  3. 3. Cities – a challenge and opportunities• World population is growing• More want to live in cities• It will be a challenge, but also• An opportunity to create smart energy solutions• The EU has taken the lead promoting Smart Cities with smart grids for • Electricity • District heating • District cooling and • Gas Smart Energy Cities by Anders Dyrelund March 20 2012 3
  4. 4. The overall energy policy objectives in EU• Reduce the fossil fuel consumption • For security of supply and • For climate reasons• In a cost effective way in order • To be competitive • To secure welfare and sustainability for next generationsWe do this in the most sustainable way • Minimizing life-cycle costs including environmental costs and • Minimizing long-term costs for the local community Smart Energy Cities by Anders Dyrelund March 20 2012 4
  5. 5. EU legislation to implement Energy Policy • Strategic environmental assessment Directive • Co-operation cross sectors • Energy Performance of Buildings Directive • Good indoor climate • Cost effectiveness • Local conditions • Low carbon (nearly zero), taking into account – RES via District heating and cooling, DH&C – CHP via District heating and cooling, DH&C – Heat pumps – Local RES – Optimal building envelope Smart Energy Cities by Anders Dyrelund March 20 2012 5
  6. 6. EU legislation to implement Energy Policy (2) • Renewable Energy Directive • Urban planning of heating and cooling infrastructure • Nearly Zero buildings taking into account RES via DH&C • Energy Efficiency Directive (as drafted) • New power plants to be CHP located near heat markets • Urban planning of heating and cooling infrastructure • Nearly Zero buildings taking into account CHP via DH&C • ECO Directive How to use and stimulate energy efficient appliances • Low energy electronics • Standard for 12V DC for low energy energy electronics • Hot tap water to laundry and dish washing not in labelling Smart Energy Cities by Anders Dyrelund March 20 2012 6
  7. 7. Most important objectives in the energy policy in Denmark since 1976• Objectives since 1976 • Cost effectiveness • CHP • Reduce dependency on oil• New additional objectives • To be independent of fossil fuels in 2050 • The challenge will be to do it in a cost effective way Smart Energy Cities by Anders Dyrelund March 20 2012 7
  8. 8. Important Danish legislation35 years of experience has inspired EU • Electricity supply act from 1976 • all new power capacity since 1976 has been CHP • Heat supply act from 1979 • Urban planning of heating infrastructure • More CHP • More RES (in particular waste to energy) • District cooling act • New, but insufficient • New building code • In contradiction with EU directives and Heat supply act • Also other countries have problems to implement the directive Smart Energy Cities by Anders Dyrelund March 20 2012 8
  9. 9. The Ramboll Smart Energy City Concept Smart Intelligent Grids and Buildings• National power grid and a dynamic electricity market• City-wide district heating grid • storage optimal use of CHP and RES• City district cooling grid • storage and optimal free cooling• National natural gas - biogas grid • gas storage, • gas to CHP and small houses• Buildings • Optimized building envelope • Low temperature heating • High temperature cooling • Micro DC grid for micro electronics Klimakommissionen • Adjust cosumption to price signals and control (”smart grid”) Smart Energy Cities by Anders Dyrelund March 20 2012 9
