The La Confluence construction site in Lyon, Rhône-Alpes, France

The sustainable urban project of the La Confluence neighborhood in Lyon is developing thanks to the help of Japanese technologies implemented as part of an agreement with the NEDO (New Energy and Industrial Technology Development Organization). From Hikari, the first energy positive mixed block to the renewal of Perrache, here is a review of the progress of these operations.

The product of an agreement signed in December 2011, between the Urban Community of Lyon and NEDO, the demonstrator project “Lyon Smart Community” is taking form. It will contribute to the sustainable development of the La Confluence urban building project. The project is based on four separate parts: the first being the construction of Hikari, a block of energy positive housing and office buildings. Secondly, there will be a deployment of a shared group of electric vehicles to be fueled primarily by energy produced from photovoltaic panels installed on the tops of certain buildings. Thirdly, the distribution of ConsoTab, a tablet allowing for the viewing of residential energy consumption, and finally the implementation of this monitoring tool which tracks energy production and consumption for the entire La Confluence neighborhood.

Currently in the structural building phase, the block named Hikari was designed by the Japanese architect Kengo Kuma, under the contractor Bouygues Immobilier/SLC. It will be the first energy positive mixed block. Amounting to 12,000m2, this grouping (containing offices, businesses, and housing) enjoys a bioclimatic design and the buildings’ parameters will be centrally controlled. This will enable precise regulation of heating and cooling by using intermittent energy surpluses.

Residential Energy Monitoring

Before the vast program of energy reworking that GrandLyon Habitat will conduct on the 275 public housing units in the neighborhood of Perrache, in the beginning of 2015, monitoring tablets for viewing energy consumption were issued to 206 resident volunteers as part of the “Lyon Smart Community” experiment.

The ConsoTab, developed by Toshiba, will allow for real time monitoring of water, gas, and electricity consumption translated into euro. This is made possible through installing adapters on different meters capable of gathering user data. The participating residents are individually instructed on how to use the tablet, and eventually, to better regulate their consumption habits and reduce expenses.

Renewal work on the buildings will be based primarily on thermal isolation, carpentry changes, and modernizing the heating system. The intended goal is to go from an average consumption of about 290kWh/m2 a year to less than 80kwh/m2, resulting in an energy consumption reduction of 70%.
