Повний текст джерелаA dia d’avui l’energia és un bé completament necessari arreu del món. Degut als avantatges que presenta en el transport i a les necessitats de les llars i la indústria, l’energia és transformada en energia elèctrica. Tenint en compte la total expansió i domini de l’electricitat, iniciatives com Horitzó 2020, tenen per objectiu un futur més sostenible: reduint les emissions de carboni i el consum i incrementant l’ús de renovables. Partint dels defectes de la xarxa elèctrica clàssica, com són gran distància al punt de consum, poca flexibilitat, baixa sostenibilitat, baixa qualitat de l’energia, dificultats per a emmagatzemar energia, etc. apareixen les Smart Grid (SG), una evolució natural de la xarxa clàssica. Un dels principals elements que permetrà a les SG millorar les xarxes clàssiques és l’Energy Management System (EMS). Així doncs, per a que l’EMS pugui dur a terme la gestió dels diversos elements, una de les necessitats bàsiques dels EMS serà un sistema de predicció, o sigui, saber per endavant quin consum hi haurà en un entorn determinat. A més, les empreses subministradores d’electricitat també requeriran de prediccions per a gestionar la generació, el manteniment i fins i tot les inversions a llarg termini. Així doncs ens calen sistemes de predicció del consum elèctric que, partint de les dades disponibles, ens subministrin el consum que hi haurà d’aquí a unes hores, uns dies o uns mesos, de la manera més aproximada possible. És dins d’aquest camp on s’ubica la recerca que presentem. Degut a la proliferació de xarxes de sensors i computadors més potents, s’han pogut desenvolupar sistemes de predicció més precisos. A tall de resum, en el primer treball, i tenint en compte que s’havia de conèixer en profunditat l’estat de la qüestió en relació a la predicció del consum elèctric, es va fer una anàlisi completa de l’estat de l’art. Un cop fet això, i partint del coneixement adquirit, en el segon treball es va dur a terme la instal•lació de les xarxes de sensors, la recollida de dades de consum i el modelatge amb models lineals d’auto-regressió (AR). En el tercer treball, un cop fets els models es va anar un pas més enllà recollint dades d’ocupació, de meteorologia i ambient interior, provant diferents models paradigmàtics com Multiple Linear Regression (MLR), Artificial Neural Network (ANN) i Support Vector Regression (SVR) i establint quines dades exògenes milloren la predicció dels models. Arribat a aquest punt, i havent corroborat que l’ús de dades d’ocupació millora la predicció, es van generar tècniques per tal de disposar de les dades d’ocupació per endavant, o sigui a hores vista. D’aquesta manera es van dissenyar diferents atributs d’ocupació artificials, permetent-nos fer prediccions horàries de consum a llarg termini. Aquests conceptes s’expliquen en profunditat al quart treball.

Повний текст джерелаTiivistelmä Rakennus- ja kiinteistösektori on suurin fossiilisilla polttoaineilla tuotetun energian käyttäjä. Noin 40 prosenttia kaikesta energiankulutuksesta liittyy rakennuksiin, rakentamiseen, rakennusmateriaaleihin ja rakennuksien ylläpitoon. Ilmastonmuutoksen ehkäisyssä rakennusten energiankäytön vähentämisellä on suuri merkitys ja rakennuksissa energiansäästöpotentiaali on suurin. Tämän seurauksena yhä tiiviimpi ja energiatehokkaampi rakentaminen asettaa haasteita hyvän sisäilman laadun turvaamiselle. Näistä seikoista johtuen sisäilman laadun tutkiminen ja jatkuvatoiminen mittaaminen on tärkeää. Väitöskirjan päätavoitteena on kuvata kehitetty energiankulutuksen ja sisäilman laadun monitorointijärjestelmä. Järjestelmän tuottamaa mittaustietoa on jalostettu eri loppukäyttäjiä palvelevaan muotoon. Tiedonjalostusprosessi koostuu tiedon keräämisestä, esikäsittelystä, tiedonlouhinnasta, visualisoinnista, tulosten tulkitsemisesta ja oleellisen tiedon välittämisestä loppukäyttäjille. Aineiston analysointiin on käytetty tiedonlouhintamenetelmiä, kuten esimerkiksi klusterointia ja ennustavaa mallintamista. Väitöskirjan toisena tavoitteena on tuoda esille jatkuvatoimiseen mittaamiseen liittyviä haasteita sekä rohkaista yrityksiä ja organisaatioita käyttämään tietovarantoja monipuolisemmin ja tehokkaammin. Väitöskirja pohjautuu viiteen julkaisuun, joissa kuvataan kehitetty monitorointijärjestelmä, osoitetaan tiedonjalostusprosessin toimivuus erilaisissa tapauksissa ja esitetään esimerkkejä kuhunkin prosessivaiheeseen soveltuvista laskennallisista menetelmistä. Julkaisuissa on kuvattu energiankulutuksen ja sisäilman laadun informaatiopalvelu sekä sisäilman laatuun liittyviä data-analyysejä omakoti- ja kerrostaloissa sekä koulurakennuksissa. Innovatiivinen digitaalisen tiedon hyödyntäminen on avainasemassa kehitettäessä uusia informaatiopalveluita. Kiinteistöalalle on kehitetty lukuisia informaatioon pohjautuvia palveluita, mutta ala tarjoaa edelleen hyviä liiketoimintamahdollisuuksia kyvykkäille ja kehittyneille yrityksille sekä organisaatioille

