International Energy Agency Implementing Agreement on District Heating and Cooling including Combined Heat and Power
What is IEA-DHC?
International Energy Agency (IEA)
• was established in 1974
• works to ensure reliable, affordable and clean energy.
The District Heating & Cooling (DHC) ‘implementing agreement’
• aims to improve the design, performance and operation of district heating systems
• current members: Canada, Denmark, Finland, Germany, Korea, Norway, Sweden, UK, USA.

We are 30!
• There was a meeting (in Stockholm!) in October 1983…
• As a result of which the District Heating ‘implementing agreement was established…
• And the first ‘Annex’ commenced 1984
• Each Annex is a three year period comprising a group of projects
• The completion of Annex X…
• 10 x 3 = 30 years!

IEA-DHC: what do we do?
• Carry out research projects on all aspects of DHC technology focusing on reducing cost and improving performance:
• eg pipe materials, installation techniques, system optimisation, pro-active maintenance, thermal storage, integrating renewables
• Approximately 80% of projects are technically focused’; 20% policy focused
• Reports are produced for all projects and are available at the website: www.iea-dhc.org

Exciting times for district heating
• Recognition at IEA Secretariat: CHP/DHC Collaborative
• Recognition at European Commission: extensive project work now within research programmes: 10 years ago almost nothing
• Recognition at UN level: ‘District Energy in Cities: Unlocking the Full Potential of Energy Efficiency and Renewable Energy’ due 2015
• UK has established a Heat Networks Delivery Unit, and is funding feasibility work in more than 50 towns and cities.

But challenging ones – we need the international research
• Buildings becoming more energy efficient => diminishing heat demand; – issue for DH providers but needs to be part of an overall community solution
• Reducing temperature supply => lower heat losses; increased efficiency; more potential for renewables and surplus energy
• Future integrated infrastructure for sustainable cities; smart systems
• How to establish networks in embryonic markets – challenge for business models.

IEA-DHC projects – Annex X (2011-4)
• ‘Towards 4th generation district heating (4GDH): experiences with and potential of low temperature district heating case studies’
• ‘Economic and design optimisation in integrating renewable energy and waste heat with district energy systems’
• ‘Improved maintenance strategies for district heating pipelines’
• ‘Calculation tool for primary energy factors in DHC systems.’
These projects have concluded; reports at www.iea-dhc.org

Low Temperature District Heating for Future Energy Systems – a Task Sharing Initiative
• Amplifies the work of the existing 4GDH project
• Fundamental link between low temperature systems, integration of renewables, thermal storage, heat demands of future buildings…
• … all of which together imply the need for research areas on Methods & Planning Tools; DHC Technologies; Communities and Interfaces
