This content is not being updated. The latest Scottish Government policy on building standards can be found on https://beta.gov.scot. Current Building Standards technical handbooks are still in the Technical Guidance section on this website.

Section 6 Software

Calculation software implementing the UK National Calculation Methodology (NCM) is used in Scotland for three purposes:

  • Demonstrating compliance of new buildings with Standard 6.1 (Carbon Dioxide Emissions) under building regulations
  • Producing Energy Performance Certificates for new buildings and where existing buildings are to be sold or rented and for display in ‘public buildings’; and
  • For production of Action Plans or Display Energy Certificates in building subject to The Assessment of Energy Performance of Non-domestic Buildings (Scotland) Regulations 2016.

Information on approved software and on use of such tools to meet these requirements.

Note that, from 6 April 2018, tools implementing v5.4b of SBEM can be used to demonstrate the compliance of new non-domestic buildings with standard 6.1 (carbon dioxide emissions). Current tools implementing v5.3a of SBEM may also continue be used for calculations submitted in support of a building warrant on or after this date. 

Users are directed to the updated documentation on v5.4b for Scotland available on the NCM website (https://www.uk-ncm.org.uk/) and to the updated NCM Modelling Guide for Scotland and Non-domestic Building Services Complaince Guide, both available at: http://www.gov.scot/Topics/Built-Environment/Building/Building-standards/techbooks/techhandbooks.

Both v5.4b and v5.3a tools may currently be used for EPC lodgement to the Scottish EPC Register (https://www.scottishepcregister.org.uk/). The next update to the Register (Summer 2018, date to be confirmed) will prevent the future use of v5.3a for EPC lodgement.
