Orientation matters. Consider where you need your shade most according to your local climate, to get the most out of your shading. In all areas of Australia, you will want to try to block out the harsh western sun if possible in summer. The northern sun you will mostly want to let in in winter and block out in summer. The east may need shading in the morning, but in colder climates you’ll certainly want to allow some eastern sun in the winter months. Talk to your builder, architect or shading expert about the most energy efficient options.
Green canopies. One ideal way to allow appropriate levels of sun for the time of year is to let nature do the thinking for you and plant deciduous climbers on your pergola. This will mean you’ll have shade and sun exactly when you need them. Planting can also have a softer, more beautiful effect than hard surfaces. But remember to consider your structure and your plant – climbing plants are heavy and your pergola structure needs to be sturdy enough to cope.
Sun sails. Sails are another way to provide flexibility because they can be retracted when not required. According to Perry from Outrigger Awnings and Sails, the fabric used can be extremely hardwearing too. They use strong European fabrics that are mostly guaranteed for at least five years, but can last for 50 years, according to Perry. “They can outlast a Colorbond roof!” he says.
Rain-proof. With all structures, consider if you want to have shelter from the rain. This can be an advantage of fixed structures, clear roofing and awnings. Find out what level of rain shelter the product you’re considering provides and also ensure that it is installed correctly to be rain-proof – a fall or pitch may be required for this

Rain chains (preferably connected to dry wells or planting areas to keep water onsite) can be a handsome way to direct rainwater.
Harness the power I don’t care what erstwhile ex-Australian treasurers say, I think wind turbines are majestic. Roof turbines are lightweight, spinning vents that draw air out of the roof cavity. Powered by nature, these passive ventilation devices will whisk away excessive heat during the hotter months, as well as dampness during the cooler months. In summer, the space in your roof can get up to 50-60 degrees Celsius, so installing one of these ‘whirligigs’ will keep your power bills down and have your cooling and heating systems working efficiently. In the cooler months, up to 12 litres of moisture can gather in your roof space. Moisture from bathrooms, laundries and kitchens accumulates in the roof cavity. Without effective ventilation, the insulation will become damp and the timber frames vulnerable. Moist conditions in the roof can result in the growth of mould and timber rot.
