5 (Passive) Ways to Keep Your Cool at Home

Passive cooling is the least expensive means of cooling a home in both financial and environmental terms. It focuses on heat gain control and heat dissipation in order to improve the indoor thermal content with low or no energy consumption, it’s natural air conditioning.

1. Insulation

Insulation is the most effective way to improve the comfort and energy efficiency of your home. A fully insulated home means you'll spend less on heating in winter and cooling in summer.

2. Draught proofing

Draught proofing, or sealing up gaps and cracks, will minimise the amount of heat entering your home and reduce your cooling bills.

3. Window design, orientation and coverings

Windows can let a lot of heat into your home during summer, especially if you have large west, east and north-facing windows that aren't adequately shaded. Discover simple steps to reduce heat gain through your windows here.

4. Ventilation

Ventilation is an important way to regulate your home's air temperature and keep it free of condensation build-up. Once the temperature starts to drop in the evening, or after a cool change, it's important to open your doors and windows to flush warm air from your house and allow cooler outside air to enter. The benefits are likely to be greatest if you open doors and windows facing the breeze and also doors and windows on the opposite side of the house.

5. Landscaping

Careful selection and positioning of plants can provide summer shading and act as a buffer against hot winds. Tall, deciduous canopy trees provide shade to north windows while still allowing the lower winter sun through. Smaller, deciduous shrubs are useful for shading east and west windows and walls. Deciduous creepers over a north-facing pergola will provide shade for windows and walls.

Save Energy, Boost Comfort with Scorecard

The Scorecard is a new government program to help you reduce energy use in your home, and keep yourself cosy in the process.

Scorecard looks at the way your home is built and insulated, and features like your hot water and heating systems. It is delivered by government-accredited assessors, who give your house a star rating (like the star rating on your fridge or air conditioner) and recommendations for upgrades.

Getting a Scorecard assessment is simple. Visit the website – www.victorianenergysaver.vic.gov.au/scorecard - and contact an assessor for a quote.

For more information, email help.scorecard@delwp.vic.gov.au or call 136 186.


Energy Efficiency at Home

As the temperature starts to drop and you begin the annual quest to find your hot water bottle, we wanted to bring you the hot tips to reduce your energy costs, while increasing the comfort of your home. 

These are the quick wins that have minimal cost, require minimal effort and result in big dollar savings. 


  • Keep the thermostat below 20°C. Every degree higher will increase running costs by around 10%.
  • Close off rooms not in use so you only heat the rooms you are using.
  • Turn the heater off overnight or when you go out, don’t leave it running.
  • Seal up any gaps and cracks under and around doors and windows, use draught excluders and weather stripping on doors and windows, cover evaporative cooler outlets, seal wall vents.
  • If you are going to buy a new heater use the energy rating labels to upgrade to a high efficiency heater.

White Goods

  • Turn off that second fridge when it’s not needed
  • Check your fridge and freezer seals, clean and replace damaged seals.
  • Check that the heat exchange coils at the back of the fridge are clean and well ventilated.
  • Wash clothes with cold water whenever possible
  • Only run your dishwasher when it’s full.

Hot Water

  • Take shorter showers; use a shower timer to make sure everyone has a four minute shower.
  • Install a low flow shower head and save water and energy.
  • Insulate hot water pipes leading from your hot water system into the house.


  • Use natural lighting wherever possible.
  • LEDs use much less energy to provide the same amount of light as other forms of lighting. 
  • Switch the lights off when you leave the room and in rooms that aren’t being used

TV and Home Entertainment

  • Turn the TV and entertainment appliances off at the wall when they’re not being used. They are still drawing power in standby mode.
  • Install a ‘standby-killer’ switch or a standby power controller (SPC) to disconnect power to appliances when they’re not being used.


  • Only heat the amount of water you need, if you are making a cup of tea for one or two don’t overfill the kettle.
  • Keep lids on pots and pans when cooking and use the right sized pot for hob.
  • Cook in bulk and freeze the excess.
  • Use the microwave for cooking whenever you can, but switch the clock off. More energy is used to power the clock than to cook food.

Additional tips

  • If you do need to upgrade any appliances, choose ones that have a high energy rating. 
  • Appropriate window protection creates an insulating layer of still air on the inside of the glass. This can be achieved by the addition of thick curtains and a pelmet.
  • Using rugs helps to prevent heat loss.

Smarter travel options

A comprehensive transport system is at the heart of a liveable community, making it easier for all of us to go about our daily lives. The City of Port Phillip is committed to delivering an integrated transport network that connects people and places.

