Insulation can improve the internal comfort of a farm, food processing, manufacturing or commercial building and eliminate up to 80 per cent of heating and cooling losses. Ceilings, floors and walls can be insulated.

Cool roofs are reflective surfaces designed to reflect more solar radiation and absorb less heat than a standard roof. Paint, sheets, tiles or shingles in white or a light colour form the reflective layer. A cool roof can make a building more comfortable in hot weather and reduce the need for cooling, which saves energy.

Both insulation and cool roofs improve staff comfort, safety and productivity, and in farm sheds, they can also improve the health and productivity of livestock. Insulation and cool roofs can be installed on new builds or retrofitted.

If you’re thinking about insulation or cool roofs for your buildings, they are a smart energy efficiency strategy, saving you money and supporting the environment.

Here are some useful resources to help you work out whether these options are right for you:

Learn from others — case studies

There are no independent local studies of insulation and cool roofs in the Australian agricultural or food processing sectors, but case studies about their use in other building types, as well as overseas examples, support their value as an energy efficiency option.

Read how an insulation manufacturer got a Green Star rating for its manufacturing facility, in this case study from the Australian Institute of Refrigeration, Air conditioning and Heating.

See this City of Melbourne study showing how cool roofs can improve summer comfort in un-conditioned sheds and warehouses but may make them colder in winter.
