Press Release

Demonstration of Positive Energy Building Begins in Lyon, France

-Aiming for Wide Dissemination of Smart Community Demonstration Results-
September  18,2015
New Energy and Industrial Technology Development Organization (NEDO)

As part of the smart community demonstration project being conducted in Lyon, France, NEDO has started the demonstration of the positive energy building HIKARI (“Light”), which produces energy in excess of the amount consumed by the building. Such performance was made possible through the introduction of PV power generation, storage batteries, and heat storage materials that are controlled by an energy management system.

As France has set a goal of making all new public buildings constructed positive energy buildings, NEDO is aiming to disseminate the results of the demonstration widely in other cities and countries.

1.Overview

In order to achieve a community with sustainability and a high level of energy efficiency, in addition to promoting the introduction of renewable energy from a supply perspective, it is critical to consider the amount of consumption at every level from the city as a whole to buildings to individual households and to develop mechanisms to promote efficient use. It is also necessary to create smart urban infrastructure from a variety of perspectives, such as energy supply and demand and urban transit. Furthermore, in addition to developing new communities, promoting a smart city infrastructure in existing historical urban areas is necessary.

In Lyon, the Metropolis of Lyon (Grand Lyon) is promoting a redevelopment project in the Lyon Confluence and NEDO has been carrying out a smart community demonstration project in the area with Grand Lyon since 2011.

NEDO recently started the demonstration of the positive energy building HIKARI (Light), which produces energy in excess of the amount consumed by the building. Such performance was made possible through the introduction of PV power generation, storage batteries, and heat storage materials that are controlled by an energy management system. One of France’s leading construction companies, Bouygues S.A., was responsible for building construction.

As France has set a goal of making all new public buildings constructed positive energy buildings, NEDO is aiming to disseminate the results of the demonstration widely in other cities and countries.

2.Smart Community Demonstration Project in the Lyon Redevelopment Area

NEDO’s smart community project plays a key role in Grand Lyon’s urban redevelopment efforts. The plan is to conduct demonstrations based on four tasks with the aim of making the entire city of Lyon smarter through broad utilization of Japan’s advanced technology. This smart community demonstration project is NEDO’s first initiative targeting actual city-wide infrastructure.

NEDO’s Smart Community Demonstration Project in Lyon consists of the four tasks shown below. Tasks 2, 3 and 4 have already started, and with the commencement of the Task 1 demonstration, all four tasks are now being implemented.

  • Task 1: Construction of a positive energy building (PEB) that produces more energy than it consumes through the active introduction of renewable energy and storage batteries.
  • Task 2: Introduction of an electric vehicle (EV) management system and an EV car-sharing system that utilizes PV power generation.
  • Task 3: Promotion of energy saving behavior among residents through “visualization” of energy consumption in existing households (ConsoTab).
  • Task 4: Development of a community management system (CMS) that compiles energy information collected in Tasks 1, 2, and 3 and provides indicators used by the entire community.

3.Operation Commencement Ceremony

At the operation commencement ceremony, Executive Director Hiroshi Kuniyoshi of NEDO and representatives of Toshiba Corporation, NEDO’s entrusted company for the project, and other partner companies attended on behalf of Japan. From the French side, approximately 300 people attended, including Mr. Gérard Collomb, President of the Metropolis of Lyon, and Mr. François Bertière, Chairman and CEO of Bouygues Immobilier, which was responsible for constructing HIKARI. Representatives from other stakeholder organizations and companies as well as local residents participating in the project also attended the commencement ceremony.