Повний текст джерелаModel Predictive Control (MPC) is an advanced control technique which has played an important role in the management of many processes in the industry sector. Nowadays, in the perspective of an efficient building energy management, the exploitation of this strategy is proving to be a promising solution for minimising overall energy consumptions and costs. However, investigations on the feasibility of the technique in real existing buildings are at an initial stage. Hence, the main outcome of this dissertation is the design and development of a prototype hardware and software set up for on-field testing of a model-based predictive control system, integrating a virtual predictive model of the portion of the building under investigation, the controller and the interface to the monitoring and regulation devices used. Moreover, this research is addressed to investigate the technical feasibility of the development and deployment of a typical MPC system, which includes a monitoring sub-system, a data acquisition set up and a system identification method to obtain the model for the controller by means of a grey-box modelling approach. The modelling phase and the empirical approach developed are presented in the first part of this research thesis, while the core part concerns: the development of the MPC prototype, within a virtual instrument of LabVIEW software and the description of the experimental test, which was carried out during heating season, ensuring normal building operation during the entire monitoring period. Finally, this dissertation presents the study developed in simulation environment to investigate the potential of the control logic for the evaluation of retrofitting scenarios. The focus is on the definition of the main MPC simulator components and on the results obtained by testing one of the intervention scenarios.

Повний текст джерелаSweden has a number of environmental objectives, of which one is reduced climate impact. To achieve this goal measures have to be taken in order to reduce building energy use in residential and services sectors, sectors that accounted for over one third of Sweden’s total energy use in 2014. Poor regulation of heating, ventilation, and air conditioning (HVAC) is a common reason for often unnecessary high energy use in residential buildings and non-residential premises. Building automation integrates the buildings technical systems, such as HVAC, into one centralized system for monitoring and controlling, which then can be used to optimize the regulation for these systems. The market is however poorly mapped and information is missing regarding functions and area of use for these control systems. This report begins with a description of basic theory that is relevant for understanding parts later on. An analysis has then been made for a number of different building automation systems to clarify their functions, area of use, and potentials in energy savings. The report also describes the procedure for a real installation on Kv Slottet 4 and how the energy use and indoor climate has been affected after the building automation system has been installed. Results regarding the Swedish market overview shows that building automation is established in apartment buildings and non-residential premises while building automation is still unused in smaller houses. Some of the most common functions that are implemented in control systems are time clock operation, forecast control and power limitation. The analysis has shown that building automation can lead to energy savings between 10 to 40 %. The size of the saved energy depends on a number of factors like type of building, geographical location and former regulation of HVAC. The building automation companies are using different methods to calculate the energy saving why it is a problem to fairly compare different control systems. The information on energy savings for different type of buildings and technical systems are in many cases hard to get hold of. Generally speaking, the companies that provide mandatory agreements for operating the control system have more detailed information regarding energy savings. Four different companies were covered in this report. More companies should be mapped in order to make a more profound analysis. After the installation of Ecopilot® on Kv Slottet 4, a heat reduction of up to 20.6 MWh for the chosen period of time was achieved. That corresponds to a relative energy saving of 53 %. The energy saving varies depending on what method is used for calculation. The buildings total energy savings for electricity was 6.5 MWh, which corresponds to a 20 % reduction. The calculated energy saving is not all due to the building automation system but there has been some reduction. Ecopilot® has lowered the energy use by more efficient regulation, co-operating heating and cooling, more efficient heat recovery, lowered ventilation flows, and lowered temperatures. No change in indoor climate has been noticed by the people that were interviewed. The control system should be evaluated for a longer period of time to ensure how much it affects the indoor climate and the energy use in the building.

