The recent availability of very low power (e.g., battery powered) wireless sensors, networks and personal communication devices has enabled the exploration of wireless systems for both monitoring personal energy use and for feeding back the information directly to individuals responsible. These are based on static wireless sensors utilising low cost, small, low power digital radio (ZigBee) and real-time user location sensors using RFID and Ultra-wideband (UWB) radio frequency technologies. Low cost, low power, user feedback technologies include Ekahau Wi-Fi based devices and mobile phones.The Wi-be system is truly user-centric and promises huge potential for instigating behaviour change and substantial energy demand reduction: it complements the smart metering technology and takes a significant step further in helping to identify specific wasteful energy use, actions to take and the persons to take them. Unlike the smart meter, which is expected to provide overall consumption data in specific feedback formats [11], the Wi-be approach forms a people/building energy technology interface that promises much greater energy behaviour changes that are widely replicable and adaptable to future energy technology scenarios. When implemented and used over a period of time, it could potentially bring about a durable behavioural change leading to efficient energy uses.However, development of this technology gives rise to inter-related challenges spanning ICT, building energy and user behaviour, which so far are largely being researched in isolation. What is required is a multi-disciplinary study to bring about a step change in the understanding of Wi-be technology to ensure its effectiveness and successful uptake. Based on a new collaboration, the study will provide tools, guidance and vastly improved understanding for effective implementations of the technology that would result in durable and significant reduction of energy demand. Specific objectives include:1. Construct a state-of-the-art very-low-power Wi-be system for monitoring and communicating personal energy behaviours in both domestic and non-domestic buildings. This will involve both in-building and on-body sensors and will be installed in an office building and a house, to be used as test beds for the integrated research:2. Conduct cross-disciplinary assessment of Wi-be by integrating the following: a. Sensor Network Research - determining what is practical, in terms of building and body sensors, in order to capture energy-inefficient behaviour; b. Wireless Research - modelling of wireless sensor signal propagation to ascertain the optimum configurations (e.g., location, power levels) and potential limitations to physical deployment of wireless sensors, network and other related communication devices operating at very low power (and consequently very long battery life); c. Behavioural Research - determine the optimum feedback interface, format and timing of sensor data presentation to individual energy users in order to achieve the best effects on stimulating immediate action and durable behavioural change; d. Building Energy Research - to assess interactions between building energy demand, supply and user behaviour, as well as benchmarks, and their implications for optimum arrangement for feedback to users;3. To engage users, manufacturers and other stakeholders to ensure quality and relevance of the results and their effective dissemination for commercial deployment. Dissemination of the integrated methodology, established in this feasibility study, will permit future deployment into large scale assessments and commercial exploitation.

最近可用的非常低的功率（例如，电池供电的）无线传感器、网络和个人通信设备已经使得能够探索用于监视个人能量使用和用于将信息直接反馈给负责的个人的无线系统。这些都是基于静态无线传感器利用低成本，小，低功耗数字无线电（ZigBee）和实时用户位置传感器使用RFID和超宽带（UWB）射频技术。低成本、低功耗、用户反馈技术包括基于Ekahau Wi-Fi的设备和移动的电话。Wi-be系统真正以用户为中心，并有望激发行为改变和大幅减少能源需求：它补充了智能计量技术，并在帮助识别特定浪费能源使用、应采取的行动和应采取行动的人员方面迈出了重要的一步。与智能电表不同，智能电表预计将以特定的反馈格式提供总体消费数据[11]，Wi-be方法形成了一个人/建筑物能源技术界面，承诺更大的能源行为变化，可广泛复制和适应未来的能源技术方案。当实施和使用一段时间后，它可能会带来持久的行为改变，从而提高能源利用效率。然而，这项技术的发展带来了跨越ICT、建筑能源和用户行为的相互关联的挑战，到目前为止，这些挑战在很大程度上是孤立的研究。所需要的是一个多学科的研究，带来一个步骤的变化，在Wi-be技术的理解，以确保其有效性和成功的吸收。基于新的合作，该研究将为有效实施该技术提供工具，指导和大大改善的理解，从而持久和显着地减少能源需求。具体目标包括：1.构建一个最先进的极低功耗Wi-be系统，用于监控和传达住宅和非住宅建筑中的个人能源行为。这将涉及建筑物内和身体上的传感器，并将安装在办公楼和住宅中，用作综合研究的测试平台：2。通过整合以下内容对Wi-be进行跨学科评估：a.传感器网络研究-确定在建筑物和人体传感器方面什么是实际的，以便捕获能源效率低下的行为; B.无线研究-无线传感器信号传播的建模，以确定最佳配置（例如，位置、功率水平）和对以非常低的功率（并且因此非常长的电池寿命）操作的无线传感器、网络和其他相关通信设备的物理部署的潜在限制; c.行为研究--确定向个人能源用户呈现传感器数据的最佳反馈接口、格式和时机，以便在刺激立即行动和持久行为改变方面取得最佳效果; d.建筑物能源研究-评估建筑物能源需求、供应和使用者行为之间的相互作用，以及基准，以及它们对优化用户反馈安排的影响;3.让用户、制造商和其他利益相关者参与进来，以确保结果的质量和相关性，并确保其有效传播以进行商业部署。传播本可行性研究中确定的综合方法，将有助于今后在大规模评估和商业开发中加以应用。
