Harnessing London’s underground heat and retrofitting NYC – EI Energy Efficiency conference
Big city energy management challenges from both sides of the pond were discussed at EI’s annual Energy Efficiency Conference this week in London.
Transport for London’s Senior Energy Strategy Manager Alex Gilbert provided an insight into a transit system expected to spend £6 billion on energy by 2030. The organisation’s strategy for managing energy in its housing and transport portfolio focusses on 4 areas – efficiency, generation, procurement and road transport electrification. Alex outlined hopes that more waste heat in the London underground system could in future be harnessed. At present, nearly 80% of heat is simply absorbed by the tunnel walls.
And, providing a New York perspective, Ali Levine, former Senior Policy Advisor at NYC Mayor’s Office of Sustainability briefed delegates on work underway in the city to reduce energy use and emissions by retrofitting existing buildings. She outlined pathways based on deep energy retrofit showing that 40-60% energy reductions are possible using existing technologies and strategies.
The conference also tackled the energy and carbon reporting requirements facing UK businesses and organisations this year, in particular phase 2 of ESOS (Energy Savings Opportunity Scheme) and SECR (Streamlined Energy and Carbon Reporting). Emily Chapple, Head of Sustainability at CBRE, Neil Guthrie, Principle Technical Officer at the Environment Agency and Lucy Hayes MEI, Principle Energy Professional at Jacobs discussed lessons that have been learned from ESOS Phase 1 including the need for organisations to start preparations earlier and improvement in the auditing of transport energy use, which Neil described as having been ‘weak’.
