Cool in Hot Days: Reducing Heat Gain at Home

Home Heat Gain in PerthYou don’t always have to crank up the air conditioner to keep cool during hot summer days. The best thing you can do is to reduce solar heat gain by keeping the sunlight out. The key is to block the light before it enters and penetrates your house through doors and windows. Insulation, reflective barriers and shading all do a wonderful job in blocking the heat.

Trees and Shrubs

Well-positioned trees and shrubs can effectively block sunlight, which can also lower the temperature in the surrounding areas. Deciduous trees are the best choice, as they can provide shade in the summer and allow heat to pass through during colder months. Shrubs, on the other hand, can block heat gain in the lower portion of the wall while also serving as a windbreak in the winter.

Curtains and Shutters

Drapes and curtains, especially those with a light colour, can reflect much of the sun’s rays away from your home. Many residents in Perth use roller shutters, as it can reduce heat gain by up to 90% while preventing heat loss during colder seasons. The best thing about them is that they have thermal characteristics that can lower energy consumption and greenhouse gas emissions.

Insulation

While insulation and weather stripping are known to be beneficial during winter, they can also keep your home cool on hot days. Insulating the attic floor, for instance, can keep the heat from radiating or going down into the house. Weather-stripping doors and windows, on the other hand, can prevent warmer outdoor air from going into your home.

Reflective Barriers

When it comes to keeping sunlight away, your house colour matters. A dark exterior, for instance, can absorb up to 90% of radiant energy from the sun, with the absorbed energy leading to heat gain. Light coloured exterior, however, can effectively reflect most of the heat away from your house. You can also install radiant barriers to help reflect incoming heat.
