EPC Card User Guide

* EPC Coverage does not depend on the date picker, unlike other cards on the Fund Dashboard. EPC Coverage is always displayed as of the day you are viewing the page. This is to avoid confusion as to the status of the portfolio, and help you focus on managing current coverage gaps. 

Floor Area Coverage

“Floor Area Coverage” shows the proportion of the total portfolio area which is covered by EPCs. The denominator of this percentage is the total Gross Internal Area (GIA) of the assets in the portfolio.

Each valid EPC in the portfolio contributes area coverage, proportionally to the area of the asset it corresponds to. EPCs in SIERA can be entered as covering the Whole Building, or a single Unit of the building. These contribute covered area as follows:

• If an asset has a valid EPC with a scope of “Whole Building”, the GIA of the asset is counted as covered.
• If the only valid EPCs at an asset are Unit-level, then the floor area of each Unit with a valid EPC is counted towards the covered area.
• If there are multiple Whole Building EPCs for the same asset, the floor area covered will still only be counted as the GIA of that asset, to prevent over-counting.
• If an asset has both valid Whole Building and Unit-level EPCs, then the Whole Building EPC(s) will take priority, and the unit level EPC(s) will be ignored.

EPC Distribution

The EPC Distribution by floor area shows how the total floor area coverage is split out between rating categories. Expired EPCs are not included in the floor area coverage for a category. The total of the percentages across all the categories will be equal to the overall Floor Area Coverage shown at the top of the card. The percentage for each category is calculated exactly like the overall Floor Area Coverage, with only EPCs in that category contributing to covered area.

Expiring in the next 12 months

The final bar in the EPC card shows the proportion of EPC floor area coverage which comes from EPCs expiring in the next 12 months (starting from the day on which you’re viewing the page). If no action is taken to renew these EPCs, this coverage will be lost from your portfolio, and certain assets may be in breach of compliance requirements, depending on local regulation.

Renewing expiring EPCs is also an opportunity to improve the EPC rating distribution of your portfolio; energy efficiency measures installed since an asset’s last EPC assessment can increase the score and rating of the asset when it is re-assessed.

Examples for EPCs included in the current reporting year of 01/01/2023 - 31/12/2023

 

EPC Expiry Date	Included In submission
31/12/2022	No
01/01/2023	Yes
01/11/2023	Yes
01/01/2024	Yes

 

 

Weighted Letter Rating Score

For EPC schemes which are mapped to the GRESB scheme of “EU EPC”, a letter rating is required to be calculated as well (A+ - G). This shall be based on a floor area weighted score ( numerical value) which is then aligned to the letter rating bandings for that specific scheme.

 

Asset	Unit	Unit Area	EPC Score	Area Weighting of asset	Area Weighting of relevant EPCs	Weighted Score
A	1	100	40	100/1000= 0.1	100/850= 0.12	0.12*40=5
A	2	750	90	750/1000= 0.75	750/850= 0.88	0.88*90=79
A	3	150	No EPC	150/1000= 0.15	0
Total		1000				84

 

Notes:

• The value used the area weighting of EPCs score only considers valid EPCs. EPC records tagged as “No EPC “, ”Exempt” or which have expired before the start of the current reporting year are ignored.
• If there are multiple whole building EPCs for the same asset, and a weighted score is required, the whole building EPCs should be treated as having equal weighting.

Rating	Scheme “England & Wales Non-Domestic”	Scheme “Scotland Non-Domestic”
A+	From -999 to -1
A	0 - 25	0 - 15
B	26 - 50	16 - 30
C	51 - 75	31 - 45
D	76 - 100	46 - 60
E	101 - 125	61 - 80
F	126 - 150	81 - 100
G	151 - 999	101 - 999

 

If Asset A had EPCs assigned to the scheme England & Wales Non- Domestic then then the scheme reported would be “EU EPC - D” however if the scheme assigned to the EPC is “Scotland Non Domestic”, then this would be reported to GRESB as “EU EPC - F”.
