Buildings belong to the most cost-effective sectors where carbon dioxide (CO2) reductions can be achieved, and urban regeneration offers a good intervention point for switching to sustainable fuel sources, as changes in energy infrastructure can be coupled with other construction, thus decreasing the cost. However, the potential energy savings that are feasible do not match the more ambitious policy targets. Based on case studies in the Netherlands, obstacles are identified in the context of urban renewal that need to be overcome if energy efficiency measures are to be implemented and space heating replaced with low-carbon technologies. The current free-market public policy instruments have not managed to address the obstacles identified in the case studies due to poor market signals, costs and payback periods, risks, and a lack of leadership on environmental targets and policies on sustainable urban renewal. The potential for stronger government intervention is examined for the effectiveness in reducing both energy consumption and CO2 generation. Legislation could produce a certain policy outcome in terms of CO2 reduction in urban renewal in the Netherlands if compliance and legitimacy are ensured, but policy consideration is also required to account for the dilemma of low-income households and the rebound effects associated with occupant behaviours. Les bâtiments appartiennent à l'un des secteurs les plus rentables où il est possible de réaliser des réductions de CO2 et où la rénovation urbaine permet de passer à des sources de combustibles durables, les modifications apportées aux infrastructures énergétiques pouvant être couplées avec d'autres constructions, ce qui en diminue le coût. Toutefois, les économies qu'il est possible de réaliser au niveau de l'énergie ne correspondent pas aux objectifs politiques plus ambitieux. Des études de cas menées aux Pays-Bas ont permis d'identifier, dans le contexte du renouveau urbain, des obstacles qu'il faut surmonter si l'on veut mettre en ?uvre des mesures d'efficacité énergétique et si l'on veut remplacer le mode actuel de chauffage des locaux par des technologies à faible dégagement de CO2. Jusqu'à présent, les instruments de la politique publique libérale n'ont pas permis de renverser ces obstacles pour les raisons suivantes: faibles signaux du marché, coûts et périodes de récupération, risques et manque de leadership en matière d'objectifs environnementaux et de politique concernant la rénovation urbaine durable. Cet article examine les possibilités d'un interventionnisme plus fort de la part des autorités pour améliorer la réduction à la fois de la consommation d'énergie et de la production de CO2. La législation pourrait produire quelques résultats en termes de réduction du CO2 dans la rénovation urbaine aux Pays-Bas si l'on garantit la compatibilité et la légitimité; mais il faut également prendre en considération les questions de politique et tenir compte de l'impasse que constituent les foyers à faibles revenus et les effets de rebond associés au comportement des occupants.

Using surveys collected from 10 major metropolitan cities across the world, this article examines the factors that affect the extent to which people feel connected to others who live in their neighborhood and feel proud and satisfied with life in their cities. The cities included in the analysis are: New York, London, Paris, Stockholm, Toronto, Milan, Berlin, Seoul, Beijing and Tokyo. We find that certain aspects of the built environment, the conditions of the public sphere, and the extent of positive social networks in the city are critically important for understanding residents’ connections to each other and to their cities. Our findings provide insights for policy makers and planners concerned with making cities viable and livable. 相似文献

China launched the policy of linking the increase in urban development land with the decrease in rural development land① in 2003. The paper focuses on two typical paths for implementation of the policy, i.e., exchanging homestead for urban housing, and "double exchanges." Based on a study on urbanization development, the paper analyzes the institutional innovation in the case of exchanging homestead for house in Huaming Town, as well as the jeopardization of "double exchanges," before summarizing the applicability of the "urban-rural land linking" policy. At the end, the paper emphasizes that in order to address the problems emerging during various kinds of urbanization, the linking policy should be carried out in accordance with local conditions and circumstances. 相似文献

Meeting the demand for independent living from the increasing number of older people presents a major challenge for society, government and the building industry. Older people's experience of disabling conditions can be affected by the design and layout of their accommodation. Adaptations and assistive technology (AT) are a major way of addressing this gap between functional capacity and the built environment. The degree of adaptability and the differences in the average cost of adaptation of different types of property are large and there is major variation within property type. Based on a series of user profiles, it was found that a comprehensive package of adaptations and AT is likely to result in significant economies arising from a reduction in the need for formal care services. This finding is sensitive to assumptions about how long an individual would use the adaptations and AT, as well as to the input of informal care and the nature of their accommodation. The present study, which focused on social housing, has implications for how practitioners specify ways of meeting individual needs as well as providing a case to support the substantial increase in demand for specialist adaptation work. 相似文献

2003年以来,我国推行了城乡建设用地增减挂钩的政策。本文重点研究了增减挂钩政策实施中两条典型的路径:宅基地换房和双置换,并基于城市化道路研究的角度指出了华明镇宅基地换房的制度创新和双置换的危害和教训,并进一步总结了增减挂钩政策的适用性。如何妥善解决千差万别的农民的城市化,需要通过因时而异、因地而异的方式来实现,当前一些地方在增减挂钩试点中一刀切的、不研究地方实际的城市化道路是断不可取的。 相似文献

Stefano Casciani 《Architectural Design》2007,77(3):26-33
At the start of the new millennium, Massimiliano Fuksas was one of the most significant Italian architects working outside his home country. His reputation in Italy and abroad, however, was taken to a further level by his completion of the New Milan Trade Fair. Stefano Casciani, an ex-student of Fuksas, provides an insightful and intriguing account of his ‘old’ professor: a robust and seemingly contradictory figure who is capable of great voluminous expression and delicacy. Casciani also finds constancy in his unrelenting energy, freshness and wit. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献
