The new homes will take heat energy from the rocks beneath them A former Tomorrow's World presenter has branded new energy reports "insane" after purpose-built 'eco homes' were given a low efficiency rating. Lindsey Fallow said Energy Performance Certificates (EPCs) were made using a "glorified spread sheet" and did not recognise advanced technologies. It comes after a firm she is involved with scored low ratings on four new homes in South Lanarkshire. Apex Developments said EPCs were "not worth the paper they are written on". It said the technologies it used to reduce carbon emissions at its Lethame Courtyard development on the outskirts of Strathaven had not been recognised in the assessment process. The four new homes feature green technologies that the developers said reduced the carbon footprint of a large family home down that of a small one-bedroom flat. It seems insane to leave something so important down to what is essentially a glorified spread-sheet that only takes into account the basic technologies

As part of the Home Information Packs, introduced in Scotland last year, EPCs are now required by law to be completed when properties are sold or rented out. Former presenter Ms Fallow has been working with Apex on developing software which calculates how energy efficient certain technologies are. She said: "I was stunned when I saw the EPCs for these houses as I know the work that has gone into making them as 'green' as possible. The houses feature energy efficient heating systems "It seems insane to leave something so important down to what is essentially a glorified spread-sheet that only takes into account the basic technologies and does not recognise the more advanced ones. "It makes the whole process of getting these certificates seem like a complete waste of time." Alan Simpson from Apex Developments told the BBC Scotland news website: "We had done our own calculations which gave us a very high energy efficiency rating but when we had our EPC rating done it was not as good. "When we asked why, we were told the computer software did not recognise the technologies we had used. "These are not really new technologies. These systems have been in use by developers in places such as Scandinavia for about 30 years." He added: "We were disappointed at first and then we got angry. "We have to give these certificates to our customers and it looks like we are not telling the truth. We are keeping the assessment procedure under review to take account of regulatory and technical developments that have arisen

Scottish government spokesman "It shows their house as being a C or a D rating when we believe it should be an A or at least a high B." In Scotland the Energy Saving Trust holds the register of Energy Performance Certificates but a spokesman said overall responsibility for carrying out the assessments and providing the ratings lay with the Scottish government. A government spokesman said: "Energy Performance Certificates will improve energy efficiency and make an important contribution to achieving our world leading climate change targets. "We are keeping the assessment procedure under review to take account of regulatory and technical developments that have arisen." Mr Simpson said: "We think that, in theory, EPCs are a good thing, but the way in which the assessments are carried out must be updated and improved to allow builders to demonstrate what they are doing effectively, and give them the recognition they deserve."
