Повний текст джерелаA substantial amount of the energy usage in developed countries is consumed by climate control of residential and commercial structures. Collecting information on the usage patterns of heating, ventilation and air conditioning (HVAC) systems can allow a consumer to better understand the cost and effectiveness of these systems, and allow landlords and others to monitor their use. This paper describes a system which can easily be retrofitted onto legacy HVAC systems to monitor their activity, and then transmit the information over a wireless radio network for archiving and analysis

Повний текст джерелаThe purpose of this research is to minimize the use of active systems in providing thermal comfort in single-family detached, middle to high income residential buildings in Bloemfontein. The typical case study house was selected according to the criteria as reviewed by Mathews et al., (1999). Measurements were taken for seven days (18 – 24 May 2009). The measurements were carried out in the winter period for Bloemfontein, South Africa. Ecolog TH1, humidity and temperature data logger was used in doing the measurements. These measurements included indoor temperatures and indoor relative humidity. Temperature swings of 8.43 ºC and thermal lag of 1 hour were observed. For the period of seven days (168 hours), the house was thermally comfortable for 84 hours. Thermal analysis for the base case house was done using Ecotect™ (building analysis software) and the simulated results were compared with the measured results. A mean bias error (MBE) of between 10.3% ≤≤11.5% was obtained on the initial calibration. The final calibration of the model yielded error between0.364% ≤≤0.365%. The final calibration model which presented a small error was adopted as the base case. Passive strategies were incorporated to the Ecotect™ model (final calibrated model) singly and in combination; then both thermal and space load simulations were obtained and compared to simulations from the original situation (base case) for assessing improvements in terms of thermal comfort and heating, ventilation and air conditioning (HVAC) energy consumption. Annual HVAC electricity savings of up to 55.2 % were obtained from incorporating passive strategies in combination. Incorporating passive strategies resulted in small improvements in thermal comfort.

Although energy efficiency has potential to be a significant energy resource in the United States, many energy efficiency projects continue to go unrealized. This is especially true in the residential sector, where efficiency programs, frequently administered by utilities, see very low participation rates. However, growing access to data and the growing prevalence of mapping technologies provide new avenues for introducing energy performance information in ways that could encourage increased energy efficiency implementation. Renters and homebuyers are increasingly using online interactive maps to inform their housing choices. If energy data is mapped or incorporated into an existing real estate map, energy efficiency could become a valued asset that influences housing decisions and encourages building upgrades by property owners. However, major obstacles remain in accessing the data necessary to create meaningful energy maps. Privacy is the most significant barrier to displaying building-level energy consumption and performance information. This thesis explores how an energy map could catalyze energy efficiency upgrades, specifically in the residential market. This research examines existing energy maps, existing energy assessment platforms and what data they use, and evaluates the state of energy data access in the United States. It seeks to answer what data is necessary to map building level energy performance, what policies are necessary to access that data, and how should energy information be displayed in a map for the most meaningful impact. This research suggests that State mandates may be necessary to access individual residential building energy data; that the Federal government should recommended a standardized platform, such as the Standard Energy Efficiency Data platform, to create a national standard for storing energy data and data taxonomy; and that an energy map will be most effective when displaying a relative energy performance score which could possibly be calculated from energy data and other publicly available building records.

Повний текст джерелаIn the thesis, causes of the energy efficiency gap, i.e. that seemingly attractive investments in energy efficiency are systematically passed over are explored, and policy instruments and business strategies that can be used to overcome this inefficiency are discussed. The economic literature of the efficiency gap focuses either on factors that are not included in the calculations of the gap, and that may explain why observed behaviour is actually efficient, or market failures that justifies policy intervention. In response to the economic literature, organizational and behavioural approaches have arisen, focusing on factors that preclude some of the assumptions made in economic theory.
A case study of four organizations has been carried out, investigating the decision processes, investment rules and motivation for energy efficiency measures. The main results are that all the organizations work systematically with energy observation and improving practices, while larger investments seem to be less prioritized. The building managers seem to cope with uncertainty by being conservative. Direct economic profitability is considered sufficient motivation for implementing energy-efficiency measures, while at the same time, the choice of investment objects is guided by strategic targets or general desirability. Capital-rationing occurs, but this competition among profitable projects is not considered a problem in the organizations. There is also some evidence of lack of incentives for energy conservation among occupants. A possible connection between emphasis on environmental results centrally in the organization and improvement in energy efficiency is established, and there are some indications that the start-up of an energy program depends on individuals.
The discussion of strategies to increase implementation of energy efficiency measures focuses on how to allow for technological change, and particularly diffusion of technologies. In this regard, looking for positive feed-back loops is important. A combination of market-based and behavioural instruments seems appropriate. Three specific strategies are explored: energy contracting, energy certificates and start-up help for arranging goals and routines for improvement.

