Commercial buildings are central to cities and contribute significantly to the urban demand for natural resources, including freshwater. Green building benchmarking tools include more efficient water use as key indicator of sustainability. This paper explores options for substituting mains drinking water with an alternative, non-potable water source on a fit for purpose basis. The research findings are based on a monitoring study of a commercial building in Brisbane, Australia that is harvesting rainwater for meeting non-potable water demand. The results demonstrated that the system is only achieving moderate reliability in meeting demand due to operational problems. The case study analysis has highlighted the need to include validation and monitoring to ensure the system is operating as per design intent. The paper also investigates the potential of other local, non-potable water sources for high-rise commercial buildings, in particular air conditioning condensate and groundwater inflow to a basement wet well. The paper concludes by comparing the advantages and disadvantages of different local water sources which highlights the need to undertake a site specific investigation to identify a suitable alternative water source, which considers O&M complexity and the capacity of facilities management.  相似文献

Wang, Jinxia, Jikun Huang, Lijuan Zhang, Qiuqiong Huang, and Scott Rozelle, 2010. Water Governance and Water Use Efficiency: The Five Principles of WUA Management and Performance in China. Journal of the American Water Resources Association (JAWRA) 46(4): 665-685. DOI: 10.1111/j.1752-1688.2010.00439.x Abstract: In recent years China has attempted to reform water management by decentralizing water management responsibilities. The overall goal of our paper is to better understand the emergence of water user associations (WUAs) in China and assess if they are adhering to the practices spelled out by the Five Principles, a set of recommended practices that are supposed to lead to successful WUA operation. Using four sets of different types of villages to examine implementation and performance, we find that World Bank-supported WUA villages (“Bank villages”) can be thought of as operating mostly according to the Five Principles. For example, the Bank villages were endowed with a more reliable water supply; were set up and were operating with a relatively high degree of farmer participation; and leaders were more consultative and the process more formal. When WUAs are run according to the Five Principals, we show that WUAs increase water use efficiency. The study also provides evidence that there is a perception in the Bank villages that water management is improving in general and that there is less conflict both within the village and among villages. Perhaps more importantly, we find that the Bank’s effort to promote WUAs extended beyond their own project villages. The openness, consultative nature, and transparency found in the Bank WUAs are also found (albeit at a somewhat lower level) in the non-Bank WUA villages.  相似文献

Urban governance systems need to be adaptive to deal with emerging uncertainties and pressures, including those related to climate change. Realising adaptive urban governance systems requires attention to institutions, and in particular, processes of institutional innovation. Interestingly, understanding of how institutional innovation and change occurs remains a key conceptual weakness in urban climate change governance. This paper explores how institutional innovation in urban climate change governance can be conceptualised and analysed. We develop a heuristic involving three levels: (1) “visible” changes in institutional arrangements, (2) changes in underlying “rules-in-use”, and (3) the relationship to broader “governance dilemmas”. We then explore the utility of this heuristic through an exploratory case study of urban water governance in Santiago, Chile. The approach presented opens up novel possibilities for studying institutional innovation and evaluating changes in governance systems. The paper contributes to debates on innovation and its effects in urban governance, particularly under climate change.  相似文献

There is increasing international pressure to ensure that mining development is aligned with local and national development objectives. In South Africa, legislation requires mining companies to produce Social and Labour Plans, which are aimed at addressing local developmental concerns. Against the background of the new mining legislation in South Africa, this paper evaluates attempts to address mine downscaling in the Free State Goldfields over the past two decades. The analysis shows that despite an improved legislative environment, the outcomes in respect of integrated planning are disappointing, owing mainly to a lack of trust and government incapacity to enact the new legislation. It is argued that legislative changes and a national response in respect of mine downscaling are required.  相似文献

There is a considerable debate on the effects of environmental regulation on competitive performance. Based on survey data, this paper analyzesthe two main research questions, derived from literature, on the links between environmental regulation and competitiveness, by focusing on firms operating in the building and construction sector, i.e.: 1) whether environmental policy stringency affects the competitive performance of firms in the building and construction sector 2) and how a specific form of environmental regulation (direct regulation, economic instruments and soft instruments) affects this performance? By applying a regression analysis, we find that a more stringent environmental regulation, measured by inspection frequency, provides a positive impulse for increasing investments in advanced technological equipment and innovative products and on business performance. Moreover, a well-designed “direct regulation” appears to be the most effective policy instrument for prompting the positive impact of environmental policies on innovation and intangible performance while economic instruments do negatively affect business performance.  相似文献

National surveys and a survey conducted by the authors in March and April 2004 revealed that the public’s concerns about air, water and land pollution have declined during the last four years in the United States and more specifically in the State of New Jersey. In New Jersey pollution remains a major concern of most residents, even during a period of a war, anxiety about terrorism and the economy. Those most anxious about pollution do not believe that government is doing enough to protect the environment, want to maintain current environmental laws, and are worried about the future. Disproportionately they are African and White Americans, middle income, and college graduates, in other words, part of the American mainstream. Direct attempts to weaken environmental protection are likely to be resisted by this core of the population, which does not trust current federal, state and local governments to protect the environment. We expect concerns for the environment to continue and yet change as production processes in the United States continue a trend toward pollution prevention, and we wait for the public’s mental models to catch up with this evolving reality.  相似文献
