In Australia, cost-benefit analysis (CBA) is one of the conventional tools used widely by the public and the private sectors in the appraisal of projects. It measures and compares the total costs and benefits of projects that are competing for scarce resources in monetary terms. Growing concerns that the values of environmental goods and services are often ignored or underestimated in the CBA approach have led to the overuse and depletion of environmental assets. A model of a sustainability index as an evaluation tool that combines economic, social and environmental criteria into an indexing algorithm is presented and described. The sustainability index uses monetary and non-monetary approaches to rank projects and facilities on their contribution to sustainability. This process enables the principle of trade-off to occur in the decision-making process and thereby allows environmental values to be considered when selecting a development option. This makes it possible to optimize financial return, maximize resource consumption and minimize detrimental effects to the natural and man-made world. A case study is used to demonstrate the model. 相似文献

This paper introduces market mechanisms for sustainable community development, an interdependent planning and implementation framework encompassing strategic directions, strategies, actors and instruments for municipal policy making. It examines how the economy influences the unsustainable development of local jurisdictions and how a coherent typology of strategies, actors and policy levers can move communities toward complementary environmental, social and economic outcomes. The paper illustrates a dichotomy between municipal decision making and embraces economic, social and environmental criteria for development of the built environment. It defines sustainable community development and analyzes research findings from senior decision makers in government, academic institutions, industry and non-profits. After critiquing ‘the market mechanism’ and identifying preferred approaches, the authors propose a typology that systematically aligns market signals with implementing sustainable community development policies. 相似文献

A recently developed framework to provide a logical structure for the a priori assessment of a particular technology with regard to sustainability concepts, performance, and relevancy to a project's construction process and operation is introduced. The framework is designed to assist project stakeholders and policy-makers in systematically identifying and evaluating the implications and relative merits of a range of alternative sustainable technologies. Building professionals were consulted throughout the development of the framework: to test the completeness of the framework; to capture the value systems of various industry participants in order to reflect them in the framework; and to gather information on the advantages and disadvantages of the green roof technology. The framework is applied to the example of the green roof technology, and the order-of-magnitude estimates are developed for performance measures identified as important from the perspective of industry professionals. The technology is evaluated for different configurations of the same building type to demonstrate the effect of building context on performance. The framework can be used to assist in the assessment of the positive and negative implications of a particular technology with respect to value systems and context, and, therefore, may be used to explain market behaviour, assist policy-makers in developing meaningful regulations and incentives, and provide feedback regarding a new technology in an objective manner. L'auteur présente un cadre qui a été récemment développé pour offrir une structure logique destinée à l'évaluation a priori d'une technologie particulière en ce qui concerne les concepts de durabilité, les performances et la pertinence eu égard au processus de construction et à l'exploitation d'un projet. Ce cadre est conçu pour aider les acteurs d'un projet et les décideurs à identifier et évaluer de manière systématique les implications et les avantages relatifs d'une panoplie de technologies durables alternatives. Durant toute la période de développement du cadre, on a consulté des professionnels de la construction; l'objectif était de tester l'aspect complet du cadre, de capturer les systèmes de valeur des divers participants industriels pour qu'ils soient présents dans le cadre et de collecter des informations sur les avantages et les inconvénients de la technologie des terrasses végétalisées. Ce cadre s'applique à la technologie des terrasses végétalisées et les estimations de l'ordre de grandeur sont calculées pour des mesures de performances importantes aux yeux des professionnels de cette industrie. Cette technologie est évaluée pour différentes configurations d'un même type de bâtiment afin de démontrer les effets du contexte du bâtiment sur les performances. Le cadre peut servir à aider à évaluer les implications positives et négatives d'une technologie donnée par rapport aux systèmes de valeur et au contexte et peut donc être utilisé pour expliquer le comportement du marché, pour aider les décideurs à formuler des règlementations et des incitations significatives et pour fournir de manière objective un retour d'information sur une nouvelles technologie.

