3 PRO INSTALLER JUNE 2015 PRO NEWS @proinstaller1 FIRST ‘A++’ RATING FOR ENERGY EFFICIENT WINDOWS LAUNCHED BFRC has officially launched the applications process for the first ‘A++’ band in England & Wales for Window Energy Ratings (WERs). There will be four months for window companies to develop new ‘A++’ product as the first licences will not be issued until 1st October 2015 – with the first ‘A++’ product being launched shortly afterwards. ‘BFRC is driving technological developments’ BFRC follows the 10 point band cut offs illustrated in section 4.2 of Approved Document L1b’. The new ‘A++’ rating will be no different, with ratings starting at an energy index value equal to or greater than +20. This means any BFRC ‘A+’ rated product which achieves 20 or more can be upgraded to an ‘A++’ for an administration and verification fee of £100 (ex VAT). Alternatively, manufacturers can also apply for new ‘A++’ licences. All applications must be accompanied by a simulation report and can be made either directly to BFRC or through an Independent Agency. These new ‘A++’ licences are available both as Simplified Energy Licences (SELs) and Detailed Energy Licences (DELs). “The launch of the BFRC ‘A++’ ratings band – the first in the country – reinforces the message that BFRC is driving technological developments that give homeowners the latest and best in energy efficient windows,” comments BFRC managing director Chris Mayne. “And contrary to some ill-informed comment within the industry ’A++’ rated windows will not cause homes to overheat.” ‘A++’ and the Overheating Misconception Overheating in a domestic situation happens when the internal room temperature Taking up the Challenge The weekend of the 26th - 27th June will see members of staff from The VEKA UK Group taking to two wheels to raise funds for the company’s nominated charity, The Encephalitis Society. The cyclists’ route will cover 100 miles of beautiful Wiltshire countryside over the two days, passing landmarks such as the Avebury Stone Circle, Stonehenge and the Wiltshire White Horses. Support for the charity was decided after Mark Barsby, Head of Technical was diagnosed with an autoimmune form of Limbic Encephalitis last year. He, in discussion with Head of Commercial Sales, Richard Garland and Head of Product Management, Steve Bakewell, planned the challenge as part of the company’s yearlong fundraising programme for the charity. Mark explained: “I wanted to do my bit and put something back for the help The Encephalitis Society had given me. Steve gave us some ideas as he had already taken part in similar events to raise money for charity. “I decided to make some changes to my diet and exercise more when I came out of hospital. As part of my goal, however, I’ve promised myself an ice cold beer and a hot sausage roll on completion of the second day as they’re probably the two things I’ve missed the most!” Colin Torley, Sales and Marketing Director for The VEKA UK Group said: “The support Mark received from The Encephalitis Society made it an obvious candidate for our support. We normally work with charities for six-month periods but this cause is so close to our hearts that, in this case, we decided to dedicate a full year’s support.” www.encephalitis.info becomes higher than the comfort level, and cannot be reduced by simply opening the windows. It can be caused by two factors:The first is high external ambient temperatures, which can lead to high internal ambient temperatures due to heat conduction through the building envelope (including, but not limited to, windows). But ‘A++’ (and ‘A+’) windows have significantly lower U values than lower rated windows, so they will reduce the amount of heat being transferred into the home from outside. With existing glass coating technology, there is a hard physical upper limit to solar gain performance that cannot be exceeded, so the only way to achieve higher ratings bands is through lower U values. The second cause of overheating is excessive solar gain - particularly on south facing elevations. It is expected that all ‘A++’ windows (and about 70% of ‘A+’) use triple glazing, with two panes of low-e coated glass. Their solar gain factor is significantly lower than the equivalent double glazed window. So all BFRC ‘A++’ rated windows (and the majority of ‘A+’) will actually help to reduce overheating during the summer months. In the winter they will help keep the home much warmer. “A further benefit to ‘A++’ windows is their lower U values give warmer internal surfaces effectively eliminating the risk of internal condensation,” adds Gary Morgan BFRC technica
