A year has passed since the GLA launched the original District Heating Manual for London and the industry has continued to develop through the efforts of utilities, institutions, government programmes, local authorities, commercial entities and other stakeholders committed to the development of decentralised energy infrastructure in London. Reflecting trends in the industry, the Manual has been launched with the new title ‘London Heat Network Manual’.
This year the Manual contains additional technical guidance in respect to control of heat networks, low return temperatures, low grade heat networks, building network design and control, thermal storage design and the carbon intensity of heat sources.
A key new feature in this edition is guidance on the role of Special Purpose Vehicles, in the commercial development of major decentralised energy systems in London at scale.
Finally, the Manual has been updated to reflect developments in the London Plan and the latest planning guidance.
