Transports infrastructures

The energy guzzlers...

Airports and train stations are by their nature largely open buildings and whose energy losses can be colossal. Activities as varied as passengers, freight or industrial and equipment maintenance activities also have different specifications, particularly for the notion of comfort for travelers so as not to affect their experience and encourage attendance.
Energy sources are also numerous and their distribution spread over large areas: hot water, cooling water, drinking water, gas and other petroleum derivatives, low, medium and high voltage electricity, cogeneration, solar self-production, wind turbines, pumps heat, compressed air, etc. all present opportunities for substantial savings and gains by identifying losses and providing a good overall view of energy expenditure.
Two aspects are predominant:
– The colossal consumption of facilities such as stations and airports: Aéroports de Paris, which manages the Charles-de-Gaulle, Orly and Bourget platforms, bought 488,427 MWh in 2013 (source
– The service obligation which also entails a significant cost because any “black-out” is strictly prohibited. Imagine a control tower or traffic management posts suddenly without power as planes are approaching…
For stations, the example of the SNCF speaks for itself: The group is the first industrial consumer of electricity in France with more than 9000 GWh per year, i.e. approximately the production of a nuclear power plant, 81% of which is for the traction of 15,000 trains operated daily, 16% to operate buildings (stations, offices, workshops, etc.) and 3% for the road (mainly service vehicles).
After the renovation of the St Lazare station in Paris, energy saving measures led to an immediate saving of 20% of the electricity budget devoted to the building (excluding traction energy).

The report “IMPROVING ENERGY EFFICIENCY AND REDUCING EMISSIONS THROUGH INTELLIGENT RAILWAY BUILDINGS” by ASIAN DEVELOPMENT BANK on the management of stations in the People’s Republic of China proposes 4 measures allowing an energy saving of 14.47% from an average energy performance of 307 kWh/m2/year to 127 kWh/m2/year.
– Management of cooling pumps 100% variable according to the pressure drop in the closed loop and the chilled water outlet temperature. This measure saves 3.87% of total energy.
– Air conditioning system with variable air volume according to the measurement of attendance. This measure saves 5.01% of the total energy.
– Heat recovery from fresh extracted air. This measure saves 2.86% of the total energy
– Control of natural lighting and adjustment of artificial lighting by dimmable ballast. This measure saves 4.82%

Stations and other transport-related infrastructure have a definite advantage over all other buildings thanks to a rate of automation and supervision equipment much higher than all other tertiary buildings. Indeed, the obligation of continuity of service on heterogeneous or even heterogeneous infrastructures and on gigantic surfaces, have long led these organizations to automate. This is the gold mine that SILENO e3m needs to help you manage your energies. The EMS SILENO e3m has all the software connectors to draw directly from the installed equipment all the information necessary to build a cross-sectional view of your installations.

Deploy the latest technologies in the oldest infrastructures

Deploy the latest technologies in the oldest infrastructures

Stations and airports are gigantic installations that have been developing for decades.

New buildings and installations, renovations of the oldest buildings, but there are rarely programs to bring all the technical installations up to the same level.
Operators therefore have to deal with sometimes huge technological gaps between different generations of management, automation and supervision systems.
SILENO e3m and the supervision software offered by SILENO represent an experience of more than 30 years and an incalculable number of connected devices from which e3m draws data.
From the oldest protocols to the most recent technologies, e3m is a system with very high cognitive power providing communication to the oldest automation, up-to-date interfaces such as BACnet, OPC DA/UA but also the latest interfaces for IOT equipment such as NODE-RED, LORA, SIGFOX, NB-IOT and more.

Satellite 3 at Paris-Charles de Gaulle international airport has 8.5 million passengers per year for an area of 225,000 m2 on 7 levels.
It was equipped in 2011 with SAUTER EMS (OEM version of SILENO e3m). This investment alone enabled 38% savings on heating production vs. 2010 (Source Sauter Magazine)
