# 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%, as calculated by the built-in calculator, by commitment to deemed-to-satisfy criteria for non-residential, or demonstrated via alternative modelling. Peak demand is calculated based on the NatHERS cooling load figure for dwelllings 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
