Part L2 (2013/2014) EPC

So far we have covered the SBEM Compliance route only. The differences for the SBEM-EPC method are covered in this section.

 

·       Assessor name

·       Assessor number – this automatically sets the Accreditation scheme.

·       Qualifications

·       Trading name

·       Trading address

·       Related party disclosure (**)

·       Transaction type (**)

(**): the last two items cannot be left unset. No EPC can be generated until both are set.

·       Insurance company

·       Policy number

·       Start date

·       Expiry date

·       Professional Indemnity Limit (£)

This section has additional EPC data – the first two (Date, UPRN) *must* be filled in correctly, because the unique Certificate number will be generated from them.

·       Inspection Date

·       UPRN (12 digits, taken from national database)

·       Does the building have special conservation status?

This information will be included in the XML to be lodged in the national register.

The available NCM recommendations are listed by Category which can be selected from the left hand list. Another way of selecting NCM recommendations is through the Code selector at the top. NCM recommendations cannot be deleted.

The user may modify NCM recommendation data (except the Text) and then three things occur:

·       The recommendation changes from green to blue in the list

·       The bottom frame shows “(EDITED)”

·       The “Revert to NCM” button becomes enabled.

“Revert to NCM” will discard the user’s changes and reverse the above three actions.

The user may add new recommendation(s) in the current Category using either the Add or Copy buttons. These appear blue from the beginning and can be deleted.

The user may exclude any recommendations (green or blue) from consideration by SBEM, by double clicking the tickbox in the list. These then change from green or blue to grey. Double clicking the cross back to a tick will include them again and return to the original colour.

In the Recommendations Report, the recommendations will appear as follows:

Section (a) Green NCM recommendations triggered by SBEM and with a payback of less than 3 years, listed in increasing order of payback

Section (b) Green NCM recommendations triggered by SBEM and with a payback of 3 to 7 years, listed in increasing order of payback

 Section (c) Green NCM recommendations triggered by SBEM and with a payback of over 7 years, listed in increasing order of payback

 Section (d) Blue NCM recommendations triggered by SBEM *and* all blue USER recommendations (no trigger for these), listed in increasing order of payback

Grey NCM recommendations will not appear at all, even if SBEM would have triggered them.

Grey USER recommendations will not appear at all.

 

Note: some information in the VE interface does not appear in the Recommendations Report, as follows.

o   Assessor comment

o   Energy impact

o   CO2 saved per £ spent

o   Applicable to a specified HVAC/DHW System

(The Payback does not appear directly but does define the layout and order of the Report as described above).

Use these, as advised by your IT department, only to resolve issues with connecting to the Landmark server EPCgen.net.

A “Generate EPC” button appears instead of “CO2 Emissions: Part L compliance”

 

 

The target building emissions rate, derived from the Notional Building Emissions Rate (C_notional)

The Building Emissions Rate (kgCO₂/m2) calculated for the notional building, adjusted by a fixed improvement factor of 0.235 as follows:

C_standard = C_notional x (1 – 0.235)

The Building Emissions Rate (kgCO₂/m2) calculated for the actual building.

The ratio of the Actual emission to the Standard emission, where 50 corresponds to a 1:1 ratio:

EPC Rating = (C_actual / C_standard ) × 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 = (C_TER / C_standard ) × 50

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.

·       <buildingname>_not_sim.csv                    The calculation details for the Notional building

·       <buildingname>_dr.csv                The data reflection report for the Actual building

In this folder you will also see a secondary, more detailed, Recommendations Report PDF and the XML file to be lodged in official databases.
