// Descripción
BGL BNP Paribas starts in 2013 the construction of two new buildings (oKsigen and eKinox) in Kirchberg, with the aim of bringing
together most of the employees of the BNP Paribas Group in Luxembourg on one site.
This large-scale project consists of a 14-storey building and a second 6-storey building, both connected by a common basement
on two levels, for a total area of 52,000 m² and a capacity of 3,000 personal work places.
As project manager, BGL BNP Paribas Facility Management
Ensured during the entire works that the buildings were delivered on time and that they met the needs of the occupants. The
delivery of the building was thus possible in early 2016, and all occupants took possession of the premises in April 2016.
Concerned about its CSR policy, BGL BNP Paribas has launched the challenge of obtaining a triple environmental certification
with a European dimension for this project. Exceptional HQE certification has already been obtained in the realization phase,
BREEAM and DGNB are in the process of being obtained.
With its exceptional infrastructure, BGL BNP Paribas also puts the emphasis on the well-being of its occupants. There is a
nursery, a fitness center, sports locker rooms, a concierge, an XXL auditorium, a fun zone (billiard table, ping pong table, piano,
Wii console, arcade terminal ...) Panoramic view on the 14th floor with a breathtaking view of the city of Luxembourg, a 360 °
terrace on the 15th floor, and numerous dining areas (outside brasserie, lounge, contemporary café, cafeteria, canteen).

Filosofía ambiental del promotor :
In designing the project, the BNP Paribas Group in Luxembourg focused on respecting the
environment. Particular attention has been given to eco-friendly technologies and minimal consumption of energy and natural
resources. The Group has launched the challenge of obtaining a triple environmental certification with a European dimension for
this project. Exceptional HQE certification has already been obtained in the realization phase, BREEAM and DGNB are in the
process of being obtained.
Descripción de la arquitectura :
The BNP Paribas real estate complex in Luxembourg identifies itself as an urban object at the
entrance to the Kirchberg Plateau, thus becoming the East Gate of the City of Luxembourg. The site consists of 2 new buildings,
one of which is 6 storeys high, on J.-F. Kennedy Avenue, and a 14-storey building on Edward Steichen Street. The two buildings
are located on a two-storey basement connecting J.-F. Kennedy Avenue and E. Steichen Street with connections to the existing
3rd Kronos Building. This connecting platform integrates the common functions: reception, visitor lounges, training center, 499-
seat auditorium, fitness center, catering areas, etc. The car parks are spread over several basements under the base and are
accessible from E. Steichen Street. The courtyard, joining the two buildings, is landscaped in the extension of the gardens
designed by the landscape architect Jacques Wirtz for the Kronos building.

A feasibility study on the use of renewable energies was conducted. Concerning the supply of heat: -The obligatory connection
to the district heating network of the city of Luxembourg represents an economically and ecologically recommendable system. -
Thermal solar collectors for the production of domestic hot water lead to a reduction of CO2 emissions of about 5,000 kg / a for
an energy price increase of only 0.3 Cent / kWh.

Funciones Smart Building :
The GTB controls the opening or closing of the blinds according to the sunshine of the facades
which makes it possible to facilitate the solar thermal input in winter and to limit this same contribution during the summer
period.

Use of water

Categoría del producto: Management / Others
Descripción:
Water being a valuable resource, its rational use was one of the major environmental themes in
the design of the building. This concept has been developed along three main lines: 1. Minimize
city water consumption 2. Maximize harvesting and use of rainwater 3.Reduce wastewater
discharges as much as possible and To contain the flows discharged to the river in case of floods
The reduction of consumption in town water (potable) has resulted in the installation of taps for the
washbasins with pushbutton or photoelectric detector and flow rate limited to 6 liters / minute.
Each sanitary warehouse is equipped with solenoid valves on the separate circuits of drinking water and gray water, which
supply respectively the faucets of the washbasins and the flushes of water (cisterns and urinals) which automatically break as
soon as the detection of Presence detects that the room is empty, which automatically limits the overconsumption linked to leaks
and taps that could dysfunction. The rainwater of the 2 roofs of the building is recovered and stored in two tanks with a unit
capacity of 250 m³; This rainwater is used in spring and summer for irrigation and feeding of ornamental water basins and is used,
if available, as a sewer for the production of gray water (see below). The production of osmosed water has been favored to the
detriment of traditional salt water treatment. This osmosed water is used for the adiabatic humidification of air-handling plants,
instead of production by steam boilers (centralized or decentralized) which are highly energy-consuming and not very rational in
terms of water consumption. This osmosed water is also used for the production of natural ice water to obtain an adiabatic effect
in hybrid cooling towers, which reduces the consumption of electrical energy. This osmosis water is also used in the kitchen for
dishwashers. If the water was softened by saline (or chemical), there would have been regular releases of water concentrated in
salt (and other chemical stabilizers) into the sewers. In addition, the retentates (the highly mineralized fraction separated from the
osmosed water during the production of the latter) are recovered in their entirety in order to serve as gray water for flushing toilets
(bowl and urinals). Depending on the availability of rainwater, gray water may consist of a mixture of retentate water and
rainwater. The rainwater that is not recovered (the one harvested in the forecourt) is first directed in a gravity manner to catchment
basins calibrated opening in order to limit the flow of water discharged to the network of rainwater Which is directed towards the
river and therefore to limit its participation in the risks of flooding.
Comentarios:
To complete the overall consumption and production of water are supervised and counted through the tool GTB (Technical
Management of the Building). The numerous counters make it possible to analyze well the consumption which is used for good
behavior and, if necessary, the implementation of corrective actions.

Entorno urbano :
The BNP Paribas Banking Center in Luxembourg is strategically located at the entrance to the Luxembourg
City business district, symbolizing the city's main entrance. It is surrounded by, among other things, the city's convention center, a
hospital, a multiplex cinema, and a shopping center, providing numerous facilities for employees of the CBK site. The many
restaurants and bars nearby will also satisfy the greatest number. Mobility being at the heart of the concerns of the Kirchberg
Urbanization Fund (FUAK), the district is already well served by city buses, and also has several self-service "Vel'oh" stations .
The arrival of the Tram before the end of the year will however make it possible to reach the city center in less than 10 minutes,
and the future Railway Station of the Pfaffenthal will be 5 minutes away. Equipped with a number of parks, the area also offers a
lot of space for green spaces, enabling employees to indulge in all types of outdoor sports. The Sports Center "D'Coque" is also
equipped with an Olympic swimming pool and also hosts festive events such as concerts (Night of the Proms), varied sporting
events or solidarity (Relay for Life). From a cultural point of view, art enthusiasts will be able to visit the MUDAM (Museum of
Modern Art of the City) for permanent or temporary exhibitions, or at the Philarmonie to attend various more classical concerts. In
short, the district of Kirchberg is definitely a changing district where it is good to work.
