COMPARE THE EFFECT OF ORIENTATION ON THE THERMAL PERFORMANCE
WHEN DESIGNING A NEW SINGLE STOREY THREE BEDROOM HOUSE
With this simple test you can select the main direction (orientation) that the proposed living areas (e.g. Lounge, Family room or Rumpus) will face by clicking on the orientation buttons in the panel below.
Notice how the overall thermal performance of the house varies as the orientation of the living areas is changed. Compare the results with the proposed design for your new house or even your existing home.
The follow parameters were used to model the house in BERS Pro software:
Climate zone: Sydney BCA 5 & NatHERS 56 (see note 2)
Insulation level: as specified in note 3 below
Windows and glass: Single clear glass in aluminium frames
Shading: 450 eaves with fascia and gutter or 600mm eaves overall

1. Building construction: Brick veneer on concrete slab used to calculate the results on this page.
2. Climate zone explanation: BCA (Building Code of Australia) is the national building standard. NatHERS (Nationwide House Energy Rating Scheme) is the Commonwealth Government body regulating the thermal performance standards for housing.
3. Insulation R1.5 in the walls and R2.5 in the ceiling space.
4. External Shading: Eaves shading only used to calculate the results on this page. The addition of a shade pergola or external blinds can significantly improve the summer thermal performance.