Повний текст джерелаWhen a new building is constructed, or some changes are taking place in the already existing building, it is required according to PBL chapter 8 that the developer applies for planning permissions at the building committee in that municipality where the real estate is located. In the planning permission, the documents of the current building are examined.
The developer will appoint a quality manager that helps the developer to ensure that all necessary controls are done and that the requirements in these are met. The developer has the final responsibility to ensure that the building is built according to all requirements and rules. The building committee establishes a control plan that shows which controls have to be carried out and which certificates and documents have to be sent in during the time of the construction.
This study aims to finding out which documents that will be submitted at the construction of a new building, according to the laws found in PBL, if these documents are required and if they are examined of the municipalities before the building is approved.

Повний текст джерелаThe Internet of Things (IoT) is the network of physical objects embedded with sensors and connectivity. The ubiquitous nature of IoT nodes will allow the deployment of embedded sensors, actuators, cameras, mobile phones, and Radio Frequency Identification Devices (RFID) in buildings for monitoring the condition of the building and the well being of the occupants. The current project presents the design and implementation of a sensor network within the IoT framework, using infrared (IR) sensors to monitor the number of visitors in the building and their distribution across predetermined zones. Using IR sensor data the Demand-Controlled Ventilation (DCV) units on each floor are controlled based on zone occupancies. The occupancy data are displayed on a mobile phone or PC using a Wireless Fidelity (WiFi) module. The devices in the experimental implementation of this network include IR, temperature, and CO2 sensors, interfaced to a microcontroller. Experimental testing shows that the network performs flawlessly and reliably.

Повний текст джерелаRecent researches and analysis reports declare that high energy consumption of buildings is major problem in developed countries. As a result, they show concretely that building energy management systems (BEMS) and deployed wireless sensor network environments are important for energy efficiency of building operations. In the literature, existing smart building management systems focus on energy consumption of the building, hardware deployed inside/outside of the building and network communication issues. They adopt static configurations for wireless sensor devices and proposed models are fitted to a single application. In this study, we propose a sustainable declarative monitoring architecture that focus on the energy optimisation of interactions between application service oriented queries and wireless sensor devices. We consider the monitoring system as a set of applications that exploit sensor measures in real time such as HVAC automation and control systems, real time supervision, security. These applications can be configured dynamically by the users or by the supervisor. In our approach, we take a data point of view: applications are declaratively expressed as a set of continuous queries on the sensor data stream. To achieve our objective of energy aware optimization of the monitoring architecture, we formalize sensor device configuration and fit data acquisition and data transmission to actual applications requirements. We present a complete monitoring architecture and an algorithm that handles dynamic sensor configuration. We introduce a platform that covers physical and also simulated wireless sensor devices