Energy efficiency will help South Africa meet some of its socioeconomic goals whilst protecting the environment and using resources effectively. In light of the recent blackouts, South Africa has stepped up its energy efficiency initiatives in order to delay the need for new generation capacity, but human behavioural responses often tend to offset the beneficial effects of such initiatives. Such behavioural changes are called the rebound effects. Energy modelling using LEAP was carried out for the South African residential electricity sector. The results from the LEAP modelling suggest that reducing residential electricity demand by 10% in 2030 will require high penetration rates of efficient appliances and in order to mitigate the rebound effect, efficiency initiatives should be carried out in conjunction with awareness campaigns and price interventions.

Повний текст джерелаConsumption, in general, represents the process of using a type of resource where savings needs to be done. Energy consumption has become one the main issue of urbanization and energy crisis as the fossil depletion and global warming put under threat the planet energy utilization. In this thesis, an automatic control of energy was developed to reduce energy consumption in residential area and passive house buildings. A mathematical model founded on empirical measurements was developed to emphasize the behavior of a testing laboratory from Universitatea Politehnica din București - Université Politechnica de Bucarest - Roumanie. The experimental protocol was carried out following actions such as: building parameters database, collecting weather data, intake of auxiliary flows while considering the controlling factors. The control algorithm is controlling the system which can maintain a comfortable temperature within the building with minimum energy consumption. Measurements and data acquisition have been setup on two different levels: weather and buildings data. The data collection is gathered on a server which was implemented into the testing facility running a complex algorithm which can control energy consumption. The thesis reports several numerical methods for estimating the energy consumption that is further used with the control algorithm. An experimental showcase based on dynamic calculation methods for building energy performance assessments was made in Granada, Spain, information which was later used in this thesis. Estimation of model parameters (resistances and capacities) with prediction of heat flow was made using nodal method, based on physical elements, input data and weather information. Prediction of energy consumption using state-space modeling show improved results while IoT data collection was uploaded on a Raspberry Pi system. All these results were stable showing impressive progress in the prediction of energy consumption and their application in energy field

Повний текст джерелаThe paper presents a critique of passive and active thermal comfort strategies. Extensive review of literature on passive thermal comfort energy efficiency interventions and their benefits was under taken. The paper explains the correlation between climatic comfort and energy efficiency. The applicability of the energy management process in ensuring energy efficiency is presented. Passive thermal comfort energy efficiency interventions have been seen to provide thermal comfort as well as energy efficiency. Their major shortcoming is their disability to work in all kinds of weather, heating in the winter and cooling in the summer. There is need to optimize passive thermal comfort energy efficiency interventions so that they provide heating in the winter and cooling in the summer.

Повний текст джерелаDue to the energy shortage situation of the world and building sector occupies the most significant particle of total energy consumption, promoting the energy efficiency in the buildings has become one of the most urgent goals for energy develop the profession. The purpose of this project is to look for the most reasonable method, which is efficient and can be carried out in a short term with a lower investment, to reach the goal of energy efficiency in residential buildings in China. Considering that China is a vast territory country, the whole mainland is separated into five parts according to the various climate types in order to research accurately. A base building has been modeled in five climate zones at the same time. The software Designbuilder is used to simulate the base scenario, the building envelope improved scenario and the HVAC system improved scenario. The final suggestion is given according to the comparison of these three scenarios.Besides, some other technologies have been given in the thesis. These methods would take a longer time period or more investment, but still are good choices for residential buildings energy efficiency. They should be promoted in the future by the government support.

