Energy ratings for homes

Think of a building energy rating like the Energy Star Rating on your fridge, basically it tells us how energy efficient a house is and just like your fridge the more stars, the better. Now if they are currently required to be displayed on all new appliances by law, shouldn't they be shown on houses to?

Wouldn't it be great when designing your new home it came with an energy efficiency rating and depending on the rating you can make alterations at the design stage with a rubber and not later on with a sledge hammer? Building energy ratings will allow you to compare how energy efficient they are to one another and this can be a determining factor.

Great features

So what's all the fuss about?

Below are a few key features of an energy efficient home.

All about design

So when we talk about an energy efficient building we aren't talking about adding solar panels and LED's, we are talking purely about the design. Our aim is to create an energy efficient design the rest we can just add on later, if we need to that is.

Compare the market

We compared the average 3 Star home found across NSW to the exact same home but with a 10 Star energy rating and found that a 10 Star home is 25x more energy efficient than the majority of homes already built around the NSW.

A bridge between the outdoors and indoors

What we do is invite the outside in, we allow your home to be cooled by the breeze and be warmed by the sun. All our plans are specifically designed for your site and designed to work with it and all the natural elements. Who said going green was more expensive?

No need for mechanical heating and cooling

In theory having a 10 Star rated home means that whether its 40 degrees outside or minus 4, inside will stay at a relatively comfortable temperature without the need for an air-conditioned or heater.

Reduce your carbon footprint

Heating and cooling accounts for 40% of the energy used in an Australian home, making it by far the largest expenditure of energy in our homes. Now what if we could eliminate heating and cooling? This will nearly cut in half the average energy used by an Australian home and really cut down on the greenhouse gas emissions.

A smart investment

A recent Australian study has found that, on average a one star improvement in the overall energy rating of a home translates to a 3% rise in the market value of your home.

Now for all the nitty gritty

So now that we have caught your attention, click on the tabs below and you can find out more information relating to energy ratings, the process and all its benefits.

Think of the building energy rating like the Energy Star Rating on your fridge, basically it tells us how energy efficient a building is and like your fridge the more stars the better. It assess how much energy is used to heat and cool your home and keep it comfortable all year round.

It does this by running your home through a computer simulator and assessing each individual room for every hour of everyday for an entire year and at the end you receive a star rating out of 10 Stars that lets you know how well it performs and highlights any problem areas that need to be addressed.

By having an energy assessor work closely with you during the design phase of your new home it will give you an in depth look into how comfortable it will be to live in and changes made at this point will be a lot easier than later down the track.

The best way to think of it is an investment that will last the life of your home, if you are spending all that money building you really want to make sure that your home is not just architecturally beautiful but energy efficient as well. Having an assessment done will save you money on your energy bills, create a home that naturally stays cool in summer and warm in winter and you will be doing your part for the environment.

From May 2011 t’s a requirement of the National Construction Code (NCC) that all new buildings and extensions are energy efficient. If you’re building a new house, town house, apartment complex or if you’re planning an extension of your current home, then you’ll need a certificate that says it complies with the Code. This is where the Nationwide House Energy Rating Scheme (NatHERS) comes in and is enforced in every state other than New South Wales where the BASIX supersedes this.

If you’re just after a non-obligated free quote, all we need to see is your project’s site plan, floor plans and elevations and we will get back to you as soon as possible.

Once we have a copy of your plans and all the necessary information we run your home through a computer simulation program that will calculate air temperature of each individual room for every hour of everyday for an entire year. This will give us an in depth look into how well your home performs and pin points any problem areas that need to be addressed.

To give you an example, by simple trialing window sizes in a specific room we are able to come up with the perfect size window which will let just enough sun in in summer so that it still stays cool all day long and plenty of sun in during winter to keep that room warm.

It’s a delicate balancing act but by the end of it you are left with a home that will be comfortable to live in all year round and the money you save on your heating and cooling bills you can use for other things, like a big TV!

Generally we have a fast turnaround turnaround usually under a week for individual homes and one to two weeks for multi-residential developments once we have all the required information. This may also vary depending on our current workload and the complexity of your design.

Although saying this we understand that sometimes you may need a specific job completed before a certain deadline, we are happy to work with you to make this happen which may incur an additional fee.

Because we do not physically need to come to your site we are able to work on projects all over Australia. You can find a list of all the required information above.

New South Wales introduced the Building Sustainability Index (BASIX) in 2004, with the aim of reducing a dwellings use of water, increasing the energy efficiency and reducing greenhouse gas emissions. A BASIX Certificate is required by the Department of Planning and Infrastructure when submitting a Development Application to your local government council.

10 Star is a BASIX accredited certifier, the process follows the NatHERS assessment method as well as entering extensive data into the BASIX online index.

Climate change is arguably the greatest challenge faced by humanity today and according to the ‘Department of the Environment website’, Australian households are directly responsible for about one-fifth of Australia’s greenhouse gas emissions.

The average household’s energy use generates over 7 tons of greenhouse gas emissions from its premises. Heating and cooling accounts for 40% of this energy use, making it the largest energy user in the average Australian home.

Now what if we could eliminate heating and cooling from a home? This will nearly cut in half the average energy used by an Australian home and really cut down on the greenhouse gas emissions produced.

We are proud to announce that we are a member and accredited by the Building Designers Association Victoria (BDAV) as a Residential Thermal Performance Assessor and accredited BASIX certifier.

Being accredited means that our qualifications are recognised and that each year we must continually develop our knowledge in sustainable design and follow a strict code of conduct and ensure that we always meet industry standards and regulations as well as the expectations of our clients.

10 Star is a small business that limits the amount of work we take on to ensure that each job is thoroughly and properly looked after. We are fully certified by NatHERS and BDAV accredited members so you can be confident that you are speaking to someone that is knowledgeable in this area and can give you the very best result.

We also have a background in design which we specialise in sustainable design and have experience and the systems to deliver exceptional expertise for your project and we can guarantee to always find the perfect building solution by providing quality, reliable consulting advice at a competitive price.
