Congratulations on being the owner of a heritage place or living in a heritage area.
The National Trust and the City of Greater Geelong would like to help you retain the heritage value of your property whilst implementing energy saving measures. This leaflet is a guide to enhancing the heritage and sustainability of your place.
Heritage places reflect the diversity of our community. They enrich people’s lives and provide tangible connections to the past and lived experiences. Importantly, the conservation of heritage places can have environmental, social and economic sustainability benefits.
Retain rather than remove
Can keeping heritage buildings make a difference to the environment? If you think of the energy that has also been consumed in producing the building, the answer is yes. Known as embodied energy, in existing building stock it is equivalent to 10 years of the total energy consumption for the nation.*
Once a building reaches over 50 years in age, recurring embodied energy savings increase dramatically. It can therefore be better for the environment to retain, reuse and adapt heritage buildings rather than demolish them. This is because the need for new construction materials is minimized, especially if designed carefully.

Solar Panels require careful consideration about their placement to ensure no heritage impacts on the character of the building. Where possible, rear roof faces are the best heritage outcome.
North-facing Edwardian dwelling with solar panels installed on the side roof face.
Although north roof faces are most ideal, installations on east or west roof faces are possible and more ideal as they have far less heritage impact on the character of the front portion of north-facing buildings.
In situations where alternative less visible locations on the roof might not be possible, installations on garages and other outbuildings might be an option.
Solar panels installed on the rear garage instead of the front roof face of the dwelling.
Freestanding panels (below) might be an alternative where solar panel installations on the roof of a significant dwelling will have a visual impact or where the panels might damage significant roof cladding.
This farm outbuilding (below) was used for solar panel installation, allowing the significant dwelling to remain unencumbered of panels on the north roof face that is highly visible from the road.
Repair rather than replace
Regular maintenance can help prolong the need to replace materials as well as improve energy efficiency. Maintenance might include repairing leaking roofs, taps, damaged windows, doors and seals and unblocking vent openings.
Retrofit rather than consume
Wanting to reduce your energy bills?
Installing energy measures may be possible even with heritage buildings. These measures might include installing:
Secondary glazing to heritage windows.
Blinds, awnings or window hoods (depending on the location and heritage significance of the building).
Reconstructing missing verandahs, porches or window hoods.
New heating systems.
More energy efficient lighting, taps and shower heads.
Solar panels and rainwater tanks (its best for them not to be located at the front).
The introduced window in the west-facing front gable of this Edwardian dwelling has been replaced with an appropriate paired, timber framed double hung window and equally importantly, a window hood has been reinstated. This has enhanced the character of the dwelling as well as provided some shade.
Do you need a planning permit to retrofit?
Under the heritage overlay in the Greater Geelong Planning Scheme, a planning permit is required to carry out works including:
A solar energy facility attached to a building that primarily services the land on which it is situated if the services are visible from a street (other than a lane) or public park.
A rainwater tank if the rainwater tank is visible from a street (other than a lane) or public park.
Need more advice?
The City of Greater Geelong’s Statutory Planning Department can assist you with any questions about your energy saving ideas and whether you need a planning permit. The Council also has a Heritage Advisory Service where you can seek advice about greening your heritage building. Call the Statutory Planning Department on ph. 5272 4456.
