Home Energy Self-Audit Checklist
This guide provides you with a simple, step-by-step process that allows you to assess the way you use energy in your home.
By completing the attached checklist you will be able to identify areas where you can realistically make changes to the way you useenergy and save!
How to conduct your audit:
1. Allow around one hour
2. Work through the checklist from A to G, going from room to room
3. Circle the description that closest describes the way that you use energy
4. Add up your stars and add them to the Table H. Energy Action Summary ( = 1, = )
5. Refer to the Suggested Actions Summary column and your Home Energy Audit Booklet
6. Transfer the suggested actions to Table H. Highlight areas that you realistically think you can make changes and note the questionsthat you may have OR list the changes you have already implemented on Table I - Energy Improvement Summary

A. Water heating, shower, bath and taps
Your energy use is closest toHow do you use energy?
High energy use Moderate energy use Energy efficientNotes and suggested actions
What type of waterheater do you use? Electric storage0 Gas Solar, 5-star gas orheat pump
If you need a new hot waterheater, look at solar or 5-star gassystems
Check your hot watertemperature (1)*
65C or more 62C 60C Australian Standards require hotwater heaters to be set at no lessthan 60C. Instantaneous gaswater heaters can be set to lowertemperatures. Internal
thermostats require adjustmentsby a qualified tradesperson. Setthermostats between 60-65C.Turn off your system (includingthe pilot light) when you go onholidays
What is your showers
hot water flow rate?(2)
Greater than 15
litres per minute
12 litres per minute Less than 9 litres per
minute
Install a AAA rated shower head.
How do you showerand bathe?
Long showersand deep baths
Showers only, shallowbath
Short showers (lessthan 3 minutes)
A bath can use over 100 litres ofwater. A short shower can useless than 30 litres
Is there insulation(lagging) on your hotwater pipes?
None0
Some (eg. the first metreonly of the hot waterpipe)
Lagging on cold andhot pipes
Insulate exposed copper pipeswith rubber tubing (lagging) whichreduces heat loss before it gets
to the where you use it. Pipesthat are too hot to touch requirelagging
Your total Total = / 11
(1) If you dont know your thermostat setting place a thermometer under running hot water closest to the water heater, then add 3 degrees if you dont have lagging. Thiswill tell you how hot the water is within the heater before it gets to your taps
(2) Capture water in a bucket in ten seconds, and then multiply the volume by six. Remember to use the water on your garden

B. Clothes washing and drying
Your energy use is closest toHow do you use energy?
High energy use Moderate energy use Energy efficient
Notes and suggestedactions
What water temperaturedo you use?
Always hot or warm Sometimes warm Always cold Most of the energy usedin washing clothescomes from heating thewater. Change to acold waterpowder/detergent. Ifyou need a new washerchoose an energy
efficient unit with a coldwater option. Fill yourwashing machine upwith water from a tapand bucket beforeturning it on. Installaqua-locks and tapaerators on washingmachines. Frontloaders are best
How do you dryclothes?
Always use the dryer Sometimes use thedryer
Always dry on clothesline or on racks
Use the dryer less. Usean extra spin dry beforeusing the dryer. If youneed a new dryerchoose an energy
efficient unitYour total Total = / 4

C. Fridges and freezers
Your energy use is closest toHow do you use energy?
High energy use Moderate energy use Energy efficientNotes and suggested actions
Do you have a secondfridge or freezer?
Always running Only running whenneeded
No second fridge orfreezer
Use your second fridgeonly when needed. Oldunits are less efficient thatnewer ones. If you want toupgrade, choose the mostenergy efficient versionavailable. Install a timeron your beer fridge
Where are your fridge(s)and freezer(s) located?
In a hot spot, exposedto direct sunlight or nextto cooking areas
In a warm part of thehouse
In a cool part of thehouse
Locate fridges andfreezers in cool areasaway from sunlight andstoves
Check your fridge andfreezer temperature (3)
Running at less than3C
Frosts up occasionally Fridge does not frostup
The recommendedoperating temperature fora fridge is 3C to 5C andfor freezers is -15C to-18C. Adjust thethermostats to achievethese temperatures. If youneed a new fridge offreezer choose an energyefficient model
Are your fridge and
freezer well ventilated?
No air gaps on either
the top or the sides
Some air gaps Plenty of ventilation
spaces around fridgeand freezer
Fridges/freezers need
gaps to disperse excessheat. Wipe dust offexposed coils. Ensuredoor seals are in tact anddoors shut automatically
Your total Total = / 7
(3) To measure your temperatures place the thermometer at the back and bottom of the fridge and freezer for two minutes

D. Insulation, shading and draught proofing
Your energy use is closest toHow do you use energy?
High energy use Moderate energy use Energy efficientNotes and suggested actions
Is your home insulated? No Ceiling 2 Ceiling and walls
Insulation is measured by itsthermal resistance. Installinsulation
Do you have shading onnorth facing windows?
None Some Shades summersun only
Well designed eaves shadesummer sun while allowingwinter sun in. Alternatively,install externalblinds/pergola eaves
Do you have shading oneast and west windows?
None Some Well shaded insummer
Install blinds, eaves or planttrees that provide shade inthe summer. Trimvegetation in winter to allowin more natural light
Do you have curtainsand pelmets over livingroom window?
None Good curtains Good curtains andpelmets
Heavy lined curtains andpelmets help keep heat induring winter. Pelmets(covers over the top ofcurtains) are important tostop draughts caused byairflow between windowsand curtains
Are there draughts fromexternal doors,
windows? (4)
Large gaps Some gaps No gaps Use special door andwindow seals. Use door
snakes. Seal aroundskirting boards, ceilings andunused vents. Closechimney vent flues when notin use
Your total 0 Total = / 10
(4) Look for daylight under and around doors or use a lit incense stick and watch for the smoke to move around rather than rise vertically

E. Heating and cooling
Your energy use is closest toHow do you use energy?
High energy use Moderate energy use Energy efficientNotes and suggested actions
How much of yourhome do you heat andcool?
Whole house All living spaces Only rooms thatpeople arein
Only heat rooms that you are currentlyusing. Close doors between rooms notbeing used
What do you use forheating?
Ducted whole ofhouse or manyelectric heaters
Single room heater To warm clothesandoccasionally towarm rooms
Ducted air conditioning, electric barheaters and fan blowers can be veryexpensive to run. Wear warm clothes.Turn heaters off when you go to bed.Set thermostats between 18-21C. Bestoptions are; solar, then gasinstantaneous, then gas storage
What do you use forcooling?
Ducted whole ofhouse
Single room airconditioner
Ceiling fans andnight breezes
Ceiling fans can significantly improvecomfort and work well with airconditioners. Make sure you reversethe fan direction in winter. Evaporative
coolers are cheaper to run thanrefrigerative air conditioners. Highefficiency, zoned systems andevaporative AC units are best. Setthermostats between 25-27C
What is your livingroom temperatureduring winter?
24C or more 22C 20C or less Lowering the thermostat of heaters byone degree can reduce energy use by10%
What is you livingroom temperatureduring summer? (5)
21C or less 23C 25C or more Raising the thermostat of coolingsystems by one degree can reduceenergy use by 10%
Your total 0 Total = / 7
(5) Place a thermometer near where you spend most of you time. If you can read the thermostat setting on your heater/cooler it may be different to the temperaturewhere you sit to watch TV for example

a day and regularlycleaned
No pool Consider a solar pool heater and blanket.Keep filters clean. Salt water chlorinators can
double energy use
