Cooling and Heat Re-Use

Cooling by sea water
  • Cool sea water available from basin near the sea shore.
  • Sea water stays reasonably cool also in summer. Thus high free cooling energy share

Excellent conditions for air cooling
  • Cold climate
  • Cooling by cooling towers or direct air cooling
  • Energy re-use in planned local DH-network
