2. Suggesting the most appropriate local energy mix. The specific energy mix put forward in the team’s proposal enables a limited use of carbon-heavy centralised production (coal) and, at the same time, a better use of local renewable energy.

3. Designing the local energy system. The energy system designed by the team spatially coupled heating and cooling networks with specifically sized energy centres. It was conceived to optimise efficiency and allow for the solution’s easy scaling to the 42 km² Comprehensive Zone, during the next phase of construction.

By placing energy in the early stage of urban design, EDF has shown that it is possible to conceive a distributed low-carbon

energy system matching Lingang’s specific local challenges, using technologically mature and economically viable solutions. Thanks to this innovative approach, the Sino-French team made up of EDF, Tongji UPDI and l’AUC won the 1st place in the city’s urban conceptual design competition in November 2014.

Context & stakes The Lingang District is one of Shanghai’s nine satellite towns, located 70 km South-East of the city’s centre. The initial development of this green-field site will be started on a 1 km2 section, then to be extended to a larger Comprehensive Zone of 42 km2.In order to obtain innovative green urban design proposals for this New Comprehensive Zone, real-estate developers launched an International Competition of Conceptual Urban Design, in July 2014.

EDF’s added-valueBy taking into account energy at the earliest stages of urban planning and by using systemic approaches, EDF and its partners were able to put forward a radically new low-carbon and energy efficient urban solution.The proposed solution needed to address two specific local energy chal-lenges: (1) CO2 emissions reduction and (2) energy demand optimisation.

Integrating an energy planning in the early phase of urban design has never been brought up before in China. For this outstanding proposal, the energy planning is its most original and innovative part. madame wang Jingxia, president of the jury and former president of CAUPD (China Academy of Urban Planning Design)

Three steps structured EDF’s approach:1. Reducing energy demand (electricity – heat – cold). A cooperative urban design with Tongji UPDI and l’AUC allowed the team to come up with a low-energy solution, leveraging mix space use and higher urban density. Moreover, while following Chinese “Green Building” standards, new technologies reducing thermal losses and promoting heat recovery were also incorporated into the proposal which greatly improved global energy efficiency in regards to building heating and cooling.
