Title: District Cooling


1
District Cooling
  • a Sustainable Response
  • to Europe's Rising Cooling Demands

Content
  • Why District Cooling?
  • What is District Cooling?
  • Europes perspective
  • What to do?

3
Cooling is a must
4
Cooling is a must
5
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

7
Where DC projects are
Existing DC projects
DC projects under construction
DC projects in study
8
Europes perspective
Environment/ Kyoto
Security of supply
Free market/ competition
9
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

10
Security of supply
11
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

Free market/ competition
13
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
