Arkinova is a technology hub dedicated to eco-building, bringing together young start-ups, R&D companies, architects and engineers. The Basque Country urban authorities wanted this building to be exemplary: the materials that were used have a low energy and carbon footprint, enabling the structure to be energy positive, suitable to tomorrow’s societal, technical and energy changes, while respecting the environment. Offices are modular and equipped with cutting-edge technologies (3D digital modelling).
The series of workshops organised by GRDF and the ADEME was an opportunity to mobilise more than fifty actors in planning and development to collectively reflect on these issues, target obstacles to action, identify courses of action and set priorities. This document summarises the main collaborative proposals put forward by the participants. The 9 proposals detailed here confirm that, despite emerging initiatives and best practices, expectations and needs persist.
The smart city and the digital transition are a way for urban planning agencies to rethink their philosophy of action, their missions and the evolution of their businesses to guide the transformation of the territories in they work. The National Federation of Urban Planning Agencies (FNAU) has therefore devoted a major part of its 2017-2018 action agency to developing digital technology. A survey of the urban planning agencies was conducted in early 2017 to better understand the actions and territorial strategies employed.
Sustainability was the core concept of this building, designed by EIFFAGE. This 19 000 square metre building benefits from high environmental performance, exceeding the 2020 eco-building standards. It is energy self-sufficient thanks to 26 000 square metres of photovoltaic panels and 35 geothermal probes buried 250 m underground. It is also well insulated (facing East-West to favour natural lighting, triple glazing, 22cm-thick layer of exterior insulation).
Massileo is a renewable energy production system designed by Optimal Solutions, a subsidiary of Dalkia (EDF Group). By recovering sea water calories using a warm water loop, this grid is able to simultaneously produce heating, air conditioning and domestic hot water, thanks to heat pumps. This 100% renewable local energy allows Marseille’s housing, offices and shops to trade their calories and to be as much a consumers as a producers of energy. An example of this is the Smartseille eco-district, where Massileo has been operational since 2017.
The city is a territory where infrastructures, equipment and urban services form an urban heritage at the disposal of its inhabitants. The Muse platform designed by Citelum, a subsidiary of the EDF Group, makes it possible to identify, locate and audit a city’s heritage for a better optimisation of its use. It is a collaborative platform that develops four axis:
Knowledge of city’s infrastructures: heritage inventory, creation of identification cards by equipment, geolocation and activity history.
Deltagreen is the only building in France that produces, stores and recovers electric power through a hydrogen station. Its photovoltaic fields not only enable it to be self-sufficient, but also to resell energy. Deltagreen is “Passiv Haus”-certified thanks to its energy performance and was also a 2018 Green Solution Awards winner.
This action handbook “Datacities: producing and managing urban data services of public interest” explores the changes in territorial governance modes induced by urban data services. It collectively develops proposals and contributes to empowerment of public actors on the issue of data territorial governance, so that they can take up action on major issues.
Digital technology has taken over cities, but not at all in the way the “smart city” scenario tells us. It has indeed deeply transformed the lives of city dwellers and the functioning of certain urban services, but it has done so without any existing strategic input from actors working in urban planning, particularly from public authorities. Through case study analysis, this project seeks to identify the collaboration challenges between new digital actors and traditional actors, notably local authorities .
Produced by Cap Digital at the end of 2016, this prospective report highlights a whole series of questions, concerning the disinterest of the citizens for the public thing, their mistrust toward those who embody it, resulting in low voter turnout and polarization towards extremes.
