Short for the Nationwide House Energy Rating Scheme, NatHERS uses a 10-star rating system which is able to easily access the thermal performance of buildings within Australia. Though a NatHERS certification is required for all new developments with multiple dwellings, it is essential for all residents to obtain an assessment to be able to easily evaluate the thermal assessment of their development.

At Certified Energy, our years of experience distinguishes us from our competitors. We work with each client separately, to ensure that each individual project thrives in terms of cost, efficiency and the preservation of design concepts.

We strive to minimize your costs whilst maximizing the sustainability of your future home.

Why is NatHERS assessment required?

NatHERS as outlined above is the Nationwide House Energy Rating Scheme which is able to evaluate the thermal performance of any dwelling. Though this may seem irrelevant and unnecessary when outlining the overall performance of the building, it is a necessity to get a NatHERS assessment in order to ensure a sustainable future for our environment.

Not only this, but NatHERS is essential when obtaining a BASIX assessment. BASIX is a NSW Government initiative striving to improve the environmental sustainability. It comprises of three factors: water, thermal and energy. The thermal component of BASIX can be easily completed through a NatHERS assessment with its thorough, accurate and flexible approach to addressing thermal performance.

Thus, a NatHERS assessment is required not only to contribute towards a sustainable future for the environment but also as a necessity under the BASIX initiative led by the NSW Government.

What does a NatHERS assessment include?

A NatHERS assessment can be obtained by a specialised company that has NatHERS Accredited Software which can be used to determine the thermal efficiency of your home. Within the assessment, each resident will be provided a copy of the key design features and the building materials and the scope used to generate the dwelling’s star rating.

The star rating, also known as the Energy or Thermal Efficiency star rating, is an accurate indicator of the level of heating or cooling your building requires to not only make you feel comfortable, but to ensure that it doesn’t have a detrimental impact on the environment. By following the recommendations and guidelines that will be included in your report, you will also be on the path of having lower energy expenses, by using the appropriate amount of electricity.

How does Certified Energy do it differently?

At Certified Energy, there are two main certification solutions that will help you achieve the lowest cost with the highest efficiency rating. These include the essential solutions (House Energy Rating Scheme, Elemental Provision) or alternative solutions (Verification Using a Reference Building and State Specific Energy Protocols).

In order to give you the best catered advice as per your personal needs, Certified Energy will guide you through the various approval pathways that will help your project achieve energy efficiency and environmental sustainability.

How to Reduce HVAC Energy Consumption at Home?

Heating and cooling account for more than 50% of home energy consumption. If you are paying a lot in the name of energy bills, your HVAC system is most likely the primary cause. It is vital to cut down on the energy consumption of utilities to save money (and energy). Energy companies such as American Power and Gas, suggest consumers and homeowners pay special attention to their HVAC system. as heating and cooling cost make up about 40% of your energy bills.

It may also be wise to consider switching to a system that operates on solar or other forms of renewable energy––Providing if it can be afforded.

Here are some ways you can reduce HVAC energy consumption:

Programmable Thermostat to The Rescue

HVAC system design can be made to consume less energy with the help of programmable thermostats.

The DOE recommends reducing room temperature to 15 degrees in winters when you are not home for 8-10 hours. Similarly, they suggest increasing the temperature by around 15 degrees in summers when you are not going to be home for half the day. This will help you save about 15% more energy annually.

The benefit that programmable thermostat gives you is that you won’t have to manually adjust the temperature every day. You can simply program it to change the temperature and save energy. It also has the added plus of operating on a timer so you don’t have to worry about leaving it on throughout the day.

Maintain The Coils Of Your AC Unit

The outdoor unit of the AC can allow dirt and debris to pass through it and gather around the coils and reduce the efficiency of the AC, as a result the unit consumes more energy to keep the room cool.

Keep your outdoor unit clean from dirt, fallen leaves, and other debris to make it work perfectly. If you believe that your outdoor unit needs cleaning, shut it off and use a vacuum to pull out all the dirt.

Inspect Air Filters 

Air filters need special attention as they can get blocked due to dirt and debris. They need to be replaced every season as damaged filters put extra pressure on the unit causing energy to be wasted.

Other than this, you should also replace the filters every now and then. This is not a very tough job and you can do it on your own.

Here’s how to do it:

  • Remove the filter and check for debris stuck in the filters.
  • Keep the filters under light to see if it’s able to pass through. If it doesn’t then you will have to wash the filters.
  • Clean the filters with a toothbrush, or another such tool first.
  • Put the filters in soapy water for a few hours, dry and see if the light passes again. If it does then you can re-apply those, otherwise, you may have to change the air filters.

The average life expectancy of air filters is about 2 to 3 months if they aren’t maintained. Otherwise, they can easily run for a year.

Out With The Old, In With The New

HVAC systems can be costly but if you have been using one for more than 10 years now then it’s time to replace it with a modern and an energy efficient HVAC system.

AC Coils of HVAC systems require regular cleanup

A Clean Way to Cool Down

You can also consult with your energy provider regarding making the switch to renewable energy services. You can also look into energy storage systems such as Tesla’s solar panels that can drastically cut your power bill and provide clean sustainable energy for your home.

The Verdict

Around 48% of US home energy consumption is directly attributable to HVAC use and heating or cooling. These are some of the most efficient ways which you can reduce the amount of energy consumed by your HVAC system.
