Scottish handbooks

Effective from 1st February 2023 (deferred from 1st December 2022), the Scottish Government has introduced changes to Sections 3 (environment), 6 (energy) and 7 (sustainability) of the Building Standards Technical Handbooks for domestic and non-domestic buildings.

These changes form part of the output from the Building Standards Energy Review Panel and measures proposed within the 2021 consultation on energy standards.

Section 6 on energy has been revised to introduce a delivered energy target for new buildings and an amendment to the notional building specifications to set compliance targets.  The area-weighted average U values for fabric elements have been improved and one set of values now apply to all buildings.

For new dwellings, Section 3.28 introduces a new mandatory standard to assess and mitigate the summertime overheating risk.

Through our hub, we provide a summary of each section of the new requirements relevant to glass and glazing.

If you have any questions on changes and what the implications might be for glass, please complete our online contact form, selecting 'Architect' or 'Trade' as the Nature of Enquiry and 'Other' as the Enquiry Type.
Please state 'Technical Handbook Section 6' in the Question / Comment box when completing the form.

Our Spectrum online calculator can be used to quickly determine the g value and centre pane U value for our range of thermal insulation and solar control glass.
