# Energy 2.3 Electricity Consumption
# Applies to
All development types
# Objective
Ensure the efficient use of energy and to reduce consumption of electricity.
# Summary
Points are awarded when annual electricity consumption is >10% below the benchmark, as calculated by the in-built calculator or demonstrated via committed to deemed-to-satisfy criteria (non-residential only) or alternative modelling. The calculation uses both building fabric and building services inputs.
# Documentation & evidence required
- If using the DtS method, provide your insulation specifications (R-values), preliminary glazing calculation, heating and cooling system type and CoP/EER, and water heating system details.
- If you are providing your own calculations for non-residential, supply modelling assumptions and results. Ensure that methods meet the requirements of the NCC Verification Method JV3.
- If you are proposing an alternative energy modelling protocol, seek the approval from the relevant local council before proceeding.
- For all dwellings, show heating/cooling outdoor units (condensers), solar hot water panels and clotheslines on plans.
- If you are providing your own calculations for dwellings, supply modelling assumptions and results. Include energy and greenhouse emissions for heating, cooling, hot water and clothes drying, with calculations clearly shown.