Limited parking availability and increasing congestion on road networks, makes driving cars increasingly unviable. However, City of Port Phillip has safe, attractive and viable transport alternatives

Choosing sustainable transport options (walking, cycling, and public transport) has numerous social, economic and environmental benefits:

  • Healthier, more active communities 
  • Socially connected, more liveable communities
  • Reduced greenhouse gas emissions.
  • Transport efficiency and reduced space required for vehicle movement and storage
  • Accessible for all members of the community
  • Improved safety for everyone all road users

Here are some examples of the environmental impact we can all make by choosing a sustainable travel option. 


Walking helps keeps us fit and healthy and is a great way to exercise for all ages. If you walk rather than drive for 30 mins you would reduce carbon emissions by 1 kg. 


Bikes cost nothing to pedal and they generate zero carbon emissions. A 10 km daily bike commute would save 1500 kg of greenhouse gas emissions a year.

Public transport

One full bus can take more than 50 cars, and their emissions, off the road.

Reduce your carbon emissions

Australia ranks among the highest carbon polluting countries in the world. Making simple changes in our daily lives – at home, in our shopping choices and even how we travel – can reduce our carbon footprint and save you money too. Here's some simple tips to that will make a big difference. 

1. Save up to 20% of your household electricity consumption by switching off and unplugging unused lights and appliances. 

2. Energy efficient lighting, like LED and fluorescents, can halve your lighting energy use.

3. Choose appliances with high energy efficiency ratings, each star represents up to 20% greater efficiency.

4. Switch on to clean renewable energy, choose a provider that is renewables friendly and purchase their 'green power' product. 

5. 40% of household energy in Australia is used in heating and cooling homes. Reduce your reliance on appliances by;

  • Keeping windows shaded
  • Insulating walls, ceilings and floors
  • Draught proofing your home

6. Going solar at home means saving money on electricity bills and reduces your carbon footprint. Over 2 million Australian homes are already powered by the sun. 

7. Transport accounts for 34% of Australia's total household greenhouse gas emissions.Reduce air travel where you can. Drive less, and opt for public transport, walking, cycling or carpooling instead. If you must drive, then consider a hybrid electric vehicle or offsetting your emissions.

8. When shopping make environmentally friendly choices. Buy recycled, shop local, buy less meat, choose biodegradable products, avoid product packaging that ends up in landfill and of course where possible don't buy new products. 

9. Minimise your food waste by planning your shopping and meals more carefully, re-using leftovers and composting. 




Reduce your water use

Reducing water consumption in the home is a simple and easy way to decrease water and energy bills and lessen your household’s impact on the environment.

Conserving water resources, even in areas without shortages, has many benefits;

  • lowers energy requirements for treating and transporting water and wastewater
  • reduces greenhouse gas emissions
  • reduces the need to build dams or extract water from rivers
  • decreases wastewater produced and treated at sewage plants.

Every household can cut down water use at low cost, often with costs recouped through water and energy savings within one year.

Six ways to minimise water use

  1. Reduce indoor water use by choosing water efficient showers, toilets, taps and appliances.
  2. Minimise outdoor water use by choosing plants that are appropriate for local growing conditions and by including low water use areas in the garden design through the use of indigenous plants or low water use species (see Outdoor water use).
  3. Minimise paving of outdoor areas as this increases heat radiation and water runoff from the site.
  4. Wash cars and bikes on the lawn to water grass at the same time.
  5. Sweep paths and drives instead of hosing them down.
  6. Reuse water where possible to reduce the consumption of potable water for non-potable purposes.

Go solar at home

Installing solar panels at home will allow you to generate renewable energy and reduce your electricity bills. Solar makes great sense for some buildings, but not for others. The first thing to find out is whether it will work for your building. When choosing to install solar power, it's important to consider the following:


When deciding whether to install new solar panels, keep in mind that adjoining land and dwellings may be developed in the future, or a tree or fast growing hedge may impact the effectiveness of your solar panels from overshadowing.

The ideal placement for solar panels in Melbourne is an unshaded roof pitch of 30º, facing due north. Although if this is not achievable orienting panels to the east or west are still viable options.


Minimise the visibility of a system from the street, and its impact on surrounding properties and public areas especially if your land is covered by a heritage overlay.

Roof Structure

It's important to assess the orientation of your roof, the ease of access to the installation site and the structural integrity of the roof, which all impact on the viability of installing solar panels on your roof.

Property Boundaries

Where possible avoid placing the system on or near the property boundary without first obtaining consent from the adjoining property owner(s).


Despite careful panel placement of solar panels, some overshadowing may still occur. As long as this is not greater than 20% of the surface area of your system over the warmer months, energy generation will generally still be effective


Ensure that the system is installed by a qualified professional, accredited by the Clean Energy Council.

Heritage Overlay

A heritage overlay does not necessarily prevent a solar panel installation. You will need to apply for  a planning permit if your property is covered by a heritage overlay area and the proposed solar panel system is visible from the street.In the last 12 months, ninety percent of applications for solar in heritage areas have been approved. 

