Residential (2 credits available)
Aim
To recognise and encourage monitoring of energy consumption through the use of energy display devices.
Assessment criteria
The following is required to demonstrate compliance:
One credit
1 | Current electricity OR primary fuel consumption data are displayed to occupants through a compliant energy display device. |
Two credits
2 | Current electricity AND primary fuel consumption data are displayed to occupants through a compliant energy display device. |
Checklists and tables
None.

Applicable assessment criteria |
Both options: This issue is not applicable. Refer to Appendix D – Shell and core project assessments for a more detailed description of the shell and core assessment options. |
Residential - Partially fitted and fully fitted |

Applicable assessment criteria - Single dwellings |
Partially fitted: This issue is not applicable Fully fitted: All criteria relevant to the building type and function apply. Refer to Appendix E – Applicability of BREEAM New Construction to single and multiple dwellings, partially and fully fitted for a more detailed description of residential assessment options. |

Applicable assessment criteria - Multiple dwellings |
Partially fitted: This issue is not applicable Fully fitted: All criteria relevant to the building type and function apply. Refer to Appendix E – Applicability of BREEAM New Construction to single and multiple dwellings, partially and fully fitted for a more detailed description of residential assessment options. |
General | ||
CN3 |
Utility company energy monitoring equipment | Energy meters installed by a utility company that can provide the future homeowner or tenant with accurate and regular energy usage information per dwelling, can comply with this issue. |
CN3.1 |
Electricity is the primary fuel |
Where the primary fuel is electricity and current electricity consumption data are displayed to occupants through a compliant energy display device, which includes heating or cooling, two credits can be awarded. |
CN3.2 |
Community heating, cooling or solid fuel systems | If it is not possible to measure the energy consumption based on the incoming mains supply using a compliant energy display device, a heat meter is required to be installed to measure the heat energy. The heat meter must calculate the energy consumption in kilowatt hours (kWh) which can then be transmitted to a compliant energy display device. |
Evidence
Ref | Design stage | Post-construction stage |
---|---|---|
All |
Relevant section or clauses of the building specification or contract. Design drawings. |
BREEAM Assessor’s site inspection report and photographic evidence of the installed and functioning meter. |
Additional information
Relevant definitions
- Compliant energy display device
- This is a system comprising a self-charging sensor fixed to the incoming mains supply or supplies, to measure and transmit energy consumption data to a visual display unit in an accessible location. As a minimum the visual display unit must be capable of displaying the following information:
- Local time
- Current (real time) energy consumption (kilowatts and kilowatt hours)
- Current (real time) estimated emissions (g/kg CO₂)
- Current (real time) tariff
- Current (real time) cost (per hour)
- Visual presentation of data (i.e. non-numeric) to allow consumers to easily identify high and low levels of usage
- Historical consumption data so that consumers can compare their current and previous usage in a meaningful way. This should include cumulative consumption data in all of the following forms: day, week or month billing period. The data must be stored internally for a minimum of two years or be connected to a separate device with automatic upload from the energy display device.
- Primary fuel
- The fuel used to provide the majority of heating or cooling to the dwelling under assessment.
- Self-charging sensor
- A sensor or transmitter powered by the mains supply to the building that transmits energy consumption data to a visual display unit. Long-life batteries, with a minimum life expectancy of seven years, can be used in place of a self-charging sensor or transmitter where the functionality of the system is demonstrated to be maintained by the assessor.
