Energy-intensive building

In 2014, aware of the renovation work to be done on their building, the union council decided to carry out an energy audit. Oriented by GPSO, he is moving towards a global audit of their residence.
Following this audit by Reanova, the condominium decided to carry out a design mission for one of the scenarios.

This scenario includes:

  • the thermal insulation of the facades from the outside
  • insulation of low floors
  • the establishment of a humidity-sensitive type B ventilation
  • the passage of fuel oil to gas
  • the installation of thermostatic faucets
  • the replacement of the original private joinery
  • lighting common areas

With an energy gain of 58%.

After the design, the condominium voted the completion of the work in 2017.

It is a global and ambitious renovation project , with thermal insulation of the building (external walls, floor, windows) but also a renovation of the systems (boiler room, terminal regulation, ventilation). This works can achieve up to 58% energy savings.

The approach initiated by the condominium is also exemplary. From the energy audit to the works. A thoughtful and coherent approach from the beginning to the end.

Sustainable development approach of the project owner

For many years, the condominium complained of problems of air leakage around windows and difficult heat regulation. As part of the energy and architectural audit of the condominium, a survey of the occupants was carried out in 2014, identifying the precise expectations of the condominium on the renovation of their building. It confirmed the strong expectations concerning the improvement of the thermal comfort , but also the control of the consumptions of energy .

In October 2015, an extraordinary general assembly voted on the design mission and retained the most ambitious scenario proposed following the energy audit, to reach the BBC renovation (building low energy consumption) level, set at 104 kWh / m² / year. in Ile de France. The result should eventually reach 97 kWh / m² / year, which makes the condominium class E to class C, allowing a saving of nearly 60% on energy consumption.

Architectural description

The condominium Les Vignes is composed of a building (R + 13) and 58 dwellings. It dates from 1963.

The works carried out are:

  • Thermal insulation from the outside with 14 cm of rockwool
  • Insulation of low floor with flocking of 12 cm mineral wool
  • Replacement of joinery in single glazing by double glazed PVC joinery
  • Installation of a gas condensing boiler instead of a fuel boiler
  • Installation of a humidity-controlled type B ventilation
  • Modernization of the lighting of common areas (LED + detectors)

    Work on the insulation of walls and joinery has, among other things, increase the thermal comfort of occupants by eliminating the phenomenon of cold walls in winter and limiting overheating in summer. In addition, the improvement of the ventilation makes it possible to ensure a renewal of air all the year, that further improves the comfort of use of the building.

Reasons for participating in the competition(s)

Il s'agit d'un projet de rénovation globale et ambitieuse, avec isolation thermique du bâtiment (murs extérieurs, plancher, fenêtres) mais également une rénovation des systèmes (chaufferie, régulation terminale, ventilation). C’est travaux permettent de réaliser jusqu'à 58 % d'économies d'énergie.

La démarche entamée par la copropriété est aussi exemplaire. De l'audit énergétique jusqu'au travaux. Une démarche réfléchie et cohérente du début à la fin.