Повний текст джерелаWith the increasing awareness about the problem of climate change and the high level of energy consumption, a need for energy efficiency has emerged especially for electric power consumptions in buildings. To spur energy savings, industrials have been looking for measurement methods to monitor power consumptions. Appliance load monitoring has thus become an active research field. Monitoring and understanding the electrical consumption of appliances can also be useful for predictive maintenance, power quality analyses, demand forecasting or occupancy detection. Thirty years ago, a method called Non Intrusive Load Monitoring (NILM) has been introduced. It consists of estimating individual appliance energy consumptions from the measurement of the total consumption of the building. Its main advantage over traditional sub-metering methods is to use a single electric power meter at the main breaker of the building and then use a disaggregation algorithm to separate the contributions of each appliance. The goal of this thesis is to address the algorithmic challenge offered by NILM. The NILM problem can be formulated as a source separation problem, where the sources are the individual electric consumptions and the mixed observation is simply the sum of individual consumptions. Its main difficulties are: (i) the standardization of the formulation, (ii) the ill-posedness of the problem, (iii) the lack of knowledge and (iv) the machine learning algorithm design. All our contributions follow from the principal objective that is to solve the NILM problem for huge systems such as commercial or industrial buildings using high frequency current and voltage measurements. However, houses and the specific equipment found inside these buildings are not excluded of the study. This thesis is split into two parts.In the first part, we tackle the lack of knowledge and datasets for NILM in commercial buildings. First of all, the NILM community has mostly focused on both residential NILM application and using low frequency data provided by power meter installed by utility providers. To tackle the lack of knowledge on higher frequency data and on other kind of buildings such as commercial or industrial installations, we propose a statistical analysis based on public and private datasets. Our study on the rank of current matrix conducted for individual devices will serve as the base of a new device taxonomy and to prior assumptions on the rest of this thesis. Secondly, we address the lack of datasets especially for commercial buildings by developping an algorithm for generating synthetic current data based on a modelization of the current flowing through an electrical device. To encourage research on commercial buildings we release a synthesized dataset called SHED that can be used to evaluate NILM algorithms.In the second part, we deal with the NILM software challenges by exploring unsupervised source separation techniques. To overcome the unaddressed difficulties of processing high frequency current signals that are measured in large buildings, we propose a novel technique called Independent-Variation Matrix Factorization (IVMF), which expresses an observation matrix as the product of two matrices: the "signature" and the "activation". Motivated by the nature of the current signals, it uses a regularization term on the temporal variations of the activation matrix and a positivity constraint, and the columns of the signature matrix are constrained to lie in a specific set. To solve the resulting optimization problem, we rely on an alternating minimization strategy involving dual optimization and quasi-Newton algorithms. IVMF is the first proposed algorithm especially designed for high frequency NILM in huge buildings. We finally show that IVMF outperforms competing methods (Independent Component Analysis, Semi Non-negative Matrix Factorization) on NILM datasets

Повний текст джерелаIl lavoro sviluppato nell’ambito del dottorato di ricerca ha l’obiettivo di progettare, sviluppare, realizzare e verificare un sistema innovativo di sensori, e relativi algoritmi di elaborazione dei dati, che permetta di effettuare una rilevazione e una valutazione precise dei principali parametri ambientali ed energetici negli edifici. Il progetto è stato inserito all’interno di un progetto sovvenzionato dalla Regione Veneto nell’ambito del “Piano strategico per la ricerca scientifica, lo sviluppo tecnologico e l'innovazione 2008-2010” denominato SIMEA (Sistema Integrato/distribuito di Monitoraggio Energetico ed Ambientale). La rete di sensori ha lo scopo di produrre il profilo energetico/operativo dell’edificio per essere successivamente utilizzato: - ai fini della certificazione, per elaborare degli audit energetici in modo da migliorare le condizioni operative e di comfort; - per incentivare l’utilizzo ottimizzato delle risorse attraverso un controllo automatico intelligente; - per ricavare informazioni utili alle procedure di manutenzione. La teoria riguardante l’energetica degli edifici si basa sul sottile compromesso tra comfort e consumi e, infatti, tutte le normative sono volte a cercare di abbassare i consumi non compromettendo il comfort dell’ambiente interno dentro cui le persone vivono. A questo scopo, nel lavoro di tesi sono state considerate, tra le altre, la norma UNI EN 15251:2007 che definisce quali sono le componenti per assicurare il comfort indoor e la UNI EN 15603:2008 che specifica le tipologie di certificazione energetica; ed è proprio a quest’ultima che si riferisce il sistema di sensori sviluppato. La letteratura tecnica presenta numerosi studi volti a definire l’effettiva valutazione energetica di un edificio e se questa possa essere certificata con una metodologia basata su esecuzione di calcoli oppure su misure eseguite in loco. Si può concludere che i procedimenti non sono discriminanti ma complementari: i metodi di calcolo servono per una valutazione di tipo standard, implementata spesso da strumenti software, mentre i monitoraggi sono utilizzati per una valutazione reale dei consumi. Il sistema di sensori sviluppato cerca di soddisfare l’esigenza di utilizzare una metodologia basata sullo sfruttamento dei monitoraggi per la valutazione ad hoc del comportamento reale edificio-impianto ma supportato, per la valutazione del consumo energetico, da un software di calcolo validato a livello internazionale. La parte hardware del sistema di monitoraggio è formata da una serie di sensori per la misura delle varie grandezze termoigrometriche ed è diviso in due reti che differiscono per tipologia e obiettivi: la struttura a rete fissa, cablata, e la struttura a rete mobile, wireless. Lo sviluppo del progetto di dottorato ha permesso di utilizzare i monitoraggi eseguiti con il sistema di sensori installato, non solo per il calcolo dei consumi attuali ma per realizzare anche delle previsioni a breve termine, ovvero per il giorno successivo. In particolare le previsioni effettuate sono state eseguite in due modalità: - stima dei consumi con impianto di climatizzazione acceso e temperatura di setpoint impostata; - stima della temperatura in evoluzione libera con impianto spento. La parte conclusiva del lavoro è stata dedicata alla validazione delle previsioni eseguite nonché all’utilizzo della rete di sensori per altri scopi che potessero ampliare le potenzialità della sistema di monitoraggio sviluppato.

