    IoT is a term that symbolizes the relationship between objects or equipment using the internet. This study aims to develop an energy consumption monitoring system using the Internet of Things (IoT). The system development process in this study is an adaptation of the Waterfall model which contains five phases namely requirement, design, implementation, verification and maintenance phase. The findings of this study show that there are several problems that have been identified that are difficult to know the amount of energy used by a load, no facilities to monitor energy consumption remotely, data collected by kwj meters are not specific or detailed and methods of measuring electricity consumption are complicated and takes a long time. In conclusion, the energy consumption monitoring system using this IoT has successfully achieved the objectives set by the researchers. While the estimated cost for this system is also Rm200 which is an affordable price per user. With this system, researchers want to implement efficient energy usage while at the same time facilitating the use of consumers who want to do data analysis on energy usage. In addition, the researcher also hopes that future research can solve the problem and facilitate the user's business is doing something based on the suggestions and comments provided

    Get PDF
    This paper presents a smart energy consumption monitoring platform for machining processes with a unique electrical energy consumption indicator (EECI) for the evaluation and comparison of machining processes in terms of energy efficiency. The purpose of the developed smart monitoring platform with the integrated EECI and the Industry 4.0 digital technologies is to raise the level of efficiency of the machining process and thus to stimulate more sustainable and environmentally friendly machining. The energy consumption monitoring of a milling process is performed by connecting a machine tool with integrated sensors for measuring electrical power and cutting force to a cloud platform by using resources for signal acquiring and data acquisition. The platform includes applications for energy consumption monitoring and/or analysis. Results of four machining experiments are presented to demonstrate the effectiveness of the proposed energy consumption monitoring in machining and the applicability of the newly introduced EECI at the engineering and the operational level

    The European Commission has been developing efforts resulting in directives and programs to stimulate water saving. The lack of information about water usage in public bathing facilities is an obstacle to achieve an adequate management. This work proposes a monitoring system able to observe individual water consumption in public bathing facilities. Gathered information will be used to characterize user behaviour, or even to drive changes in their attitudes.info:eu-repo/semantics/publishedVersio

    Methodology for energy audits in the framework of the energy efficiency directive

    Get PDF
    The Energy Efficiency Directive 2012/27/EU (EED) was released in October 2012 and transposed in June 2014 by Member States. The Directive requires large companies to carry out an energy audit before December 2015, which has to be repeated every 4 years. A possibility for companies to be exempted from regular energy audits is to be or become certified by an approved energy management system (EnMS), most likely the international standard ISO 50001. In both cases it means that companies have to set plans and define actions to comply with European and national requirements that aim at improving their energy efficiency. Considering the differences across European countries regarding the awareness and involvement of the industrial sector in terms of energy management, a large number of companies still lack systematic and comprehensive systems to understand, monitor and improve their energy consumption in a cost-effective and sustainable way. This paper presents a methodology to carry out indicative energy audits in compliance with the European standard EN 16247-1 and including the ISO 50001 requirements of the energy planning phase (e.g. energy review, energy baseline and energy performance indicators). The proposed methodology follows a top down approach, starting from the energy bill and identifying major energy sources. It covers the evaluation of the actual system’s energy efficiency, identifies energy savings opportunities and presents an innovative approach for energy consumption monitoring via surrogate models of processes. It makes use of state-of-the-art techniques such as data reconciliation, heat integration via total site pinch analysis and statistical tools. Since natural gas and electricity usually take up the largest share of the total energy consumption in industry, the focus is put on these two energy carriers. One of the interesting aspects of the methodology concerns the data gathering and processing phases. Here the required data are targeted and classified in a systematic way in order to characterise the energy consumers and identify the areas of significant energy use presenting a potential for energy efficiency improvement. Once the energy review step is carried out, strategies for energy consumption monitoring should be developed. The methodology proposes an innovative approach to generate specific energy consumption models of industrial processes (surrogate models) that could be used to monitor units, online or offline, and detect deviations from expected behaviour

    This paper subsumes the implementation of automation in tracking the electrical consumption data of household systems over the network (WEB). This could sub-sequentially cut down the manual work involved in the process of collecting no: of units consumed from each house, thereby avoiding the manual costs and errors by building an automatic network access. The installation of this system is quite an easy task, which do not need much hardware work. The key elements that make this system are Current sensor and Voltage sensor interfaced to an Arduino board (A General Purpose Micro Controller board) with an Ethernet shield and a WIFI Router for transmission of data wirelessly to the server for storing consumption values into the database. Hosting web pages with the database connectivity will make the administrator generate electricity bill automatically that facilitates user’s to view and pay his electricity bill online
