Out of the many ways to save money on your house, passive designs are the only aspect that will give you a long term benefit. Irrespective of what you think about the environment and climatic changes, it definitely affects the energy consumption in the houses.
So in the bigger picture, sustainability is not just a fad, but a choice of living where you can save both financially and contribute to the environment.
The initial cost in installing such passive measures will soon be overcome by what you profit from it. It would save you thousands of dollars as bills, but it would also be a highly sought after feature in future homes when you are looking to sell.
Apart from all the talk about passive design, let us start from the basics here.
What is Passive design?
The passive design takes advantage of its surroundings and microclimate to reduce energy consumption in the house. It could reduce the requirement of heating or cooling immensely. In an average Australian home, this contributes to around 40% of the energy use. Choose the right Brisbane builder for your home.
The only way to achieve this is to work with the environment rather than to work against it. A thoughtful passive house design uses the natural resources of light and heat, with the orientation and other design elements.
Many strategies could contribute to an effective passive design. Take a look here at a few.
1. Design for the Climate
There are many climatic zones in Australia with its own characteristics. The first thing to do is to identify your zone and go for the appropriate design objectives for the location. You can ask your designer and builder to use resources like the Nationwide House Energy Rating Scheme (NatHERS) for further help.
Orientation means how your house is placed to take advantage of the climatic features of your site. For instance, if you face the rooms to the north, then it will allow maximum exposure to both sun and heat. This will also reduce the need for auxiliary heating and cooling. You can also place rooms like bedrooms in the south, where you will be more comfortable in darker rooms. Zoning such rooms together would be advantageous both design and function wise. Finding the right finance broker can literally save you tens of thousands.
3. Cross Ventilation
Designing with proper openings that allow cross ventilation into the house would make it cooler. The wind alone would be enough to create an air flow in the house and could often replace the need for air conditioning. It also keeps the air fresh inside the rooms, making it a healthier and cheaper alternative to electrically powered coolers.

4. Solar Power
Solar energy is one of the renewable energy that is always there at disposal. Installing a solar panel could be beneficial in many ways. You could get the power for water heating, pool heating and even for electricity in your home. You might not even have to cover the entire roof, just a part of it.
North facing roof slopes without any overshadowing from trees or neighbouring houses are an ideal position to place the solar panels. Choose the right Brisbane builder for your home.
During summer months, sufficient shade features could keep the heat away to a large extent. It could be a sun with sunshades above doors and windows, awning, eaves, shutters, pergolas and even roof gardens and other plantings. All these will reduce the direct heat. However, a bad design could also prevent winter sun. The angles of such shades have to be carefully calculated to suit your location and taking into account the climate and orientation.

6. Sealing the Home
Air leaking could cause about 15 to 20 % of heat loss from buildings. Sealing your home is the simplest way to prevent this especially in winter months. But again, you need to take measures to reduce the condensation and control the quality of the air inside the rooms too.

Insulation is one of the best ways to stop heat flow in and out. This keeps your house cool in summer and warm in winter. A well-insulated house also helps with weather and soundproofing your house, and It could contribute more than sufficient to cut the costs of heating and cooling bills throughout the year.
Depending on the location and design, there are many types of insulations to choose from for the house. It is also important to install them correctly to get the intended effect. If not, it could even be a reason for extra energy loss. Choosing the right building designer is important as it can make or break your project.
8. Thermal Mass
The ability of a material to absorb and store heat is called its thermal mass. The materials used in the construction does contribute a great deal to this. For materials like concrete, bricks and tiles, a lot of heat energy is required to penetrate its high density to change the temperature. These have high thermal mass as opposed to materials like timber.
Using such materials with high thermal mass throughout the house can cut the costs of heating and cooling. For it to be entirely effective and not work adversely, it has to be integrated well with other passive design techniques appropriate for the climate.
9. Glazing and Skylights
Window gazing brings more light and views into a room but is also a major source for unwanted heat loss in winter and gain in summer. Glazings could bring in 87% more heat gain and 40% of heat loss. The only way to work around this is by choosing the right specification of glazing for your region. Get in touch as one of our friendly team members will get back to you within 48 hours.
Skylights are a similar feature that could have the same effect on energy. Though it brings in more light than the vertical windows itself, factors have to be considered while choosing its size and material to avoid glare and to increase the efficiency.
