+ Adoption in 2012 by the Ile-de-France region (surrounding Paris) of a strategy for improved energy management, the development of local and renewable energy sources and the reduction of the housing and service sectors’ contributions to global warming
11/06/14 2 Presentation of CPCU
Buildings in France : No. 1 contributor to energy consumption
> 43% of total end-use energy consumption (and 2/3 for heating)
> 25% of CO2 emissions
> 70% of city infrastructure in 2050 already exists today (in 2050, it will remain between 30 et 40% of housing built before 1975)
Specific context of Paris and its suburbs…
• Very high urban density • Old buildings with little insulation (75% of buildings in Paris were built before 1914)
…and increasing regulatory requirements • RT 2012 (French environmental legislation for the housing sector) : thresholds of 50 kWh primary energy/m²/year for new buildings 150 kWh primary energy/m²/year for structural renovation
CHALLENGES > Demands of an urban context Increase building energy efficiency

CPCU PROJECTS > Coal / Biomass Co-Firing
Saint Ouen II plant:
Storage silos + new biomass conveyors
Storage capacity : 2 x 1 500 tons ~ 2 days of supply at 50%,
feed capacity : 60 t/h
New logistics:
rail unloading station New storage : coal (2000m3) et biomass (4×1600m3)
Truck contingency site
Heating hangar
New rail way
New underground conveyor
Ø Objectives :
• Integrating new renewable energy in CPCU mix energy
• Urban integration of CPCU Saint Ouen Site
Ø Expected Commissioning in 2016

CPCU PROJECTS > PNE Project
Ø Project initialized under a large program in uban renawable of the north east of Paris
Ø Concept based on a heat & cooling district with geothermal power (dogger, 1800 m) and realized by a partnership CPCU / Climespace
Ø Started in 2010, commissing in 2013
Ø Underground geothermal power station of 1200 m2 (on 3 levels)
Ø Production :
Heat power : 94 MW (geothermal : 18 MW) Expected consumption : 144 GWh/an
Cool power : 6.6 MW (+ 10 MW) Expected consumption : 30 GWh/an
Ø Energy benefits
Renewable Energy rate : 60%
GHG saving : 17 500 tons/year
CPCU PROJECTS > CO2 EnergiCapt Project
11/06/14 11 Presentation of CPCU
Ø ANR R&D project : Energetic integration on existing heat plant of CO2 capture, based on membrane technology
Ø budget: 4,1 M€ (ADEME : 1,3 M€)
Ø Partners : LLT (coordinatoor), LRGC, Polymem, CNRS, CPCU
