The Thémis is an office building of 10,655 m², located on Lot N4 ZAC Clichy-Batignolles (Paris 17th), in a lively neighborhood, changing and very well served. The original architectural design of the Themis, the structural innovations and the pioneering E + C label have contributed to making this pioneer building a landmark building in sustainable real estate.
Designed and produced under BIM by the architect Corinne Vezzoni & Associés, it develops a linear of 80 meters on the device which creates an optical dynamics thanks to the inclined glass walls as well as an emblematic south facade, offering a real green living tableau , with more than 260 climbing plants that dress the facade of the building. The predominance of wood, with the mixed wood-concrete structure and CLT floors, makes Themis a building of architectural excellence, serving sustainable development.
This commitment by ICADE for sustainable development, which is expressed through Thémis, was notably recognized by the award of the first E + C label awarded to a tertiary building. Themis has also achieved a high level of performance. rewarded by the E2C2 rating which highlights a very good energy performance and a level of excellence in terms of reducing the carbon footprint. Having participated in the pilot project of the label, the Thémis demonstrates that it is possible to reach high objectives of greenhouse gas reduction from construction, as well as in operation as it was evaluated during the projections. Themis is a pioneering building for low-carbon labeling, demonstrating the real estate sector's carbon-saving potential. To demonstrate its overall environmental quality, Thémis is also labeled HQE Excellent (2015 reference), BREEAM Excellent (2013 reference), Effinergie + (RT 2012), Biosourcé (2015 reference) and BBCA (Bas Carbone building).
Thémis' reasoned construction, linked to its mixed wood-concrete structure, and its controlled exploitation, thanks to geothermal energy production, allow it to be exemplary in environmental terms. The 235 m² of planted spaces, in close connection with the ground floor, and the 890 m² of green roof are also a key element of this achievement, The Thémis project is the real showcase of sustainable development of ICADE .

The location of the building and ICADE's commitment to sustainable development and innovation have led to strong and structuring architectural choices that make Thémis a unique building. As such, Themis is the first tertiary building to be awarded the E + C label, which rewards energy-efficient buildings and the reduction of their carbon footprint.
First, the location of the building played a key role in the design choice. Indeed, the parcel on which the building was erected is located near the High Court. It is a very tall building, 38 floors, which is in the form of several boxes resting on each other. So we had to deal with this imposing building. From then on, two choices were offered to the architect: to work in a certain continuity or to create a very differentiating building. The bias was to work in harmony with the existing. The Themis is therefore a particularly luminous, transparent and eye-catching building, while remaining in the continuity of its predecessor, but creating its own image.
Secondly, the location of the building required a unique architectural treatment that managed to unite in symbiosis architectural ambitions and environmental performances. Indeed, the building is located in the perimeter of the City of Paris and its construction was therefore subject to the Climate Plan of the capital. ICADE has chosen to capitalize on the context conducive to the fight against climate change as a lever to enhance its ambitions, both from the point of view of energy consumption and greenhouse gas emissions.
Then, the north facade of the plot along the ring has given rise to other strong choices. In addition to the appropriate treatment of noise and air quality factors, this northern facade required a distinctive idea from an outside point of view to animate the ring road, and from an interior point of view to the building. , enjoy an interesting light: the northern light.
In order to deal with these issues, a particularly imaginative idea arose from the spirit of the architect, Corinne Vezonni (from Corinne Vezzonni and Associates). Indeed, she was inspired by designers of perfume bottles. In particular, she asked them how the vials were designed to produce such shifting light reflections, the idea being to animate the visual of the peripheral side facade through changes in light. Thus was born the concept of double skin, with a straight outer skin, continuity of the court, and an inner skin inclined to produce these changes of light. The double skin on the north facade was also an opportunity to accentuate the insulation, to better protect the building from the noise of the device, as well as to allow a better entry of natural light through the use of glass.
Finally, the south facade overlooks a future bus parking. There are two challenges on this side. First, an integration of summer comfort to limit the need for cooling, and on the other, a need to present a facade attractive and pleasing to the eye. The chosen concept is a cladding of the facade with potted vegetation. The chosen plants will climb on supports designed to limit the entry of direct light, and therefore heat, into the building. This largely vegetated facade will also act as a purifier of the outside air while animating in a very pleasant way the future place.
With respect to the interior of the building, the bias was focused on the use of low-carbon materials, such as linoleum flooring, mixed wood-concrete structure and CLT floors. The choice of eco-materials results in a high-quality interior and the obtaining of low-carbon and E + C- building labels.
The architectural theme at the heart of Thémis is clear: the promise of unparalleled comfort for the end user, with a high level of environmental performance at the service of a low-carbon energy transition.
If you had to do it again?
The choice of BIM was quickly made, especially at the request of the architecture team. This choice made it possible to work in a collaborative way between the different actors of the design. BIM is a design tool that informs many parameters of a project, including building components. This is why the life cycle analysis part (LCA) could have been done under BIM. Indeed, one of the interests of the BIM is there: by informing the LCAs of the components in the BIM tool, it is possible in the short term to obtain the global LCA of the automatically generated building. However, despite the willingness of ICADE to go far in the use of LCA and BIM, this was not the case on this project. This is the next step to be achieved, and this will be the case in future ICADE projects, because as part of its participation in the Digital Transition Plan in the Building (PTNB), ICADE is working on new construction projects with the incorporation of LCA tools directly into BIM. This will go further in monitoring and achieving the environmental performance objectives of buildings.

Glued laminated wood
Opere strutturali / Struttura - Involucro - Finitura
The choice of structure was quickly focused on a mixed wood-concrete structure. The posts and lighters are made of laminated wood, PEFC certified. The wood chosen to play this role is a wood of French origin, it comes from the Vosges.
The main difficulty in using this product is the wood-concrete mix of the structure. Wood is a living material and concrete is a mineral material. Wood prefabrication always requires an on-site fit between the concrete structure and the wood structure.
The Thémis is located in the ZAC Clichy-Batignolles which will eventually have a large park of 10 hectares and more than 500,000 m2 of mixed programs. The revitalization of this sector of the 17th arrondissement is also part of the metropolitan dynamic at work in northwestern Greater Paris. Clichy-Batignolles is involved in the EcoQuartier certification process issued by the state. Moreover, since the ZAC is on the territory of the city of Paris, the constructions that are planned there must respect the ambitious Climate Plan of Paris. As a result, buildings with high energy and environmental performance are expected, and Themis fits in very well.
With regard to mobility and transport, Themis is pampered. Located on Lot N4 of the ZAC Clichy-Batignolles developed by Paris Batignolles Aménagement, Themis is in the immediate vicinity of the ring road and the Porte de Clichy. The accessibility of the site is remarkable thanks to the presence of a vélib 'station, several bus stops (54, 74, 138, 173, N15 and N51), line 13 of the metro and the RER C. In addition , the commissioning of the effective T3b tram in December 2017 created a stop located 450m from Themis. Finally, the creation of a new station on metro line 14, scheduled to open in 2019, will be located 250m from Themis.
In terms of carbon emissions during the operation phase, obtaining the E + C label is a testament to anticipatory work and high objectives formalized in the design phase. In particular, the location of the site allows users to take advantage of public transport and thus generates a reduction in the number of parking spaces. This encourages users to abandon the car and thus reduce their carbon emissions, which is taken into account in the E + C- label. The location of Themis, which is an important element of the E + C label, has been integrated since the design of the building.
