Incorporating Passive Design

At Central Avenue Homes we try to use passive design principles so our clients benefit from comfortable environment. This assists with lower heating and cooling costs. In this post we discuss what Passive Design is. The key principles and how they can be used in your new home design.

We encourage our clients to explore this topic further by visiting Your Home.  An Australia government website that promotes environmentally sustainable homes. Below is an excerpt from Your Home.

Passive Design

Passive design takes advantage of the climate to maintain a comfortable temperature range in the home, that reduces or eliminates the need for auxiliary heating or cooling, which accounts for about 40% (or much more in some climates) of energy use in the average Australian home.

The importance of passive design cannot be overstated. Paying attention to the principles of good passive design suitable for your climate effectively ‘locks in’ thermal comfort, low heating and cooling bills, and reduced greenhouse gas emissions for the life span of your home.

Heating and cooling

Passive design utilises heating with the sun and cooling with the breezes. It can be achieved by

  • Placing your building on the site to take advantage of the sun and cooling breezes
  • Taking into consideration the building materials including roof, walls, windows and floors of a home.

A well designed home, using the right products will minimise the loss of warmth and assist with cooling.

The cheapest time to achieve this is when designing and building your home. However, renovations to an existing home may also upgrade thermal comfort. Even small upgrades to the home can provide significant improvements. Regardless, whether you’re buying a new home or apartment, assess its possibility for thermal comfort. And more importantly, the cost to upgrade the home to suit the climate, and if it is possible.

Best results

For best results, the owner can work with the daily and seasonal climate. Such as opening or closing windows doors and window treatments to suit the current climate. For example, If it’s hot, close the windows, doors and window treatments. If there’s a cool breeze, open the doors and windows. By doing these small things will help keep your home cooler in the summer and warmer in the winter. Because we can have very hot summers and cooler winters, the design of your home is extremely important. Just by making sure your windows face the best direction for the sea breeze and afternoon sun will make a big difference.

Some things to consider that will help this work will vary with the:-

  • Direction your home faces.
  • Size of windows and glass doors
  • Colour of your roof
  • Insulation in the walls as well as the roof
  • Placement of doors and windows to allow a cool breeze
  • Window treatments to block out the afternoon sun
  • Roller shutters
