The Need and Challenge of Ambitious Climate-Energy Strategies at the Urban Scale

Abstract : This event, coordinated by Nadia Maïzi, MINES ParisTech, focused on the design of climate-friendly strategies for cities to address climate change vulnerability and promote sustainability. Presenters introduced concrete initiatives, including from academia, local authorities and industry. On the technological tools to visualize a climate-impacted future, Maïzi emphasized the importance of having scenarios that do not solely rely on prediction, but also on identifying solutions. She stressed the need to develop environmental goals through involving the different sectors of society, including industry, local governance systems and research. Edi Assoumou, MINES ParisTech, presented on simulating alternative 2050 urban energy strategies, using the city of Bologna as a case study. On the available modeling tools, he identified analytical and numerical models, and called for: an emphasis on transport network analyses; integration of local renewables; and detailed building models. On exploring potential 2050-pathways, he proposed simulating long-term strategies, including through: energy consumption mapping; driving useful energy needs to address future energy service levels; and anticipating technological changes and altered external choices. On the potential range that the research explored, he noted: combining multiple dimensions; the scale of population uncertainty at the urban level by 2050; and achievable mitigation thresholds. Vincent Mazauric, Schneider Electric, presented on the role of energy management in empowering “wiser” cities. He noted that global energy consumption will double in the next 40 years and electricity consumption will double in the next 20 years, but said that in new economies driven by urbanization, this will occur in just a decade. On the essential steps to addressing these challenges, he urged: constructing flexible buildings that can adapt to an uncertain future; introducing the holistic view of the district; and moving towards an energy-positive district through rebalancing its energy mix. During discussions, participants posed questions on ways to include behavioral change within society in modeling initiatives; and the energy consumption trade-offs between different sectors.
