An unexpected path for an engineer: he had to take over the family business, but found himself in Dubai

June 30, 2020

Globally, buildings consume about 40 percent of all primary energy, however, building technologies do not advance as fast as, for example, the car industry, IT or the financial market. "This technological gap is growing on a year-over-year basis, and there are not enough specialists to fill this gap. Historically, with short-term changes, energy prices have been rising in a consistent way, thus the need to address the problems associated with building engineering systems is also increasing. “Every day, more and more building managers or developers realize what part of their operating costs goes to building maintenance and, thus, turn to building energy specialists who have got this very specific knowledge”, says Rokas Janulis, a graduate of Vilnius Gediminas Technical University (VGTU), currently working for the company “Dubai Airports”, which is in charge of the operational management, asset maintenance and the development of two international airports.

He tells his story of how the studies chosen at VGTU Faculty of Environmental Engineering which were supposed to successfully promote the take-over of the family business, led him to Denmark and later to exotic Dubai.

Many young people find it difficult to choose a profession or an area they want to relate their future to. Have you always known what you wanted to study? What led you to the choice of the building energy?

I fully understand young people and their hesitations, because I myself was in such a situation. Only the "menu" of studies is much more extensive nowadays, and the more "dishes” you have the harder it is to choose. In 2006, it also was not an easy task to make a choice because I wanted to try different areas and activities. After long discussions, I chose the Building Energy Studies offered by VGTU Faculty of Environmental Engineering, because the business that my parents were developing at that time was directly related to this area. You probably wonder if my parents insisted on this choice.  The answer is yes, but it was not a decisive argument. I had been following my dad at work since I was a child, going to work meetings with him. At the age of 14, I already started installing air conditioning facilities for my parents’ friends. However, I did not take over my parents' business. 

What stands out in your memory from the studies at the university? 

Probably, like for most young people, student parties were exceptional events (laughs). Speaking seriously, my career in the chosen area started the other way round, i. e. first I gained practical skills and only then, when I studied at the university, did I acquire theoretical knowledge. Perhaps that’s why most of the study subjects studied then turned out to be interesting and meaningful.  Well, perhaps except maths (laughs). 

Tell us, please, about your career, professional work? 

My career path was a bit atypical, because, as I have mentioned, I started work in this area when I was a teenager. Then, during my bachelor's and master's studies I helped to develop my parents business, worked as a designer, initiated a separate business branch to implement renewable energy technologies in Lithuania. I remember that I had to contribute to the design of one passive house according to the German standard, I did the calculations. 

Tell us, please, how you found yourself in Dubai? What are the main activity areas of your company and what does your working day look like?
 
In fact, I followed my wife to Dubai because she got a job here prior of me. I currently work for the company “Dubai Airports”. The company responsibility areas are the operational management, asset maintenance and development of two international airports. So far, this is the largest organization I have worked for. I work in the Energy Management Office. The key functions of this office include the launch, development and supervision of energy conservation solution projects, development of the long-term energy strategy, implementation of new processes and standards to reduce the airport energy-related operating costs, and support of sustainable development. 

As for a typical working day, it is rather difficult to describe because there are no two identical working days. On a daily basis I have to make telephone calls, write emails, conduct or participate in meetings with other departments, address strategic issues. My responsibilities also include inspection of existing airport systems and shaping them to the most modern technologies and solutions. There is no time for boredom, and those around you always respond in a positive way to knowledge-based opinion.
  
You graduated from VGTU in Lithuania. What does the quality of Lithuanian studies look like in the international context? 

Like any other university in Europe, VGTU has a high evaluation criterion in a global context and the knowledge obtained at this university is highly valued by employers. People living in other countries may not know where this university is. However, they certainly realize that in the West, in European countries diplomas are not given for nothing and it takes a lot of effort and time to complete the studies there and get a degree.
 
In my opinion, this professional area is desperately significant and needed on a global scale. I myself have had to participate in many interviews and collaborate with recruitment agencies and staff professionals in finding specialists in other states because they are simply not available on the local market. Very often, building energy specialists have to be invited from North America, European or Asian countries, where such specialists have strong professional competencies and knowledge in the area, they are aware of the latest methodologies and technological solutions. 

Please, tell us why you like the job of an engineer and what the benefits of choosing this path are? 

Firstly, the job of an engineer, no matter what field, has always been and will always be highly valued. It is not for nothing that memos such as "Trust me, I'm an engineer” are created.  Engineers constantly deal with issues related to daily human activities, the environment, and the results of their work are usually tangible and can be measured.
 
Everyday activities, i.e. work you are doing, must be pleasant, encourage improvement and increase satisfaction with the results achieved. I would not like to urge school graduates to choose a speciality they are not interested in, but I would like to point out that the knowledge we gain in this area at the university is very necessary and valued both on the local – Lithuanian – and global levels. I can assure you that none of this field specialist will be left without work. And, with the right approach, this field specialists can become world-class coveted experts of their field.

