# 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
