Full concept/idea title
Restoring the sense of belonging by the renovation of a cultural heritage architecture

This project refurbishes the remaining structural skeleton of the Parisian Musée des Arts et Traditions Populaires (1972), to transform it into a multifunctional cultural center. The new architecture connects with the historical heritage of the previous museum and of the surrounding park, while synergically interacting with contemporary transformations of the place. The building becomes a symbolic "lighthouse", to shape a new landscape and strengthen the sense of belonging for the neighborhood.

Please provide a summary of your concept/ idea

After years of abandonment, a structural skeleton is all that remains of the Parisian Musée des Arts et Traditions Populaires – ATP (1972), one of the masterpieces of J. Dubuisson. Located at the edges of the park “Jardin d’Acclimation” (1860), this relic stands almost unnoticed next to the Louis Vuitton Foundation (2014), a glass architecture by F. Gehry, whose scenic morphology is inspired by the sails of ships.

My refurbishment project reconverts the building into a polyvalent cultural centre with a high-performance envelope, interacting with the surrounding environment. Architectural, technological, esthetical and structural choices are connected in a systemic way with the historical and natural values of the place, to enhance the memory of this heritage building and its interaction with the neighbourhood, while preserving the existing steel framework and respecting Paris Energy Plan for 2050.

This proposition starts from archive research and is supported by engineering and regulatory insights, such as the study of building elements and the comparison between the historical loads and those expected from the renovation, to draw up a structural, technological and functional adaptation, with particular attention to the fruition for disabled people and to the improvement of human comfort and bioclimatic behaviour.

The creative use of innovative technologies, able to adapt to meteorological changings, such as electrochromatic facades, characterize the building from an architectural, energetic and communicative point of view. The building’s refurbishment aims to conclude unfinished narratives, becoming a metaphorical lighthouse towards which Ghery’s glass vessel is docked, recalling the landscape of Fort St. Jean’s lighthouse in Marseille, alongside which the original collection of Musée des ATP has been transferred. Therefore, the intervention regenerates the spirit of the place, fostering local identity and sense of belonging for the whole area.

This refurbishment embraces the original vision of the nearby Jardin d'Acclimatation, aimed to adapt plants and animals to the Parisian climate, through the conception of a bioclimatic dynamic building, blended with its natural surrounding and able to respond to environmental changes.

Sustainable architectural strategies, considering energetic and human comfort issues, includes the use of natural resources, the mitigation of extreme meteorological occurrences and the improvement of energy efficiency by minimizing lighting, heating, and cooling loads, thanks to façades solutions adapted to their orientation. In the tower's longitudinal façades, turned to east and west, internal shading allows the entry of thermal energy in winter. During summer, electrochromatic glazing darkens the glasses to avoid glare, mitigate interior light and minimise cooling consumptions. To ensure sun shielding, the opening of windows adopts parallel hinges. The south façade, exposed to high solar radiation, has a double skin with internal motorised slats. In summer, natural upward ventilation is allowed, while in winter the slats close to store heat. On the north façade, exposed to cold winds, triple glazing reduces heat loss. To illuminate the exhibition spaces with natural light, skylights from Dubuisson's original project, changed in their morphology, have been introduced in the roof of the platform. For those far from the tower, not affected by shading, the opaque slope is turned to south and covered with photovoltaic panels.

The conservation of the existing structure enhances circularity and re-using. Furthermore, to accomplish bioclimatic regulation, the project employs geothermal energy through radiant floors, rainwater collection and a solar thermal system to heat sanitary water, while high-albedo materials, vegetation and water mirrors reduce urban heat island and safeguard population from heatwaves. These solutions make the project exemplary in sustainability.

Please give information about the key objectives of your concept/idea in terms of aesthetics and quality of experience beyond functionality and how these would be met.
Please highlight how the concept/idea can be exemplary in this context

The project enhances the aesthetic value of sustainable technologies through the composition of an architectural narrative that aims to reconcile the geometric rationality of the remaining structure of the Musée des ATP with the morphological complexity of the Fondation Louis Vuitton, which represents a glass vessel landed in the park of the Jardin d'Acclimatation.

Drawing inspiration from iconographical research on naval scenes, exemplified by Hogenberg's 1572 etching of the port of Genoa, I decided to complete the metaphor by reinterpreting the Musée des ATP as the harbour pier with the lighthouse tower towards which the Gehry's “glass vessel” is heading. In this sense, the archetypal function of the lighthouse, namely light signalling, is reinterpreted in a contemporary key, thanks to electrochromatic glasses. This technology, which minimises cooling consumption, transmutes the facades in an artistic orientation point in the evening, using the building's lighting to compose dynamic luminous graphics, signalling the museum's position and its creative vocation.

