A professional auditor can personalise your energy audit to prioritise specific savings for your business. The audit template on this page is broader but allows you to identify opportunities to save if you aren't able to engage a professional.
Business energy audits can help you:
- identify the items that use the most energy in your business
- find ways to reduce your energy use and save money.
How to complete the audit
Work through the questions for each type of energy use. You don't need to have sole responsibility for the audit. Sharing audit tasks with your staff can show them you value their input and help them commit to any recommended changes.
All hours audits
A walk-through audit outside of business hours can identify equipment that could be turned off when not being used. For example, overnight or on weekends. You could also vary when you do walk-throughs to reveal how your energy use changes over the day.
Heating, ventilation and cooling
What do you do in the workplace? | What you can do to save energy | ||
---|---|---|---|
Do you maintain your heating and cooling appliances? |
Yes |
No | Follow the manufacturer’s maintenance instructions and have your appliances serviced regularly. This could include regularly cleaning filters, fan blades, grills and condenser coils. |
Is your appliance new and been selected for your building/situation? |
Yes |
No | When replacing an appliance, consider the size of the space and what it is used for:
|
Do you only heat or cool areas that are being used? |
Yes |
No | Close doors to unused rooms so you only heat or cool the smallest possible area. If you have a ducted system, use the zones to limit the areas heated or cooled. |
Are air-conditioned spaces effectively zoned? |
Yes |
No | Check that vents and thermostats are considered when workspaces are moved around - for example, moving office dividers can mean a vent no longer cools the space it was meant to. |
Are ventilation fans turned off when bathrooms are not in use? |
Yes |
No | Install timers or motion detectors to stop unnecessary energy use. |
Are windows or doors closed and sealed in air-conditioned spaces? |
Yes |
No | If you have a reverse cycle air conditioner installed, check that external doors and windows are closed and gaps sealed by:
For larger openings, install automatic door closers, vinyl strip doors, high-speed insulated or rapid roll doors, or PVC impact doors. |
Does your appliance have a thermostat or the ability to set a temperature? |
Yes |
No | Install a plug-in electronic thermostat, which will automatically turn the unit off when the desired temperature is reached. |
Is the temperature on your appliance correctly set? |
Yes | No | Set the temperature to what is comfortable for most people:
1°C warmer or cooler can increase the running costs of your appliance by up to 10%. Limit access to temperature controls so individuals can't set different temperatures. |
Are thermostats placed in appropriate locations? |
Yes |
No | Make sure thermostats are located away from:
Thermostats can interfere with temperature readings. |
Have timers been connected to appliances? |
Yes |
No | Install timers so appliances only run only when required. For example, they turn off automatically after hours, weekends and public holidays. Motion detectors can also start or shut down appliances automatically. |
Can staff manually override air-conditioning timers when working outside normal hours of business? |
Yes |
No | Understanding how to manually override timers and use the correct steps to switch off appliances can help people like cleaning staff save your energy. |
Are you on flat rate pricing tariffs? |
Yes |
No | Switch to time-of-use tariffs and shift heating and cooling to when you're charged at a lower tariff. Automated scheduling can reduce your peak demand. |
In summer, do you shade windows to keep the building cool? |
Yes |
No |
|
Are the outside units of heating and cooling appliances shaded? |
Yes |
No | Protect external units from the elements - For example, add shade from direct sunlight in summer months. But make sure airflow around the unit is maintained. |
Are your ducts insulated? |
Yes |
No | Insulate ductwork . This is particularly important when ducts are located in un-airconditioned areas. For example the roof cavity. |
Have you installed variable speed drives (VSD)? |
Yes |
No | A VSD will adjust the speed of the motor on your cooling and heating systems so it matches your business' need, which is not constant. Talk to a specialist about whether a VSD can be installed into your existing system. New inverter air conditioners generally use VSDs. |
Is the area in front of the appliance clear? |
Yes |
No | Make sure the spaces around appliance vents are not obstructed so that air can flow freely. |
Do staff refrain from using personal heating appliances? |
Yes |
No | Personal heaters can be expensive to run, so find out why they're needed and resolve the problem. If the need persists, request timers are installed so personal heaters aren't left by accident. |