Повний текст джерелаThe general objective of this doctoral thesis project is to advance in the reliability and optimisation of Monitoring and Control Systems for HLC estimation and decoupling, in order to be able to define a minimum energy Monitoring Kit for residential or tertiary buildings in the future. These monitoring kits should be as unobtrusive as possible and should allow the minimum amount of data to be reliably monitored which, together with a correct analysis, should allow the real behaviour of the building envelope to be characterised.Thus after presenting the existing in-use HLC estimation and decoupling methods, the analysis of the State of the Art on monitoring and control systems for in-use building envelope energy characterisation is performed. Thanks to this review on monitoring and control systems analysis, it has been found that the overall uncertainty of indoor and outdoor temperature (when presented) is always considered to be the manufacturer’s accuracy in the existing literature. Using only the manufacturer accuracy as the overall uncertainty for these two important measurements required for the in-use HLC estimation, might lead to strongly underestimating their real uncertainty and this underestimation would be propagated to the estimated HLC values. To deeply analyse this topic, which could generate serious reliability issues for the estimated HLC values, a three dimensional monitoring system has been designed and deployed in an office building. To analyse the overall uncertainty of the indoor air temperature measurement, four thermal zones within the office building have been monitored with a three dimensional approach. To analyse the overall uncertainty of the outdoor air temperature measurement, a three dimensional monitoring approach has also been implemented around the building envelope.Furthermore, the results of this analysis have allowed the identification of the best location for the indoor and outdoor temperature sensors on the monitored building. Besides, the quantification of the discrepancies between the value of the sensor accuracy given by the manufacturer and the experimental value of the sensor accuracy plus the monitoring and control system has also been analysed. Here, the main contribution of this thesis can be found: the methodology developed to allow the quantification of the overall uncertainty of intensive variable measurements such as indoor air temperature and outdoor air temperature on in-use buildings. This methodology not only allows us to obtain the overall value of these measurements’ uncertainty containing all sources of uncertainty (called Measurement Uncertainty), but also allows us to decouple the Measurement Uncertainty into the uncertainty associated to the random and systematic errors. This decoupling separates the value of the variance associated with the overall uncertainty into the sum of two variances, one variance associated with the uncertainty related to the systematic errors (called in the study, Sensor Measurement Uncertainty) and another associated with the uncertainty related to the random errors (called in the study, Measurement’s Spatial Uncertainty).On the other hand, from the analysis of the Co-heating and Average method to estimate the HLC, an extremely detailed monitoring system has been designed and implemented in a residential building. The aim of this extremely detailed monitoring system is to be able to analyse what the minimum required set of sensors to estimate and decouple the in-use HLC values with a sufficient reliability. The selected sensors have the greatest possible accuracy that could be found for building sector applications. A detailed economic analysis is also included for this extremely detailed monitoring

