Located in the Confluence district, the Lyon Smart Community aims to be a positive-energy eco-neighbourhood that will comprise a series of positive-energy buildings. It aims to relieve traffic congestion in the city and shrink the carbon footprint of urban travel via the use of electric cars. Inhabitants will also be helped to limit energy consumption. Lastly, data will be gathered, collated and analysed using a Community Energy Management System designed to provide comprehensive energy management and monitoring.
The main stakeholders in the project, Toshiba (overseeing technological implementation), Bouygues Immobilier, Veolia Transdev (via its subsidiary Proxiway) and the Greater Lyon Housing Office, are part of a business ecosystem totalling 30 partners working hand in hand with the Greater Lyon urban authority and Nedo to map out the transition towards a smarter, more sustainable city for everyone. This is the purpose of the Lyon Smart Community pilot project.
In this context, Bouygues Immobilier has teamed up with SLC Pitance, architect firm Kengo Kuma & Associates and CRB to build Hikari (meaning "light" in Japanese), a complex of three mixed-use buildings totalling 13,000 m2 and comprising the following:
2 office buildings (Higashi and Nishi): 8,000m² - 550 workstations
36 housing units (Minami + 4 penthouses at the top of the Nishi building)
100 car parking spaces
Hikari is at the heart of the Lyon Smart Community pilot site, setting the standard for energy efficiency and in the use of renewable energy sources.
Bioclimatic architectural design and a systematic endeavour to achieve low energy consumption will enable the project to meet its targets in terms of energy and environmental performance.
For example, optimal use is made of natural light. Energy production will mainly stem from a vegetable oil cogenerator, and from photovoltaic panels — with the three buildings sharing the same power source. By having offices, homes and shops on the same premises, energy-demand peaks can be avoided.
An innovative Franco-Japanese industrial partnership (with Nedo and Toshiba) has been set up to guarantee the energy performance of the block.
"The expertise built up by Bouygues Immobilier in designing positive-energy buildings, ahead of the future RT2020 thermal regulation, means that we can apply our expertise to a whole block today and to a whole neighbourhood tomorrow. Working in conjunction with Kengo Kuma, we have left no stone unturned in our analysis of bioclimatic issues (…) The whole of the Hikari development is expected to produce ‑ through co-generation and photovoltaic plants ‑ a total of 1,200 MWh in primary energy, equating to 465 MWh of power for final consumption, i.e. that used by all the electrical equipment (household appliances, computers, TVs, etc.) in 160 households," stated Eric Mazoyer, Deputy CEO of Bouygues Immobilier.
Construction work will start in the spring of 2013.
