Abstract The increasing worldwide energy consumption, especially in the industry range, forces the companies to search for the solutions, which – being written into sustainable development philosophy – would allow for reducing the level of the energy consumption of the realised processes and lowering the costs of their functioning. Those activities can be undertaken in the systemic way, very often based on the implementation of the energy management system, they can also have the character of technical or technological modernisation. Fundament of the decision concerning the manner of the minimisation of energy consumption should always be the energy risk management covering: its identification, evaluation and acceptability assessment. The studies proposed the principles for defining the significant energy aspects by the full identification of all the present aspects and next the development of unified methodology of their assessment, allowing for appointing the key aspects. The starting point constitutes the energy risk ratio, which takes into consideration the following criteria: probability of the occurrence, significance of the occurrence, ability to monitor, incompatibility with legal requirements, and the interest and attention of the stakeholders. Flexibility of the applied method enables complex application in every organisation – independently of its size and sort of the realised processes – which wants to manage the risky energy aspects.

Energy Monitoring

Statistics show that energy is one of the highest operating costs in a manufacturing enterprise. So, improving energy efficiency can lead to a significant increase in profits and reduce the impact of the enterprise on the environment. To increase the performance of energy efficiency activities, it is necessary to implement an energy management system. One of the components of this system is energy monitoring, which, in turn, is based on the periodic collection and analysis of data to assess the state of the monitoring objects in terms of energy efficiency. In this paper, the role and place of energy monitoring in the energy management system of an industrial enterprise are noted. The paper proposes the concept of creating energy monitoring system in industrial companies, which is based on the combination of a monitoring system based on specific energy consumption, and usage of group energy characteristics of production facilities. Implementing such energy monitoring systems will allow to conduct operational control of energy efficiency of production facilities by creating individual systems for monitoring energy efficiency, as well as successfully carry out such monitoring at the enterprise and its subdivisions over longer periods of time using specific energy consumption indicators. It also provides general guidelines for conducting energy monitoring. These guidelines were formed based on the results of studying various methods and scientific publications in the field of energy monitoring, as well as on the basis of practical experience in the development and implementation of energy management systems. Particular attention is paid to the issues of processing and analysis of information about the objects of energy monitoring of industrial enterprises. The practical application of the concept of creating energy monitoring systems envisages gradual improvement of the existing monitoring system based on the specific energy consumption, which will be further completely replaced with individual energy efficiency monitoring systems.

An electric boat system as a pilot study for the electric ferry was designed and field-tested in Samal Island, Philippines, to verify sustainability for inter-island transport. This pilot study uses 4.5m monohull with a displacement weight of 343kg. During the experiment, two cases were compared: in the first case the boat was powered solely with batteries and in the other case with the aid of photovoltaic (PV) modules. For the first case, 24V electric propulsion was driven by two 12V, 100Ah batteries, which resulted to a navigational range of around 18, 16 and 15 trips with energy consumption of 111.64Wh, 117.19Wh and 123.92Wh respectively. In the second case, the photovoltaic modules were attached on the boat to supplement the PV used while on sail. Results in the second case showed that PV module supplemented energy was about to 13.4%, 26.8% and 38.7% using three different speeds like 3.18, 3.32 and 3.84knots and the navigational range extended to 4km, 1km, and 14.4km respectively. Therefore, the electric boat with the aid of PV module answers the problem in the energy management system that deals with the sustainability of the system in the inter-island transport in Philippines.

Nowadays to implement the energy management system it is important to fulfill not only the legal requirements but also to follow the set of recommendations prepared by international and national management standards. The purpose of this article is to prepare the concept and methodology for the optimization and improvement of the energy management system (EMS) for Universities with implementation of legal requirements and recommendations from international and national management standards with the help of digital technologies. During the research the systematic analysis, complex approach, logical sampling and analogy were used. It is shown that this process should be done with the help of the process-based approach, in accordance with ISO 9001, and energy management ISO 50001. The authors developed the structure of the basic standard of energy management: "Guidelines for the energy management system". It is proved that the involvement of the technical senior students in the project of EMS improvement allows to expand their competencies for new technics and technologies. Cloud service Bitrix24 was chosen for IT-support of the project. During the study, a list of characteristics was used as a basis for creating a query to the technology department of the university. DBMS Microsoft Access was chosen for its creation. In addition, the possible results of initiating a single database containing all the information needed for accounting and control of energy supply were listed. Moreover, the possibility of automated energy management system implementation and its results were considered. The required actions described in this research can be implemented in any University, that will extend energy management to any University worldwide.

Buildings will generate considerable resource and energy consumption, environmental impact, and costs throughout their entire life cycle. Life cycle assessment and life cycle cost methods have become widely used building sustainability evaluation methods internationally due to their long-term comprehensive evaluation perspectives and scientific quantitative calculation methods. In response to energy consumption management issues in green buildings, a questionnaire survey was conducted to investigate the concepts of sustainable development, green environmental protection, and energy consumption management of construction enterprise personnel. Through the survey, it can be seen that corporate executives generally have a sense of sustainable development and pay more attention to sustainable competition and the green development of enterprises. Approximately 90% of executives understand energy consumption models. Only 10% of employees do not understand, but they are acquired by the company’s frontline employees. The result of the feedback is just the opposite. Frontline workers pay little attention to the long-term development of the company. Only about 5% of employees are proficient in the energy management system, but the proportion of completely unknown is as high as 20%, indicating that the overall energy management awareness of Chinese enterprises still needs to be strengthened. Secondly, through design experiments, the energy-saving management effect of the energy consumption model was observed and analyzed. From the power saving and load test, we found that the monitoring of the energy consumption model is helpful for companies to choose more energy-efficient building circuit designs, achieving an average annual energy-saving effect of about 8%, so as to achieve the purpose of energy saving.

At present, there is a serious energy crisis around the globe which impacts greatly on the power grid. A smart and user friendly energy management system can control the energy consumption. In this paper, load power and energy management system is developed and simulated using Proteus Visual Design software.  The load analysis and measurement techniques are developed for single phase and three phase loads and implemented using Arduino Mega 2560 board.  User friendly controls are developed using the visual design feature of the software to control the energy consumption. The load power management system is simulated by measuring the power consumed by various residential loads such as lights, fans, air-conditioners, heaters. The industrial loads are simulated by squirrel cage induction motor. The load analysis summary is displayed on the Arduino 2.8 inch TFT display shield in a table format. The simulaion model is created for future hardware implementation and is tested under various practical input conditions. The Proteus Visual Design software is chosen in this resesarch due to its advantages such as professional PCB layout package, availability of nearly 800 microcontrollers in the library package etc.The developed model successfully measured the energy consumption of several loads and assist the user in controlling the energy usage through automation control techniques. The accuracy of the results shows that the technique and the model developed in this research can be used by engineers, students and hobbyists who are working with energy monitoring systems and smart home applications directly. This is an ongoing project where in the next stage, the hardware design of the simulation model will be implemented and tested in real time application.
