Epping Secondary College Reduce Energy Use By 60%

At one of the 10 locations upgraded across NSW, Victoria, South Australia and Queensland, Chep upgraded the lighting in their warehouse and outdoor yards at Erskine Park to reduce lighting energy use by 70%.

The Project

A large school in the northern suburbs of Melbourne, with students from year 7 through to year 12, Epping Secondary College undertook a lighting upgrade across the entire school. Following an energy usage analysis, significant energy and maintenance savings could be found by upgrading to energy-efficient LED lighting to replace the existing lighting. The quality of light would also be improved.


Throughout the classrooms, library, auditorium, basketball court, offices and hallways the existing lights were upgraded to LED tubes and LED highbays. A substantial reduction in total lights was achieved, replacing 2,224 with just 1,133.

The superior light globes create a more comfortable learning and working environment for the students and teachers.

A little known fact is that the LED’s produce much less heat allowing a further contribution to comfort and savings through less cooling required.


The exterior lighting covering walkways, courtyards and large open areas consisted of a mixture of metal halides, incandescent, halogen and CFL globes. These were replaced with LED flood, LED tube and LED bunker light fittings.

The higher-performing replacements allowed for fewer globes, with the 277 existing lights replaced by only 212.

Key Benefits of the Lighting Upgrade

  • Rebates of $38,400 achieved through Government incentive schemes.
  • A total of 2,501 lights were replaced with 1,345 energy-efficient LEDs.
  • Longer lifetime of LED expected to deliver maintenance savings of $7,760 p.a.
  • Energy usage reduced by 60% saving an expected $31,380 p.a.
  • Total payback period of just 3.3 years.

1.How much am I going to save?
For customers with an electric hot water system, customers should see an 80% reduction in costs based on the average use of an electric storage system.
2.What size do I need?

A 155L heat pump is suitable for 1-3 people,  215L will cater for 4-6 people. If you need larger, talk to our team about a dual-system installation.

3.How much will it cost me?

Pricing is calculated based on the rebates made available by the South Australian and Victorian governments, and the work involved with relocating your hot water system outside (if applicable).

4.If it runs all the time, won’t it be expensive to run?

The current electric system you have has an element in it that is extremely inefficient and expensive to run which results in greater costs. While heat pumps are running all the time, the compressor fan only really kicks in when it needs to be refilled, the water that is sitting in the tank will stay hot until its next use or the tank needs to be refilled.

5.What if I need a bigger tank than a 215L heat pump?

While electric tanks get drained and refilled at night, heat pumps work all throughout the day. Once water reaches a certain level in the tank, the sensor will trigger and automatically start refilling the tank and heating the water at the same time. The tank will take 1-3 hours to refill and heat the water if it is completely drained. It’s only really when 6 people take showers back-to-back that the tank will require to be refilled but this is not how most people use their hot water system. If you are concerned about the capacity, please talk to our team about the possibility of a dual-tank setup.

6.When will the upgrade get done?

Bookings are being made in groupings so our installers will be in contact with you as soon as we have enough work in your area.
