Energy consumption (GJ)

Per capita consumption (GJ)

  • Distribution of energy consumptionThe 3.1% reduction in energy consumption, which all in all came to over 815,000 Gigajoules (Gj), was mainly a result of good property management, the constant monitoring and maintenance of systems, and the introduction of new technologies. Per capita energy consumption, calculated as the ratio of overall consumption to the total number of employees that work at sites monitored under the EMS, showed a 4.9% decrease, which was mainly due to the optimisation of working environments.
  • At the current time, no company included in the System produces its own energy, which is therefore purchased in its entirety from suppliers or directly from producers. In almost all countries a decision has been taken to use electricity produced from renewable sources and to decrease the use of the most highly-polluting fuels.

Electricity consumption (KWh)

Per capita consumption (KWh)

  • The objective of reducing per capita electricity consumption by 5% during the 2010-2012 three-year period was achieved with a 6.9% reduction overall. This was made possible thanks to innumerable initiatives launched at the Group sites, one of the most important being the more efficient management of the Data Processing Centre (DPC) in Mogliano Veneto, Italy. The DPC's are certainly one of the biggest sources of electricity consumption within the Group, other areas including lighting, the operating of machinery, air conditioning and, in some countries, heating.
  • In 2012 the DPC's consumed a total of 35.7 GWh (-10% compared with 2011), the equivalent of 24.3% of the total. Of the various company sites, the Mogliano Veneto Centre is the most energy intensive also because - like the DPC in Germany - it also carries out ancillary activities on behalf of Group companies located in other countries.
  • There was also a reduction in per capita electricity consumption too, to which almost all of the countries made a contribution except for France and Switzerland. The reduction in Italy was particularly significant and stemmed from three main factors: the new Programmable Logic Controller (PLC) system installed in the Mogliano Veneto complex, which makes it possible to manage lighting and heating automatically, the optimisation of the work spaces at almost all sites and, as mentioned, the more efficient management of the DPC. There was also a significant reduction in per capita consumption in Germany following the increase in size of the workforce in the buildings monitored as a result of the launch also in this country of a project to optimise spaces. On the contrary, the increase in per capita consumption in France was mainly due to the reduction of the workforce in the sites included in the EMS.

Electricity quota from renewable sources

  • In order to reduce environmental impact, the Group also made a commitment to increasing the use of electricity from renewable sources during the 2010-2012 three-year period. Thanks largely to the efforts of Germany and Italy, this goal was met quite convincingly. In Germany, certification body TÜV SÜD certifies that all electricity used comes from a hydroelectric source, while in Italy the electricity consumed at all sites is offset with CO-FER certificates. CO-FER certificates attest to the renewable origin of the sources used by plants for the production of electricity.

Heating fuels consumption (m3)

Diesel oil consumption (m3)

District heating consumption (Kwh)

 

  • 35.2% of the energy consumed at EMS sites derived from the consumption of fossil fuels (natural gas and diesel oil) and district heating to heat the work spaces. With the aim of reducing energy consumption from fossil fuels, in many Group buildings there are systems such as timers, movement sensors, external temperature detectors, thermostatic valves and thermostats for controlling the switching on/off of heating and air conditioning systems, temperature and humidity levels, and ventilation speed.
  • Natural gas is the most widely used fossil fuel by Group companies. The significant reduction in the consumption of natural gas in Switzerland and Italy in 2012 was mainly due to the introduction of a new heat recovery system at the Adliswil site and the introduction of a new Programmable Logic Controller (PLC) system at the Mogliano Veneto complex.
  • The gradual replacement of diesel oil boilers with nextgeneration condensing gas boilers is ongoing and has almost been completed. As such, the increase in diesel oil consumption in Germany is to be regarded as an anomaly connected with the increased use of the conference room at the Generali Seminarzentrum site in Bernried during the year.

The management of buildings, corporate structures and property used by third parties, in full compliance with national laws in force in the various countries, is generally delegated to representatives of the main company technical departments, who are also involved in managing health and safety in the workplace and purchases.

The management objectives of the Generali Group in the real estate sector are identical to ones it pursues in the other sectors in which it operates: growth, product enhancement and improved financial results. For this reason, the construction of new buildings and the redevelopment of existing premises are carried out with the aim of improving quality standards with a view to minimising environmental impact and consistently improving the wellbeing of those that work there.

To this end, environmentally friendly criteria are applied whenever possible, with special attention focused on energy saving, limiting greenhouse gas emissions and on the materials used. In terms of heating and cooling systems, wherever possible attempts are made to use environmentally efficient technologies such as ceiling or under-floor systems (Germany) or direct expansion systems, such as heat pumps (Italy and Germany).

In recent years there has also been greater use of building envelopes and other energy saving solutions such as insulation and thermal doors. In many offices in all countries, movement sensors or clocks/timers have been installed to control the turning on and off of lights and heating and cooling systems.

In all countries, except Switzerland, it is now common practice to replace used light bulbs with energy saving light-emitting diodes. Elsewhere, LED lighting systems have been partially introduced at some sites, guaranteeing significant advantages over traditional light sources such as greater reliability, high efficiency and a longer life.

The majority of the Group's sites have energy or sustainability assessment certification; in some cases the possibility of certifying some materials used for construction/refurbishment is also evaluated. For example, in Austria the majority of buildings have Energieausweis energy certification attesting to the energy performance of the building, while in France the majority of sites have High-Quality Environmental certification (HQE).

In Italy, France, Germany and Switzerland, various steps have been taken to reduce the amount of electricity consumed by the DPC machines. More specifically, in France the cold corridor system is used which requires the machines to be set up in a line so that only the corridor has to be cooled and not the entire room. In Switzerland, the DPC has been completely restructured with the latest IT equipment introduced in an effort to increase capacity and security while reducing consumption. To this end, the Technische Sanierung Sood Adliswil (TSSA) project was launched in Switzerland to reuse the heat produced by IT equipment - which would otherwise be dispersed into the atmosphere - using a heat pump system. During the winter months this system allows for savings of up to 75% in natural gas consumption for heating purposes.

Initiatives to reduce energy consumption in 2012
COUNTRYTYPE OF INITIATIVE
Italy, AustriaIntroduction of LED lighting at the Mogliano Veneto complex with forecasted savings of 668,000 kWh a

Italy, FranceSwitching off of servers and thin client workstations outside of working hours.
ItalyA natural gas-powered trigeneration plant is currently being developed at the Mogliano Veneto
complex (launch scheduled for April 2013 with the first 1.5 MW motor) which will make it possible
to produce combined power, heating and cooling energy. The plant will meet all of the energy
requirements of the building, equal to 18 GWh (11 GWh of which for the DPC), with annual savings
of 5.4 GWh.
