For the assessment, we adopted and simplified a previously developed mathematical model of a parabolic trough solar receiver comprising an outer cover, annular space, abosrber, and heat transfer fluid, and discretized the governing equations using the finite difference method. Subsequently, we validated the model with the experimental data available in the literature and employed it to study the following: (1) the effects of annular pressure on the collector performance for the three HTFs and (2) collector performance subject to different concentration ratios (i.e., aperture area) and inlet HTF temperatures. Simulation results demonstrate the meager thermal performance of Syltherm 800 compared to Therminol VP-1 and Dowtherm Q that achieve similar performance. In addition, we show that there is an optimal aperture area and inlet fluid temperature for Syltherm 800 that yield maximum collector efficiency. Henceforth, we anticipate this work to provide a rough guideline on the selection of an appropriate HTF for future PTCs from the thermal standpoint.","PeriodicalId":142240,"journal":{"name":"2016 IEEE Conference on Technologies for Sustainability (SusTech)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133861529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Not only the trend toward clean energy sources triggered a process of rethinking in the minds of society but also pushed the politics to create incentives for companies in order to make them reduce their carbon footprint. Efficient use of resources has become a fundamental part of present-day economic, social and political decision making. Energy efficient production is no longer considered just under ecological aspect. It is considered as an important part of business strategy. Through high energy taxes, enormous energy costs and continuously increasing energy prices manufacturing companies are under permanent stress. However, there is for companies in the field of energy management enormous potential to financially improve and save costs consequently. Standards have provided a guide line for the companies to move towards green production. However lack of know-how and appropriate software tools and absence of concepts and methods for green production hinders company's especially small and medium size enterprises to take the step towards green production. Systematic and strategic energy management is the key to transform a company from lean to green production. Because of the complexity of the tasks related to environment and energy management, the Institute for Factory Automation and Production Systems (FAPS) developed methods and concepts to implement a strategic energy management. Furthermore, a software is developed that enables companies to follow the ISO 50001 guidelines and implement energy management methods necessary for a green production. This paper provides a brief road map showing the path to an energy efficient production environment. Starting from the list of the main energy consuming applications in German industries, which were identified through a study carried out in 2015. Brief description of the energy management methods and concepts and illustration of the role of strategic energy management in transforming companies from lean to green production and finally a brief illustration of the software for the implementation of energy management especially in manufacturing companies.","PeriodicalId":142240,"journal":{"name":"2016 IEEE Conference on Technologies for Sustainability (SusTech)","volume":"7 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132609262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The solar simulator is intended to be used by students for the Renewable Energy Laboratory as a controllable indoor test equipment under laboratory conditions for characterizing and testing solar panels. The use of Xenon, Halogen and LED bulbs allows the students to compare the spectrum differences between these light modules and how that affects the characteristics of the solar panel. A control system was attached to the light modules to control the light intensity of the modules. A measurement unit was also attached to the system for plotting the IV characteristics and determining the solar panel parameters (open circuit voltage V, short circuit current I, maximum power point I and V).","PeriodicalId":142240,"journal":{"name":"2016 IEEE Conference on Technologies for Sustainability (SusTech)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130021866","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, previous work on load prediction lacks to consider a wider set of possible data sources. In this paper we study different data scenarios to map the influence of the different data parameters. We also look at the temporal aspect of predicting by looking at the predicted seasons. By predicting with a MultiLayer Perceptron, which is a universal approximator, it is possible to focus solely on the influence of the parameters instead of the prediction algorithm itself. Finally, multiple prediction algorithms are compared. The influential factor analysis is based on data from an entire year from a office building in Denmark. The results show that weather data is the most crucial data parameter. A slight improvement from load data was however seen using only occupancy data. Next, the time of day that is being predicted greatly influence the prediction which is related to the weather pattern. By