energy savings by enhanced mapping of occupancy to conditioning

Energy savings of 3% +, typically $9/student/yr

Operational savings thru automated process

Operational savings typically $6/student/yr

Increased cost recovery thru district invoicing

Avg. cost recovery $15 /student /yr

Total estimated savings of $30 per student per year

How does this compare to how things are happening now? Individual buildings are scheduled on a master

calendar – Buildings remain in a occupied status

– Manual overrides occur to accommodate after-hour events on some cases

Scheduling is EVENT driven and automatic – takes out human error and potential changes in start/stop times
