Tips on how you can save energy for your business
1. Reduce or eliminate instances where electricity is being used to light empty spaces during and after business hours.
2. Install timers to switch electricity on and off.
3. Install movement sensors for conference rooms and offices to reduce energy consumption when the space is not being used.
4. Consider using movement or infrared sensors to reduce electricity consumption whilst increasing security.
5. Consider replacing incandescent bulbs in items such as emergency exits or illuminated signage with LED’s.
6. Consider replacing incandescent or halogen lighting with energy saving lighting such as fluorescent bulbs and LED’s. Alternatively, consider low-voltage halogen lights.
7. Clean lights regularly of dust to ensure their longevity via reduced heat and they remain bright.
8. Place reminder notices next to appliances such as photocopiers requesting staff turn off the appliance at the end of the business day.
9. Consider including a new buisness practise where staff would be required to turn off all computers and monitors at the end of each business days.
10. When purchasing new computers, consider the financial viability of laptops rather than desktops as they consume less energy whilst encourage productivity.
Heating and Cooling
11. Each season adjust your heating and cooling. It is common to set the thermostat to between 18° and 21° in winter and 24° in summer. Note that each degree cooler or warmer can add more than 7% to your total energy bill.
12. Close off vents in unused areas.
13. Ensure thermostats are not located near a draught or frequently used exit doors.
14. When selecting a thermostat, choose one with timer settings so that the building is not heated or cooled when the office is unattended.
15. Consider insulating the building, particularly the ceiling as that is where outside temperatures penerate the building most.
16. Consider installing window shades, solar reduction film or awnings to reduce heat entering the building.
17. Open doors and windows when outside temperatures are comfortable to take advantage of fresh air and reduce energy usage if the thermostat is set correctly.
18. When installing refrigeration, consider stock requirements prior to purchase.
19. Ensure fridges and freezers are located away from heat sources (including sunlight) and that there is adequate airflow around motors, compressors and vents for hot air to escape.
20. Re-stock fridges and freezers at the end of each day and fill cool rooms with as much stock as possible to reduce the cold air lost when doors are opened and reduce the energy required to cool the fridge to the right temperature.
21. Clean all refrigerated units regularly for efficient operation and maintainance of good hygiene. Ensure all fans, motors, and other moving parts are cleaned and dust and ice removed.
22. Check all hinges, catches and sealing strips are in working order and undamaged as gaps allow cold air to escape.
23. Install air curtains or plastic strips in cool rooms to reduce hot air entering the room.
24. Turn off lighting overnight for fridges and freezers to reduce the cost of the lighting and the need to reduce the heat generated by the bulbs.
25. Use thermal covers on fridges and freezers at the close of business to reduce the energy required to keep stock cool.
26. Choose a hot water system based on expected usage.
27. If fitting out your business, consider the positioning of your hot water system/s. Consider where the most usage is going to occur and install the systems as close to the outlets as possible to reduce the time it takes for hot water to travel from the taps and the amount of water the system has to heat.
28. Install electronic sensors on taps and low-flow nozzles on showers and taps to reduce wastage.
29. Insulate hot water pipes to reduce heat loss and increase the efficiency of the hot water service.
30. If hot water is only used occassionally, consider using an instantaneous hot water service which only consumes energy when in use.
31. If more than 80 litres of hot water are consumed daily, consider a solar hot water service to use the sun’s energy instead of electricity or gas.
32. Re-setting the temperature of the hot water system by up to 10 degrees lower than the factory setting could save more than 5% in energy usage costs.
33. When the business is closed for extended periods, ensure the hot water service is turned off.
34. Fix leaking taps as soon as identified as they can waste up to 1,400 litres of water per month. Further costs are incurred if it is a hot water tap.
35. Check for faulty pressure or release valves during regular service.
