Completion of 29 low consumption (BBC certification) social housing renovation in a XVII century building in Lille: Hotel du Lombard.
"We will achieve 29 units, from one to five rooms, 30% of low-cost social housing (PLAI), said Alain MONTAGU, director of the company's assets. The energy component is as well a strong point of the project; a wood pellet boiler that will cover 100% of needs with renewable energy, the energy performance of Lombard Hotel will be less than 58kWh / m2 / year; and the renovation will be certified Low Energy Consumption Building (BBC renovation).

Owner approach of sustainability
The criteria for contributions and free natural light was insufficient on the Lombard site given the orientation of the building, the positioning of windows and thick walls which greatly reduce the possibilities of solar production. Envelope performance criteria and renewable energy were thus privileged, notably through the adoption of a collective wood boiler. Thermally, the main challenge will be to ensure good air seal to prevent heat loss.
-The external woodwork must have a good performance while maintaining their original appearance. Some will be lined with new joinery inside.
The facades and roofs have been restored by "DRAC, ICF NORTHEAST HABITAT" and seeks to completely transform the building, currently composed of several large trays. The building has typical floors very open based on repetitive frame which allows the installation of large typologies in the early levels.
The 29 units are divided into 11 (1room), 2 (2room), 8 (3room), 7 (4room), 1(5room). Large areas are provided on the first three levels, while the type 1 units will be grouped on third floor.
If you had to do it again?
Renovation, particularly in "energy efficiency" is a central strategic concern of the group Rabot Dutilleul. Other projects, not exactly in patrimony, are already achieved this level of performance.
Building users opinion
During the inauguration, representatives of the municipality of Lille - Audrey Linkenheld, MP - delegated municipal councilor in Lille plan habitat, Estelle Rodes, deputy mayor in charge of the relationship with social landlords, Franck Hanoh, Deputy Mayor in charge of security, Chairman of the Centre neighborhood council, Bernard Charles, deputy mayor in charge of employment and inclusion and Julien Dubois, deputy mayor in charge of heritage - were able to visit a 5room apartment.

She recalled "the importance of keeping families in the city center"; After this short ceremony, elected officials and representatives of the landlord went to visit the residents. Among them: Sonia Rainaud. Since she moved into one of the apartments of the residence, she is in heaven! Her new home is much more spacious than the one she occupied until 20 February. "Today, my family has four rooms for a living, she says. Before, I only had two rooms for me and my five children"; Additionally, her salon is crossed by a brick wall, a remnant of the former hotel of Lombard. (source, The Northern Voice, 24.4.2015).

Problem of airtightness by working only on the outer vertical walls. Must be sealed housing to housing and therefore also deal with each other. With the configuration of the existing floor (wood flooring + insulation + concrete slab) it is difficult to ensure a complete seal. Leaving the beams is also a great source of leakage and thus to treat. DESCRIPTION OF SOLUTION: to connect the vertical membranes plasterboard ceiling by playing the role of tight barrier plasterboard ceiling. It must be scrupulously rigorous on its application and on the junction of these positions. Ask waterproof electrical boxes. The shear walls are also great sources of leaks and thus treated by the projection of a aéroblue. To the junction with exposed beams, again you have to be very careful about applying a seal between the support rail and the beam and rail and also placo. Attention to all sanitary and electrical penetrations.
