AN ABERGAVENNY man who transformed his home with green features will show the public how they can do the same.

John Cranna, a self-employed structural engineer, will invite people into the Lower Monk Street property, which he bought in 2004.

Since then, he has reduced his domestic carbon emissions by 68%, installing loft, floor and wall insulation, low energy lighting and solar panels in the roof, spending around £15,000 of his own money.

Mr Cranna decided to do this as a long-term investment, as he did not want to spend big amounts on energy bills.

The 'Superhome', only one of two in Wales, was visited by Wales' Minister for Environment, Sustainability and Housing, Jane Davidson, last week, who said the home was an example to others of how to make Welsh homes more efficient.

"As John has proven, by installing insulation, upgrading to an energy efficient boiler, and switching to low energy light bulbs, we can make quite dramatic changes to the energy efficiency of our homes, whilst at the same time cutting down on heating bills," Ms Davidson said.

WWF Cymru, who took the minister to the home, is calling on the Government to deliver a 40% carbon emissions reduction from the existing housing sector by 2020.

So far, WAG have made progress with energy performance programmes, including the fuel poverty scheme, reducing fuel bills for those who need it most.

Mr Cranna's home will join others across the UK as part of the 'OldHome SuperHome network' and houses in the scheme range from the smallest of Victorian terraces to a 17th Century Grade 2 listed thatched cottage.

He said: "You don't need to knock the housing down. What they show is you can do something with the existing housing stock."

Some of the 200 houses in the SuperHomes network will be open to the public in the coming months.