A response is presented to the dilemma of hosting resource-intensive large-scale sporting events at a time when requirements for sustainability and sustainable development must also be met. A framework was devised for judging development and design issues for future planning, one which is based upon extant historic evidence from host city experiences as well as previous event outcomes. It offers potential to compare plans against best/optimal practice. The technique for appraisal arises from a detailed analysis of Olympic Games held since 1896. Data associated with venue design, construction and usage, athletes' accommodation, and the facilities for officials, the media and visitors/spectators, were amassed and reviewed. An evaluation technique was produced which demonstrates how the organizers of a modern Olympic Games can assess and reflect upon planning, design and development decisions associated with their own city from an early outline stage. This should permit less wasteful, more appropriate and more sustainable Games' infrastructures to be considered before complex detailed development occurs. 相似文献

A simulation model based on classical population dynamics is developed to estimate the benefit‐cost ratio performance of different typologies of housing with the purpose of identifying potential reductions in the total costs and hence resources used to sustain housing. A typical New Zealand dwelling constructed of lightweight timber framing is used as an example. Dwellings within the simulation model undergo periodic cycles of refurbishment based on best practices. When the simulated housing stock expands at the rate of 1.5% per year, an annual expenditure equivalent to the costs to construct one dwelling sustains the services provided by 26.7 dwellings after adjustment for economic depreciation. This benefit‐cost ratio performance improves by 32.4% when the housing stock is stationary. Further improvements of 5.3% can be achieved by deferring refurbishment and accepting a higher level of economic depreciation of dwelling services. The results of all scenarios indicate that structural systems with a service life of only 50 years should not be used unless the costs of such systems are substantially less than the costs of traditional structural systems and that lightweight timber framed dwellings should not be sustained well beyond a service life of 90 years. 相似文献

ABSTRACTThe United Nations’ (UN) sustainable development goals (SDGs), the core of the 2030 Agenda for Sustainable Development and the UN Paris Agreement, were adopted in 2015. Involvement of not only national governments but also all other stakeholders including local governments is important to promote sustainable development and to achieve the goals. The question arises, therefore, of what methods should be used to best implement and assess sustainability issues at a local level. In this light, a new version of Comprehensive Assessment System for Built Environment Efficiency (CASBEE), CASBEE for Cities, is introduced for assessing the sustainability of cities and communities around the world based on SDG indicators and greenhouse gas (GHG) emissions. The tool allows users to understand the sustainability of cities and communities based on quality (Q) and environmental load (L) perspectives. The sustainability assessments show that cities in developed countries tend to have good grades for Q, but bad grades for L, while cities in developing countries tend to have the opposite trend. This will assist cities and communities in both developed and developing countries to understand urgent problems and to identify effective solutions for sustainable development. 相似文献

ABSTRACTIn the design and operations industries, the performance gap is a common discrepancy found between predicted building energy performance and actual energy performance. The performance gap is considered to have negative impacts for the brand of ‘green’ buildings, designers and operators. A socially based analogue is proposed here: the qualitative performance gap, defined as the perceived gap between what inhabitants expect and their actual experience of the building environment. This concept is explored at a regenerative Living Lab: the Centre for Interactive Research on Sustainability (CIRS) in Vancouver, Canada. ‘Official’ and ‘lived’ stories about the building were interpreted from sources of building information and interviews. Expectations about and forgiveness of building performance were gained from pre- and post-occupancy evaluations and interviews. The solution to the qualitative performance gap is not to eliminate it, but, in line with the concept of interactive adaptivity, to use the gap to generate new stories and new consequences for human wellbeing. The qualitative performance gap is thus conceived as positively generative, of new stories of place and identity. This work recommends crafting an ‘official story’ of social aspirations, and a communication feedback loop amongst designers, operators and building inhabitants, transparently sharing successes and failures. 相似文献

ABSTRACTSince the 1970s, intense discussions have occurred within the research and practitioner communities on how to assess and influence the environmental performance of buildings. Many different methods, criteria and tools were developed to raise awareness, enable goal formulation, support design and decision-making processes, and evaluate a building’s environmental performance. This development can be retraced through the example of the works of Raymond J. Cole, who made an important contribution to this scientific debate. The integration of environmental performance into a sustainability assessment, the ongoing development of life cycle assessment (LCA) methods, and clients’, financiers’ and assessors’ different demands for environmental performance assessment, raise additional questions and highlight the conflicting goals. Six topics are examined in relation to current developments: the further development of the classic ‘three pillars’ sustainability model; the suitability of assessment criteria and indicators; the handling of technological progress; the discounting of environmental impacts; the environmental assessment of existing buildings; and the further development of legal requirements. ‘Time’ is a key factor relating to LCA, weighing current versus future emissions, ecological value and recycling potential of existing buildings or ‘options’ for different ways to use the building in future. Recommended actions are provided for key stakeholders. 相似文献
