Book excerpt: The importance and benefits of knowledge management (KM) and change management (CM) have been increasingly recognized in the Architecture, Engineering and Construction (AEC) Industry. A large proportion of the problems on construction projects emanate from the lack of appropriate mechanisms to effectively manage knowledge, changes and dependencies. Changes can alter service or product variables, and it is challenging to manage the impacts of changes and the associated dependencies. Traditional manual methods of managing changes are inefficient and do not fully engage all team members or adequately capture the rationale for changes. In energy efficient retrofits, inadequate management of changes could have negative impacts on building energy performance. In addition, knowledge is often generated as part of the change management process. Given that knowledge has become a fundamental resource for organizations and can provide organizations with competitive advantages, it is imperative that any new knowledge generated from change management is captured and disseminated.The aim of this research is to investigate the feasibility of an integrated approach to managing change and knowledge in energy efficient retrofit projects. In order to understand theoretical perspective and similar work in change and knowledge management, a detailed review of literature was conducted. The review was based on the most important aspects of knowledge management, change and dependency management, and their applications in construction. Two case studies were undertaken using individual interviews, focus group interviews and questionnaires to investigate challenges and current practices of managing changes, dependencies and knowledge in the AEC Industry.An Integrated Change and Knowledge Management (ICKM) approach was developed to address the challenges of change and knowledge management, and provide an effective mechanism for simultaneously managing changes and knowledge in energy efficient retrofit projects. The integrated approach established a systematic way to facilitate change and dependency management, capture lessons learned during change management processes, and support information exchange between different disciplines in change and knowledge management activities. To demonstrate the feasibility and potential benefits, the ICKM approach was implemented in the overall construction workflows and Building Information Modeling (BIM), and two case studies were conducted to investigate current challenges and the need for an integrated approach, and validate the feasibility of the ICKM approach.Based on the ICKM approach, a prototype system - the Integrated Change and Knowledge Management System (ICKMS) was developed to automate the ICKM process. System requirements, use cases, components and techniques were identified in the research. The prototype was developed as a Web-based system for easy access and maintenance, which is composed of two sub-systems: a change management system (CMS) to support CM processes and a knowledge management system (KMS) to support KM processes. Capri.net was adopted as the KMS in the prototype. The use of the integrated system in energy efficient retrofit projects is expected to improve the efficiency and effectiveness of simultaneously managing changes and knowledge.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of the built environment in tackling current energy and sustainability challenges is widely recognized. There is significant value in retrofitting existing buildings. Owners, project managers, designers, and contractors now actively seek opportunities to upgrade the energy performance of standing buildings. These prospects lie in the retrofit process, within which many collaborative decisions take place at critical stages. The procedure is currently inefficient, with decision makers unaware early in the process of the ultimate implications of their actions on the energy-efficiency outcomes of the building they are creating. Thus, there is substantial room for a decision support system (DSS) that can guide facility owners and project managers in undertaking advanced energy retrofits of existing buildings by considering effects of decisions on energy performance. Approaches that support decision-making prediction in energy performance include checklists, databases, and forward and inverse modeling. We know that integrated system upgrades result in more significant energy reduction rates than do standard approaches. Because all team members do not inform these synergies early in the process, however, energy-efficient decisions do not occur. In a typical energy-efficient retrofit design, decisions are entered into simulations without collaboration to document them and predict the design's energy performance. Such late evaluations cannot go beyond the projection of energy performance that is already selected for the design. Thus, there is a need for a decision-support system that stimulates both the collaborative design process and early decision-making on system performance information.The research methodology consisted of a literature review on critical design activities and energy conservation measures (ECM) as the first stage, followed by interview design and testing the need statement with experts. Then we collected decision variables through involvement in case-study meetings and interviews with project participants. For the process delineation, we mapped three "as is" process models to cross-case with recommendations from the literature, and delivered a "to be" process model. The refined "to be" process model we offer is also fed by the ECM measure that is tracked in case studies, project participant interviews, and project documents. To inform the design team lead by PMs, a simplified comparative energy-consumption prediction methodology is developed. Consequently, this research creates a project management DSS to manage the deep-retrofit process during collaboration meetings and design charrettes. It aims to improve the integrated design process by providing a just-in-time relative energy analysis compared to a standard baseline. This energy-efficiency prediction methodology is scalable to other project values such as IEQ or cost. The knowledge we add to the field combines process with critical ECM performance measures. The opportunity to have a comparative energy analysis of decisions early in the design process will also improve system option opportunities and present the ability to change them.