Are ceiling or portable fans used to complement appliances? |
Yes |
No | Ceiling and portable fans are the cheapest types of cooling appliance to run. They create a wind-chill effect. In winter, ceiling fans can help by pushing warm air down from the ceiling. |
Do you make the most of natural cool breezes? |
Yes |
No | Open windows and doors to allow natural cool breezes to cool your site. Use window and screen door locks to keep the site secure. |
Do you use the economy cycle on your air-conditioning unit. |
Yes |
No | The economy cycle uses outside air to cool when external temperatures are close to set temperatures, while purging the hot air. |
Water heating
What do you do in the workplace? | What you can do to save energy | ||
---|---|---|---|
Do you maintain your water heating appliance and fittings? | Yes | No | Follow the manufacturer’s maintenance instructions and have your appliances serviced regularly. Fix dripping taps fixed as soon as possible. Not only do they waste water, leaking hot water taps waste energy too. |
Have you considered different energy sources to heat the water? | Yes | No | Many new technologies and fuel sources are now available. For example, gas, solar, electric, heat pumps. Investigate the options available when your current water heater needs replacing. |
Have energy saving devices been fitted to save hot water? | Yes | No | Water-saving taps, shower heads, flow restrictors, temperature controls (instant gas) and timers all help reduce the amount of hot water being used. Your business might be eligible for free or discounted energy efficiency activities through the Retailer Energy Productivity Scheme (REPS). |
Are hot water saving practices encouraged? | Yes | No | Remind staff to use cold water if hot water isn't necessary. If staff take showers at the site, promote shorter showers and set the temperature between 39°C and 41°C. |
Are external water heater pipes insulated? | Yes | No | Insulate pipes with foam tubing, known as lagging, to prevent heat loss. |
Is your water heater set to the correct temperature? | Yes | No | Many installers will set the temperature to 50°C on instantaneous water heaters. You could turn it down so the temperature is comfortable but specific to the intended use. Stored hot water must be kept at a minimum of 60°C:
|
Is your water heater the right size? | Yes | No | Check that the size of the tank on your storage water heater matches the hot water demand? Continuously heating a large tank for a small amount of hot water will increase your energy use. |
Is your commercial or industrial boiler energy efficient? | Yes | No | Talk to a commercial water heating expert about ways to make your hot water system more efficient or options to replace it. |
Lighting
What do you do in the workplace? | What you can do to save energy | ||
---|---|---|---|
Are work areas appropriately lit? |
Yes |
No | A lighting expert can check that the number and type of lights are appropriate for the work areas. You could also hire a lux meter - measures the amount of light distributed over an area. An electrician can de-lamp light fittings, or install dimmer controls in areas that are over lit. Make sure you tell staff about these changes so they don't replace globes. |
Is task lighting used where appropriate? |
Yes |
No | Task lighting allows staff to set the lighting level for a specific job or workspace. Photosensors can detect the amount of natural light in a room and adjust artificial lighting accordingly. |
Have fluorescent lamps been replaced by more energy efficient options? |
Yes |
No | T5 fluorescent and LED tubes are more energy-efficient than the standard T8. Replace fluorescent tubes and the fittings. Any work must be completed by a licensed electrician. |
Have halogen or standard lamps and downlights, including emergency signage been replaced with more energy efficient lamps? |
Yes |
No | Change your lights to LEDs or other energy efficient options to save energy. Make sure you check with a licensed electrician about which downlights can be changed by you and which need to be professionally changed. |
Have ballasts used in fluorescent lighting been upgraded to more energy efficient options? |
Yes |
No | Install low loss or electronic ballasts. These control how much electricity goes into the fluorescent tubes. |
Have low and high bay lights been upgraded to more energy efficient ones? |
Yes |
No | Upgrade high and low bay lights for longer life lighting. This can also reduce maintenance costs. |
Is natural light used during the day? |
Yes |
No | Move workspaces closer to the windows but make sure windows are cleaned and clear of shading to let the light in. Install skylights or transparent roof panels. Skylights are rated with a U-value and SHGC-value. You should look for the lowest values for each. Remember to consider the amount of heat transfer for these options. Deciduous trees can provide shading in summer and allow natural light in winter. |
