Second Interregional Event in Paris
On the 22nd and 23rd of November, the Paris Climate Agency has greeted the partners of the MonitorEE project for the second Interregional Event.
The first day took place within the City Council of Paris. It started with the presentation of the energy situation in Paris and its Policy instrument, Paris Climate Plan, to implement ecological transition and the hosting agency. Then, through a master class, the Paris Climate Agency presented its two main tools:
- CoachCopro, a web platform dedicated to the information, accompanying and the follow up of retrofit projects.
- EnerSIG, a mapping application that offers cross-data about buildings characterization, energy consumption and potentials, developed with the Local Authority and the Paris Urbanism Agency
The morning session ended with a best practices workshop, allowing each partner to present a local and innovative project related to monitoring.
The afternoon session was dedicated to the steering committee first and second to the study visit of the City Council. During this first visit, the Local Authority presented the energy supervision of public buildings, the smart heating controlling system and showed the boiler room. According to the Paris Climate Plan aiming at reducing energy consumption and phasing out fossil fuel, the Local Authority developed several initiatives to develop more renewable energies and reduce its energy consumption. On the City Council, a huge historical monument, provided by the heat network of Paris, the Local Authority has recently installed monitoring tools, wireless temperature sensors to reduce energy consumption and improve energy efficiency.
The second day was specifically dedicated to study visits. In the morning, we visited one of the biggest urban projects led in Paris the last years, the eco district Clichy-Batignolles.
This project, planned by the City of Paris and the Metropolis embodies the decision of the Local Authority to build a more sustainable city. It is indeed a good study case that tackles many innovative aspects. Designed by the architect François Grether and the landscaper Jacqueline Osty, the Eco district was built on a French rail network brownfield between 2002 and today. The project emphasizes the functional and social diversity in a new urban and green area. The first issue was to combine architectural quality and sustainability. The Eco district was built according to a bioclimatic conception, developed renewable energies, a rich biodiversity, and an automated vacuum waste collection system. It also determined an ambitious strategy in terms of energy efficiency and low carbon emissions that was notably improved by the implementation of a specific service dedicated to the monitoring through the European project CoRDEES.
Some key figures that highlight this ambition : 85% of heating and hot water are provided by hot water are provided by geothermal system and supported by the Paris heat network if necessary and 40% of electricity is provided by the photovoltaic solar panels. In the afternoon, we visited two condominiums which were awarded for the ambitious energy retrofit works they realised.Both condominiums installed a predictive and controlling heating system, developed by Efficap and based on inside and outside temperature sensors, forecast, location, sun exposure and building inertia. This innovative technology was presented by one of the founders of Efficap. During the visits, we visited the boiler room with the installation of this system. Both condominiums realised satisfying energy savings and gained thermal comfort. They consider going further in the retrofit installing solar panels or greening some parts of the buildings for instance. Eventually, these condominiums received subsidies to finance their retrofit project, coming from the State, the Local Authority or Energy savings Contract.
