The Situla building, Ljubljana

DEVI solutions for ultra-modern design

The Situla building is a uniquely-designed construction complex, which extends over 80,000 m2 of overhead areas and has a variety of uses.

Underground parking

The 72-metre high residential tower contains 20 floors connected to the base by an 8-story tower extending along the entire building plot. A wide range of apartments was designed in the building: small single studios, medium-sized family apartments, duplexes, atrium apartments with patios, and also lofts.

The Situla contains 226 apartments, more than 6,000 m2 of office facilities surface, and more than 5,000 m2 of service establishments. The underground parking garage can hold 856 cars.

DEVI solution

Considering the comfort and safety of exploring the Situla building, DEVI was chosen to protect the roof, gutters and down pipes as well as the ground around the parking entrance. Thanks to simple and effective DEVI electric heating systems, the roof, the drain system, and the parking entrance of the Situla stays free of ice and snow during the winter.

Project overview


Heating cables
The DEVIpipeguard™ is a self-limiting heating cable that is mainly used for frost protection of pipes. The self-limiting capability of the cable ensures that the output of the cable increase or decrease according to ambient temperature. The cable will maintain its functionality even when shortened. The polyolefin outer sheath is highly resistant to harsh environmental conditions and corrosion and it also serves as a protection against mechanical influences.
DEVIsnow™ is an extremely high-quality, 360° fully screened twin conductor cable with a tough outer sheath (UV stable). Its round profile and robust construction ensures a fast, simple and safe installation on roofs, in gutters, down drain pipes and on the ground. The cold lead has solid conductors ensuring fast installation with a clearly visible connection. To ensure a long life-time, all cables are minutely inspected including tests for Ohmic resistance, high voltage and material controls to ensure the quality. This means that we are proud to supply our extended DEVIwarranty™.
The DEVIreg™ 530 is a simple electronic thermostat with a 2-pole switch, using a floor sensor (wire) to measure and control the desired floor temperature. It can be either flush-mounted or surface-mounted. The thermostat has a dial for adjusting the temperature setting with a scale from to 6. Furthermore, the thermostat has an LED indicating the current mode (heating, standby or fault).
The DEVIreg™ 850 is an advanced thermostat with LED display used for outdoor ground or roof applications. The sensors provide information about both moisture level and temperature, resulting in an optimal control of the heating system. The system can be set up in three ways; as a single system for roof or ground (1 to 4 sensors), as a dual system for roof or ground (2 - 4 sensors) or as a combination system for roof and ground (2 - 4 sensors). In the dual / combination systems it is possible to prioritize between the zones, e.g. if only a limited power output is available.