Are lights in unused areas turned off? |
Yes |
No | Turn off lights in unused areas. Install motion sensors in rooms so lights are automatically turned off when the area is vacant. |
Is your lighting zoned? |
Yes |
No | If large areas are controlled by a single light switch, ask a licensed electrician to split it into smaller zones that can be lit individually. |
Are signs installed around the workplace to remind staff to turn lights off? |
Yes |
No | Simple and clear signs near light switches can remind staff to turn lights off when they are finished in the area or at the end of the day. Consider running the CitySwitch Green Office ‘switch-off’ campaign with your team. |
Do facility managers or cleaners have a lighting switch off process to follow? |
Yes |
No | Arrange for lights to be turned off at the end of the day by cleaners or facilities managers, depending on who is last in the workplace. |
If you have a freezer or cool room, are lights switched off overnight or when not in use? |
Yes |
No | Turn these lights off when not needed. Cool rooms have a sensor so lights only come on if the door is open. |
Are lamps and fittings cleaned and maintained regularly? |
Yes |
No | Schedule cleaning of light fittings and lamps so light output is maximised. |
Have you put controls on external lighting to limit the amount of time they are on? |
Yes |
No | Install sensor lights or motion detectors so lights turn on with movement and turn off after a set period. Timers can also be installed on outdoor lights. |
Have you looked at power factor correction as a way to reduce your lighting energy use? |
Yes |
No | Power factor correction will synchronise the voltage and current supplied to a load. Speak to a licensed electrician about whether this is an option for your business. |

Are energy efficient kitchen practices encouraged and followed? |
Yes |
No | Reduce kitchen energy use by:
|
Is the cooking equipment insulated? |
Yes |
No | Some appliances (for example warming cabinets, fryers, coffee machines) come with insulation to help keep the heat in. Replace non-insulated equipment with insulated alternatives. |
Are food display cases covered overnight? |
Yes |
No | Using well-fitted blinds or thermal covers outside business hours can help reduce the amount of energy used. |
If your business has different energy price tariffs, are appliances run tariffs are lower? |
Yes |
No | By running appliances, such as ovens or dishwashers, at off-peak times can save on energy costs. If its overnight, see if the appliance has a delay time option. |
Have you investigated installing Variable Speed Drives (VSD) for cooking equipment that use motors? For example commercial mixers and refrigeration. |
Yes |
No | A VSD will adjust the speed of the motors to match the load required. Talk to a specialist about whether a VSD can be used with existing equipment. |
Do you usually run your dishwasher with a full load and at the lowest temperature? |
Yes |
No | Washing a full load means fewer washes overall. You can further reduce energy use and costs by reducing the water temperature. |

What do you do in the workplace? | What you can do to save energy | ||
---|---|---|---|
Are motors, fans, pumps and compressors serviced and maintained? |
Yes |
No | Regularly check equipment to make sure it's reliable and to minimise overall operating costs. For example:
|
Have you investigated the most energy efficient equipment to replace existing equipment? |
Yes |
No | Develop an equipment upgrade plan. Research the total life-cycle costs (ie, energy, maintenance and purchase). Preparing for equipment failure can reduce delays and make sure the most cost-effective and energy efficient models are selected. |
Where an air compressor is used, is the lowest possible air pressure used and is distance between compressor and outlet short? |
Yes |
No | The lower the air pressure, the less energy is consumed. To reduce air losses and energy use, shorten the distance between the compressor and outlet. |
Are air compressors kept in cool environments? |
Yes |
No | Cool air is easier to compress. Locate compressors in cooler areas of your premises. |
Are motors, pumps and fans correctly sized? |
Yes |
No | Over and under-sizing can mean more energy is used than needed. A licensed electrician or specialist can help you work out the best equipment for your needs. |
Is equipment, such as pumps, fans or compressors, turned off when not in use? |
Yes |
No | Encourage staff to turn off equipment or have shut down lists for the end of the day. Install sensors or timers. You could also check if existing controls can be programmed to automatically turn equipment off after inactivity. |
Where fans are used, are they set the lowest speed required? |
Yes |
No | By using the lowest fan speed for the job, you will use less energy overall. |
Have variable speed drives (VSD) been installed to help match motor demand for equipment such as pumps, fans, precision tools? |