This study is based on BACnet communication protocol that was published by ASHRAE. The relationships between the DDC (Direct Digital Control) applications and network communication protocol are discussed. The backgrounds and frameworks of BACnet, including its protocol on “Objects, Properties, and Services” are described. Visual Basic programming was used to design a communication program to communicate with DDC that conforms to BACnet protocol. Database management programming was then used to collect data from DDC systems. In addition, the integrated concept of BACnet is applied to the building energy monitoring. The energy consumption data were collected by digital power meters, and communicated via BACnet protocol so to integrate the building energy database. The building energy database includes the energy consumption of various equipments in the building, presented as Energy Use Intensity (EUI) and Demand Use Intensity (DUI). Analyzing monitoring data could help to understand the energy consumption trends, and in the analysis of energy saving potentials and control strategies for the building. An example, energy monitoring system was used to acquire the energy consumption of various equipments of a supermarket, and presented as EUI and DUI. In this example was used gateway to translate and communicate two different protocols — BACnet and Modbus.

Nonintrusive Load Monitoring (NILM) system is an innovative approach for monitoring electrical loads by analyzing the aggregated signatures such as voltage, current, active power, and reactive power from the main power supply. One of the products based on NILM is Building Energy Management System (BEMS), which helps user to understand the energy consumption of their building. However, there are two major problems if NILM is applied to BEMS directly. First, the extra power consumption of electric power transmission lines of building cannot be ignored and it influences the accuracy of the energy disaggregation. Second, NILM cannot distinguish two appliance instances if they have the same signatures. In this paper, we propose a location-based NILM technology to solve the problems mentioned above. Together with a smart training tool and a visualized app, we demonstrate that location-based NILM can considerably enhance the functionalities of BEMS. User can establish the topology model with smart training tool in minimal manual operations, and they can easily understand the improved disaggregation result with the visualized app.

Знайти повний текст джерелаResearch on net-zero energy buildings (NZEBs) has been largely centered around improving building energy performance, while little attention has been given to indoor air quality. A critically important class of indoor air pollutants are nanoaerosols – airborne particulate matter smaller than 100 nm in size. Nanoaerosols penetrate deep into the human respiratory system and are associated with deleterious toxicological and human health outcomes. An important step towards improving indoor air quality in NZEBs is understanding how occupants, their activities, and building systems affect the emissions and fate of nanoaerosols. New developments in smart energy monitoring systems and smart thermostats offer a unique opportunity to track occupant activity patterns and the operational status of residential HVAC systems. In this study, we conducted a one-month field campaign in an occupied residential NZEB, the Purdue ReNEWW House, to explore how energy use profiles and smart thermostat data can be used to characterize indoor nanoaerosol dynamics. A Scanning Mobility Particle Sizer and Optical Particle Sizer were used to measure indoor aerosol concentrations and size distributions from 10 to 10,000 nm. AC current sensors were used to monitor electricity consumption of kitchen appliances (cooktop, oven, toaster, microwave, kitchen hood), the air handling unit (AHU), and the energy recovery ventilator (ERV). Two Ecobee smart thermostats informed the fractional amount of supply airflow directed to the basement and main floor. The nanoaerosol concentrations and energy use profiles were integrated with an aerosol physics-based material balance model to quantify nanoaerosol source and loss processes. Cooking activities were found to dominate the emissions of indoor nanoaerosols, often elevating indoor nanoaerosol concentrations beyond 104 cm-3. The emission rates for different cooking appliances varied from 1011 h-1 to 1014 h-1. Loss rates were found to be significantly different between AHU/ERV off and on conditions, with median loss rates of 1.43 h-1 to 3.68 h-1, respectively. Probability density functions of the source and loss rates for different scenarios will be used in Monte Carlo simulations to predict indoor nanoaerosol concentrations in NZEBs using only energy consumption and smart thermostat data.

