Site plan

Insertion The ZAC PAJOL office space, situated in the 18th arrondissement of Paris, belongs to a vast regeneration project for this previously industrial area, which aims to become an emblematic sustainable neighbourhood. The 5000 m2 building is the first office building constructed in inner Paris which responds to the BBC速 certificate requirements. The project guarantees to regulate the cost of its future energy consumption, to environmentally compensate for the carbon emissions produced during its construction, and to comply with the HQE速 label.

Typology Inspired by the style of the 1930’s "HOTEL INDUSTRIEL”, this new office space is located adjacent to “La HALLE des MESSAGERIES des DOUANES” and parallel to the railway lines leading to the “GARE de l’ EST”. The solid linear volume is simultaneously open to its surroundings: the park, the street, the warehouses. The four facades vary, depending on their orientation on the site, to offer an exceptional perspective towards the city.

Recognisable from the distance, the building marks the crossroads of rue PAJOL and rue RIQUET. When approching, figures become visible through the structure’s subtle transparency.

Facade The material continuity of the roof and facades accentuates the monolithic aspect of the building, and its apparent rigidity contrasts with its internal flexibility. The facade is constituted by 50% of glass and 50% of concrete.

The opaque surfaces are composed of a 16cm thick exterior insulation and a mineral composite material called ACRYTHERMŠ.

The building's structure in construction

Structure The concrete supporting structure follows a grid of 7.73m by 5.50m in plan, which repeats on each floor.

By reducing the primary structure of the building to a central core and load-bearing faรงade, an office space with maximum flexibility is created.

Transversal section

Plan Linked by a common central zone, the building extends on seven floors, with a rental area of 4854 m2 of office space to accommodate 500 people.

The central core provides the entire vertical circulation (2 elevators and 2 staircases) and the necessary service rooms such as kitchenettes, WCs, server and storage rooms. Four floors of the office space, with an area of 889 m2 each, can be subdivided using a base grid of 1.35m by 1.35m for individual offices with a minimal area of 2,70m x 2,70m, or remain

uninterrupted for open-plan offices.

Each floor can be divided into a maximum of 40 units. The ground floor provides a surface dedicated to commercial use, a cafeteria, secure bike storage, as well as an opening to the 217m² garden. The simple typology employed by the project, with its highly adaptable interior and timeless envelope, establishes a functional and durable building.

Sustainability The building’s approach to sustainability utilises several strategies. The prefabricated structure and facade combine high performance finishes and insulation. All facades contain openings to naturally ventilate the building and the south façade is triple glazed to prevent solar gain in summer. Low-energy gradable lighting, controlled by light detectors, operates throughout the building.

Visualisation of the planted roof

Pipes

The roof acts as the fifth façade of the building; 40 m2 of photovoltaic cells generate energy, planted areas store water to reduce surface run-off and the incline is equipped to prevent overheating and thermal losses.

These systems enabled the validation of the BBC ® Label, a BREEAM evaluation level « Very Good », as well as the HQE label. A quantitative assessment of emissions ® ADEME for the building’s conception and construction was realized in order to regulate their impact. A partnership reforestation project was completed for the “GARANTIE Carbone COMPENSÉ ®” of the emissions associated with the construction of the building, which emphasizes a global environmental approach throughout the project.

Materiality Concrete, metal and glass are the three dominant materials used in the project, following the idea of a typical “Hôtel Industriel”. Two different types of concrete were used: reinforced concrete for the structure and ACRYTHERM©, a highly performativity concrete composed of 80% quartz with an acrylic additive, for the facade.

Natural light enters the building through large windows. A solar shading system enables the user to vary light and heat, which generates irregularities on the systematic facade.

Dans le cadre d’un vaste projet de réha bilitation du 18eme arrondissement de Paris, le Pôle entreprise de la ZAC Pajol marque le renouveau de cet ancien site industriel en reconversion. Au coeur de ce projet, dont l’ambition est de faire du site un éco-quartier emblématique, ce bâtiment de plus de 5000 m2 est le premier immeuble de bureaux réalisé dans Paris intramuros disposant d’une certification BBC® qui garantit un niveau de charges maitrisé, une compensation carbone des impactes du chantier, et le label HQE® Typology Inspired by the style of the 1930’s "HOTEL INDUSTRIEL”, this new office space is located adjacent to “La HALLE des MESSAGERIES des DOUANES” and parallel to the railway lines leading to the “GARE de l’ EST”. The solid linear volume is simultaneously open to its surroundings: the park, the street, the warehouses.

The four facades vary, depending on their orientation on the site, to offer an exceptional perspective towards the city. Recognisable from the distance, the building marks the crossroads of rue PA JOL and rue RIQUET. When approching, figures become visible through the structure’s subtle transparency.