Yes |
No | A VSD will adjust the speed of the motors to match the load required and save energy. Talk to a motor specialist about whether a VSD can be used with your existing equipment. |
Has upgrading or replacing existing motors with more efficient motors been investigated? |

Is the use of standby power minimised by turning equipment off at the power point? |
Yes |
No | Make it easier to turn equipment off at the source. For example, power boards can be used for hard to reach switches, or plug-in timers can be used to switch equipment off at a set time. A smart power board that can turn off slave appliances when the master appliance is turned off can also help turn a number of appliances off at once. For example, the computer can be the master and the monitor, printer and scanner can be the slaves. |
Are computers, monitors and other equipment turned off when not in use (for example overnight/weekends?) |
Yes |
No | Screen savers do not save energy. Ask staff to ensure their computers and monitors are turned off when not in use to save energy. Alternatively, see if the equipment can be configured to automatically turn off or go into sleep mode after extended periods of non-use. Consider an out of hours energy audit to find out what is being left on when the building is unoccupied. |
Are laptops used instead of desktops? |
Yes |
No | Laptops generally use less energy than desktops. Consider changing any computers over where possible. |
Are photocopiers, printers and multi-function devices located in a well-ventilated area? |
Yes |
No | Place this equipment in well ventilated areas. This type of equipment can generate heat and make your air conditioner work harder. |
Are the number of printers and photocopiers matched to occupancy? |
Yes |
No | Consolidate the number of printers and photocopiers available. This can often be done without affecting productivity. |
Is printing only used when needed? |
Yes |
No | Introduce a paperless environment to minimise the the use of the printer. Access codes to start the printer can also reduce the amount of wasted printing. |
Are battery chargers for phones, tablets and other personal devices disconnected once the device is charged? |
Yes |
No | Encourage staff to disconnect their device and turn the charger off once it's charged. Most chargers still use a little bit of power once the device is fully charged. |
Clothes washers and dryers
What do you do in the workplace? | What you can do to save energy | ||

Are windows kept shaded in summer to keep the site cool? |
Yes |
No | In summer, close curtains and shade windows facing the sun to minimise heat entering the premises. External shading is also an effective way of reducing unwanted heat from entering the building. |
Are windows kept unshaded in winter so the sun can heat the site? |
Yes |
No | Use the sun to heat in cooler months, particularly through windows facing the sun. It can also be used as a free source of natural light. |
Have you sealed gaps around doors or windows? |
Yes |
No | Use weather stripping, gap filler or draught excluders to prevent draughts. Make sure your choice can tolerate the location and temperature changes. |
Are other areas draught proofed? |
Yes |
No | Shut or turn off openings such as vents and exhaust fans when not in use. Make sure any unused chimneys are also sealed. Installing a reusable chimney balloon means you can remove the seal if you wish to use the chimney again. |
Is the building’s roof a light colour and does it have adequate ventilation? |
Yes |
No | Dark roofs absorb heat. Painting a roof white or a pale colour will help reflect heat from the summer sun. Install a whirlybird or vent in the ceiling to reduce the heat build-up in your roof cavity. Vents that can be closed in the winter are ideal. |

What happens next
- Step 1
Before you make changes
Make sure you record your current energy profile, such as how much you consume out-of-hours or at peak times. This will be your starting point to compare how changes have impacted your business over time.
- Step 2
Check for government and community initiatives for businesses
Many improvements can be made without specialist tools or knowledge but some will require a licensed, qualified specialist or tradesperson.
Check for programs, finance and initiatives that can help businesses save energy, time and money.
- Step 3
After changes
Measure how much you've consumed since you made changes. Compare 'before' and 'after' to see the impact on your energy use.
You might need to make further changes. For example, make minor adjustments to settings or behaviour based on the use of new equipment.
- Step 4
Keep staff informed
Tell staff about the changes you are making and and promote a shared responsibility for saving energy. The more engaged your staff are, the more they’ll support energy saving opportunities.
Where savings are made, acknowledge people who helped make it happen.
