报告人简介：Dr Lirong Liu is a Senior Lecturer in the Centre for Environment and Sustainability (CES) at University of Surrey. She is also appointed as AI Fellow at Surrey Institute for People-Centred Artificial Intelligence, Fellow of Institute for Sustainability, and the Lead Researcher of Eco-Shaper (https://eco-shaper.com/). She has recognized expertise in innovatively integrating methodologies at different scales to address scientific issues with consideration of conflicting environmental, social and economic objectives. She is the UK PI in the project ‘Wellbeing, inclusion, sustainability and the economy’ (€3m, Horizon Europe), leading the sustainable wellbeing economy research. She is a Co-I of the ‘Soilless cultivation for rapid bioenergy feedstock production’ project (£4m, BEIS) on socio-economic impacts assessment and is Co-I of the Energy Demand Research Centre (£18.75m, UKRI) bid working on the Equity theme. She is involved in the UK Energy Research Centre (UKERC) and Network+ Decarbonisation of Heating and Cooling (H+C Network) by leading flexible funds as PI. Her research also received support from surrey internal funding and Royal Society.

报告内容: Residential heating displays huge decarbonisation potential towards Net-Zero. The complexity of heating system and socio-economic system appeals for a systematic design to avoid exacerbating fuel poverty. This study develops a whole system approach which integrates building stocks analysis, distributed heating system optimisation, economic and environmental impacts simulation, with application to the UK. Results show that investment in heating system could stimulate the greenhouse gas emission of whole supply chain, hedging the emission reduction achieved in heating system. Electricity decarbonisation plays a vital role in achieving whole system emission reduction. Optimised heating system decarbonisation plan heavily relies on future energy prices. In the case study, only air source heat pumps are chosen when electricity price is lower than 3 times gas price. The whole system approach developed in this study is shown to be a powerful decision support tool that can help conceive heating decarbonisation strategies for wider regions and countries.
