    Energy conservation is among society’s greatest challenges, and the built environment has a concentrated impact on our natural environment, economy, and health. Fundamental understandings of how energy is consumed, monitored, and controlled are key prerequisites for an energy conservation process. This paper evaluates the effectiveness of real-time energy monitors (RTM) to influence behavior change in residential consumers. A methodology for remote identification of load types along the electrical circuitry where they (load) are being consumed is also presented. The load type and status (on, off, standby) are determined both remotely and in a non-intrusive manner using Non-Intrusive Load Monitoring Methods. A bottom-up approach to real-time energy monitoring by integrating virtual and physical domains to increase user awareness on where, when, how and why aspect of energy to make inform decisions regarding energy consumption, optimization and conservation is proposed. A virtual 3-D environment is developed to display actual space/zone/building real-time power consumption information and to allow users to easily locate equipment/loads that are in standby/inefficient and causing energy waste in the real/physical environment. The proposed system using wireless ZigBee based monitoring system is demonstrated via a prototype board virtually integrated with a real world test environment. The results establish a promising tool in this filed

    Driving education for sustainable development potential within professional curricula: Built environment sustainability training and training development for professionals in Wales

    The Built Environment sector is responsible for 47% of all CO2 emissions, 90% of all surface mineral extraction and over 25% of all waste sent to landfill. In Wales, 30% of the carbon footprint comes from the built environment sector, a fact exacerbated also by having the highest proportion of pre-1919 building stock in the UK. None of these problems can be dealt with without having an appropriately skilled workforce, able to consider new technologies, applications and processes to deal with the problems of a rapidly changing built environment sector. This paper describes the work carried out by the Built Environment Sustainability Training Programme in Wales, designed to develop and deliver sustainability focussed training to Built Environment professionals, using an evidence-based approach. This involved the development of Skills needs analyses which outlined training needs within the sector for the short, medium and long term. Development of the courses is considered the best methods of delivery to attract the sector, including blended learning approaches. Underpinning course delivery is the consideration of the Education for Sustainable Development agenda, enabling recommendations for modification of existing courses offered by training delivery partners. Short-term results of the Built Environment Sustainability Training Programme include the delivery of new training courses that assist driving sustainability within the sector; whilst longer term results are anticipated as a culture shift in the practices used by the sector. The benefits to Wales are discussed in terms of achievement of policy measures, and recommendations are made for wider use of the methodology

    Construction IT in 2030: a scenario planning approach

    Get PDF
    Summary: This paper presents a scenario planning effort carried out in order to identify the possible futures that construction industry and construction IT might face. The paper provides a review of previous research in the area and introduces the scenario planning approach. It then describes the adopted research methodology. The driving forces of change and main trends, issues and factors determined by focusing on factors related to society, technology, environment, economy and politics are discussed. Four future scenarios developed for the year 2030 are described. These scenarios start from the global view and present the images of the future world. They then focus on the construction industry and the ICT implications. Finally, the preferred scenario determined by the participants of a prospective workshop is presented

    Building Information Modeling as Tool for Enhancing Disaster Resilience of the Construction Industry

    Get PDF
    As frequencies of the disasters are increasing, new technologies can be used to enhance disaster resilience performance of the construction industry. This paper investigates the usage of BIM (Building Information Modeling) in enhancing disaster resilience of the construction industry and in the establishment of the resilient built environment. In-depth literature review findings reveal BIM’s contribution to the disaster resilience in the pre-disaster and post-disaster phases especially through influencing the performance of the supply chain, construction process, and rescue operations. This paper emphasises the need for BIM’s integration to the education and training curriculums of the built environment professionals. Policy makers, construction professionals, professional bodies, academics can benefit from this research

    Zero and low carbon buildings: A driver for change in working practices and the use of computer modelling and visualization

    Get PDF
    Buildings account for significant carbon dioxide emissions, both in construction and operation. Governments around the world are setting targets and legislating to reduce the carbon emissions related to the built environment. Challenges presented by increasingly rigorous standards for construction projects will mean a paradigm shift in how new buildings are designed and managed. This will lead to the need for computational modelling and visualization of buildings and their energy performance throughout the life-cycle of the building. This paper briefly outline how the UK government is planning to reduce carbon emissions for new buildings. It discusses the challenges faced by the architectural, construction and building management professions in adjusting to the proposed requirements for low or zero carbon buildings. It then outlines how software tools, including the use of visualization tools, could develop to support the designer, contractor and user

    Optimizing the Structure and Scale of Urban Water Infrastructure: Integrating Distributed Systems

    Get PDF
    Large-scale, centralized water infrastructure has provided clean drinking water, wastewater treatment, stormwater management and flood protection for U.S. cities and towns for many decades, protecting public health, safety and environmental quality. To accommodate increasing demands driven by population growth and industrial needs, municipalities and utilities have typically expanded centralized water systems with longer distribution and collection networks. This approach achieves financial and institutional economies of scale and allows for centralized management. It comes with tradeoffs, however, including higher energy demands for longdistance transport; extensive maintenance needs; and disruption of the hydrologic cycle, including the large-scale transfer of freshwater resources to estuarine and saline environments.While smaller-scale distributed water infrastructure has been available for quite some time, it has yet to be widely adopted in urban areas of the United States. However, interest in rethinking how to best meet our water and sanitation needs has been building. Recent technological developments and concerns about sustainability and community resilience have prompted experts to view distributed systems as complementary to centralized infrastructure, and in some situations the preferred alternative.In March 2014, the Johnson Foundation at Wingspread partnered with the Water Environment Federation and the Patel College of Global Sustainability at the University of South Florida to convene a diverse group of experts to examine the potential for distributed water infrastructure systems to be integrated with or substituted for more traditional water infrastructure, with a focus on right-sizing the structure and scale of systems and services to optimize water, energy and sanitation management while achieving long-term sustainability and resilience
