The Government has set itself a specific target of ensuring all new homes built after 2016 are zero carbon. This is in addition to the general requirement of an overall carbon emission reduction as set out by the Kyoto agreement. To highlight this topic and enable a system which is both an independent source of information and also easy to understand, the BFRC (British Fenestration Rating Council) working in conjunction with the Energy Efficiency Council, have created a performance label clearly defining the energy efficiency of windows from any manufacturer. Launched in March 2004, the Window Energy Rating label is similar to that used on many white goods in our homes, such as fridges and washing machines. Windows are scored on a scale of A – G, with an A rated building product being more energy efficient than one which is G rated.
This allows individuals to quickly and easily choose the windows most suitable for their needs. In an ideal world, A rated windows would be installed in each home in the UK. However, recognising that a balance needs to be made between the availability and cost-effectiveness of such products, those which are given a rating of C and higher are recognised as energy efficient, and can officially be endorsed with the Energy Saving Recommended logo.
A rated windows are as minimum energy neutral which means that the window gains just as much warmth as it looses during the heating season. The specific energy data are of course linked to its location relative to the sun, so the equation for an energy-neutral window is based on an average, that the house windows are located 41% south, 33% east / west and 26% north. - However values are different in each country.