Download or read book Retrofitting the Built Environment written by William Swan and published by John Wiley & Sons. This book was released on 2013-08-06 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: The physical upgrading of the existing domestic and industrial building stock to improve energy performance is an essential part of a transition to a low carbon society. Successfully retrofitting buildings to improve energy performance is not simply a technological challenge, it is a complex socio-technical problem that needs to be addressed in a co-ordinated way, utilising skills and knowledge from a range of industrial and academic backgrounds. Within both the academic and practitioner communities there is a growing understanding of the scale and nature of the problem, one which encompasses issues such as policy and regulation, people and behaviour, supply chain and process, as well as issues of technology. Retrofitting the Built Environment discusses the factors that impact on the retrofit problem, providing a clear analysis of the main issues that the academic and industrial communities must engage with to resolve the problems of domestic energy and retrofit. The book is divided into four broad sections: Understanding the Problem Policy and Regulation Implementing and Evaluating Retrofit People and Communities Academic and industrial researchers, policy makers and industry practitioners will find each section covers a mix of policy, technical and social science issues, presented by both academic and industry authors, giving a wide and detailed perspective of the issue. The Editors Will Swan is a Senior Lecturer in Buildings Retrofit in the School of the Built Environment at the University of Salford.

Book Synopsis Cost-Effective Energy Efficient Building Retrofitting by : F. Pacheco-Torgal
Download or read book Cost-Effective Energy Efficient Building Retrofitting written by F. Pacheco-Torgal and published by Woodhead Publishing. This book was released on 2017-01-03 with total page 633 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cost-Effective Energy Efficient Building Retrofitting:Materials, Technologies, Optimization and Case Studies provides essential knowledge for civil engineers, architects, and other professionals working in the field of cost-effective energy efficient building retrofitting. The building sector is responsible for high energy consumption and its global demand is expected to grow as each day there are approximately 200,000 new inhabitants on planet Earth. The majority of electric energy will continue to be generated from the combustion of fossil fuels releasing not only carbon dioxide, but also methane and nitrous oxide. Energy efficiency measures are therefore crucial to reduce greenhouse gas emissions of the building sector. Energy efficient building retrofitting needs to not only be technically feasible, but also economically viable. New building materials and advanced technologies already exist, but the knowledge to integrate all active components is still scarce and far from being widespread among building industry stakeholders. Emphasizes cost-effective methods for the refurbishment of existing buildings, presenting state-of-the-art technologies Includes detailed case studies that explain various methods and Net Zero Energy Explains optimal analysis and prioritization of cost effective strategies
Book Synopsis Deep Energy Retrofit Guide for Public Buildings by : Rüdiger Lohse
Download or read book Deep Energy Retrofit Guide for Public Buildings written by Rüdiger Lohse and published by Springer. This book was released on 2019-04-10 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides detailed information on how to set up Deep Energy Retrofits (DERs) in public buildings, and shares in-depth insights into the current status of the major technologies, strategies and practical best practice examples of how to cost-effectively combine them. Case studies from Europe are analyzed with respect to energy use before and after renovation, reasons for undertaking the renovation, co-benefits achieved, resulting cost-effectiveness, and the business models employed. The building sector holds the potential for tremendous improvements in terms of energy efficiency and reducing carbon emissions, and energy retrofits to the existing building stock represent a significant opportunity in the transition to a low-carbon future. Moreover, investing in highly efficient building materials and systems can replace long-term energy imports, contribute to cost cutting, and create a wealth of new jobs. Yet, while the technologies needed in order to improve energy efficiency are readily available, significant progress has not yet been made, and “best practices” for implementing building technologies and renewable energy sources are still relegated to small “niche” applications. Offering essential information on Deep Energy Retrofits, the book offers a valuable asset for architects, public authorities, project developers, and engineers alike.
Book Synopsis Retrofit for Purpose by : Greg Penoyre
Download or read book Retrofit for Purpose written by Greg Penoyre and published by Routledge. This book was released on 2019-07-25 with total page 581 pages. Available in PDF, EPUB and Kindle. Book excerpt: Retrofit for Purpose examines a range of state-of-the-art non-domestic retrofit projects. Its chapters explore common challenges, offer practical solutions and provide a clarion-call to architects and clients for better, smarter retrofit. Twelve case studies focus as much on the transformation of usability and image as on the improvements in the energy and resource use of non-domestic buildings. While an essay section places these projects into a wider context, suggesting that despite the importance of sharing and analysing data, there is more to retrofit than just energy efficiency. The authors take a range of other retrofit variables: from client ambition to tenure, budget, use type, age, context, fashion and fiscal arrangements and assess how retrofit can be made affordable, how it fits in with wider government policy and how performance can be measured.
Book Synopsis Retrofitting Cities by : Mike Hodson
Download or read book Retrofitting Cities written by Mike Hodson and published by CRC Press. This book was released on 2015-12-14 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Developing an up-to-date critical framework for analysing urban retrofit, this is the first book to examine urban re-engineering for sustainability in a socio-technical context. Retrofitting Cities examines why retrofit is emerging as an important strategic issue for urban authorities and untangles the mix of economic, competitive, ecological and social drivers that influence any transition towards a more sustainable urban environment. Retrofitting Cities comparatively explores how urban scale retrofitting can be conceptualised as a socio-technical transition; to critically compare and contrast different national styles of response in cities of the north and global south; and, to develop new research and policy agendas on future development of progressive retrofitting. Bringing together a group of researchers from a variety of disciplinary backgrounds that reflect the complexity of the research challenge, Retrofitting cities looks across different infrastructures and types of built environment, dealing with diverse urban contexts and examining formal as well as community responses. This is a uniquely practical book for urban planning and policy professionals as well as for researchers in urban studies and urban design.

