Aleja shopping centre

Aleja with its 32,000 square metres houses 80 stores, offering a wide range of brands. The shopping centre spreads over three floors with two underground garages. The total investment in the project was more than EUR 150 million.

The electrical infrastructure in the building uses Hermi cable systems. In total, there are 14,500 metres of cable trays along with load-bearing and all accessories as well as 1,700 metres of type “E90” fire-resistant cable trays.

The green roof of the building features sports fields and a running track. A properly installed lightning protection equipment that also maintains the building’s aesthetics and appearance was necessary to ensure compliance with the lightning protection standards and the safety of visitors. An ISVH insulated lightning conductor was used in combination with the IZO60 insulated supporting post to protect the sports field and the track. The number of posts required was optimised by calculating the area of protection using the SHIELD software. We ensured an adequate protection of the building with the air-termination system using the rolling ball method and found the optimal solution with the help of the SHIELD software.
