The Scorecard is designed to assess how your house performs in both hot and cold weather. The Scorecard certificate provides recommendations to help you improve your house to deal with heatwaves and cold spells.

Hot weather

The Scorecard certificate includes a hot weather rating. An example is shown below. A house with a 'very easy' (4-5 blue squares) hot-weather rating will stay cool for longer, even if there is no air conditioning available.

This section shows how you can keep your house cool during hot weather, even if the power goes out. The rating can help you prepare your home for hot weather.

Cold weather

The Scorecard certificate does not provide a specific cold weather rating. However, in cooler climates like that of Melbourne, the rating given for your home's building shell tells you how your house performs in the cold without heating.

Your building’s shell rating is based on any gaps and cracks in your exterior walls, insulation, the materials your walls, floors and ceiling are made from, and the size, placement and covering of your windows.

Improving your building shell rating will help keep your house warmer in winter without using the heater as much.

What hot and cold weather have in common

The most important factor in hot and cold weather is where you want the heat to stay. In hot weather, that's outside the house; in winter, inside.

You can improve the way your house performs in both the cold and the heat by improving the weather tightness of your building shell. Some ways of doing that are:

  • upgrading insulation
  • sealing gaps and cracks
  • improving your window glazing or windows' external or internal coverings (such as curtains).

A Scorecard assessment will tell you which parts of your building shell could most benefit from improvements, and your accredited assessor will discuss with you what sorts of upgrades would best suit your home. If you make those improvements, you'll stay warmer in winter and cooler in summer without having to crank up the heater or the air conditioner.
