Experimental implementation of an IoT platform for automatic actuation in a building

L'Internet de les coses (IoT), i específicament el seu ús per a Smart Buildings, ha augmentat en popularitat en els darrers anys, gràcies a les millores en les tecnologies de comunicacions i en hardware que fa que sigui més fàcil que mai poder interconnectar dispositius. Un dels principals punts d'interès, particularment dels Smart Buildings, és la capacitat de millorar l'eficiència energètica i reduir el malbaratament, ajustant automàticament els recursos de l'edifici i proporcionar als usuaris més comoditat. Tenint en compte aquest concepte i intentant millorar la proactivitat dels Smart Buildings per gestionar de manera més eficient els recursos, la tesi "Design and simulation of an interoperable IoT platform for automatic actuation in buildings" proposa una solució, i la prova en un escenari virtual, modelant i simulant aquesta implementació. Seguint aquesta idea, en aquest projecte vam portar aspectes d'aquesta solució teòrica a un entorn real. Vam implementat una Wireless Sensor Network (WSN) a l'edifici, amb sensors i gateways, per tal de controlar i documentar els resultats d'una implementació real i la seva viabilitat. Les nostres conclusions criden l'atenció sobre les diferències entre els resultats obtinguts dels sensors simulats i els de sensors reals, així com els obstacles que s'han trobat durant l'experiment, oferint solucions per a dissenys futurs.The Internet of Things (IoT), and specifically its use for Smart Buildings, has been on the rise in the last few years thanks to improvements in wireless communications and hardware that make it easier than ever to interconnect devices. One of the main points of interest of Smart Buildings, in particular, is the ability to improve energy efficiency and reduce waste, automatically adjusting the building's resources and providing users with higher comfort. With this concept in mind, and trying to improve the proactiveness of Smart Buildings to more efficiently manage resources, the thesis "Design and simulation of an interoperable IoT platform for automatic actuation in buildings" proposes a solution and tests it in a virtual scenario, modeling the sensor values and simulating this implementation. Furthering this idea, in this project we brought aspects of this theoretical solution to a real environment. We implemented a Wireless Sensor Network (WSN) through the building, with real sensors and gateways, in order to monitor and document the results of a real implementation and its viability. Our conclusions draw attention to the differences between the simulated and real sensor implementations, as well as the obstacles that have been found during the experiment, offering solutions for future designs

Strategic energy management plan and MS ISO 50001:2011 compliance / Mohd Tarmizi Mat Asim...[et al.]

Strategic energy management plan is a long-term approach provided for achieving the goals set, determining the level of energy efficiency, detecting, controlling, monitoring and reporting on the performance of energy consumption. Successful strategic energy management plan builds long-term relationships with energy users and can improve the persistence of energy savings. It will also benefit the organization, the country and the world directly and indirectly. However, without the support, these benefits may not be achieved and the implementation of strategic energy management plan will not be successful. The objective of the study is to improve energy performance at TH Headquarters building and to reduce electricity energy consumption. The study started with preliminaries study, data collection, data analysis and strategic energy management plan development process. All data and information were sourced from data collection activity that has been processed and analyzed based on the needs such as occupant behavior, trend of energy used and energy performance. Furthermore, wastage factors, target saving baseline, energy performance indicator, and strategic energy management plan were identified and developed. The proposed methods refer to MS ISO 50001:2011 as a guideline

LED Roadway Luminaires Evaluation - Final Report

This research explores whether LEDroadway luminaire technologies are a viable future solution to providing roadway lighting. Roadway lighting enhances highway safety and traffic flow during limited lighting conditions. The purpose of this evaluation study is to determine the feasibility of transitioning from standard high pressure sodium (HPS) roadway luminaire to LED roadway luminaire on the MoDOT maintained highway system. This study includes performance evaluations, a feasibility analysis and a potential transition replacement program

An Internet of things model for field service automation

Due to the competitive nature of the global economy, organisations are continuously seeking ways of cutting costs and increasing efficiency to gain a competitive advantage. Field service organisations that offer after sales support seek to gain a competitive advantage through downtime minimisation. Downtime is the time between service requests made by a customer or triggered by equipment failure and the completion of the service to rectify the problem by the field service team. Researchers have identified downtime as one of the key performance indicators for field service organisations. The lack of real-time access to information and inaccuracy of information are factors which contribute to the poor management of downtime. Various technology advancements have been adopted to address some of the challenges faced by field service organisations through automation. The emergence of an Internet of Things (IoT), has brought new enhancement possibilities to various industries, for instance, the manufacturing industry. The main research question that this study aims to address is “How can an Internet of Things be used to optimise field service automation?” The main research objective was to develop and evaluate a model for the optimisation of field services using an IoT’s features and technologies. The model aims at addressing challenges associated with the inaccuracy or/and lack of real-time access to information during downtime. The model developed is the theoretical artefact of the research methodology used in this study which is the Design Science Research Methodology (DSRM). The DSRM activities were adopted to fulfil the research objectives of this research. A literature review in the field services domain was conducted to establish the problems faced by field service organisations. Several interviews were held to verify the problems of FSM identified in literature and some potential solutions. During the design and development activity of the DSRM methodology, an IoT model for FSA was designed. The model consists of:The Four Layered Architecture; The Three Phase Data Flow Process; and Definition and descriptions of IoT-based elements and functions. The model was then used to drive the design, development, and evaluation of “proof of concept” prototype, the KapCha prototype. KapCha enables the optimisation of FSA using IoT techniques and features. The implementation of a sub-component of the KapCha system, in fulfilment of the research. The implementation of KapCha was applied to the context of a smart lighting environment in the case study. A two-phase evaluation was conducted to review both the theoretical model and the KapCha prototype. The model and KapCha prototype were evaluated using the Technical and Risk efficacy evaluation strategy from the Framework for Evaluation of Design Science (FEDS). The Technical Risk and Efficacy strategy made use of formative, artificial-summative and summative-naturalistic methods of evaluation. An artificial-summative evaluation was used to evaluate the design of the model. Iterative formative evaluations were conducted during the development of the KapCha. KapCha was then placed in a real-environment conditions and a summative-naturalistic evaluation was conducted. The summative-naturalistic evaluation was used to determine the performance of KapCha under real-world conditions to evaluate the extent it addresses FSA problems identified such as real-time communication and automated fault detection
