This tab allows for the input of data used in ratings analysis common to the two types of ratings analysis, and certain additional information required for compliance or BER generation. The screenshot below is for BER generation. For compliance the format is mainly identical but lacks the ‘BER’ section.
Location Description
Descriptive text may be entered here.
Adjustment for management features
These settings allow credit to be taken in the BER calculation for management features applied to electrical power and lighting.
· Electric power factor
· Lighting systems have provision for metering?
· Lighting systems metering warns of ‘out-of-range’ values?
Project Complexity
Set the project complexity according to official guidance.
Stage of analysis
Set whether the building is analysed ‘Existing Building - Final’, ‘New Building - Final’ or ‘New Building – Provisional’.
District Heating
This section is only active when a system with Heat source/fuel type set to District Heating is assigned to a room in the building.
District Heating CO2 Conversion Factor: Enter the CO2 Conversion Factor to be used by systems whose heat source/fuel type is District Heating.
Primary Energy factor: The conversion factor used to calculate the Primary Energy consumption associated with the District Heating system energy use
Renewable primary energy factor: Specifies the renewable primary energy conversion factor (for renewable heat sources only) if the fuel type ‘District Heating’ is used anywhere in the building for space and/or water heating.
RER
Primary energy exported: Specifies the total process primary energy which is exported annually.
Primary energy used: Specifies the total process primary energy which is used annually.
Has LENI lighting calculation been carried out? (compliance only)
Specifies whether a calculation following the Lighting Energy Numerical Indicator (LENI) method has been carried out for the building as an alternative to complying with the lighting efficacy standards as specified in the Non-Domestic Building Services Compliance Guide.
The following parameters apply to BER analysis only
Construction date: The date on which the building was constructed. Enter in the format (yyyy, mm, dd).
MPRN: The Meter Point Registration Number (MPRN) of the building (must be 12 digits).
Air Conditioning
Enter details of the air conditioning system in the building. Not used in calculations (HVAC data is defined in Apache systems/System Wizard) but instead used in BER report.
Aircon system present?: Specify if air conditioning system is present in the building (if applicable).
Total effective rated output: If actual output is known then choose ‘EXACT’ and enter value in ‘exact rated output’ input else choose dropdown option that matches estimated value.
