Energy category
The ENE category, in terms of points, is the most important BREEAM category. This section acknowledges the measures taken that improve the inherent energy efficiency of a project. It encourages the reduction of carbon emissions and supports efficient energy management throughout the design and operational phases of the project.
ENE1 – Reduction of energy use and carbon emissions – max 13 credits AIM - To recognize and encourage buildings designed to minimize operational energy demand, primary energy consumption, and CO₂ emissions.
Assessment criteria:
Calculate energy performance Ratio for New Construction (EPR NC) and compare with benchmarks
ABB Smart Buildings Solutions
* Applicable for devices that can switch/control energy flow, and thus have an impact on the energy consumption of the building
ENE2 – Energy monitoring – max 2 credits AIM - To encourage the installation of energy sub-metering to allow monitoring of operational energy consumption. To allow managers and consultants post-handover to compare actual performance with targets in order to inform ongoing management and reduce any performance gap.
Assessment criteria:
Sub-metering by end-use:
- Where the total consumption of any single end-use category is estimated to account for more than 10% of the annual energy consumption for a given fuel type, it is necessary for this end-use to be sub-metered
Sub-metering by functional or tenanted areas:
- In most circumstances, sub-metering should be per floor, or per floor plate where there are multiple service risers, cores, or floor plates
ABB Smart Buildings Solutions
(*) Applicable for devices that can monitor
ENE3 – External Lighting – max 1 credit AIM - To recognize and encourage the specification of energy efficient light fittings for external areas of the development
Assessment criteria:
All external light fittings are automatically controlled for prevention of operation during daylight hours
ABB Smart Buildings Solutions
(*) Applicable for devices that can switch external lighting
(**) All Metering products (except CMS and EV meters) have digital outputs that can act for controlling an on/off switch, Control can be carried out by timers (AG timers, DBT timers) and by twilight switches (TL line). Dimming is not possible.
