ZAC Paul Bourget: innovative solutions for energy performance

The project : Located in the south of the 13th arrondissement, in the immediate vicinity of the municipality of Kremlin-Bicêtre, the Cité Paul Bourget was built in 1954 and 55 as part of an emergency housing plan for families. As dilapidated buildings cannot meet accessibility standards for people with reduced mobility, nor environmental standards, it was decided to redevelop, after consultation with residents, the sector as a whole. The project aims to build a mixed neighborhood bringing together social and intermediate housing, offices, convenience stores and activities as well as cultural facilities. The objective: to make this space a district integrated into the city, attractive and dynamic.

A partnership to meet energy challenges : With a majority of social housing, the buildings in the district have been designed so that they consume less energy to reduce the costs of charges for residents but also to achieve the objectives of reducing gas emissions greenhouse effect displayed in the City of Paris Climate Plan.
It is within this framework that the Partnership Agreement signed in 2016 between the City of Paris, GRDF and SEMAPA is part of and that the ZAC Paul Bourget was chosen as an experimentation area. This experiment aims to assess the use of different high-performance and reproducible energy solutions for high-performance buildings, based on ambitious labels, benchmarks or certification (Effinergie +, E + C- benchmark, NF Habitat HQE certification).

Since 2019, two different energy solutions have already been put into service in order to compare them to a more traditional third. The objective being in 2024 to obtain eight solutions installed in different lots of the ZAC to carry out points of comparison.

This case study sheds light on the need to think about energy solutions no longer at the simple level of the built lot, but at that of the district reflecting the will of the actors to participate in the making of the sustainable city.

The data in this study are self-reporting, some are regulatory or related to external certifications.

Type of territory

  • A landlocked neighborhood

Covering an area of 4 hectares, the ZAC Paul Bourget is bounded to the north by rue Paul Bourget, to the east by avenue de la Porte d'Italie, to the south by the ring road and to the west by the Kellermann park.

At the heart of a dense network of communication axes, the ZAC Paul Bourget has optimal accessibility (road and public transport: metro 7, tram 3a, Bus 47) as well as visibility from the ring road. These elements suggest that its strategic location at the gateway to Paris could be a guarantee of potential attractiveness as well as a very favorable economic and commercial context.

However, the district's internal services (rue Paul Bourget and square Rosny Ainé) are dead ends and the district is landlocked to the south and west between the ring road and Kellermann park.

Quality of life / density

  • Support residents during the implementation of the project

According to a survey conducted by SGIM in 2008, 53 households in Cité Paul Bourget have lived in the same accommodation since the site was built in the 1950s and 1/3 of households have lived there for more than 30 years. Priority was given to the construction of new buildings making it possible to reconstitute the 365 social housing units managed by Elogie-SIEMP before the destruction of the old buildings at the end of the works.

Prior consultation was carried out with residents by the City of Paris in 2011 and 2012 through exhibitions, public meetings and thematic workshops.

Social diversity 

  • A residential area

The ZAC Paul Bourget aims to make multicultural, multigenerational and multifunctional encounters possible. The creation of social housing and student housing bring social diversity to the project, and a media library, the beating heart of the district, constitutes a meeting place for multiple audiences, by strengthening the social link between the users of the district and the inhabitants.

Although the district still retains for the most part its residential character, the project aims to include in the development program activity buildings, offices, local shops and equipment satisfying both users of the district and its residents. .

  • Promote new forms of living

Delivered in mid-2021, the Alto Plano (lot 3), an innovative hotel residence, will respond to new ways of living in the city. It will have a variety of uses (ground floor open to all offering all types of services: sport, showroom, co-working, library, catering) for a variety of budgets (day service, medium and long stays) : students, tourists or mobile workers will be able to cross paths there.

Ambient air quality and health

  • Proximity to the ring road

The development of the ZAC is focused on respecting biodiversity and the health of residents and users of the neighborhood. While the air quality is relatively good in the 13th arrondissement in comparison with the central arrondissements of the capital, studies upstream of the project (2010 and 2012) nevertheless revealed that the rate of nitrogen dioxide (NO2) was above the applicable threshold.

This situation is explained by the location of the district between two major axes which intensify the air pollution but also noise: the avenue de la Porte d'Italie and the ring road. In terms of noise pollution, the ring road is classified as 1, avenue de la Porte d'Italie in category 2 and boulevard Kellermann in category 3.