The thesis proposes a power saving strategy used in long time monitoring the temperature and humidity of the building. Because of the sleep mode and standby mode of electronic components can’t match the energy demand used for a long time monitor system in the embedded wireless transmission module. In addition, the measurement system transmits temperature and humidity information about building without high frequency. (In the thesis, the sampling period is thirty minutes.) In general, the sleep mode and standby mode of transmission module cause the main cell electrical consumption. How to reduce cell consumption in sleep mode is research priority. Because of the sensing circuit embedded in the building and the life of the building with several decades, power saving for cell is quite important of the self-made system in this study. The micro controller unit control analogy switches to shut down unused power of the electronic components could reduce the electrical consumption. Simultaneously, the sleep time for transmission module is adjustable, which achieve the purpose of increasing the useful life.

Повний текст джерелаNesta dissertação de mestrado, IoT * (AmbiSense), é apresentado um sistema IoT desenvolvido como uma solução para Gestão de Edifícios e Energia recorrendo a ferramentas de visualização para identificar heurísticas e criar poupanças automáticas. Os protótipos desenvolvidos comunicam utilizando LoRa, e são compostos por um conjunto de sensores ligados a um microcontrolador alimentado por bateria. Os sensores adquirem dados como temperatura, humidade, luminosidade, qualidade do ar e movimento. Para edifícios de pequena e média dimensão onde a gestão do sistema é possível, um dashboard fornece templates de visualização com dados em tempo real, permitindo extrair heurísticas, que introduzem poupanças através de um conjunto de ações predefinidas ou intervenção manual. O sistema LoBEMS (LoRa Building and Energy Management System), foi validado numa escola local durante um período de três anos. A avaliação do sistema resultou numa poupança de energia de 20% e uma melhoria significativa da qualidade do ambiente e conforto no interior da escola. Para edifícios de maior dimensão onde a gestão do sistema não é possível, criámos uma ferramenta de visualização 3D, que apresenta os dados e alertas do sistema, num modelo interativo do edifício. Este cenário foi validado no campus do ISCTE-IUL, onde foi necessária a interação da Comunidade para obter poupanças. Foi nos também solicitada uma validação do sistema no centro de dados da Universidade, onde os templates do sistema foram utilizados para detetar anomalias e sugerir alterações. A flexibilidade do sistema permite a sua implementação em qualquer edifício, sem exigir um grande investimento ou implementações complexas.

To hold down power consumption in preparation for upcoming period of high price of electricity, the thesis focuses on energy-saving constructions, from the viewpoint of a resource manager, the buildings must be constructed with the energy-saving concept from the beginning, and further become less power constructions. It is necessary to implement actively and effectively energy management for existing buildings. By modifying the type of electricity consumed, the electricity charge can be reduced and avoid power waste of electricity. This thesis presents the best scheme and management mode in electric saving for schools. Take example of National Tainan Art College, they had integrated successfully in consolidating methods of economical buildings and power-saving monitor to evaluate benefit of the power-saving program. They also make analysis comparison with other schools in energy consuming. The program also meets with the purpose of overload adjust at peak hours and balance electricity area structure of Taiwan Power Company. In this way to minimize the numbers of new electric plants and the inconvenience caused by electric restriction policy, so all users in Taiwan and Taiwan Power Company will be at a win-win base.

Повний текст джерелаHoje em dia a gestão dos recursos energéticos é considerada cada vez mais como um dos principais desafios da humanidade. Com o aumento sucessivo do custo da energia em Portugal, é essencial monitorizar e tomar as acções necessárias e importantes para a redução efectiva dos consumos energético. Esta tese de mestrado descreve o desenvolvimento e o teste de um sistema de monitorização de energia no edifício da Penteada da Universidade da Madeira, usando componentes genéricos de baixo custo e software aberto, para que a sua implementação e uso não represente custos adicionais. Neste trabalho é feita a monitorização dos consumos energéticos realizados no edifício da Penteada da Universidade da Madeira, através da instalação de vários sensores de corrente em pontos estratégicos, por onde passa a energia consumida na sua totalidade, de forma a recolher os dados de consumo energético do edifício e usálos para a construção de uma base de dados para referência futura, contribuindo para comparar os consumos em períodos diferentes e obter uma poupança em termos de custos e consumo de energia. Recorreu-se ao microcontrolador mbed para fazer o processamento e envio em tempo real dos dados obtidos através dos sensores de corrente, e ao microchip CAN (Controller Area Network) de forma a criar uma rede física para suportar o envio dos dados entre os vários microcontroladores mbed e o computador (com a base de dados).

