  • Boardwalk :

    A construction that may be likened to a bridge or a viaduct, the key characteristic of which is that it is long and relatively low.

  • Cogeneration :

    The principle of simultaneously producing two different energies from the same process. The most common form of this is the production of heat and electricity.

  • Concerto :

    A programme run by the European Commission to encourage the construction of energy efficient buildings. In 2004, the Confluence district was awarded funding for the implementation of this programme in units A, B and C near the marina (Place Nautique).

  • Consultation :

    A policy of consulting the people likely to be affected by a decision before it is taken. In urban planning, this consists of putting a developer’s plans forward for scrutiny by local residents, people who frequent the area and associations. In Confluence, this consultation is performed upstream of any development: we ask all local stakeholders for their opinions before formulating a proposal.

  • FRAPNA :

    The Rhone Alpes Federation for Nature Protection

  • Hikari :

    The name of the project located on the corner of the marina (Place Nautique) and Cours Charlemagne. It means “Light” in Japanese. This trio of buildings was designed by the architect Kengo Kuma to allow maximum light to enter. The building also produces more energy than it consumes.

  • HQE :

    High Environmental Quality. A standard aimed at controlling the environmental impact of buildings on their environment by improving energy performance, reducing pollutant emissions and reducing waste production.

  • Metropolitan Area : A group of adjacent towns made up of an urban centre and outlying towns, whose active population works in the urban centre or surrounding towns. There are approximately 400 metropolitan areas in France. According to the national statistics agency, in 2010, the Lyon area had a population of 2,142,732, making it the second largest urban area in France, after Paris.
  • MIN :

    A Market of National Interest (MIN), also known as a wholesale market, is a market for professionals only. They are always located near major roads and large cities. Lyon’s own MIN was established in 1961 between Rue Casimir Perier and Cours Charlemagne. It was moved to the town of Corbas in January 2008, freeing up approximately 20 hectares, which make up most of the ZAC 2 special development zone.

  • Mutualisation :

    The distribution of the use of equipment and assets between different groups of individuals. Mutualisation is different from sharing insofar as it allows each group to benefit from the assets or equipment in their entirety, by defining ‘time share’ systems. At Confluence, mutualisation is a principle that concerns in particular two car parks shared between different users (employees, inhabitants, visitors, shopkeepers etc.)

  • NEDO :

    Japan’s New Energy and Industrial Development Organisation. This para-governmental agency, the equivalent of France’s Ademe (Environmental and Energy Management Agency), participates in various projects at Confluence (block P, energy boxes etc.).

  • NET FLOOR AREA :

    This corresponds to the total floor area on each floor excluding uninhabitable spaces (cellars, attics, balconies etc.) The first development phase of Confluence reached a net floor area of 400,000 sq. m, and the second phase 420,000 sq. m.

  • Photovoltaic :

    A system that harnesses the sun’s energy in the form of photons (physical particle) and transforms it into energy.

  • PLAI :

    The Prêt Locatif Aidé d’intégration is a social housing loan for people in financial difficulty. It is available to people who earn 55-60% less than the income cap set for social housing tenants.

  • Plan climat :

    In light of climate change, Greater Lyon has made both national and international commitments. By 2020, it aims to reduce greenhouse gas (GHG) emissions by 20% and to ensure that 20% of the region’s total energy consumption is renewable. By 2050, GHG emissions could be a quarter of what they are now.

  • PLI : The Prêt Locatif Intermédiaire is a social housing loan available to people whose income is above the social housing income cap but not enough to enable them to access private housing in big cities. The income cap set for a PLI generally corresponds to 1.5 times that of social housing.
  • PLS :

    The Prêt Locatif Social is a social housing loan. Rents are capped and set according to geographical location. The PLS are for people whose income is below a certain amount. The investor can thus lease his property to a tenant with an income up to 30% higher than the cap on conventional social housing.

  • PLUS :

    The Prêt Locatif à Usage Social is a social housing loan intended for social housing organizations (HLM) and semi-public companies (SEM). Operations financed by the PLUS mechanism must accommodate at least 30% of tenants whose incomes fall below 60% of the cap and 10% of tenants whose incomes are 20% above the cap, in order for the social housing provided to be accessible to 75% of the population.

  • Public space :

    Term given to denote all spaces where the public passes or gathers. This may include roads (streets, boulevards and avenues), squares, public or private gardens and they may be surfaced or planted, depending on the location: green courtyards, green streets, aquatic gardens, or ‘mineral’ gardens.

  • Soil sealing :

    Excessive sealing of the ground in urban areas (by building roads and car parks etc.) creates artificial drainage paths and prevents the ground from naturally absorbing excess water. By reducing this effect, we can prevent the risk of flooding.

  • SPL :

    Initially a Semi-Public Company (SEM), then a Local Public Development Company (SPL) and finally a Local Public Company, Lyon Confluence is continuing the same development work, i.e. handling project studies and real estate acquisitions; commissioning projects to develop public spaces, selling land to private promoters, coordinating work sites, and overseeing the consultation and communication related to the development work.

  • Underpass : A short tunnel enabling one road to pass under another.
  • Urban hub :

    An area that offers a minimum of 5000 jobs and which does not overlap with other urban centres.

  • Water meadow :

    A wide but shallow vegetated ditch that temporarily collects water either to evacuate it via an overflow channel, or to evaporate it (evapotranspiration), or to absorb it. 

  • WWF : World Wildlife Fund.  The world’s #1 conservation organisation with 5 million donors worldwide and an operational network in 100 countries. It runs 1200 conservation programs around the world.
  • ZAC :

    A Zone d’aménagement concerté is a delineated development zone wherein all types of operations are carried out in coordination: housing, public spaces, roads, transport, economic development, local amenities.