Planning Permit Fee Waiver

As part of the City of Port Phillip’s commitment towards environmental sustainability the application fee typically associated with obtaining a planning permit will not be required for applications to install solar panels. For more information contact the Planning Department on 03 9209 6424.


For more information on photovoltaic and solar hot water systems please contact our Sustainable Design Officer on 9209 6303 or email  sustainabledesign@portphillip.vic.gov.au.  

Composting made easy

By composting your food scraps instead of sending them to landfill, households can significantly reduce their Climate Change footprint. About 3% of Australia’s total greenhouse gas emissions comes from organic matter rotting in landfills. That is about as much as the entire country’s aviation industry.

Step 1 - Choose a site

Place your compost heap or bin in a well-drained area that has some shade. Too much sun will dry out your compost.

Step 2 - What to compost

  • Green Ingredients: Compost needs a mixture of nitrogen rich organic materials such as fruit and vegetable peelings, and green garden vegetation such as fresh grass clippings and green leaves.
  • Brown Ingredients: Nitrogen-poor, carbon rich materials such as dry leaves, woody twigs, paper and straw.
  • Water
  • Some soil or completed compost to introduce composting micro-organisms

Step 3 - Layering

Start with a thick layer of coarse material (15cm), such as twigs or mulch, this is used for drainage. Then follow with a layered A,B,C system using the materials above A. Garden clippings and kitchen scraps, B. Dry leaves and paper (wet). C. Add water after each layer to keep the heap moist but not wet. Then repeat steps ABC. Finish with step D. Sprinkling soil or finished compost on top of food scraps will make a richer compost and help reduce odour.

Step - 4. Maintaining Your Compost 

Keep your compost well aerated to prevent foul odour or methane. Turn your compost with a garden fork on a weekly basis. Otherwise place garden stakes or pipes through the heap to allow air in.

What to add to a Compost Heap

  • Vegetable and food scraps
  • Fallen leaves (in layers)
  • Tea leaves and tea bags
  • Coffee grounds
  • Vacuum cleaner dust
  • Soft stems
  • Dead flowers
  • Old potting mix
  • Used vegetable cooking oil
  • Egg shells
  • Old newspapers (wet)
  • Grass cuttings in layers
  • Weeds
  • Sawdust (not from teated timber)
  • Wood ash
  • Human and animal hair

What not to add to a Compost Heap

  • Meat and dairy products
  • Diseased plants
  • Metals, plastic, glass
  • Animal manures (especially the droppings of cats and dogs)
  • Fat
  • Magazines
  • Large branches
  • Weeds that have seeds or underground stems
  • Bread or cake (may attract mice)
  • Bones
  • Sawdust from treated timber

Depending on the mix of ingredients the duration for the compost to turn into a rich soil can be anything from 6 weeks to 6 months.


Minimise your waste

What we consume and the packaging it comes in creates over a tonne of waste per household per year. Therefore, we need to be conscious of what we purchase and consider whether we really need it.

Minimising your waste can have significant social, economic and environmental benefits. But nothing is waste—until we throw it away. So become more aware of how we create waste and the variety of ways we can reduce, re-use and recycle. 


  • Become informed about the environmental impacts of products. If not satisfied, search for better alternatives
  • Bulk buy when possible, but don't buy more than can be used
  • Choose products with less packaging
  • Choose products with recyclable or reusable packaging
  • Carry reusable shopping bags or boxes
  • Say 'no' to unnecessary plastic bags and other packaging
  • Re-use plastic bags and all types of containers over and over again
  • Buy quality goods that will last
  • Encourage manufacturers to play their part.


  • Look for products in reusable, refillable or recyclable packaging when shopping.
  • Donate unwanted clothing, furniture and white goods to charities.
  • Enquire if goods can be repaired rather than replaced.
  • Hold a garage sale.
  • Use rechargeable batteries rather than single-use batteries and ask the local council about how to dispose of batteries properly.
  • Use retreaded tyres if they are appropriate.
  • Use glass bottles and jars, plastic bags, aluminium foil and take away food containers over and over again before recycling or disposing of them.
  • Carry lunches in a reusable container rather than disposable wrappings.
  • Re-use envelopes and use both sides of paper.


  • Separate recyclables such as glass, plastic, paper and metal from other rubbish - depending on what your local council will collect.
  • Do not put recyclables in the bin in a plastic bag.
  • Recycle kitchen and garden scraps, which can make up almost 50 percent of garbage, as compost.
  • Get involved in local school and community recycling schemes.
  • Keep potentially hazardous household waste such as motor oil, batteries, pesticides and paint out of landfill sites-council will provide information about how to dispose of them safely.
  • Encourage friends and family to get involved in recycling at home, at school and in the workplace.

It is all of our responsibilities to change the way we think and act, to tackle the problem of waste production and disposal.
