*contributes to 50 credits available for operational energy rating
To minimise operational energy consumption and the associated carbon emissions by generating renewable electricity.
- What is the quantity of energy generated by on-site and community renewable energy schemes in kWh per year (as metered in the reporting period)?
- What is the net quantity of electricity exported off-site in kWh per year (as metered in the reporting period)?
|1||To qualify as on-site or community renewable energy the generation source must be located on or near to the asset and must be connected to the asset using a private wire arrangement.|
|2||Assessors must confirm that the metered electricity data relates to the start and end date|
The intention is that the user enters energy consumption data based on a 365-day reporting period; for both years. However, it is possible to enter data for any reporting period between 11 and 13 months. Any reporting period outside of the 11 to 13-month range would be invalid and result in zero credits being scored.
|-||The evidence below is not exhaustive, please also refer to the ‘BREEAM evidential requirements’ section in the scope of the Guidance for appropriate evidence types which can be used to demonstrate compliance.|
|1||Photographic evidence of relevant generation and export meters|
|2||BEMS data or copies of verified data for the reporting period specified|
Private wire arrangement:
A private wire arrangement is one where electricity generated, on or in the vicinity of, the site is fed directly to the building being assessed, by dedicated power supplies. Electricity which is surplus to the instantaneous demand of the building, may be fed back to the grid supply network.