Le bâtiment, dont la structure s’inspire de la tradition des Hôtels industriels, s’insère dans le prolongement de la halle des messageries des douanes, parallèlement aux voies ferrées menant à la gare de l’Est. La simplicité de son architecture monolithique, largement ouverte vers l’exterieur, dialogue avec les autres éléments présents sur ce territoire fractionné, qui offre une perspective exeptionelle sur la ville. Ses quatre façades varient subtilement en fonction de leur orientation, vers le parc, la rue, les entrepôts... A distance, un bloc à toiture oblique marque le carrefour des rues Ricquet et Pajol. En s’approchant, sa transparence fait apparaître des silhouettes diffuses dans la profondeur du bâtiment.

Facade The material continuity of the roof and facades accentuates the monolithic aspect of the building, and its apparent rigidity contrasts with its internal flexibility.

The facade is constituted by 50% of glass and 50% of concrete. The opaque surfaces are composed of a 16cm thick exterior insulation and a mineral composite material called ACRY THERM©.

Le bâtiment est enveloppé d’un voile de béton, et ses fenêtres situées sur le meme plan que la façade minérale, esquissent un volume simple dont la rigidité apparente contraste avec une souplesse d’utilisation. la façade verticale est constituée à 50% de vitres soit de 50% de surfaces opaques. La partie opaque, est composée d’un isolant d’une épaisseur de 14cm disposé en partie extérieure de la façade, ainsi que d’une enveloppe en béton acrytherm.

Structure The concrete supporting structure follows a grid of 7.73m by 5.50m in plan, which repeats on each floor.

By reducing the primary structure of the building to a central core and load-bearing façade, an office space with maximum flexibility is created.

La structure porteuse en béton blanc, d’une trame de 7m73 dans le sens de la longueur du bâtiment et de 5m50 dans le sens de la largeur répond aux différents besoins du bâtiment à tous les étages tout en restant la même sur toute sa hauteur. La séparation de la structure et du noyau technique central, définit, y compris dans les futurs espaces paysagés, une zone de circulation entre le noyau technique et les poteaux centraux. La partie structurelle en façade extérieure, simplifie la volumétrie intérieure des espaces de travail, en en facilitant l’aménagement et la partition.

La surface totale du bâtiment, 5000 m2 pour 500 personnes, fut conçue afin de proposer une multiplicité de subdivisions des surfaces dans les étages, le bâtiment se déploie sur sept niveaux reliés par un espace central commun. Ce noyau central rassemble escaliers, ascenseurs ainsi que les espaces auxiliaires requis a chaque étage. cuisine, WC, espaces de stockage. La flexibilité d’aménagement des plateaux permet une large variété de scénarios d’occupation. Ainsi, les quatre étages de bureaux, de 900 m2 chacun, peuvent accueillir aussi bien de petites unités que de grands espaces paysagés. Chaque étage peut ainsi etre divise en un maximum de 40 unites. Le rez-de-chaussée offre une surface commerciale se développant en double hauteur avec mezzanine, ainsi que des locaux ouverts sur le futur jardin. Quant au dernier étage, il est conçu à la manière d’un atelier et se déploie sous une nef de béton et de verre. La simplicité du langage architectural et sa flexibilité en font un bâtiment volontairement durable.

Sustainability The building’s approach to sustainability utilises several strategies. The prefabricated structure and facade combine high performance finishes and insulation. All facades contain openings to naturally ventilate the building and the south façade is triple glazed to prevent solar gain in summer. Low-energy gradable lighting, controlled by light detectors, operates throughout the building Outre sa durabilité, la qualité environnementale du projet réside par ailleurs dans de nombreux critères. La structure et la façade en éléments préfabriqués permettent de combiner une haute performance en termes de finition et d’isolation avec la réduction de travaux lourds pendant la phase de chantier. L´ isolation est par ailleurs accentuée par la plantation de la majeure partie de la toiture, également équipée de 40m2 de vitrages photovoltaiques .

Materiality Concrete, metal and glass are the three dominant materials used in the project, following the idea of a typical “Hôtel Industriel”.

A l’image de l’hôtel industriel, trois matériaux sont particulièrement présents: béton, métal et verre. La structure porteuse ainsi que la façade sont faites de béton haute densité qui ne se ravale pas. Appelé acrytherm, il est composé à 80% de quartz, et d’un additif acrylique.

Les larges baies vitrées permettent un éclairage naturel optimal des locaux, dont la combinaison avec le dispositif d’occultation inséré dans le vitrage à fleure de façade, permet une modulation infinie des apports lumineux et calorifiques. L’ensemble des fenêtres des bureaux sont ouvrables, indépendamment les unes des autres.
