# Energy 2.2 Peak Demand
# Applies to
All development types
# Objective
To reduce demand on electrical infrastructure during peak cooling periods.
# Summary
Points are awarded when the instantaneous (peak-hour) cooling demand has been reduced by >25% for dwellings or meeting the benchmark for non-residential spaces, as calculated by the built-in calculator, demonstrated by commitment to deemed-to-satisfy criteria (non-residential only) or demonstrated via alternative modelling. Peak demand is calculated based on the NatHERS cooling load figure for dwellings and JV3 modelling (including cooling system) or NCC comparison for non-residential. Reducing cooling loads (via measures such as improved insulation, glazing and shading) will deliver an improvement in the peak cooling demand.
# Documentaion & evidence required
- Preliminary NatHERS rating for dwellings
- JV3 modelling
- Own calculations