Other technological elements that responds to functionality and sustainability assume aesthetic relevance: the walls of the exhibition platform recall, in a translucent way, the vertical texture of the original opaque envelope through channel glass, allowing diffuse natural lighting for interior spaces; the garden roof, on the exhibition platform, improves the landscape view from the top of the tower, reconciling its image with the surrounding garden; the water basin, which is part of the solutions to reduce summer overheating, becomes an element of conceptual connection with the Fondation Louis Vuitton and its aquatic area, contributing to the metaphoric lecture of the vessel and the lighthouse; finally, the original steel structure, entirely preserved and characterised by diagonal bracings, remains visible from the glass facades of the tower, like a design artefact in a display case.

Please give information about the key objectives of your concept/idea in terms of inclusion (equal opportunities, public participation, citizen engagement, co-design, universal design, accessibility, affordability, etc.) and how these would be met.
Please highlight how the concept/idea can be exemplary in this context

The project is inclusive at different levels. It’s inclusive towards the population since it’s a multifunctional building with a cultural vocation. In fact, it offers a diversified pool of activities at all hours of the day, with a museum, a theatre, a library, a reading space, artisans' housing and studios that can be visited, exhibition spaces for the artistic productions, a restaurant and a belvedere on the park and the city.

An articulated system of ramps, that connects the street level to the raised entrance and to underground exits, solves the problems of accessibility, allowing the building to be inclusive of all categories of users. In addition, the museum is directly connected through its main transversal path to the Jardin d'Acclimatation, allowing visitors to enjoy the beauty of the garden and to take open-air walks, alongside those in the building. Encouraging people to walk in a natural landscape, easily accessible by the city through public transportation, in alternative to drive elsewhere by car, accounts for improving healthy physical activity and for pollution reduction.

The concept of inclusion has also been applied to the relationship between the architecture and its context. The architectural interpretation of the building as a lighthouse picks up on the metaphorical vision of the Fondation Louis Vuitton, creating a single scenario that integrates and highlights both architectures. Finally, the project is historically inclusive, as it uses innovative technologies in a respectful manner of Jean Dubuisson's original design: for instance, the construction of skylights on the roof of the exhibition platform recalls those in the architect’s drawings, the electrochromatic glasses respect and enhance the modularity of the original façades, the preserved structural bracings are shown behind the glass façades of the tower, and the vertical texture of the platform's opaque envelope is reinterpreted in a translucent way through the use of channel glass.

Please explain how these three dimensions would be combined in your concept/idea.
Please highlight how this approach can be exemplary

Design choices combine sustainability, beauty and inclusion in a systemic way, by responding to different needs, from the urban scale to technical solutions.

At the urban scale, the reinterpretation of the building as a symbolic "lighthouse" creates a signal for the community, while reconciling in a single narrative the recent transformations of the area (marked by the construction of the Foundation Louis Vuitton, which represents a glass vessel) and the history of the original museum (whose collection was transferred near Fort St. Jean’s lighthouse in Marseilles). This metaphorical representation is realised through the water basin, which echoes the one around the Foundation Louis Vuitton, reducing the urban heat island, and the electrochromic glasses, which optimizes the building's energy consumption during summer days, while becoming a source of light communication in the evening. The façade’s modular lightening becomes an element of attraction for the neighbourhood, arousing emotion and surprise while enhancing the regularity of the preserved historical structure. The creation of a multifunctional centre puts community at the core of contemporary use.

Among technical solutions representative of this synergy, the rooftop of the exhibition platform implements a set of skylights, recalling the ones envisaged in the original project, to optimise the natural illumination of the exhibition spaces below. In addition, the whole surface becomes a wide garden-roof, which improves the bioclimatic performance of the building, while integrating his aesthetic with the landscape of the park. In the parts not affected by the tower's shading, photovoltaic panels increase the sustainability of the building through renewable energy. 

A complex system of ramps guarantees the building's accessibility, making it affordable to all categories of users. A pedestrian passage through the building directly connects with the park, encouraging outdoor walks and contact with nature.

Please highlight the innovative character of the concept/idea as compared to mainstream practices in the field of the concept/idea.

