What is are SAP Calculations for Scotland?

In Scotland, Section 6 of Building Standards must be complied with for all new dwellings. The same rules that apply to England and Wales when it comes to SAP Calculations are applied here too, however Scottish regulations tend to be a bit more rigorous than in the rest of the UK.

The main objective to achieve compliance with these calculations is to make sure that the Dwelling Emission Rate (DER) and Dwelling Fabric Energy Efficiency (DFEE) rate is lower or equal to the Target Emission Rate (TER). The former describes the actual emission rate of your constructed or designed property while TER represents an estimation based on a property with similar dimensions as this one but in Scotland also assumes that some form of renewable energy has been used.

Scottish Government has confirmed that the implementation date of the Section 6 (Energy) Standard 2022, will be moved from the 1st December 2022 to 1st February 2023. This means any Building Regulation applications received after 1st February 2023 will need to comply with the updated standard assessment procedure. We hope this news helps in your planning and assures you of our commitment to keeping you informed and up-to-date!

What is Section 6 (Energy)?

Are you looking to construct a new residence or commercial building in Scotland? If so, you’ll need to adhere to Section 6 of the Building Standards – which covers energy efficiency, ventilation and overheating prevention for residential and non-residential buildings.

To ensure your construction meets standards, specialist energy compliance software is used to calculate performance levels before and after completion. In Scotland, local authorities are allocated as ‘verifiers’ who assess designs and building checks independently; guaranteeing all regulations have been met.

We are pleased to confirm that the Scottish Government’s Technical Handbooks webpage will soon be updated to reflect the decision to postpone the formalisation of an amendment to the Building (Scotland) Regulations 2004.

Please note: Standard Assessment Procedure, or SAP Calculations, are different from an Energy Performance Certificate. Typical SAP Calculations are used to demonstrate to building control how a building or conversion will comply with building regulations due to a ‘material change’ or ‘change in energy status’ while an EPC demonstrats the energy efficiency of a building.

Frequently Asked Questions

What are SAP Calculations?

SAP stands for ‘Standard Assessment Procedure’ and is the government’s method for calculating the energy performance of dwellings. These calculations are only necessary for residential properties. The calculations determine a Target Emissions Rate (TER) and a Target Fabric Energy Efficiency (TFEE) rate.

How much is a SAP Calculation?

Our fees are typically based upon the size and complexity of a dwelling. We do prefer to offer a bespoke quotation on a job-by-job basis to give you the best price – So get in contact and send us your plans today!

What is required for a SAP Assessment?

Your Assessor would advise you of exactly what is needed. Typically you would need the following:

  • Floor plans, sections & elevations
  • Orientation e.g. site plan
  • Construction specification of walls, roofs and floors
  • Specification for all windows
  • Primary & secondary heating systems
  • Renewable technology (if any)
What happens if my design fails its SAP Assessment?

If your design fails its SAP Assessment, then you will need to revise the design to meet the requirements. Depending on the extent of the changes required, you may need to go through the assessment process again. In some cases, you may need to have additional testing done to verify the design’s performance. The SAP Assessor will provide guidance on the necessary steps to make your design meet the requirements.

Are SAP Calculations different in Scotland to England and Wales?

Yes, SAP calculations for projects in Scotland are different from those in England and Wales. This is because the Scottish Building Regulations have different requirements for energy performance in buildings compared to the regulations in England and Wales. In Scotland, the SAP calculation must be carried out by a qualified and accredited assessor, and the results must be submitted to the local authority as part of the building control process.Also the Dwelling Fabric Energy Efficiency (DFEE) target is not applicable in Scotland, but the elemental U-Value limits are stricter.

In England and Wales, the SAP calculation is part of the mandatory EPC that must be produced when a building is built, sold, or leased. Therefore, it is important to use an experienced and qualified assessor who is familiar with the specific requirements of the Scottish Building Regulations when carrying out SAP calculations for projects in Scotland.

SAP Calculations for all your building projects

If you are planning a New Build or Conversion, you may need additional services that our experts can assist with, for example Residential Air Testing, Sound Testing, Ventilation Testing, U-Value Calculations, Water Efficiency Calculations, Thermographic Surveys, Energy Performance Certificates, Part O Overheating Calculations, London Plan and Thermal Bridging Calculations.
