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.
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.
Information on approved software and on use of such tools to meet these requirements is included in the attached document.