The innovative character of the project is the result of a comprehensive approach, where the functional and technological adaptation of an existing structure responds, at the same time, to the needs of sustainability, aesthetics, inclusion and historical recall. One of the most innovative elements are the electrochromatic glasses, not only because they constitute a cutting-edge technology, but also for the creative use proposed in the project. In fact, despite these special glasses are designed exclusively for energy efficiency and light regulation during summer days, the project proposes to adapt their performances for artistic and communication purposes, allowing the composition of luminous graphics that enhance the modularity of the historical façade.

More generally, the technological and architectural solutions implemented in the different parts of the building (structural conservation, double skin, channel glass, skylights, green roof, water basin, ramps and paths, differentiation of façade technologies according to sun exposure, geothermal energy, natural ventilation, solar thermal system and photovoltaic panels) brings together functionality, environmental sustainability, historical references, aesthetics and inclusion.

Some of the above-mentioned technological adaptations also participate to enhance the security of the visitors and of the artistic patrimony of the museum as well. For instance, the skylights of the exposition platform have sensors to automatically close when rain impacts on the glasses and open when smoke is detected in the spaces below, while the slats in the double skin of the tower are in fire-resistant materials and closes automatically to prevent fire propagation in the air cavity.

The building's metabolism is synchronized with that of the park, reacting to the changing of seasons and to the times of the day, generating a dynamic architecture which evolves continuously thanks to its smart technological apparatus.

Please detail the general plans that you have for the further development, promotion and/or implementation of your concept/idea.

This project adapts an architectural heritage to today's climatic, territorial, cultural and functional context by a multidisciplinary approach.  Conceiving a building capable to benefit from the local environment and to respond to extreme climatic occurrences is also a key issue for new constructions. The urban environment acts on the buildings with wind, solar radiation, noise and pollutants. On the other hand, architectures intervene on the outdoor spaces by producing shade, altering natural ventilation, accumulating and releasing energy, varying the vegetation areas and intercepting/rejecting noise and pollutants. As the objective of the project was to refurbish an existing structure, the available actions were constrained in morphology and positioning.

To decipher the possibilities of urban design to alter microclimatic parameters (such as windspeed, air temperature, surface temperature, relative humidity and mean radiant temperature) and to find the right approaches to conceive more sustainable neighbourhoods (counteracting urban heat island and enhancing human thermal comfort), I am undertaking a PhD in Paris. The aim of my studies is to develop a systemic methodology for optimisation of built and vegetal forms through generative design, to reduce energy consumptions and outdoor thermal discomfort, improving the resilience of public spaces against summer overheating. The concept of architectural metabolism, where the building reacts to adapt to climatic variations, will be transposed from this project to new constructions, to establish, in the early stages of the design process, the morphological conditions to improve sustainability and thermal satisfaction.

The objective is to create a unique methodology, that can be adapted and replicated to all places, for the creation of “unique” architectural solutions, that rises from the microclimatic and environmental specificities of the area of intervention and that cannot be transplanted elsewhere.

Imagine that your idea/concept is awarded in the New European Bauhaus Prizes 2022. What kind of initiatives would you take throughout the following year (June 2022- June 2023)

The awarding by New European Bauhaus would promote the safeguard of historical heritage in danger, here exemplified by the Musée des ATP. After its abandonment, when demolition was evoked, a petition was held by the community to prevent the loss of this testimony of French rationalist architecture. As result, a renovation project, expected to be completed in 2020, was announced, followed by the dismantling of original facades and roofs in 2018. However, no advancement was publicly reported by now, while the exposition of the steel structure to weather conditions aggravates its state of degradation.

The Prize will bring attention to the preservation of urban heritage in a way that enhance attractiveness, circularity, climatic adaptation and sustainability. The challenge is to respond to these issues through solutions synergically cooperating in a single project. My proposal develops a multifunctional cultural centre to restore a positive sense of the place, breaking physical and social barriers. Innovative technologies make the architecture environmentally performant and aesthetically attractive, improving the inhabitant’s and visitor’s experience.

The Prize and Communication package would be used to implement visibility and data-sharing on these subjects: a video, illustrating the project, its methodology and its technological innovations, and a website, to freely download project details, photos and historic material from archive research, would be expected before June 2023. To raise awareness on similar situations to be safeguarded, the website could also welcome contributions on other architectural propositions on cultural heritage in danger.

The financial support would also aid my PhD studies on the issue of improving outdoor thermal comfort through urban planning, allowing me to attend to conferences/training schools. Production of scientific articles is expected in the next year, to share main findings with the community.
