CSR’s 8 star house in Western Sydney is a live demonstration of the benefits of good design. The benefits of the 8 star rating have been seen in both extreme heat and cold.

According to CSR, during testing conducted on a cold winter morning with the outside temperature at 1.2 degrees, the house never dropped below 16 degrees, despite the fact that the heating had been turned off for almost a month.

Conversely, in summer when the outside temperature topped 40 degrees, the internal temperature remained steady around 27 degrees, without air-conditioning.

Key aspects of the design include:

• connectivity to the concrete slab
• high levels of insulation and lowE double glazing
• controllable ventilation through good construction
• passive solar design
