Part L2 (2006) VE-SBEM Results
This tab on the dialogue at the lower edge of the <VE> Compliance screen allows you to view the results of Part L2 (2006) calculations.
Because the results are very different, SBEM and SBEM-EPC methods are discussed separately.
SBEM method
Building Emissions Rate (BER)
The Building Emissions Rate (kgCO2/m2) calculated for the actual building.
Notional Building Emissions Rate
The Building Emissions Rate (kgCO2/m2) calculated for the notional building (Cnotional).
Target Emissions Rate (TER)
The target building emissions rate, derived from the Notional Building Emissions Rate (Cnotional) by applying the Improvement Factor and LZC Factor using the formula:
TER = Cnotional × (1 – improvement factor) × (1 – LZC)
Improvement Factor
A preset factor determining the degree to which the TER must improve on the Notional Building Emissions Rate (Cnotional).
LZC Factor
The Low and Zero Carbon benchmark, which together with the Improvement Factor determines the degree to which the TER must improve on the Notional Building Emissions Rate (Cnotional).
Did the analysis pass the CO2 emissions rating?
The pass/fail result for Criterion 1. ‘YES’ if BER<TER, ‘NO’ otherwise.

Extra output files
Two further output files are copied to the project’s Regs\SBEM\BRUKL folder and may be of interest. Both are in comma-separated format.

SBEM-EPC method
Part L TER
The target building emissions rate, derived from the Notional Building Emissions Rate (Cnotional) by applying the Improvement Factor and LZC Factor using the formula:
TER = Cnotional × (1 – improvement factor) × (1 – LZC)
Typical
The Building Emissions Rate (kgCO2/m2) calculated for the typical building.
Standard
The Building Emissions Rate (kgCO2/m2) calculated for the reference building, adjusted by a fixed improvement factor of 0.235 as follows:
Cstandard = Creference x (1 – 0.235)
Actual BER
The Building Emissions Rate (kgCO2/m2) calculated for the actual building.
Asset Rating, Band
The ratio of the Actual emission to the Standard emission, where 50 corresponds to a 1:1 ratio:
EPC Rating = (Cactual / Cstandard ) × 50
The band letter and colour corresponding to this (as also shown on the EPC) is shown under the Actual emission figure.
The Part L and Typical bands are also shown, based on similar formulae (the numerical rating values are shown on the EPC).
Part LRating = (CTER / Cstandard ) × 50
Typical Rating = (Ctypical / Cstandard ) × 50

As noted at the end of Section 4.4, some of the Recommendations data in the VE interface is not output by SBEM v3.0.

Two further output files are copied to the project’s Regs\SBEM\EPC folder and may be of interest. Both are in comma-separated format.

In this folder you will also see the XML file to be lodged in official databases.
