I’ve had materials telling me customers can save £180, £200, £461, £600 or even £800 a year on energy bills! Obviously from a salesmans angle, thet want to tell the customer how much they could save per year, it acts as a big selling advantage. But the credibility of the information starts to suffer when other salesmen tells the same customer different figures.
This problem contributes to the overall discussion going on at the moment about the reliability of how scientifically accurate the methods were when testing energy rated windows. What the industry needs is a reliable figure, give or take £10 or £20, to be able to say to the customer ‘this is how much you could actually save’. Until then, customers are going to be a bit sceptical.
What I would like to know is who managed to work out that one household could save £800 a year on energy bills!
>Well, the simple answer is nobody really knows, and with every window and every house being different nobody will ever know.
So, the BFRC have produced a carbon calculator to average things out.
However, with the continued silence from the BFRC about the science behind solar gain, you have to question even the BFRC's figures.

>I think this is something which will never had a definitive answer – unless they start to create equations for solar gain for all types of window dependant on their location in the house, which I doubt there will.
>heat loss cost is easy to work out in theory !1 find you window U-value2 find your heating year/ degree days ie 68.53 multiply the 2 together and hey ho that is the the amount in KWhrs that you will lose per sq metre per year . 4 multiply that by the number of sq meters of window you have 5 multiply that by the cost of energy for 1 Kwhr and bish bash bosh , that is your bill for the heat lost through the windows in your house. As for Solar gain , they cannot just make up… Read more »
>This is a bit like the political games going on right now. The government and other parties have to show their calculations to prove that their cuts and tax plans are going to work. Just as we are asking the BFRC to show their calculations to prove that their numbers also add up. But seen as though the government is involved with this, I won't be surprised to be told that it is all a money making scam.
HOWEVER! We as double glazing companies should carry on pushing WER with customers as it can provide more selling opportunities.
>DGB , the government do not understand the WER scheme, they have taken the BFRC stance , hook line and sinker. the CLG have not even scrutinised the scheme or it's science. Any one who is selling this scheme as measure of energy balance ie "gains more heat than it loses Mrs Jones" is in turn scamming their customers.
>I completely understand where your coming from. But if your an installer and your given such a simple and effective selling tool, you have to use it don't you? If it's going to win more orders and create more business, it's something the installer can't turn down.
>Many people are unaware of the existing energy rated window accreditations available in the UK. There are many benefits of installing energy efficient window products to a home or business with the key benefit been increased energy savings in some situations.
Energy rated windows has many advantages over traditional ones and is used to reduce energy bills.
