The building of 37 Myrha Street in the 18th arrondissement of Paris comprises 4 social housing units (3 T3 and 1 duplex) as well as an activity space. The project, which meets the standards of the Climate Plan of Paris and the Habitat & Environment certification, is the result of a thoughtful environmental approach, notably through the use of an innovative material: hemp concrete. The establishment of two opposite facades, one on street, sober and legible and the other on garden, open and warm, enriches the project by contrast. The search for a constant pattern also gives a profound meaning to these facades which establish a strong dialogue beyond their apparent opposition. The ground floor includes a shelter for bicycles and strollers as well as a commercial space entirely autonomous and adaptable to various functions in order to be perennial and scalable. From R + 1 to R + 3, the houses are T3 of 73m ² largely open on the garden. The rooms to be live deployed on the South side, on garden, while on the North, on street, are positioned the rooms and the bathroom. On the R + 4 and the R + 5, a duplex of type T4 / 5 with a surface of 102m ² develops which enjoys, on its two levels, a small outdoor space overlooking the garden. In the R + 5, a common terrace accessible to all the inhabitants and bordered by a green roof is set up. The garden imposes itself in the project as a unifying space. Of the apartments, it is the place towards which all the glances converge. It articulates spaces by creating visual links and common uses. Hemp concrete, the main element of the physical and thermal envelope, is a non-structural material combining the qualities of hemp and lime. It brings the following environmental qualities: thermal comfort (inertia and hygrothermal regulation), reduction of losses (treatment of thermal bridges and reinforced insulation), reduced environmental impact of the material (renewable resources, positive carbon footprint, clean site) Lightweight structure (wood frame) and a wall with a high deformation capacity.
Sustainable development approach of the project ownerAs part of the redevelopment of the Château Rouge district entrusted to SEMAVIP by a public development agreement, the City of Paris entrusted the RIVP with the contracting authority for the construction of the building at 37 Myrha Street. The RIVP is committed to this project by requesting that it comply with Habitat & Environment certification. The RIVP enabled the realization of this ambitious project in terms of sustainable development by supporting the use of hemp concrete, an innovative material both in terms of construction and energy performance. Thus, the building at 37 Myrha Street reaches the "A Performance Profile" and is a "Low Consumption Building". It combines an approach of respect for the environment and quality of its architectural dispositions. Indeed, the label H & E allows a reflection on the comfort of the inhabitant, in particular in the logic of use of apartments and in the organization and layout of common spaces.
Architectural descriptionThe difficult terrain and the desire to reinterpret the architecture faubourienne have led the project manager to choose a light construction principle associating metal structures and hemp concrete. Respect for the site and architectural sobriety, the response to technical constraints and the pursuit of sustainable development objectives have been the priorities of the project management. For a good integration of the project in its environment, obedience of the lines of composition to a strong horizontal logic has been opted. It is a question of balancing the verticality of the volume by the use of several devices: the ground floor forming a substructure, the formal partition of levels, the partition of materiality on the façade, and the cornice to avoid water run-off. Thus, the façades revert to the faubourgian codes. On the street side, the project displays a smooth façade creating a continuity and a reading of the ordinary city of Faubourg. On the garden side, it is the look towards the nature which is privileged, with a planted garden and a warm diversity of the facades. This one is perceptible from the street and the building creates a set of transparencies from the public space. The building on 37 Myrha Street is an interpretation of the furbish building, taking into account today's realities of use and sustainability.

Contrary to what its name suggests, hemp concrete has nothing to do with traditional concrete. Non-structural, it is an insulating and ecological filling material. Its installation on supporting framework (generally in wood) is apparent to the historical constructive principles of dense urban environments: constructions with pan of wood and pan of iron. Conjugating the qualities of hemp and lime, it is projected horizontally on a temporary or permanent formwork bottom. It ensures a distributed insulation of the construction, significantly reducing thermal bridges. The hygroscopic nature of hemp gives the walls a healthy and natural breathing, avoiding the effect "tight box". Its inert character improves the comfort of summer and winter. Finally, hemp concrete is not limiting and allows to realize all types of facade (wood cladding, zinc, plaster ...) The use of hemp concrete allows an energy sobriety, a sobriety constructive and an environmental sobriety . On this building, Tradical Hemp Concrete is used for 2 applications. In a wall with distributed insulation, it constitutes the walls of the exterior facades walls street and side courtyard. It is applied mechanically in filling between slabs. It is also used in roofing with distributed insulation.
