Energy budget
In the built environment, the term 'energy' is typically used in the context of generating heat, powering equipment, creating products and materials, transportation, and so on.
An energy budget is a specific target for Energy Use Intensity (EUI) that must not by exceeded, where Energy Use Intensity is an annual measure of the total energy consumed in a building. Ref Climate Emergency Design Guide: How new buildings can meet UK climate change targets, published by the London Energy Transformation Initiative (LETI) in January 2020.

Comments
[edit] It would be good to define the scope of EUI and whether renewables are or are not included. LETI's definition within the Climate Emergency Design Guide excludes energy consumption from on-site renewable energy generation which differs from RIBA's Operational Energy targets which include energy consumption from renewable energy generation and LETI's subsequent FAQs on Net Zero. There is risk of relying solely on metrics which exclude on-site renewable generation as it can mask the poor performance of building fabric and operation.