Повний текст джерелаENGLISH ABSTRACT: Energy efficiency, as the effective use of energy, is recognized as one of the simplest ways to improve the sustainable use of resources and by implication involves the end-user. The 2008 power crisis which South Africa experienced, highlighted supply exigencies and prompted a subsequent emphasis on affordable, rapidly scalable solutions, notably energy efficiency. As the establishment of new supply capacity is both costly and time-consuming, the logical alternative has been to focus intervention on the demand side. Residential electrical end-use has been identified as an area where the potential for change exists and strategies to address residential demand have gained momentum. The vulnerability of energy systems affects energy security on technical, economic and social levels. South African consumers are confronted with rising living costs and a substantial increase in electricity prices according to the Integrated Resource Plan for Electricity (2010-2030). Integral to addressing end-use is the ensuing behaviour of the end-user. End-use analysis aims to grasp and model customer usage by considering the electric demand per customer type, end-use category, appliance type and time of use. This project has focussed on the development of an interactive web application as a tool for residential end-users to improve energy efficiency through modified consumption behaviour and the adoption of energy efficient habits. The objectives have been aimed at educating an end-user through exposure to energy efficient guidelines and consumption analysis. Based on a Time Of Use-framework, a consumer’s understanding of appliance usage profiles can help realize the cost benefits associated with appliance scheduling. In order to achieve the desired functionality and with extendibility and ease of maintenance in mind, the application relies on the provision of dynamic content by means of a relational database structured around end-use categories and appliance types. In an effort to convey only relevant information in the simplest way, current web technology was evaluated. The resulting design has favoured an interactive, minimalistic, graphic presentation of content in the form of a Rich Internet Application. The development process has been divided into two phases. The residential energy consumption context has been substantiated with a case study of which the main objective and outcome has been to devise a methodology to generate usage profiles for household appliances. Phase one of the development process has been completed, as well as the case study. The conceptualization and framework for phase two has been established and the recommendation is to incorporate the methodology and usage profile results from the case study for implementation of the second phase. The effectiveness of the tool can only be evaluated once phase two of the application is complete. A beta release version of the final product can then be made available to a focus group for feedback.
AFRIKAANSE OPSOMMING: Energie effektiwiteit, gesien as die effektiewe aanwending van energie, word herken as een van die eenvoudigste maniere om die volhoubare gebruik van hulpbronne te bevorder en betrek by implikasie die verbruiker. Die 2008 kragvoorsieningskrisis wat Suid-Afrika beleef het, het dringende tekorte aan die lig gebring en ’n gevolglike klemverskuiwing na bekostigbare, maklik aanpasbare oplossings, vernaamlik energie effektiwiteit. Aangesien die daarstelling van nuwe voorsieningskapasiteit beide duur is en baie tyd in beslag neem, was die voor die hand liggende alternatief om te fokus op vraag-kant toetrede. Huishoudelike elektriese verbruik is geïdentifiseer as ’n area waar die potensiaal vir verandering bestaan en strategieë om residensiële aanvraag aan te spreek het momentum gekry. Die kwesbaarheid van energiestelsels affekteer energie sekuriteit op tegniese, ekonomiese en sosiale vlakke. Suid-Afrikaanse verbruikers word gekonfronteer met stygende lewenskoste en ’n aansienlike toename in elektrisiteitspryse volgens die Geïntegreerde Hulpbron-Plan vir Elektrisiteit (2010-2030). Eie aan die aanspreek van verbruik is die voortvloeiende gedrag van die verbruiker. Verbruiksanalise poog om verbruik te begryp en te modelleer deur die elektriese aanvraag na gelang van verbruikerstipe, verbruikskategorie, toesteltipe en tyd van verbruik in aanmerking te neem. Hierdie projek het gefokus op die ontwikkeling van ’n interaktiewe web-toepassing as ’n instrument vir residensiële verbruikers om energie effektiwiteit te verbeter deur gewysigde verbruiksgedrag en die ingebruikneming van energie effektiewe gewoontes. Die doelwitte is gerig op die opvoeding van ’n verbruiker deur blootstelling aan riglyne vir energie effektiewe verbruik en verbruiksanalise. Gebaseer op ’n Tyd-Van-Verbruik-raamwerk, kan ’n verbruiker se begrip van toestelle se verbruiksprofiele ’n bydrae lewer om die koste-voordele geassosieer met toestel-skedulering te realiseer. Om sodoende die verlangde funksionaliteit te bewerkstellig en met verlengbaarheid en gemak van onderhoud voor oë, steun die toepassing op die verskaffing van dinamiese inhoud deur middel van ’n relasionele databasis wat gestruktureer is rondom verbruikskategorieë en toesteltipes. In ’n poging om slegs toepaslike informasie in die eenvoudigste vorm weer te gee, is teenswoordige web tegnologie geevalueer. Die vooruitspruitende ontwerp is ’n interaktiewe, minimalistiese, grafiese aanbieding van die inhoud in die vorm van ’n sogenaamde "Rich Internet Application". Die ontwikkelingsproses is ingedeel in twee fases. Die huishoudelike energieverbruikskonteks is bevestig deur middel van ’n gevallestudie waarvan die vernaamste doelwit en uitkoms was om ’n metodologie daar te stel om verbruiksprofiele van huishoudelike toestelle te genereer. Fase een van die ontwikkelingsproses is voltooi asook die gevallestudie. Die konsepsuele onwikkeling en raamwerk vir fase twee is reeds gevestig en die aanbeveling is om die metodologie en verbruiksprofielresultate van die gevallestudie te inkorporeer vir implementering van die tweede fase. Die effektiwiteit van die toepassing kan eers geevalueer word sodra fase twee afgehandel is. ’n Beta-weergawe vrystelling van die finale produk kan dan beskikbaar gestel word aan ’n fokusgroep vir terugvoer.

