Cooling is business

• 10 of electricity used for cooling (global)
• 80 cooling in USA and Japan (commercial and
  institutional)
• lt 50 in EU, but expanding rapidly
• About 40-50 is process cooling (i.e. computer)

6
District Cooling

• Centralized cooling production
• Distribution grid
• Different customers
• Energy service

Europes perspective
Environment/ Kyoto
Security of supply
Free market/ competition

Environment / Kyoto Protocol

• Centralizing Cooling production is energy
  efficient
• Use of sustainable sources (i.e. free cooling)
• Use of process-optimization (combining efficient
  technologies)
• Savings approx 1-2 of the electricity
  consumption
• Local benefits
• Enhanced aesthetics
• Abandoning noise from rooftop chillers
• No local temperature rise

Free energy Market / Competition

• DC is an innovative solution
• DC competes freely with alternatives
• DC is established without subsidies
• Customers choose their own tailored solution
• New energy service in a competing market

What is necessary?

• Create a level-playing field for competition
  between individual and collective systems (green
  certificates, CO2-trading, subsidies and taxes)
• Take District Cooling into consideration in
• Energy Efficiency of Buildings Directive
• Energy End-use Efficiency and Service Directive
• Security of Supply Infrastructure Directive
