The Retrofitting Programme

>> Cotentin-Falguière Residence 1

Reminder of the retrofitting stakes Patrimonial stakes - bring the building to current safety and comfort standards - improve the building’s thermal performance and limit consumption - highlight the building’s strengths - adjust the housing supply to the needs of SNCF staff Tenant stakes - improve the comfort and living standard of dwellings - limiting expenses related to energy consumption

2

The project in figures Number of dwellings: 86 before, 82 after retrofitting Estimated duration of work: 18 months Total cost of work: about â‚Ź 6 million (excl. European subsidy) Cost of work per dwelling: â‚Ź 70 000 (excl. European subsidy) No rent increase after the works A 50% share of the cost savings achieved between landlord and tenant (MOLLE Act of 2009)

3

A European project BEEM-UP: a European Union initiative 3 pilot sites: Alingsas (Sweden), Delft (Netherlands) and Paris (France)

Exchange of practices and ideas among donors, builders, consulting firms, manufacturers and universities from many countries A subsidy for energy saving works Multiple common objectives

Energy consumption reduced by 75% Use of innovative technical solutions Special attention to the support of tenants An long-term approach (performance and consumption monitoring)

4

Tenant support Support before and during the works Relocations of tenants of the apartments converted into duplexes Development of buffer apartments to provide rest areas during the works Support for the relocation of tenants who are permanently leaving their homes Consultation with tenants: the result “Outer spaces” workshops: “Zen“atmosphere, more room for bikes “Energy saving” workshop: a charter of "green behaviour" in preparation 5

Facilities are old, but still usable: targeted interventions

Electrical facilities are old, composed of obsolete materials and equipments (ceramic or metal switches, insufficient safeguards on the switchboard, fabric wiring): bringing into full compliance of facilities

Securing the facilities Replacement of switchboards Replacement of original or degraded equipments and materials Electrical outlet complements, especially in the kitchen and living room (if full compliance)