Повний текст джерелаENGLISH ABSTRACT: Energy efficiency and the move to renewable energy resources are of vital importance in growing profitable and sustainable economies. In recent years, greater emphasis has been placed on institutions, companies and individuals to reduce their electrical energy demand through energy management. In an attempt to reduce the demand, the electrical power utility in South Africa, Eskom, has introduced Demand Side Management programs and substantial increases in electricity tariffs. In addition to these, tax incentives have been offered to help off-set the capital costs associated with the investments made in replacing old electrical equipment with new electrically efficient equipment. Thus the need for accurate Measurement and Verification of electrical energy demand reduction, to substantiate fiscal claims, has become imperative. The main purpose of Measurement and Verification is to investigate the actual monetary performance of an energy savings project. Energy savings assessments, based on purely deterministic baseline demand, do not adequately represent the statistical nature of the savings impacts of many practical load systems, as disclosed in a reporting period. This thesis presents the development of a generic probabilistic methodology to determine the demand profiles of preand post-Energy Conservation Measures (ECMs) for practical load systems. The difference between the simulated demand of the pre- and post-ECMs for a particular set of variables represent the electrical demand impact. The electrical demand of the pre- and post-ECMs is defined in terms of Probability Density Functions, and derived using a multivariate kernel density estimation algorithm. The approach is tested using a simulation model of a waterheating geyser implemented in MATLAB. Three different ECMs are simulated using the geyser model and demand density estimation. The results of the demand impacts of the ECMs are presented and evaluated. With regards to possible future research this methodology could be applied to the evaluation of the demand impacts of heat pump technologies and solar water heaters.
AFRIKAANSE OPSOMMING: en die skuif na hernubare energiebronne is van deurslaggewende belang vir die ontwikkeling van winsgewende en volhoubare ekonomieë. Onlangs is meer klem geplaas op instansies, maatskappye en individue om hul aanvraag na energie te verminder met behulp van energiebestuur. In ‘n poging om die aanvraag te verlaag, het Eskom, Suid-Afrika se elektrisiteitsverskaffer, aansienlike elektrisiteitstariefverhogings ingelyf en Aanvraagbestuursprogramme van stapel gestuur. Bykomend hiertoe is belastingaansporings ook aangebied, waarteen kapitale kostes, geassosieer met die vervanging van ou elektriese toerusting met nuwe elektries doeltreffende toerusting, afgeset kan word. Derhalwe het die behoefte aan akkurate Meting en Verifikasie van elektriese energie aanvraagvermindering, om finansiële eise te staaf, noodsaaklik geword. Die hoofdoel van Meting en Verifikasie is om die werklike finansiële prestasie van energiebesparingsprojek te ondersoek soos bekend gemaak word tydens ’n verslagdoeningstydperk. Energiebesparingassesserings wat slegs gebaseer word op die suiwer deterministiese basislyn aanvraag na elektrisiteit, verteenwoordig nie die werklike statistiese aard van die besparingsimpakte van baie praktiese lasstelsels nie. Hierdie tesis stel die ontwikkeling van generiese waarskynlikheids-metodologie voor, om die voor- en na- Energiebesparings-maatreëls se aanvraagprofiele vir sulke praktiese lasstelsels, vas te stel. Die verskil tussen die gesimuleerde aanvraag van die voor- en na- Energiebesparings-maatreëls vir spesifieke stel veranderlikes verteenwoordig die elektriese aanvraag impak. Die voor- en na- Energiebesparings-maatreëls van die energieverbruik profieldata word gedefinieer in terme van Waarskynlikheidsdigtheidsfunksies en afgelei deur gebruik te maak van meerveranderlike kerndigtheidafskattingsalgoritme. Die benadering is getoets deur gebruik te maak van simuleringsmodel van warmwaterstelsel geïmplimenteer in MATLAB. Drie verskillende voor- en na- Energiebesparings-maatreëls is gesimuleer met behulp van die warmwaterstelselmodel en aanvraag digtheidafskatting. Die resultate van die elektriese aanvraag impakte van die voor- en na- Energiebesparings-maatreëls word vervolgens bespreek en geëvalueer. Met betrekking tot moontlike toekomstige navorsing kan hierdie metodologie toegepas word om die aanvraag impakte van hittepomp- en sonwaterverwarmingstegnologieë te evalueer.