  • Respond to air pollution and noise pollution

During the construction of the district in the 1950s, this problem did not exist since the section of the ring road adjacent to the Cité Paul Bourget was created in 1960 and the work on the ring road ended in 1973. Thus, the housing were not historically protected from these nuisances by a barrier structure. It was therefore essential to create acoustic protection for the heart of the district, while providing visual breakthroughs.

The constructions do not have the appearance of a "noise barrier" but must have the functionality: the division of the built elements into different volumes and the presence of vegetal continuities also make it possible to find visual breakthroughs and openings towards the sky giving a certain visibility to the district on the environment in which it fits.

The plant continuity helps to isolate the district from the nuisances of the ring road with plantations all along the latter. Also, all the roofs, facades and terraces of buildings of public interest (shops, hotel residences and library) have been vegetated in order to reduce heat islands.

Local development

  • Opening up objective

For a better integration of the district within the space in which it fits, the ZAC aims to invent a new image on the edge of the ring road and in the immediate vicinity of the Kellermann park. The buildings, visible from the ring road and Porte d'Italie, constitute the main facade of the district towards this major metropolitan area.

Urban continuity must be created beyond the ring road with Paris but also with the municipality of Kremlin Bicêtre. Internally, rue Paul Bourget, initially a dead end that ended in a turnaround ramp, will have an extension with the creation of two new lanes from the turnaround loop. Also, a mobility strategy has been developed to ensure better integration at the city level at Cité Paul Bourget.

With the delivery of the first part of the public garden, the ZAC already benefits from an opening onto its environment with the creation of continuity between the district and Kellermann Park. The central part of the project consists of creating a link through the district's public garden between Kellermann Park and Avenue de la Porte d'Italie. We will have to wait for the final delivery of the garden to take advantage of the connection between the park and Avenue de la Porte d'Italie.

Functional diversity

Initially presented as a residential area lacking entertainment, equipment, services and shops despite its attractive location, the ZAC project aimed to participate in the social and economic development of the territory.

The urban project aims to bring programmatic diversity back to this district strongly marked by social housing. Within an almost monofunctional sector, a tertiary, commercial or equipment program brings new users back to the heart of the district. Bringing together places of life (habitat), work (employment) and consumption (commerce) within the same district thus ensure the functional diversity of the space.

The urban project program therefore breaks down as follows:

  • Housing program: a set of 9 buildings developed around the central green space.
  • Economic block: a set of offices, a hotel, commercial areas and a 17,800m2 basement for parking use.
  • Peripheral island: a hotel residence and a building dedicated to offices.
  • Facilities: establishment of a media library in the heart of the district responding to the challenges of both functional and social diversity.

Circular economy

Le Cercle (lot 11), which will be delivered at the end of 2022, aims to be a key location for the circular economy in the Arc de l'Innovation and on a metropolitan scale, focused on experimentation offering flexible spaces. The Circle is above all a pilot project that focuses on how to take into account the challenges of the circular economy, by associating in the same building an open and active ground floor, third places offering a great diversity of 'uses, and major account offices.

To invent the offices of tomorrow, the Cercle is experimenting with new ways of working and focusing on 5 themes: circular economy and reuse, nature in the city and urban agriculture, culture and leisure, sustainable food and circuits short, economic development and experimentation, by associating workspaces, open spaces, places of exchange, sharing and living, which can bring together building users, residents and stakeholders of the district, associations, residents ...

Mobility strategy

  • Strengthen the site's service and ensure its accessibility from major central points

The site is already connected to the major metropolitan economic centers thanks to the public transport network: Porte d'Italie, metro station line 7 and T3 as well as several bus lines located within 300 meters of the ZAC. The ZAC also has easy access to employment centers in the south of Paris (Rungis), easily accessible by the Ile-de-France motorway network.

Changes to the public transport offer are planned to facilitate service to the site: the opening of the T9 tramway scheduled for the end of 2020 connecting Orly to Porte de Choisy, as well as the extension of line 14 to Orly. Scheduled for 2023, this line extension includes the creation of a new "Maison Blanche" metro station less than 500 meters from the ZAC Paul Bourget

  • Favor gentle circulation

In consultation with the inhabitants, the district has been designed so as to ensure a journey time on foot or by bike between the places of mobility and the living space of less than 10 minutes.

