Nishi is one of the 3 buildings that make up the Hikari block of the confluence district in Lyon. On the edge of the Place Nautique, facing the Saône, the building with an area of 2246 m² of offices on 5 levels houses 4 roof villas, exceptional residences, which take place on the last two levels.

Owner approach of sustainability
The project is fully in line with Lyon Confluence's sustainable development policy, in line with the 5 axes of Agenda 21 in Lyon and meets the very high energy performance level set by the specifications: it must be BEPOS all-purpose considered. Designing a positive energy building in a densely populated urban area, on the block scale and not in the neighborhood, is a challenge that is essentially addressed by: • an architecture favoring the implementation of passive devices • maximum use of renewable energies present in situ • the judicious integration of façade surfaces with photovoltaic panels • storage and energy transfer favored by the diversity of the program. However, limiting the reasoning to a "positive energy" criterion can be reductive if the design does not fit into a more global logic, taking into account criteria such as carbon balance, gray energy or notions of use And maintenance and operation.
Nishi, a mixed office, commercial and residential building, combines light with nicks that sculpt the facades to bring natural light to the heart of the interior spaces. At the heart of the island, the courtyard seems to extend into the interior of the building. This work on the depth reinforces the visual transparency of the ground floor and brings the inner courtyard closer to the street. This space resumes the tradition of the Lyons places in "stabilized", planted with trees and shrubs. The terrain rises to form dunes protecting the wind and allow the planting of trees with tall stems. Wooden benches are inserted along the dunes and vegetated areas. At night, the lighting integrated into the façade highlights the faults. The inner courtyard is also illuminated in order to delineate the pedestrian walkways and illuminate the plants. On its two upper levels, Nishi accommodate 4 villas on the roof, jewels of HIKARI. Fruits of a particularly well-designed design, the villas aim at the maximum well-being of its inhabitants. Spaces bathed in light, exceptional view on the Darse of La Confluence, optimized acoustic and thermal comfort; These duplexes T3 and T4 / 5 of exception consist of a part day with vast salons and extended kitchens of terraces, and a part night on the floor, with the rooms and bathrooms, also extended of terraces . Some houses are designed with elegant interior patios.

The demonstration and monitoring phase, which will follow the delivery of the building, will cover and analyze all available parameters in order to adjust the technical factors of the island and its equipment to make it actor, as a living being, its behavior And its energy strategies, in the service of control and the economy of consumption.

BEMS (Building Energy Management System)
Jessica Boillot (JBoillot@toshiba-tsf.com)
The BEMS (Building Energy Management System) is the centralized management of the building's parameters, which allows to regulate the production of hot or cold, as necessary, in a synergetic way with the optimized use of point energy overproductions (Cogeneration, energy storage, energy recovery, etc.).
This BEMS, which favors the use of biomass (rapeseed oil) and therefore the economy of primary energy consumption, restores a statistical profile of the whole island over the year synthesizing production and consumption.
The demonstration and monitoring phase which will follow the delivery of the building will cover and analyze all available parameters in order to adjust the technical factors of the island and its equipment to make it actor of its behavior and its energy strategies, And this in the service of the control of energy and the economy of consumption.
The Hikari islet is at the crossroads between the first development phase of Lyon Confluence and the new district of the Marché Gare developed by the architects Herzog & de Meuron. Located at the corner of Charlemagne and Place Nautique, Hikari benefits from the very high quality environment of the Sainte-Foy-Lès-Lyon hill.