Book excerpt: Nowadays the buildings are responsible for the 40% of the world energy. The key aspects to design energy efficient buildings arises from a variety of factors and external pressures such as legislation, emissions of ozone depleting gases and public awareness of the pollution of our planet. There is a great need, among public and private sectors, to improve the energy performance of existing public buildings. Specifically indoor air quality, energy efficiency and thermal comfort conditions are the three main considerations for the good performance of buildings. Existing buildings tend to undergo performance degradations, change in use, and unexpected faults or mal - functions over time. These events often result in significant deterioration of the overall system performance, inefficient operation and unacceptable thermal comfort conditions. However, a building does not have to be new to be efficient. Today's leading building owners are retrofitting buildings, and converting existing buildings into models of sustainability. Commercial retrofit offers significant opportunities for energy efficiency and sustains - ability in the built environment. Design of energy-efficient and high-performance commercial retrofit requires that building performance and simulation tools are used and integrated with the design process.Cost-Effective Energy Efficient Building Retrofitting aims to provide building researchers and practitioners with a better understanding of how to effectively conduct commercial retrofit to promote energy conservation and sustainability including real world cases. Several general design strategies are provided in the successful completion of sustainable and energy efficient retrofit projects. It explores the current market size and why the building retrofit market has not expanded as much in past years. Review of past practice and research efforts reveals that though a building retrofit project, especially a deep retrofit project is no different than any investment case in business practice, past retrofit projects are rarely motivated and convinced by the cost-effectiveness of the project but more by building owners' desire to "green" the building.

This book was released on 2009-12-09 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: An organisation’s competitive advantage lies in the knowledgeof its employees and the organisation’s ability to harnessthat knowledge to meet business objectives. Knowledge management isrecognised in the construction industry as a potential tool forproviding organisational benefits, but for a number of reasons– particularly the project based nature of construction,where teams are transient, multidisciplinary and often fromdifferent organisations – implementation has been onlymarginally successful. Capture and Reuse of Project Knowledge in Construction describesa methodology for the 'live' capture of reusable project knowledgethat reflects both the organisational and human dimensions ofknowledge capture and reuse, as well as exploiting the benefits oftechnology. This methodology was developed in response to theshortcomings of current practices in managing project knowledge,the benefits offered by capturing and sharing knowledge immediatelyafter it is generated, and the organisational benefit of reusingknowledge within a project based environment.