Повний текст джерелаEm Portugal, o setor dos edifícios representa quase 30% dos consumos totais de energia, sendo que 12% diz respeito a edifícios de serviços. No ano de 2016, a maior parte dos certificados energéticos emitidos para este tipo de edifícios indicavam a classificação de C, (Bernardo, 2015; INE e DGEG, 2011; ADENE, 2016b). O elevado potencial de poupança energética neste tipo de edifícios incentiva a implementação de medidas de melhoria de eficiência energética, quer relacionadas com os elementos passivos do edifício quer com os seus sistemas ativos quer, ainda, com os sistemas e procedimentos de gestão de energia, O trabalho aqui apresentado tem como principal objetivo a identificação de oportunidades de melhoria de eficiência energética das agências de uma dada Instituição Bancária. O mesmo decorreu sob a forma de estágio inserido na equipa de gestão de energia da empresa Virtual Power Solutions, num projeto já em execução pela mesma. Dado envolver dezenas de agências com áreas destintas, os consumos de cada uma foram normalizados recorrendo ao indicador consumo específico de energia (kWh/m2).A análise dos consumos para os sistemas de AVAC (Aquecimento, Ventilação e Ar Condicionado) foi efetuado em separado para períodos de inverno e de verão, sendo posteriormente subdividido por zonas climáticas das respetivas agências. Foi possível concluir que o consumo médio de energia pelo AVAC é mais crítico no período de verão. Os consumos específicos de energia pela iluminação apresentam uma grande dispersão de valores, causada por algumas agências cujo o consumo específico de energia respeitante à iluminação é muito elevado. Visitaram-se algumas das agências com maior consumo específico de energia, para as quais são propostas medidas de melhoria. Estas apresentam payback simples com valores que variam entre 1 e 2 anos.Foi também realizado uma pequena análise a outros tipos de equipamentos existentes nas agências. Foi identificado uma grande percentagem de consumo de energia de equipamentos em standby, havendo também aí um grande potencial de poupança energética.De modo a gerar poupanças a curto prazo, foi levado a cabo um plano de deslastre de cargas dos sistemas de AVAC. Assim, foi possível realizar algumas análises, tais como a influência da zona climática nas poupanças de energia conseguidas.
In Portugal, the buildings sector accounts for almost 30% of total energy consumption, of which 12% refers to service buildings. In 2016, most of the energy certificates issued for this type of buildings indicated the classification of C. The high potential of energy saving in this type of buildings encourages the implementation of energy efficiency improvement measures, whether related to the passive elements of the building either with its active systems or with energy management systems and procedures.The main objective of the work is to identify opportunities for improving the energy efficiency of the agencies of a given Banking Institution. The same happened in the form of internship inserted in the energy manager team of Virtual Power Solutions. As it involved dozens of agencies with designated areas, the consumption of each was normalized using a specific energy consumption indicator (kWh/m2).An analysis of the HVAC systems (Heating, Ventilation and Air Conditioning) was carried out separately for winter and summer periods, being subdivided by climatic zones of the respective agencies. It was possible to conclude that the average of specific consumption by the HVAC is more critical in the summer period.The specific consumption of energy by illumination presents a great dispersion of values, caused by some agencies whose specific consumption of energy regarding the illumination is very high. We visited some of the agencies with the highest specific energy consumption, for which improvement measures are proposed. These have simple payback values ranging from 1 to 2 years.A small analysis was also done on other types of equipment in the agencies. A large percentage of the energy consumption of standby equipment has been identified. There is also a great potential for energy savings.In order to generate savings in the short term, a load shedding plan of the HVAC systems was carried out. Thus, it was possible to perform some analysis, such as the influence of the climatic zone on the energy savings achieved.
