Conservation of Fuel and Power

The Technical Handbooks provide guidance on achieving the standards set in the Building (Scotland) Regulations and are available in two volumes, one for domestic buildings and non-domestic buildings.  Section 6 of both handbooks covers energy.

Updates to the Technical Handbooks came into effect on 1st July 2017.


For existing homes in Scotland, the Window Energy Rating (WER) is now an established route to compliance for replacement windows in dwellings and windows for extensions.  WER is a better indicator of the energy performance of a window than the simple U value because it takes into account a range of factors, including passive solar heat gain.

Solutions to meet the requirements of building regulations include the Pilkington Optitherm™ and Pilkington K Glass™ ranges of low emissivity glass that can be combined with Pilkington Activ™ self-cleaning glass and Pilkington Optiphon™ to give a broad choice of thermal and other properties.  Particularly for non-dwellings, Pilkington Suncool™ is a range of solar control glass products that combine low emissivity glass, low U values with solar control with neutral appearance. 

A recent innovation in energy efficiency is Pilkington energiKare™ Advantage which can provide triple glazing performance in a double glazing.