Interdisciplinarity in practice: how Electronics and Medical Engineering students developed a Human motion analysis system
Modern engineering solutions are increasingly created through collaboration between specialists from different fields. The university environment provides an opportunity to combine diverse competencies and develop solutions that would be difficult to achieve within the boundaries of a single discipline. Such collaboration was also at the heart of a bachelor’s thesis project in which VILNIUS TECH students Laura Venckutė (Faculty of Electronics) and Abderrazak El Aamrani (Faculty of Mechanics) combined expertise in electronics and medical engineering to develop a human motion recognition and evaluation system. From an Idea to Interdisciplinary Collaboration At the beginning of the project, students from the Medical Engineering and Electronics Engineering study programmes sought to address a problem relevant to both sports and rehabilitation: the lack of accessible systems capable of automatically evaluating human movements and providing immediate feedback. As the project authors point out, incorrect movements can reduce training effectiveness and increase the risk of injuries during rehabilitation, sports activities, or everyday tasks. For this reason, they decided to look for a technological solution that could help objectively assess movement quality. The idea emerged from previous projects and experience gained during their studies, while an important catalyst was the opportunity for collaboration proposed by their supervisors. From the outset, it was clear that the project would require expertise from different fields, as motion analysis involves not only developing a technical system but also defining meaningful criteria for evaluating human movement. [caption id="attachment_120707" align="alignnone" width="2048"] Electronics and Medical Engineering students developed a Human motion analysis system[/caption] The students brought different, yet closely interconnected and complementary competencies to the project. The Electronics Engineering student was responsible for computer vision, embedded systems, and system integration, while the Medical Engineering student contributed expertise in biomechanics and human movement assessment. Although responsibilities were divided according to individual areas of expertise, key decisions were made collaboratively. From the Initial Concept to a Functional System In the early stages, the team planned to develop a system capable of analysing a broader range of movement patterns and performing more advanced analytical functions. However, as the project progressed, technical limitations, available hardware resources, and the scope of the bachelor’s thesis had to be taken into account. As a result, some ideas had to be abandoned. According to the team members, no major disagreements arose during the project. Decisions were made by discussing possible alternatives, evaluating how well they aligned with the project objectives, and, whenever possible, testing different approaches in practice. When technical and medical requirements conflicted, the team sought solutions that best balanced project goals and implementation constraints. The final outcome of the project is a human motion recognition and feedback system based on a pose estimation algorithm designed for basketball shooting analysis. The system detects a person in real time, estimates body posture, evaluates shooting technique according to biomechanical criteria, and subsequently provides feedback to the user. The Value of Interdisciplinarity and Future Opportunities During testing, the system performed better than expected. It successfully analysed the movements of users of different heights and maintained reliable performance at distances of up to 12 metres. According to the students, not only did the technical results exceed expectations, but the collaboration process itself also proved highly successful. In their view, such a project could theoretically be completed by a specialist from a single field. In practice, however, this would be difficult and inefficient. The project required both expertise in electronics and an understanding of human movement analysis. Without competencies from both fields, considerably more time would have been needed for learning unfamiliar topics and identifying appropriate solutions. Looking ahead, the students see opportunities to further develop the project by improving system stability, optimising resource usage, expanding the range of supported movement patterns, and increasing motion recognition accuracy. Although they are not yet certain whether they will continue working in this specific area, they hope to further deepen their expertise in related fields of technology and engineering. Supervisors’ Insights: Interdisciplinarity as a Foundation of Future Engineering The thesis supervisors emphasise that the nature of the project itself required collaboration across disciplines. However, the greatest value of the project lies not only in the technical solution that was developed, but also in the students’ ability to work together effectively. Professor Kristina Daunoravičienė, lecturer in the Medical Engineering study programme, notes that developing a human posture recognition and evaluation system requires both an understanding of human movement and biomechanics, as well as the ability to create a technical system capable of collecting, processing, and presenting information to the user. „The need for different knowledge and competencies made this topic an excellent platform for collaboration between Medical Engineering and Electronics Engineering students. Such projects foster not only technical solutions but also the ability to understand the logic, limitations, and priorities of other disciplines,“ says Prof. Dr Kristina Daunoravičienė. Although the students were initially unfamiliar with one another and came from different engineering backgrounds, a shared goal quickly became the foundation of successful cooperation. According to the supervisor, Medical Engineering contributed the perspective of human movement assessment and result interpretation, while Electronics Engineering provided expertise in system architecture, prototyping, and optimisation. According to Prof. Dr K. Daunoravičienė, the most important outcome of the project is not only the developed prototype and its comparison with the Xsens motion analysis system: „Equally important are the competencies of collaboration, communication, trust, initiative, and the ability to learn from one another. These are the qualities that allow good ideas to become real, functioning solutions.“ Associate Professor Dr Vytautas Abromavičius of the Faculty of Electronics also points out that in the era of artificial intelligence, technical expertise alone is no longer sufficient. Clear communication, the ability to understand specialists from different fields, and working together towards a common goal are becoming increasingly important. „This bachelor’s thesis demonstrated that our students communicated exceptionally well and were able to explain specialised professional terminology in a simple and understandable way. This mutual understanding enabled them to effectively combine knowledge from different disciplines and achieve an excellent result,“ says Assoc. Prof. Dr Vytautas Abromavičius. According to him, the need for interdisciplinary projects in modern engineering continues to grow. Every real-world product developed for the market consists of multiple interconnected components; therefore, a broader understanding of the problem leads to better product applicability and a more complete final outcome.
