SettingDescription
Select Rooms Click to select and deselect the rooms in the report. Clicking the icon changes the layout of dialog. Rooms can be selected/deselected individually by clicking on them, or select/deselect all by clicking Select All or Select None.
  • Select All - Selects all the rooms with a single click.
  • Select None - Deselects all the rooms with a single click.
  • Select Zone - Selects a zone which contains one or more rooms.
  • Select Floor - Selects a floor of the room.
Project Details The Type of analysis, Building location, Stage of analysis and the Project Complexity can be specified in the Project Details tab.
  • Type of analysis - Refers to the type of analysis that will be carried out using SBEM, for example, Northern Ireland Building Regulations Part F 2012.
  • Building location - Used to select the nearest city to the project site from the available locations in the Northern Ireland.
  • Stage of analysis - Specifies whether the building is As designed (new building) or As built (existing building).
  • Project complexity - Refers to the complexity of the building for the purposes of energy assessments for EPCs.
    • Level 3 - Simple, existing buildings that can be modelled using SBEM, for example, small buildings such as converted houses or doctor's surgeries.
    • Level 4 - New and existing buildings that can be modelled using SBEM , for example, small purpose-built office buildings.
    • Level 5 - New and existing buildings complex buildings that need to be modelled using Dynamic Simulation Models (DSMs), for example, large office buildings or factories.
  • Related party disclosure - Used for any related party disclosures by the Energy Assessor for the purposes of energy calculations for EPCs.
  • Transaction type - Used to select the Transaction type.
Building Details
  • Name - Displays the building name.
  • Address - Used to enter the building address.
  • City - Used to enter the city in which the building is located.
  • Postal code - Used to enter the building Postal code.
  • Location description - Used to enter the description of the building location.
  • UPRN - The Unique Property Reference Number (UPRN) of the building. This parameter is active only if the analysis is set to EPC generation. In England, Wales, and Northern Ireland, this parameter consists of 12 digits while in Scotland, it consists of 10 digits. It should not be left blank.
  • RRN - The Report Reference Number (RRN) of an EPC was previously done for the building in England, Wales, or Northern Ireland. This parameter is active only if the "Purpose of Analysis" parameter is set for generation of EPC in England, Wales, or Northern Ireland, and the UPRN cannot be provided. It consists of 20 digits in the form of five sets of numbers separated by hyphens, where each set is comprised of 4 digits (the software will add an "RRN-" prefix).
  • Inspection date - The date on which the energy assessor inspected the building for the purposes of energy calculations for EPCs.
  • Building Type - The choice of building type here sets the default building type for the activity areas that will be defined later. It is possible to change the building type for each of the activity areas when defined. Choose the building type that most closely defines the majority of the building.
Certifier The pane contains the certifier/energy assessor's details.

The name, address, city, postcode and the telephone number of the energy assessor.

  • Name - The Name of the certifier, energy assessor, agent, or qualified/accredited person. The text input in this field should not include any double quotes.
  • Address - The Address of the certifier, energy assessor, agent, or qualified/accredited person. The text input in this field should not include any double quotes.
  • City - The City of the certifier, energy assessor, agent, or qualified/accredited person. The text input in this field should not include any double quotes
  • Postal code - The Postal code of the certifier, energy assessor, agent, or qualified/accredited person. The text input in this field should not include any double quotes
  • Telephone - The Telephone of the certifier, energy assessor, agent, or qualified/accredited person.
  • Email - The Email of the certifier, energy assessor, agent, or qualified/accredited person.
  • Accreditation scheme - The name accreditation scheme to which the energy assessor belongs becomes visible in the interface after the user enters the Assessor Number (the parameter below), for EPC Calculations in England, Wales, and Northern Ireland. The name of the accreditation scheme will correspond to the Assessor Number input.
  • Registration number - The registration number of the energy assessor within his Accreditation Scheme. This parameter is active only if the "Type of Analysis" parameter is set to 'EPC England', 'EPC Wales', or 'EPC Northern Ireland'. This parameter must consist of 4 capital letters followed by 6 digits, and it should not be left blank.
  • Qualifications - The qualifications of the energy assessor as they will need to be qualified for the type of building being assessed (check with your accreditation scheme). This parameter is active only if the "Type of Analysis" parameter is set to 'EPC England', 'EPC Wales', or 'EPC Northern Ireland'.
  • Emp/trading name - The employer or the trading name of the energy assessor. This parameter is active only if the "Type of Analysis" parameter is set to 'EPC England', 'EPC Wales', or 'EPC Northern Ireland'. The text input in this field should not include any double quotes.
  • Emp/trading address - The employer or the trading address of the energy assessor. This parameter is active only if the "Type of Analysis" parameter is set to 'EPC England', 'EPC Wales', or 'EPC Northern Ireland'. The text input in this field should not include any double quotes.
  • Assessor Comp. No. - The registration number of the energy assessor within his Accreditation Scheme. This parameter is active only if the "Type of Analysis" parameter is set to 'EPC England', 'EPC Wales', or 'EPC Northern Ireland'. This parameter must consist of 4 capital letters followed by 6 digits, and it should not be left blank.
Important: Energy assessors should input full details (name, address, qualifications, name of Accreditation Scheme Provider, trading name, etc.) in the interface exactly as they want them to appear in the XML file and on the lodged EPC, as well as their assessor number. The new verification system will not overwrite these details with information from the National Register.
Insurance and Owner The pane contains the energy assessor's insurance.
Insurance - The Insurance details of the building including the Policy number, Effective date, the PI limit etc, are given.
  • Insurer - Used to enter the name of the energy assessor's insurance company.
  • Policy number - Used to enter the energy assessor's insurance policy number.
  • PI limit - Used to enter the energy assessor's insurance policy cover limit.
  • Effective date - Sets the energy assessor's insurance policy effective start date.

Special Considerations The pane specifies various factors and status marked in the checklist that determine the health of the building.
  • Building is of special conservation status
  • Building is a shell and core development
Building is of special conservation status (Special considerations tab) – the building has been identified as being:
  • Of special architectural or historical interest.
  • In a conservation area.
  • In a designated area of special character or appearance.
  • Or of a traditional construction.
EPBD Recast The pane specifies various environmental factors that determine energy usage and conservation.
Set the applicable checks that have adopted in the building design.
  • Renewable energy system.
  • CHP
  • District heating and/or cooling
  • Heat pump
By submitting above facts you will agree upon assessment and inspection, as needed.

Before running any calculations (SBEM or DSM), a baseline must be calculated. Also a scenario has to have a measure to be able to run (SBEM and DSM).

Note: The Window Tittle bar reflects current scenario and measure. Adding measures to a scenario are cumulative.
