Specifications as of May 2008

The specification shown will, in most cases, meet the Scottish Building Standards Section 6 - Energy, when mains gas is used as the primary fuel source.

Section 6: Energy

This section of the Scottish Building Standards sets out detailed requirements for the energy efficiency in all new dwellings.

These now differ markedly from the pre May 2007 standards in that their criteria for compliance, is based upon limiting the overall CO2 emissions of the property, such that an 18 - 25%.overall reduction is achieved.

Designers now have to take into account not only the fabric of the dwelling (floor, wall, roof, windows & doors) but also the primary and secondary heating fuel sources (mains gas, electricity, oil, solid fuel, lpg or bio mass), boiler efficiency, method of hot water storage and heating controls. Also taken in to account are low energy lighting and whether renewables such as solar panels, photovoltaics and wind turbines are to be fitted. Once the CO2 emissions (which are expressed in kg(m2.yr) are calculated, the dwelling is issued with an Energy Performance Certificate.

Having our own Approved Certifier Of Design For Energy for Scotland, means Scotframe are uniquely placed to 'Thermally Engineer' your home to ensure these Building Standards are met as cost effectively as possible. This assures you of compliance with current requirements and also affords you the opportunity to 'future proof' your home by exceeding them prior to further changes which will come about in the next standards review, scheduled for 2010 and again in 2013.

Please note: The Standards in England, Wales & Northern Ireland differ from those in Scotland, so please contact us for further details.
