EPC Process in Scotland

DesignBuilder v3.2 includes SBEM 4.1.e and is approved for use in generating Scottish EPCs and Section 6 Building Regulations Compliance reports. It is not yet approved in England and Wales, Northern Ireland and Republic of Ireland.

The following existing inputs are now required for Scottish assessments (project details):

• UPRN: Unique Property Reference Number-extended for Scottish use (10 digits as oppose to 12 digits for rest of UK)
• Building Inspection Date
• Transaction Type
• Primary Energy conversion factor for District heating Systems (only available once a district heating system has been specified)

The following are new parameters introduced in SBEM v4.1.e:

1. Project details

1. Your email address
2. Accreditation scheme web address
3. Restriction status of xml
4. EPBD Recast (new buildings only)

2. On calculation dialogue (EPC)

• England and Wales Asset Rating

Guidance on providing the E & W Asset Rating for Scottish EPCs

When you have completed the building specification and QA checking ready to do final EPC calculations then you will be ready to produce a comparative E + W Asset Rating. You may be wise to backup your dsb file before doing this.

Simplified Process

1. Temporarily change the UPRN to a 12 digit number as required for E&W assessments, for example you could add 00 to the beginning of the correct UPRN. This is set in Model Options on the Project Details tab.
2. Click on the Calculate tab and Update. Select Assessment Type EPC England or EPC Wales
3. When calculation complete note down the numerical Rating from the EPC or Summary Report. Check on the summary report that the Weather is set to GLA. If not then use the more detailed instructions below
4. Reset UPRN
5. Enter E & W Asset Rating on Calculate dialogue, check that calculation type is set the EPC Scotland
