Deciduous trees and grouped vegetation planted along North and North-West boundaries to block excessive sun in summer and afternoons, but because the trees are deciduous, they will allow sunlight through during winter.

Living spaces facing North to maximise daytime sunlight.

SITING, ORIENTATION & DESIGN CHOICES

Construction

Brick cavity walls were chosen as the external wall system because they not only act as a thermal mass but also are structurally long lasting and require minimal maintenance.

Since the walls make up a large portion of the home, and is also exposed to the sun, insulation value for the wall batts were increased to R2.50 for better performance.

Concrete roof tiles were also selected for similar reasons. Due to the importance of the ceiling in a building’s energy efficiency performance, it was very important to choose a material that was not only durable but also provided great insulation values as the roof is the part of the building which is exposed to the sun the most. Roof sarking was also added to help reflect radiant heat and help to maintain a stable temperature within the home.

Orientation

Orientation is one of the main factors, which influences energy efficiency. The original ABSA house floor plan has been mirrored and flipped to ensure the most energy efficient outcome.

The home has been sited with living spaces to the North, and bedrooms to the South to maximise daytime sunlight to the living areas, and reduce overheating in the bedrooms. The garage has been moved to the Western side of the home to help block out excessive heat transfer into the home and also to act as shading for the outdoor room.

The largest area of windows (approximately 10sqm) in the home were designed to face North with double-­‐glazing to allow for maximum sunlight but minimise excessive heat transfer into the home.

Energy Efficiency

Due to the materials chosen, orientation of the home and other energy saving measures taken, the home has reached a star rating of 6 stars (55 points) in the FirstRate program.

FirstRate4 Report – House Energy Rating 5 KEY CHANGES:

1. Change ceiling insulation R value to 3.50, add Sarking (R=1.0)

2. Change ceiling type to Attic -­‐ Vented

3. Change wall insulation R value to 2.50

4. Add carpet as 80% floor cover

5. Change wall type to Brick Cavity

Service Choices, Innovations & Sustainability Measures

Evacuated Tubes Hot Water System

Although this system is widely used in Asia, it is still quiet costly to install in Australia. However, the evacuated tubes system is more efficient in comparison to solar water heating, especially in cooler and cloudier climates (like Melbourne). This system is also preferable when limited roof space is available for solar panels.

The evacuated tube solar system is made of hollow double glazed glass tubes, copper piping (heat pipe). The air between the tubes is pumped out, while the outside of the tubes is heated, creating a vacuum. This effect creates excellent insulation, trapping the heat inside the tube, making solar hot water evacuated tubes very efficient.

In order to heat water, an absorber coating inside the tube system absorbs solar radiation from the sun; the water is then moved through the collector to heat and then moved on to the hot water storage tank.

Evacuated Tubes Hot Water Systems are usually able to heat larger quantities of water at a faster rate in comparison to solar panel heating.

Slimline Wet System Rainwater Tank

Tankworks Website has a “Size-­‐a-­‐Lator” program, which calculates the size of the tank required to reach your desired Tank Capacity. Since a minimum 5000L is required to receive the $1000-­‐ 1500 cash back, the image to the left shows the minimum sized tank required.

Minimum height of the tank = 2.02m. Minimum length of the tank = 3.00m. Minimum width of the tank = 0.9m

The size of this tank will provide a tank capacity of 5103 Litres, which is good for: • 850 toilet flushes • 5 hours of hand watering • 63 washing machine loads

This size of this tank would fit perfectly next the garage and will also fit under the 1m wide eave.

Environexus Energy Management

Environexus is a retrofit energy management system, which turns existing power points into Smart Energy outlets. Energy throughout the whole home can be controlled through a smart phone or smart device anywhere in the world, similar to that of a C-­‐BUS system.

However, because the Environexus system is retrofit, the cost of installation is a lot cheaper than a wired C-­‐BUS system.

On the homeowner’s smart tablet (Apple or Android), they’re able to access reports about their current energy usage, energy usage per device and the consumption trends per appliance. This information can be shown in hours, days, weeks, months or years, and is also able to calculate upcoming energy bills using previous trends, and the home’s Carbon Footprint.
