Energy-intensive building

Thermal renovation and bringing into conformity, in an occupied environment, of a residence consisting of a high-rise building in R + 29 with 203 apartments and two buildings in R + 14 with 232 apartments located respectively at 14, square dunois and at 183- 185, Chevaleret street in Paris, 13th arrondissement.

The ambition of the program, thanks to financial support from the City of Paris, was to meet the objectives of the Climate Plan by significantly improving the energy performance of buildings (work aimed at energy savings and reducing the production of greenhouse gases) as well as improving the comfort of housing and the living environment of tenants. The work included the installation of efficient exterior joinery, exterior insulation and roof terraces; the renovation of the networks (EF DHW supply, waterfalls, electricity and the ventilation system), the safety or complete repair of the electrical installations of the apartments, the repair of the wet rooms according to the inventory, the replacement of the landing doors, the renovation halls, and common circulation, the redevelopment of outdoor spaces. The work also related in part to equipment relating to fire safety.

Owner approach of sustainability

The main objectives were to improve the energy performance of housing and to include the project in the Climate Plan of the City of Paris by the insulation of roofs, facades, balcony surfaces, replacement of joinery and renovation work. ventilation. In addition to these aspects of energy rehabilitation, the objective was to improve the comfort of the accommodation: installation of blackouts, replacement of landing doors, fire safety (in particular of the Mykérinos IGH tower), compliance of electrical installations, works in damp rooms.

Architectural description

The aim is not to modify the architectural aspect of the tower. A pigment study was carried out to find the initial color of the tower.

The copper cladding on the gables of the "low" buildings creates a strong signal on the Chevaleret street.

Building users opinion

Consulted in 2015, tenants who spoke voted 90% in favor of its launch.

Energy consumption

  • 55,00 kWhep/
  • 195,00 kWhep/
  • RT existant

  • 145,00 kWhep/
  • The consumption of Ep announced is that of the Mykérinos tower.

    The real consumption for a full year has not yet been established, the end of the work having taken place in 2020. The initial consumption is evaluated on the basis of the thermal calculation so as not to overestimate the expected energy savings (consumption observed before rehabilitation of around 400kWhep / m²).

Envelope performance

  • 1,35 W.m-2.K-1
  • 0,70
  • EN 13829 - n50 » (en 1/h-1)

    On the tower, the fins could not be over-insulated to preserve the architecture of the building. The envelope was improved by the replacement of the milled facades, the insulation on the underside of the balconies and the insulation on the roof. Insulation from the outside for buildings K and L, on the 4 facades and green roofs. Flocking on the underside of all low floors.

Health & Comfort

    Shutters have been installed on the IGH tower for the bedrooms and living rooms (and for the kitchens facing south only), which ensures better summer comfort.

    Also, the roof of buildings K and L was insulated with the installation of a greening which allows a better comfort of summer for the dwellings on the top floor.

    Noise exposure class: BR1.

Construction and exploitation costs

  • 22 854 000
  • 6 183 000

Urban environment

The buildings are part of a larger whole, a joint ownership unit linking Chevaleret street and Dunois street.

The operation made it possible to requalify the feet of buildings around the three buildings belonging to Elogie-Siemp, with 245m² of greening on the ground, 895m² of vegetated roofs and 1,770m² of greening on the slab serving as roof for the parking levels.

The choice of plants and the installation of birdhouses (swallows, sparrows, redstarts, wagtails, chickadees, black swifts, depending on the site exposure) provide support for biodiversity in this very dense neighborhood .

Building Environmental Quality

  • biodiversity
  • energy efficiency

The rehabilitation has reduced energy needs by more than 60%, by working mainly on the building envelope (heating being managed as part of the general condominium).

Vegetate the feet and roofs of buildings (chevaleret) as well as the slab that covers the car parks.
