A photovoltaic roof system for the Jaén Tramway workshops and depot
In accordance with their policy of promoting public transportation, the city of Jaén, Spain has built an environmentally sustainable and efficient tramway system. For its strategic heart, the workshops and depot building, ArcelorMittal supplied Hacierco® roof decking sheets and a photovoltaic system.
With two lines, 10 stops, and 4.7 km in length, the new Jaén Tramway is designed to quickly and efficiently connect the city’s most important locations on the north-south axis and at the same time enable access to the city centre ensuring intermodality with the railway and bus interchange. Its urban integration, accessibility, intermodality, and sustainability are the principal characteristics of its implementation.
Line 1, the urban section, connects the multimodal interchange with the city centre. The interurban section, Line 2, goes past important points of interest such as hospitals, the university campus, industrial and business parks, and the future law courts complex.
Jaén Tramway system’s workshops and depot complex occupies a total area of 22 480 m². It is capable of accommodating eight tramsets under cover, but will have the potential to increase this capacity by four additional cars in the future. It is comprised of:
- a workshop and depot building housing the tram depot, the workshops, and the tramway system management and control area
- a service station
- fans of sidings
The workshop and depot building is a strategic facility that houses the control room from which all Jaén Tramway operations are managed in real time. The project consists of a single large 6970 m² building comprised of one level divided into three zones: the workshop, warehouses, and the locker room, control room, and administration area. The workshop includes a painting and wheel turning line, bogie maintenance, two maintenance lines, cleaning line, and sidings. The warehouse area is divided into two main zones: the fixed installation warehouse and the rolling-stock warehouse. The administration area is situated around a courtyard with a U-shaped corridor that gives access to the various rooms, canteen, and locker room.
The entire building is built with a metal frame in grade S275 steel. Subdivided into six bays (designated A to F, as shown in the drawings), all are designed with portals comprising IPE beams and HEB columns (IPE columns for the facade portals) that support a roof with IPE purlins. The bracing, both on the facades and in the roof, consists of angled sections.
The service station is located at the site entrance. It is a large container with a lower height in one corner and is coated with weathering steel which can be extended in the future for administrative use.
ArcelorMittal supplied Hacierco® 4.250.46 D profile as roof decking and a photovoltaic system for the roof comprised of 234 Suntech STP-24 Vb modules in 18 chains of 13 modules in series with 9 SMA Sunny MiniCentral 7000 TL inverters giving an installed capacity of 65.52 kWp.
