Adria Electronic: Croatian System Present in Global Hotel Chains

As Poslovni Dnevnik/Ivan Tominac writes on the 4th of October, 2020, the director of Adria Electronic from Rijeka explained how at one address, in one company, only with their own employees and without any outsourcing, they united the development of a complete system.

Adria Electronic is based in Rijeka and its director is Vladimir Budislavic. The company took its first steps back in 1974, surviving the disintegration of Yugoslavia and 20 years ago establishing the first collaboration on the project for which they are best known today, and it is an intelligent room system in which they cooperate with the global giant Siemens.

”Back in the year 2000, we received an inquiry for the implementation of an intelligent room system at the Dubrovnik Hotel in Zagreb. The system of a foreign manufacturer was already partially installed on the newly built part, during which there were some disagreements and it wasn’t fully put into operation. Now they needed to renovate the old part of the hotel and didn’t want to continue with the same supplier, the requirement was that the system that should be installed now should work with the one already installed as one single system. For that, it was necessary to reprogramme the already installed components, write new software on the computer, but also to develop and produce all the components that are installed in the accommodation units,” explained Budislavic.

They accepted this challenge and by the end of the same year, they completed it and the hotel was put into operation with a new system, hitherto unknown in Croatia.

“We did it as a project, not even suspecting that we’d end up with a product, better to say a system that is interesting to the market. Over time, new requirements and large clients began to appear, which made us realise that we have a product in our hands that we can sell ourselves and implement directly to the user,” added Adria Electronic’s director.

In the intelligent room system, all functions are integrated into one system and thus the interaction between them and the sensor is realized. It optimizes performance in order to achieve maximum comfort with minimum energy consumption. The focus is on improving security performance, obtaining in real time all the statuses and parameters in the room and storing them in files, which will subsequently enable analysis in case of need. From 2000 until today, the system has been installed in about 600 buildings and approximately 55,000 accommodation units of hotels, apartment complexes, mobile homes and business premises. Today they are present in many world hotel chains such as Hilton, Holiday Inn, Sheraton, Radisson Blue, Kempinski Shaza, Marriott, Accor, but also locals such as Valamar, Maistra, Blue Lagoon, Liburnia, Jadranka…

”In cooperation with our customers, we constantly adapt and supplement the functions of the software and the devices themselves, adapting the design and materials to the requirements and trends of the market. Perhaps the most important thing for the final satisfaction of users in the hotel segment is quality support, 24 hours a day, 365 days a year. We’re trying to respond as soon as possible according to the priority of the application, there’s always room for improvement,” said Adria Electronic’s director, Vladimir Budislavic.

The classic way of self-control includes a mechanical key, a thermostat that locally regulates the temperature set on it, lighting controlled by classic switches, curtains, blinds or awnings that are controlled only locally, without automatic settings according to current room status. In this case, there is no sensor to control the openness of the front door, the balcony door or, for example, a room flood. In the case of an intelligent room, all components are connected to a ”room controller” which is also connected to the computers at the reception, and intelligent interaction between all sensors and set-up devices is enabled via a local programme. Such a mechanism also brings tangible financial effects with it.

“The savings on energy are obvious by regulating the temperature according to the status of the room, turning off the lighting when there is nobody in the room (thus extending the time between changes of lighting fixtures). It’s difficult to talk about exact numbers, they depend on many factors; the climate zone in which the hotel is located, the thermal insulation of the walls and glass, the period in which the room is rented, the period in which the guest stays in it. Certain savings can be achieved by analysing data from rooms and the movement and stay of staff and by optimising certain procedures,” said Budislavic. In recent years, they have also developed a lighting control system based on the DALI protocol, working on upgrading the possibility of entering a room with a mobile phone, air quality systems and various other projects.

“We applied for a tender for incentives for the development of some new products, which we mentioned previously. We didn’t pass in the first round, we gave a new request with the required corrections and we hope to pass. We are also thinking of reactivating some areas that we have left, or moving to new ones, so that we don’t depend so much on the hotel industry,” concluded the director of Adria Electronic, Vladimir Budislavic.
