UNIBAIL-RODAMCO /// ANNUAL REPORT // VALUES / SUSTAINABLE DEVELOPMENT
Lighting
The main levers for reducing electricity consumption for lighting
consist in promoting widespread use of low consumption light
bulbs and building control systems to control lighting areas and
time periods.
• In Donauzentrum, in Central Europe, 95% of lighting uses
low-energy bulbs and building control systems have been
installed in public areas and at entrances.
• In France, a programme has been launched to replace all
burnt-out light bulbs by low-energy bulbs.
• In the Nordic Countries, building control systems have been
installed in most shopping centres.
Heating and cooling
The main levers for reducing energy consumption in heating and
mechanical ventilation consist in:
• lowering interior temperatures in winter and accepting slightly
higher temperatures in summer;
• using natural ventilation for cooling
- in France, free cooling is practiced in most of the shopping
centres.
- in France, an incentive contract providing for fl at-fee invoicing
of annual consumption for urban heating as well as air
conditioning was adopted at the Part-Dieu shopping centre
in Lyon. These projects, designed to encourage an energy
savings approach among tenants, will be extended to other
shopping centres.
- in Spain, Parquesur shopping centre windows open
automatically at night to benefi t from cooler temperatures.
- in Central Europe, natural ventilation systems are used in all
the shopping centres;
- in the Nordic Countries, a system for recycling air has been
installed in all shopping centres.
Use of green energy
The Group promotes the use of green energies such as solar,
photovoltaic and trigeneration at its existing assets and for all
new projects:
• In France, a vertical axis windmill was installed at Vélizy 2,
following the example set by Carré Sénart, where the Group
installed the first windmill at a shopping centre as early
as 2001.
• The installation of photovoltaic panels has been studied at
Labège 2 in Toulouse and at Porte de Versailles and investment
programmes are now being examined.
• In Spain, green energy is widely used: photovoltaic panels have
been installed at the Vaguada shopping centre.
• In 2008, new initiatives were developed, including modernisation
of hydraulic systems for cooling, cogeneration and widespread
introduction of photovoltaic panels. The study underway shows
a reduction of 2,360 tonnes of CO 2
emissions.
Reduced water consumption and waste management
The main levers for water consumption reduction lie in:
• reusing rainwater;
• adapting installations to reduce water consumption.
- In Donauzentrum in Vienna, rainwater is collected and reused
for toilets and watering plants.
- In Spain, water consumption was lowered by 2% in 2007. The
target for 2008 is to cut consumption by an additional 10%.
- In France, Unibail-Rodamco is currently working on the
possibility of installing equipment for rainwater recovery at
its French centres.
In all the regions, the Group is pro-actively engaged in waste
sorting and has launched programmes to reduce the volume of
waste:
• In Donauzentrum, an eco-friendly business plan was presented
to the city and implemented.
• In France, hand dryers have been installed at all shopping
centres to reduce paper consumption.
• In La Vaguada in Spain, 3,558 kg of batteries were collected
using dedicated containers installed in 2007.
• In the last few years, Unibail-Rodamco in the Nordic Countries
has been putting strong emphasis on waste management and
energy effi ciency with very signifi cant results.
