# Operational Energy 1.1 Thermal Performance Rating - Non-Residential
# Applies to
Non-residential developments
# Objective
Reduce energy needed to achieve thermal comfort in summer and winter - improving comfort, reducing greenhouse gas emissions, energy consumption, and maintenance costs.
# Summary
Points are awarded when the building's thermal fabric reduces heating and cooling energy consumption to meet the reference case (NCC2022 Section J). This is demonstrated by commitment to deemed-to-satisfy criteria or heating and cooling energy consumption calculated from energy modelling results, which includes both building fabric and building services inputs.
More points are awarded for every % improvement including the following:
- 0% reduction - 12.5% score
- 10% reduction - 37.5%
- 20% reduction - 50%
- 60% reduction - 100%
# Documentation & evidence required
- If using the DtS method, provide your insulation specifications (R-values), preliminary facade calculation, heating and cooling system type and CoP/EER, and water heating system details.
- If you are providing your own calculations, supply modelling assumptions and results. Ensure that methods meet the requirements of the NCC Verification Method JV3 and BESS requirements.
- If you are proposing an alternative energy modelling protocol, seek approval from the relevant local council before proceeding.
