For some years now, the ENAV Group has launched a series of activities aimed at monitoring their consumption more precisely in order to reduce the impact of greenhouse gas emissions and the costs associated with them.
As recalled in the Code of Ethics, the Group, in full compliance with the current environmental legislation, pays particular attention to the promotion of activities and processes that are as compatible with the environment as possible, through the use of criteria and advanced technologies in the areas of environmental protection and the sustainable use of resources. The Group, therefore, undertakes to consider, in the field of operational management and business initiatives, essential environmental needs and to minimise the negative impact that its business activities have on the environment.
CONSUMPTION OF THE ENAV GROUP IN 2017
AIR FLEET FUEL (decreased by 6% compared to 2016)
FUEL FOR OFFICES AND FACILITIES (decreased by 14% compared to 2016)
ELECTRICITY FOR OFFICES AND STRUCTURES (decreased by 1% compared to 2016)
THE CONSUMPTION OF DIESEL HAS DECREASED COMPARED TO 2016 (while the consumption of petrol and CNG has increased by virtue of the purchase of new hybrid cars)
CAR FLEET FUEL (4% increase comprared to 2016)

Regarding this consumption and the resultant impact on the environment, in ENAV, the figure in charge of identifying actions, interventions, procedures and anything else necessary to promote the rational use of energy, is the energy manager.
It must be remembered that all the sites of the ENAV Group, the Towers (TWR) and the Control Centres (ACC), the radar sites, the TBT radio centres, the runway lighting systems (Luminous Visual Aids) and the radio assistances are powered by electricity and by electrogenerating groups with automatic intervention (GEIA) that supply electricity only in cases of black out of the primary energy source and are fuelled by diesel. Given this, the ENAV Group, has already for several years taken care to ensure that all GEIA are included in the list of assets with little significant pollution (listed in Annex I to DPR 25/07/91).
Following the energy Audit pursuant to Article 8 of Legislative Decree No. 102/2014, certain interventions to improve energy efficiency have been identified, and several initiatives have been launched:
- the replacement of all fluorescent lights with LED lights with related domotic control and regulation (ACC Rome and Padua, Rome headquarters);
- the construction of a high-efficiency trigeneration plant for the production of electricity, hot and cold water for the air-conditioning of the equipment halls and offices of the ACC in Rome;
- the construction of new photovoltaic systems for self-consumption at the airports (CA) of Bologna, Palermo, Crotone, Pescara, Brindisi, Lampedusa and at the radar site of Monte Stella;
- the construction of new automatic power-factor correction systems (Rome headquarters and other Airport centres). The power-factor correction of the installations has gained importance because the electricity distributor has imposed contractual clauses through the CIP tariff measures (No. 12/1984 and No. 26/1989) which, in fact, oblige the user to correct its installation’s power-factor for a better and more economical use of energy; 5. the construction of new air conditioning systems with heat pumps and Free Cooling; 6. installations for measuring and monitoring systems for energy efficiency;
Moreover, in anticipation of the possible future use of electric cars also for the company fleet, chargers have been installed in the offices of Ciampino, Bari, Naples, Brindisi and at the headquarters.
The most significant investment is that made for the use of photovoltaics: the photovoltaic Control Towers of the ENAV Group (the first in Europe) and all the other initiatives, are in fact the result of a programme in continuous growth determined a substantial reduction of energy costs, also benefiting from state incentives.
THE PHOTOVOLTAIC INSTALLATIONS OF THE ENAV GROUP
The photovoltaic tower of Bari Airport
All the operating systems of the Bari TWR are powered, during the day, by a photovoltaic installation positioned on a large roofed car park. The 100KWp installation satisfies about 1% of the daily needs of the structure and receives an incentive on the production of energy of 0.202 euro/kwh with an estimated production of about 100,000 kwh/yr. The primary energy saving is 26 TEP/yr with a reduction of 76 tCO2/yr.
ENAV Headquarters in Rome
The building that houses the headquarters has a photovoltaic installation with a power of 80 KWp, installed on the roof. The system consists of 336 modules of 240 w each in polycrystalline silicon with an estimated production of over 88,000 KWh/yr and a primary energy saving of about 0.3%. The primary energy saving is 20 TEP/yr with a reduction of 60 tCO2/yr.
The photovoltaic tower of Ancona-Falconara Airport
The tower of Ancona-Falconara produces clean and incentivised energy. The installation was built in 2008 on a shelter with a power of 43 KWp. It was the first airport photovoltaic installation, and it receives an incentive of the 2nd Energy account issued by the Energy Service Manager (GSE) of 0.36 Euro per KWh produced, to which is added a further economic benefit of about 0.20 Euro kWh thanks to the savings in consumption of electricity produced and not taken from the network. The primary energy saving is 11 TEP/yr with a reduction of 32 tCO2/yr.
The ACC photovoltaic installation contributes to powering all operating systems for air traffic control with clean energy.
It has a peak power of 63.36 kWp with an estimated output of about 88,700 KWh/yr. The photovoltaic modules have been installed on the roof and on a roofed car park; also in this case ENAV receives an incentive from GSE on electrical production. The primary energy saving is 16 TEP/yr with a reduction of 48 tCO2/yr.
This installation was constructed near the radio beacon at the Bari Airport, in Bitonto, with a capacity of 100KWp. It was built to power the NDB site and the electricity produced in excess of the requirements, is placed in the electricity grid through the “Exchange on the spot” contract. The primary energy saving is 26 TEP/yr with a reduction of 76 tCO2/yr.
Finally, in 2017, the photovoltaic installation was completed (currently being tested) for the Naples C.A., 77KWp for self-consumption and the photovoltaic installation cabin AVL AC 5, 5kwp was built pursuant to Legislative Decree No. 28 of March 3rd , for new buildings.
CO2 EMISSIONS AVOIDED, THANKS TO THE PRODUCTION OF ENERGY FROM RENEWABLE SOURCES
Given that a photograph related to all fuel consumption is reported at the bottom of this document by means of a list of the GRI Standard indicators, in this area the policies and initiatives concerning the impact of the ENAV Group’s air fleet deserve special attention. In recent years, in fact, an important fleet renewal operation and an adjustment of operating procedures were completed with an investment of approximately EUR 35 million.
The entire fleet, consisting of four Cessna C550 aircraft, has in fact been replaced by four Piaggio P180 aircraft. This has led, in the years in which the aircraft transition was made, between 2009 and 2013, to a reduction in fuel consumption per hour of flight time of about 15%, while the average duration for each single radio navigation verification has gradually decreased by about 50%.
In 2017, the fuel consumption of the radio navigation air fleet, for jet fuel engines, was 705,000 litres, with a consequent emission of KgCO2 equal to 1.79 million.
