PHASE 1 PHASE 2

SOLUTION

▪ Demand alert tracker (Greensense)

WHAT WE DID

▪ Monitored consumption and provided demand alerts via our Demand Tracker software

▪ Armed staff with information to help them better understand their electricity charges

▪ Developed an action plan for making quick and easy energy savings

RESULTS

▪ By switching off lights and air conditioners in unused parts of the school, the school saved about $10,000 across the summer months

AN ELECTRICITY PROFILE EXAMPLE.

YOUR ACTIONABLE ENERGY FRAMEWORK.

Practical steps to take

Engage the

school

community to

participate

Check lighting to see

if a LED lighting

upgrade is suitable

Check all HVAC Units are set

at optimal temperature

Make sure computers &

computer screens are shut

down over night

Check scheduled maintenance

on key equipment e.g. hot

water, fridges, pool pumps

Engage P&C for

support

of energy

investment plan

Partner with an

expert to help

with your long

term energy plan

DRIVING BEHAVIOUR CHANGES.

Develop a practice of saving

energy by implementing checklists

to turn off appliances and

equipment when not in use.

Out of hours usage could be

driving a significant % of your

energy costs.