Water management

  • Rainy waters

The topography of the district is that of a gently sloping land from east to west with a drop of 7 to 8 meters. The lowest point in the district is at the intersection between Kellerman Park and the ring road. The topography is therefore favorable to the natural flow of rainwater towards the Bièvre valley.

On the sidewalks, vegetated valleys will collect rainwater. The pavements will be concrete paving, with joints specifically designed to facilitate the infiltration of rainwater according to the commitments of the Paris Pluie Plan.

Biodiversity and natural areas

  • A Protected Green Space at the heart of the green belt

Located to the east of the historic valley of the Bièvre, the district has developed on the former bed of the tributary now covered by the Kellermann park, marking the point of separation between the two arms of the Seine. As Kellermann Park is a classified wooded area, the district is located in the heart of the green belt and plays an important role as a city-wide green corridor.

Composed largely by a Protected Green Space (EVP), the development of the district is therefore essentially based on the need to enhance the green space in the heart of the district and reconnect it to the natural environment that surrounds it. The project is part of an exemplary sustainable approach: a strong environmental ambition, expressed in the PLU , the Climate Plan of the City of Paris as well as the ParisPluie Plan.

  • Avoid the divide between built space and nature

The combination of the different plant layers in the living spaces seems essential for the respect of biodiversity and the Climate (2012 and 2018) and Biodiversity (2011) Plans of the City of Paris. In a desire for an adaptation strategy of the City of Paris in the face of the double challenge of climate change and the scarcity of resources, the district was developed according to the needs to strengthen the green network but also the opportunities of space.

The greening of the district allows the reduction of the heat island effect: the green spaces of the ZAC have been enhanced, in particular the 5 hectare Kellerman Park which has been enhanced with the creation of an 8000m2 garden in extension. This new public garden is also intended to bring a great variety of species to the site. In addition to the existing lime trees, 27 Japanese sophoras - these trees traditionally located near Japanese pagodas - 37 “Fastigiata” pedunculate oaks whose tops seem to rise skyward or 23 larches will be planted. As for the shrubs, you will have to reckon with the beautiful yellow flowers of the 197 male dogwoods or 112 broom plants. Sloe, hawthorn and black elderberry will, for their part, dot the decor with hints of red, purple and white.

The built lots have been designed with the objective of avoiding the divide between the built space and nature: biobased materials, terraces, roofs and green facades have been favored. Green roofs allow the reconstitution of a living environment left to the colonization of spontaneous vegetation and participate in the development of the site's biodiversity. To do this, it has also been planned to set up insect hotels and birdhouses, while ensuring that the use of pesticides is prohibited for site maintenance.

Reasons for participating in the competition(s)

​La ZAC Paul Bourget permet de mettre en lumière la nécessité de penser les solutions non plus à la simple échelle du bâtiment mais à celle du quartier reflétant la volonté des acteurs de participer à la fabrique de la ville durable.  Dans cet esprit, l’aménagement de la ZAC Paul Bourget repose sur cinq principes : 
  • Ouvrir le quartier sur son environnement urbain en améliorant l’offre de mobilité et en renforçant la continuité urbaine au-delà du périphérique, vers la commune du Kremlin-Bicêtre.
  • Offrir aux habitants un cadre de vie plus agréable par l’aménagement des espaces publics en faveur des circulations douces. 
  • Eviter la fracture entre l’espace bâti et la nature en reliant les espaces verts entre eux afin d’améliorer leur continuité, notamment par l’accessibilité et la lisibilité du parc Kellermann depuis l’avenue de la Porte d’Italie.
  • Proposer une offre de logements répondant aux exigences environnementales avec la mise en place d’une expérimentation couplant des solutions au gaz naturel avec des énergies renouvelables telles que le solaire, l'aérothermie ou la géothermie.
  • Favoriser la mixité sociale et fonctionnelle du quartier : (1) par la promotion de nouvelles formes d’habiter et la programmation d’une médiathèque, lieu de rencontres de publics multiples visant à renforcer le lien social ; (2) en regroupant au sein d'un même quartier des lieux de vie (habitat), de travail (emploi) et de consommation (commerce).
