Should Victoria scrap 6 star ratings?

Carpenter on a roof frameThe Victorian government is looking at scrapping it’s 6 Star energy rating system. The Age  is reporting that the  removal of the 6-star standard in Victoria is part of a bid to cut government red tape by 25 per cent by July 2014.

Rather than a reduction in red tape I would argue that the Victorian government is reacting to a ground swell of unhappy people who are having to pay for their part in global warming. Their rancour stems from  the unsettled nature of climate science and the very unfair way the cost is being forced on all Australians.

The 6 star energy rating system has been adopted across most of Australia. Homes are modelled using thermal performance software to assess their efficiency. The higher the efficiency the more stars they achieve. A 6 star home will stay comfortable for longer periods in a year and require less energy to heat and cool. A 6 star home will be cheaper to run than it’s five star equivalent, all of which are pretty good outcomes.

Appliance energy rating tagThere is not a great deal of red tape involved in an energy rating. The rating is done as part of obtaining a building permit and is undertaken by private thermal assessors. They are as easy to obtain as a soil report or a house valuation. The government involves itself in monitoring building permits and in licensing hierarchy of the raters, but otherwise is quite separate from the process. The Victorian government has added the additional impost of  solar hot water or rain tanks for the people of this sate alone.

I believe people are fed up with paying for global warming and are wildly unsatisfied that a need even exists. When the populace turn off for earth hour it is typically a 42 inch flat screen that is being powered down. We mean well but we are being disingenuous. I am yet to find a home owner who has been happy to pay the increased cost of LED lights over downlights.

The Age report  touts an average cost of $ 5000 to go from a 5 star to a 6 star rating . Whilst I think this figure is exaggerated, equally silly was this statement from Rodger Hills – Acting CEO for ABSA the peak energy rater body in Australia.

“6-star can be achieved with little or no added cost and the amount you can save on your energy bills is significant,”

Utility cost have been risingCan I suggest you get your double glazing  where Rodger shops! Clearly the figure lies between these extremes and it is going to take a long time to recover any additional cost with typical energy bills of $1800 a year and savings of maybe $ 400. (based on saving an additional 10,000Mj a year with a 6 star home)

Brian Welch of the Master Builders Association of Victoria says the previous five-star model is more appropriate.

“When you consider the Australian climate, the 5 star was a sensible balance in finding what is a reasonable level for consumer protection in this regard, of energy efficiency,” he told ABC local radio.

We have had these energy rating schemes for some time now but the benefits have been invisible in a period of hyper inflated energy prices. As the cost of electricity and gas  rise 30 %, year on year, it is hard to see if we are making any headway.

We have long argued  that homes need to be thermally designed from the outset. A significant  problem exists with mandatory energy rating schemes where homes are poorly designed initially. The sound idea of North facing solar access is impractical on a west facing suburban block.  The principals of summer shading are lost on  mock Georgian built without eaves. The measures to achieve a six star rating in these cases are costly and impractical.

All of this is also happening in a period when the world has continued to cool for more than fifteen years. It will be hard to recruit the next generation of green believers from teenagers who have no evidence of global warming during the entire span of their lives. It is also happening  before we have discovered the true cost of the ill-advised carbon tax people.

We want to be green, but we just dont want to pay!

    If it wasn’t for the 6 stars & few other quirky items I would say you were writing about the US. Wow 30% increase year over year – is that because of the Carbon Credit schemes, or… 

    I think this statement sums it up best – We have long argued that homes need to be thermally designed from the outset. A significant problem exists with mandatory energy rating schemes where homes are poorly designed initially.

    Here we say like to say it is easier & cheaper to build it green from the start. As for the 5000 to no cost - we see the same issues here & generally the truth is somewhere in the middle. A big factor is also what the builder considers their base package. For me I would have generally saved money by only building to the newest codes, whereas others generally pay out the a$$ because they try to play the we didn’t know card.

    One other major factor (which is what I do now) is if you can find a good energy modeler that knows building, we can help you meet the requirements without going overboard. 

    As for global warming, love how I have now lived through an ice age is coming, to this… I got to wonder whats next?

      You point is well made, model the changes when it is a home on paper and you can potential save some serious money, wether they are green backs or $AUD!

    No! 6 star rating must be implemented not to be wasted.

    No, I don’t think so. 6 Stars makes perfect sense and very valuable just to be thrown out of the garbage!