Available in PDF, EPUB and Kindle. Book excerpt: Many governments worldwide are setting more stringent targets for reductions in energy use in government/public buildings. Buildings constructed more than 10 years ago account for a major share of energy used by the building stock. However, the funding and "know-how" (applied knowledge) available for owner-directed energy retrofit projects has not kept pace with new requirements. With typical retrofit projects, reduction of energy use varies between 10 and 20%, while actual executed renovation projects show that energy use reduction can exceed 50%, and can cost-effectively achieve the Passive House standard or even approach net zero-energy status (EBC Annex 61 2017a, Hermelink and Müller 2010; NBI 2014; RICS 2013; Shonder and Nasseri 2015; Miller and Higgins 2015; Emmerich et al. 2011). Building energy efficiency (EE) ranks first in approaches with resource efficiency potential with a total resource benefit of approximately $700 billion until 2030. EE is by far the cheapest way to cut CO2 emissions (McKinsey 2011, IPCC 2007). However, according to an IEA study (IEA 2014a), more than 80% of savings potential in building sector remains untapped. Thus, the share of deployed EE in the building sector is lower than in the Industry, Transport, and Energy generation sectors. Estimates for the deep renovation potentials show: €600-900bn investment potential, €1000-1300bn savings potential, 70% energy-saving potential, and 90% CO2 reduction potential.

Book excerpt: Energy risk has reappeared on the corporate and social agenda with a bang and the complexity of the issues has increased many-fold since the days of the last great wave of concern following the oil crises of the 1970s. Steven Fawkes’ Energy Efficiency is a comprehensive guide for managers and policy-makers to the fundamental questions underpinning energy-efficiency and our responses to it: ¢ what do we really mean by energy efficiency? ¢ what is the potential (in different dimensions)? ¢ why it is important? ¢ what management processes lead to optimisation of energy efficiency? ¢ what technologies are useful for improving energy efficiency? ¢ what policies can be used to promote energy efficiency? ¢ how can energy efficiency be financed? ¢ how can energy suppliers engage with energy efficiency? The result is the most comprehensive review to-date of the barriers and opportunities associated with improving energy efficiency. Clearly written and erudite, Steven Fawkes addresses every aspect of energy efficiency, including the huge and vitally important untapped potential offered by effective energy management and the application of existing technology. He also identifies barriers, such as the rebound effect and how they can be mitigated and he provides a comprehensive review of innovative energy efficiency financing options. This book is a ’must read’ for anyone with an interest in energy supply and demand reduction.

Download or read book Passive Energy Conservation Management in Retrofit Buildings written by Amiri Fard Farhad and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A significant share of the total primary energy belongs to buildings. In many buildings, improving energy performance of buildings is of particular importance in new construction and existing buildings. Building refurbishment is considered a practical pathway towards energy efficiency as the replacement of older buildings is at a slow pace. There are various ways of incorporating energy conservation measures in buildings through refurbishment projects. In doing so, we have to choose among various passive or active measures. The energy usage can be significantly reduced by adopting passive measures. These methods might not need additional capital investment. An integrated building renovation approach, in which passive methods are implemented, can reduce the energy consumption of building, compensating the additional cost of new technologies. This thesis aims at developing an integrated assessment-optimization framework to provide a decision support for prioritization and selection of building refurbishment measures with energy conservation potentials by considering the cost uncertainty. Firstly, a literature review is carried out to ascertain the state of the art in the retrofit decisions in buildings at the presence of several decision criteria. possible and available passive measures are investigated and identified based on four energy control principles. Secondly, the analytic network process (ANP) is reviewed as a multiple criteria decision-making method capable of incorporating the interdependencies among decision criteria to arrive at an overall assessment (relative scores) for alternative retrofit measures. To incorporate uncertainties in formulating the initial cost of materials, a fuzzy set approach is adopted. Then, the scores resulted from the assessment phase are formulated a utility objective function to be maximized alongside the cost objective function(s) that are minimized. The fuzzy numbers representing the cost uncertainties are incorporated into the cost objective function using alternative methods of graded mean integration, aggregate approach and interval approach. Various Solution approaches are then utilized for the multi-objective models to deal with the conflicting objectives including distance to ideal, compromise programming and goal programming. The cases of linear and integer assumptions about decision variables are investigated. The applicability of the proposed three-stage assessment-optimization approach under uncertainty is then illustrated through the case study of a typical building in order to verify its applicability and usefulness and the solution scenarios are explored and compared The proposed framework can assist decision makers in choosing the best passive measures in the planning phase of the building refurbishment addressing the complexities arising from multiplicity of feasible measures and their varied characteristics.Finally, in terms of the impact of the above research, it worth mentioning that 40% of final energy is used in buildings and the use of passive measures as a means of refurbishment for building stocks could create significant energy efficiency gains.
