Greenhouse-gas emissions have become one of the most impacting environmental issues in today's society. A rapidly increasing trend in global CO2emissions particularly since the early nineties (23.64% since 1990) has led to the generation of about 50,000 million tons of CO2-equivalent (eqv) worldwide in 2010. According to mainstream climate experts, the increasing concentration of greenhouse-gases is having a warming effect on the world climate. To slow down global warming, there is a global focus on reducing greenhouse-gas emissions. Life cycle assessment in green building implementation is the focus of this Special Issue
This book develops a model to evaluate and assess life-cycle greenhouse gas emissions based on typical Australian commercial building design options. It also draws comparisons between some of the many green building rating tools that have been developed worldwide to support sustainable development. These include: Leadership in Energy and Environmental Design (LEED) by the United States Green Building Council (USGBC), Building Research Establishment Environmental Assessment Method (BREEAM) by the Building Research Establishment, Comprehensive Assessment System for Building Environmental Efficiency (CASBEE) by the Japanese Sustainable Building Consortium, and Green Star Environmental Rating System by the Green Building Council of Australia. Life-cycle assessment (LCA), life-cycle energy consumption, and life-cycle greenhouse gas emissions form the three pillars of life-cycle studies, which have been used to evaluate environmental impacts of building construction. Assessment of the life-cycle greenhouse gas emissions of buildings is one of the significant obstacles in evaluating green building performance. This book explains the methodology for achieving points for the categories associated with reduction of greenhouse gas emissions in the Australian Green Star rating system. The model for the assessment uses GaBi 8.7 platform along with Visual Basic in Microsoft Excel and shows the relationship between the building’s energy consumption and greenhouse gas emissions released during the lifetime of the building. The data gathered in the book also illustrates that the green building design and specifications are becoming more popular and are being increasingly utilized in Australia. This book is important reading for anyone interested in sustainable construction, green design and buildings and LCA tools.
Life-Cycle Cost Models for Green Buildings: With Optimal Green Star Credits illustrates the tools and methods for developing a life-cycle cost model that incorporates developer constraints while maximizing the number of credit points achieved. The book identifies the interdependencies among various credits in the Green Star environmental rating system. Afterwards, life-cycle cost is calculated by considering six main central business districts (CBDs) of Australia. The net present value (NPV) technique is used to calculate life-cycle costs. Further, a sensitivity analysis is also carried out for selected credits to identify the changes to life-cycle cost to the changes in discount rate. Once all the life-cycle cost data is calculated, this book illustrates the development of the proposed model using a Java application which allows users to evaluate each key criterion of green buildings separately. The book is designed to provide ample knowledge of the various options available to get green building certification and the further implications in-terms of life-cycle. - Provides cost saving and management advice for keeping a green building project operating on time and budget throughout their life-cycle - Expertly explains the various options available for gaining green building certification - Allows users to build life-cycle cost models which is unique to the project at hand
Life cycle assessment enables the identification of a broad range of potential environmental impacts occurring across the entire life of a product, from its design through to its eventual disposal or reuse. The need for life cycle assessment to inform environmental design within the built environment is critical, due to the complex range of materials and processes required to construct and manage our buildings and infrastructure systems. After outlining the framework for life cycle assessment, this book uses a range of case studies to demonstrate the innovative input-output-based hybrid approach for compiling a life cycle inventory. This approach enables a comprehensive analysis of a broad range of resource requirements and environmental outputs so that the potential environmental impacts of a building or infrastructure system can be ascertained. These case studies cover a range of elements that are part of the built environment, including a residential building, a commercial office building and a wind turbine, as well as individual building components such as a residential-scale photovoltaic system. Comprehensively introducing and demonstrating the uses and benefits of life cycle assessment for built environment projects, this book will show you how to assess the environmental performance of your clients’ projects, to compare design options across their entire life and to identify opportunities for improving environmental performance.
A building's entire life cycle aooOCU1/4oOe1/4o from construction through occupation, cycles of renovation and repairs, up to demolition and disposal, impacts the flow of materials thereby created. The decisive path of a building's environmental impact is however usually set early in the planning phase, at a time when planners often still lack knowledge about the sustainability characteristics of different building materials and constructions."
This book proposes an economic and environmental assessment tool to help private and public building designers and owners determine the global sustainability value of green buildings from a life cycle perspective. As it demonstrates, sustainable life cycle tools for building design and construction can help to achieve successfully integrated architecture. The first part of the book defines the relationship between environmental and economic aspects in a sustainable design approach and illustrates how life cycle methodologies, including Life Cycle Assessment and Life Cycle Costing, can be applied to life cycle design. Further, it highlights methods for calculating costs from LCA data, taking into consideration both discounted cash flow and external costs. In turn, the second part of the book presents an experimental design model, the Life Cycle Design Model (LCDM), which is based on a life cycle design approach that can be used to produce two different outcomes based on two assessment levels. The first assessment level involves creating a grid, called a Design Matrix, which is useful in the design process. The second assessment level involves drawing on LCA and LCC results to develop a user-friendly tool for designers and other actors involved in the building process so that they can assess the most sustainable design option using €CO, a factor that combines the environmental and energy effects of the building system with time and costs. Selected case studies illustrate the practical application of life cycle analysis and show how reflecting the environmental impacts and costs can improve the sustainability of buildings. The LCDM represents a transdisciplinary tool for the design team and, at the same time, allows information on users’ needs and building performance to be communicated between experts and non-experts.

The book explores how architectural, engineering and construction (AEC) firms have been adapting and changing to effectively address key environmental challenges, focusing on Life Cycle Thinking and related methodologies (Life Cycle Assessments and Life Cycle Costing). Starting from current practice, the book outlines the necessary change management to turn into life cycle AE(C) practice, switching from a product-technology mindset to a life cycle thinking and holistic approach. Although the primary audience of the book are Architectural and Engineering firms, the broad range of topics encourages readers from different backgrounds to explore the latest advancements in construction sector. Service companies and software developers can find inspiration to develop innovative tools and solutions, clients can find ways to demand sustainability as key target for building design and universities can align academic programmes to address new industry challenges.