presenting these results we hope to improve the modeling of building loads and algorithms for Demand Response planning.","PeriodicalId":142240,"journal":{"name":"2016 IEEE Conference on Technologies for Sustainability (SusTech)","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125620526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Microgrids are a step to a more hybrid, less centralized power industry. A key objection from traditional electric utilities to distributed renewable energy is the variation injected to the power grid from variables sources such as the sun. A significant milestone would be to manage that variation from renewable sources before it reaches the grid. Furthermore, if a renewable-driven subsystem demands a fixed block of power from the grid, the potential impacts from interconnecting renewable energy are minimized. This paper presents work on such seamless grid interconnection, focusing on zero or low net energy community microgrids.","PeriodicalId":142240,"journal":{"name":"2016 IEEE Conference on Technologies for Sustainability (SusTech)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133061685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While WSN has the abilities of sensing, processing and communication over distances, its abilities are limited by the capacity of its battery. To use the full functionalities of WSN, either the battery needs to replace or recharge in a periodically manner. However both solutions are not convenient for livestock monitoring system. The only way to solve the issue effectively and efficiently is to recharge the battery wirelessly. Due to the harsh operating environment, the sensor node has to be waterproofed within a sealed enclosure which then brings up a mind-boggling challenge of how to charge a battery when it is concealed? Therefore, Wireless Power Transfer (WPT) solution seems to be a sole solution to solve the issue in WSN for livestock farming. In this work, we propose a WSN livestock health monitoring system using Near Field Communication (NFC) to monitoring key parameters like temperature to monitor the health of livestock. WPT will also be discussed as how it provides a means for electronic devices to obtain power wirelessly without any physical connectivity to the WSN which is attached to the herds for health monitoring purpose.","PeriodicalId":142240,"journal":{"name":"2016 IEEE Conference on Technologies for Sustainability (SusTech)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116483004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since the establishment of the Kyoto Protocol in 1997, several models have been proposed to limit the emission of Greenhouse Gases (GHGs) by trying to enforce abiding regulations to the participating countries. One of the successful implementations of such models is the Emission Trading System in the European Union, which economically incentivizes the carbon-heavy industries to cut their emissions on a gradual basis. In this paper, we have modeled the involving factors in such a carbon market through the system dynamics methodology, proposing a system of differential equations between the main factors such as the Emission Allowances supply, demand and their price. The coefficients are derived based on a Least Absolute Deviation (LAD) analysis on the historic available data. We analyze the effect of an implementable policy and show that by consistently increasing the coverage of the emissions from industries, the EU commission can reach to its predefined set values of the allowable volumes of emissions by 2050.","PeriodicalId":142240,"journal":{"name":"2016 IEEE Conference on Technologies for Sustainability (SusTech)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124621441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One challenge in enabling portable applications is metadata about building instrumentation. The problem is that there are multiple ways to annotate sensor and actuation points. This makes it difficult to create intuitive queries for retrieving data streams from points. Another problem is the amount of insufficient or missing metadata. We introduce Metafier, a tool for extracting metadata from comparing data streams. Metafier enables a semi-automatic labeling of metadata to building instrumentation. Metafier annotates points with metadata by comparing the data from a set of validated points with unvalidated points. Metafier has three different algorithms to compare points with based on their data. The three algorithms are Dynamic Time Warping (DTW), Empirical Mode Decomposition (EMD), and the differential coefficient. Two of the algorithms compare the slope of the data stream in the values. EMD finds similarities based on the frequency bands among the data stream. By using several algorithms the system is robust enough to handle data streams with only slightly similar patterns. We have evaluated Metafier with points and data from one building located in Denmark. We have evaluated Metafier with 903 points, and the overall accuracy, with only 3 known examples, was 94.71%. Furthermore we found that using DTW for mining points with the point type of room temperature achieved an accuracy as high as 98.13%.","PeriodicalId":142240,"journal":{"name":"2016 IEEE Conference on Technologies for Sustainability (SusTech)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126367753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
