Buildings could be prioritised for a Decarbonisation Options Assessment if they have a higher than average industry or estate energy/carbon benchmark. Alternatively, buildings could be prioritised if they have energy sources that will not benefit from National Grid Decarbonisation (which will result in reduced carbon emissions associated with electricity generation), such as natural gas, fuels, other. For more information on National Grid Decarbonisation refer to sections 7.7 and 7.14.3.

In addition to the above processes for prioritisation, due consideration should be given for buildings that may be part occupied or controlled by other parties (i.e. additional occupiers). In these instances, additional information ought to be collected on how the buildings' energy and carbon performance is impacted by the Authority's own emissions, versus those that other organisations are accountable for e.g. third-party developments on hospital sites, typically, catering facilities, retail outlets, charitable organisation and other third sector organisations. In these cases, this should also be input into the Decarbonisation Options Assessment process as part of the evaluation of decarbonisation options (see section 7.14).
