Avoiding Mistakes on Your Path to a 6-Star Energy Rating

Have you ever had a sinking feeling upon receiving your energy bill? Having a 6 star energy rating for your house could be the best course of action. Imagine living in a home that minimises its impact on the environment while being cool in the summer and cosy in the winter. Sounds ideal, doesn't it? Though there may be unexpected difficulties on the road to an energy-efficient home. Sometimes, your regular activities can turn out to be a big mistake and stop your home from being sustainable.

Well, don't worry. This article will show you the most frequent blunders people commonly make so you may avoid them and create your ideal, and super-efficient house. From talking about the slipups to suggesting solutions for a better energy rating this write up will work as a guide. So, let's take one energy-saving action at a time to make your goal of a 6-star rated house a reality!

Underestimating the importance of insulation

Proper insulation helps trap cool air inside during hot weather and warm air inside during cold weather. This means your heating and cooling systems don't have to work as hard, saving you money on energy bills.

Insulation comes in different thicknesses, measured by an R-value, and the higher the R-value, the better it is at blocking heat flow. The common mistake we often make is using too little insulation or one with a low R-value for our climate. So, it can't keep the house warm properly and ultimately costs you more energy bills. Also, another blunder often occurs while setting insulation. Sometimes, insulation gets forgotten in certain areas, creating weak points in your thermal shield. Places like windows, doors, and where the floor meets the ceiling are often culprits, so it is necessary to ensure a good insulation system in these areas.

Ignoring window design and orientation

Windows are great for bringing in sunshine and fresh air, but they can also be sneaky energy culprits. We often ignore our windows and how it will be located but the size and place of your windows can directly influence how much energy your home uses.

Think of it like this: the south faces the sun in Australia, so large windows on that side will let in a lot of heat during summer. This means your air conditioner will have to work extra hard to keep things cool. On the other hand, north-facing windows capture beautiful natural light without the scorching heat. So, when planning your windows, aim for more on the north side and keep them smaller on the east and west sides.

Not considering the home's size and layout

While an extensive dream home might sound tempting, size can present a challenge when aiming for a 6 star during energy rating assessment. Th error arrives when we think no matter the size or design of the house we will need same power to run it smoothly. But the truth is Bigger houses naturally require more energy to heat and cool. The key is to embrace smart design principles.

In this case, minimising the number of external walls helps. A compact design with a smaller footprint reduces the overall area that needs heating or cooling. Additionally, consider clever positioning of rooms. Placing living areas that generate more heat (like kitchens) next to cooler zones (bedrooms) can create a natural thermal flow within your home.

Failing to seal air leaks

Imagine your house is like a balloon. Tiny holes can let the cool or warm air escape, making it impossible to expand it properly. The same goes for your home's energy efficiency. Air leaks, even small ones, can significantly impact how much energy you use.

These leaks act like hidden energy thieves, allowing precious cool air to whoosh out in summer and warm air to disappear in winter. This forces your HVAC system to work overtime to keep your room at a desired temperature, and that leads to higher energy bills. So, it will be your mistake if you let these sneaky leaks go unnoticed. Common areas of air leaks include windows, doors, vents, and even places where pipes and electrical wires enter your house. By sealing these leaks, you're essentially plugging the holes in your energy balloon, keeping your home comfortable and saving money on your bills.

Using low-efficiency appliances

Did you know your fridge or washing machine can be major energy consumers? Our old refrigerator or the big-sized electric oven might be giving you a long-term service but silently causing more bills and stopping you from achieving a standard energy rating. That's why looking for the Energy Star label is key.

Think of the Energy Star rating as a scorecard for appliance efficiency. The higher the stars, the less energy the appliance uses. Replace the higher-bill consuming appliances with modern energy-efficient ones. By choosing high-efficiency models for things like heating, cooling, hot water, and lighting, you'll be saving money on your bills and helping the environment at the same time.

Neglecting passive design principles

We all dream for a home that stays cool in summer and cosy in winter without constantly running the air conditioner or heater. We commonly do the mistake by considering it impossible. With the magic of passive design its now possible! It's all about using nature's free resources to create a comfortable living environment.

Passive design techniques like natural ventilation and shading can significantly reduce your reliance on mechanical heating and cooling systems. For example, strategically placed windows and vents can help draw in cool breezes during hot weather. Similarly, planting trees or using awnings can shade your house from the harsh summer sun, keeping the inside cooler naturally. By embracing these elements, you'll be harnessing nature's power to create a comfortable and energy-efficient home.


To sum up, a 6 star energy rating for your home isn't just good for the environment; it's good for you, too! It will provide you with a comfortable living space that ensures comfort no matter the season, all while saving you money on bills. Remember, seeking professional guidance from architects, builders, and certified energy rating companies can make all the difference. With a bit of planning and the right team by your side, your energy-efficient home can become a reality!
