Opis: This study, conducted among 596 employees across various industries, investigates the interplay between personal sustainable lifestyle scores and corporate sustainable business practices, including energy consumption and renewable energy use. The research reveals a strong correlation between individuals’ personal sustainable lifestyles and their organisations’ sustainable business practices. Notably, employees consistently practising personal sustainable behaviours, including energy efficiency, tend to work in companies with robust sustainability initiatives and low-carbon strategies. Women, in particular, displayed higher engagement in sustainable behaviours. Age-related trends suggest younger employees prioritise corporate sustainability policies more than older counterparts, who focus more on personal sustainable behaviour. Among all studied sectors the production sector stands out for its high sustainable lifestyle and sustainable business practices, reflecting the impact of industry-specific sustainability trends like lean and green operations. On the one hand, sustainable lifestyle involves making choices and taking actions that enable rational consumption of goods and products, protecting natural resources, using renewable energy sources, and utilising low-emission transport means. These findings underscore the critical link between personal sustainability habits and organisational sustainability business practices, highlighting a significant avenue for promoting sustainability and reduced energy consumption in the workplace and at home

Opis: Logistics and transport are major sources of energy consumption that still rely heavily on fossil fuels. Especially in the freight sector, finding means to optimise fuel consumption and energy efficiency are increasingly important. Digital twins’ adaptation in logistics and transport is not as frequent as in production, but their implementation potential is immense. This technology can replicate real environments, allowing verification of various scenarios without real-life application, leading to optimal implementation outcome faster and more efficiently. This paper aims to research digital twins’ use in logistics and transport, focusing on digital twins’ potential and effects to optimise energy consumption. Firstly, previous research on digital twins in specified fields was identified, followed by a quantitative literature review. The latter focused on codifying the selected publications based on criteria such as modality, specific environment, energy consumption, etc. Furthermore, a qualitative overview of 57 relevant publications on digital twins’ use in logistics and transport was made. The main contribution of this paper is the systematic overview of digital twins from the viewpoint of energy optimisation in one of the most energy-dependent sectors. This gives researchers a good starting point for further research and digital twins’ practical implementation cases.

Opis: This master thesis describes the development of smart electricity energy meter on the ARM platform. In general, the commercial electrical energy meters are measuring only the total active energy, therefore, users cannot also monitor other important power consumption parameters. The goal of this thesis is to develop a prototype of smart ARM based energy meter, which is capable to measure several power consumption parameters and display them on a webpage in real-time. In the thesis the complete design of the ARM based smart energy meter is presented in detail. Further, the development of user interface for displaying measured data on the webpage in real-time is also presented. These results are presented both in textual and graphical form. Additionally, the theory of electric power consumption measurements and some commercial energy meters are presented.

Opis: The problem we referred to is great and mostly uncontrolled energy consumption in the public and private sector not just in Slovenia but also in other countries around the world. In Europe some restrictions were met, which resulted in 2009 in a new standard, the EN 16001:2009, two years later the International Standardization Body issued the ISO 50001:2011, energy management standard. With the help of a case study potential in energy and emissions as well as overall environmental protection was presented. All anticipated research methods were followed, hypothesises set in the introduction were carefully researched and mainly proven to be right whereas some, hypothesis one and two, connected with the increase of energy consumption in Slovenia and hypothesis two, number of certificates per capita, were refuted. The overall consumption of energy in Slovenia decreased (table 2, page 15) in the year 2011 compared to 2010. Slovenia is also not the country with the lowest number of issued energy certificates per capita; Portugal has two (picture 1, page 35). Hypothesises three to five linked to the study case were fully proven to be right; the company did not have an energy management programme but the owners were fully aware of the possibilities of energy savings. There was as well energy savings potential, proven to be even more that the first anticipated 50-percent. Our conclusion is that energy management plays a key role in sustainable development and environment conservation practices, as it helps the country move towards an energy efficient economy. With the help of the case study we made a good illustration how a micro company saved 75-percent of energy costs in the first year, by using energy management as a tool. The main and general changes enhanced the company’s energy efficiency, taught employees some basic techniques for achieving greater energy efficiency and cost reduction not just inside the organization but also in family homes. It is important, that expenditures concerning energy purchase and consumption are exactly defined. Before the implementation and certainly after it, energy management accounting and energy management audits should be performed. This serves as a tool to realize and understand the full spectrum of the environmental costs and helps to create internal demand in businesses for cleaner and less wasteful production processes. It gives organizations a preferential position to engage in pollution prevention activities mainly because it makes good business sense due to the immediate financial benefits it delivers. The prime goal of the thesis was to stimulate organizations to implement the concepts of energy management practices into their organizational structure and to use energy management systems for lowering energy and other environmental costs, no matter the size or segment the organization. There is no need to get certified if not wanted; just performing these activities is enough, as it brings all the benefits to the environment. Helping to achieve this goal is now mainly in the hands of others, it is important how the country will act and react and help organizations to achieve this goal. Different restrictions can be met on the field of law and taxes, subsidies, etc. We believe that, for meeting all the required goals (Kyoto protocol and other) and help the economy to move towards a sustainable one, organizations will have to reorganize their structures and implement energy management. There are big potentials in reduction of emissions and energy consumption, with energy management, organizations can get the help and knowledge how to keep the budget of energy consumption as low as possible, how to meet all the critical objectives and also important, reduce their operational costs on a long-term basis.
