    Forecasts point to a huge increase in energy demand over the next 25 years, with a direct and immediate impact on the exhaustion of fossil fuels, the increase in pollution levels and the global warming that will have significant consequences for all sectors of society. Irrespective of the likelihood of these predictions or what researchers in different scientific disciplines may believe or publicly say about how critical the energy situation may be on a world level, it is without doubt one of the great debates that has stirred up public interest in modern times. We should probably already be thinking about the design of a worldwide strategic plan for energy management across the planet. It would include measures to raise awareness, educate the different actors involved, develop policies, provide resources, prioritise actions and establish contingency plans. This process is complex and depends on political, social, economic and technological factors that are hard to take into account simultaneously. Then, before such a plan is formulated, studies such as those described in this book can serve to illustrate what Information and Communication Technologies have to offer in this sphere and, with luck, to create a reference to encourage investigators in the pursuit of new and better solutions

    Evaluating building energy performance: a lifecycle risk management methodology

    There is widespread acceptance of the need to reduce energy consumption within the built environment. Despite this, there are often large discrepancies between the energy performance aspiration and operational reality of modern buildings. The application of existing mitigation measures appears to be piecemeal and lacks a whole-system approach to the problem. This Engineering Doctorate aims to identify common reasons for performance discrepancies and develop a methodology for risk mitigation. Existing literature was reviewed in detail to identify individual factors contributing to the risk of a building failing to meet performance aspirations. Risk factors thus identified were assembled into a taxonomy that forms the basis of a methodology for identifying and evaluating performance risk. A detailed case study was used to investigate performance at whole-building and sub-system levels. A probabilistic approach to estimating system energy consumption was also developed to provide a simple and workable improvement to industry best practice. Analysis of monitoring data revealed that, even after accounting for the absence of unregulated loads in the design estimates, annual operational energy consumption was over twice the design figure. A significant part of this discrepancy was due to the space heating sub-system, which used more than four times its estimated energy consumption, and the domestic hot water sub-system, which used more than twice. These discrepancies were the result of whole-system lifecycle risk factors ranging from design decisions and construction project management to occupant behaviour and staff training. Application of the probabilistic technique to the estimate of domestic hot water consumption revealed that the discrepancies observed could be predicted given the uncertainties in the design assumptions. The risk taxonomy was used to identify factors present in the results of the qualitative case study evaluation. This work has built on practical building evaluation techniques to develop a new way of evaluating both the uncertainty in energy performance estimates and the presence of lifecycle performance risks. These techniques form a risk management methodology that can be applied usefully throughout the project lifecycle

    HBIM: Low-cost sensors and environmental data in heritage buildings - A guide for practitioners and professionals

    Get PDF
    This guide is intended to introduce the heritage conservation professional to the use of low cost sensors to capture environmental data in occupied heritage buildings, for the purposes of enhancing the heritage preservation practice with the capability for real-time monitoring and analysis of the buildings state.The first part of this document is an introduction to the applications of sensors and data capture in buildings, followed by a more detailed discussion of the particular variables to be captured and the technology available. The second part is a guide to choosing equipment, deployment, and using the captured data, with recommendations for best practice

    Developing the system of collecting, storing and processing information from solar collectors

    В данной статье представлена новая методика управления системой сбора, хранения и обработки информации от солнечных коллекторов, которая может применяться для обогрева промышленных и бытовых отсеков для горячего водоснабжения. Наиболее выгодное использование солнечных коллекторов в промышленности - замена помех от человека сетями беспроводных датчиков. Стандартная система солнечного коллектора потребляет в среднем 30% тепла из-за плохого управления и конфигурации. Наша система контроля и управления позволяет повысить производительность обогрева производственных и бытовых помещений с помощью солнечного коллектора для горячего водоснабжения
