- Description
- The theme of the city is central to the concern of this paper, which argues that urban design is integral to the practice of architecture. While more and more of the earth submits to urbanization, we are confronted with a virtually inexhaustible source of new urban design problems and potential investigations. Among the most significant environmental challenges of our time are now the increasing fossil-fuel dependency of cities and buildings and their growing demand for energy – likely to be a major challenge for urbanism in the 21st century. In this context, avoiding mistakes in urban design at early stages could genuinely lead to more sustainable cities and less greenhouse gas emissions. This paper presents new research in the area of Green Urbanism in form of two models for sustainability of urban growth and green neighbourhoods, as cities need to transform from a fossil-fuel based model to a model based on renewable energy sources. It addresses the question of how we can best and cohesively integrate all aspects of energy systems, transport systems, waste and water management, passive and active strategies, natural ventilation and so on, into contemporary urban design, improving the environmental performance of our cities. The author provides a context for the discourse about the regeneration of the city centre via two case studies, a step-by-step transformation to sustainable models, and discusses how urbanism is affected (and can be expected to be even more affected in future) by the paradigms of ecology and the need to de-carbonise the energy supply. Two recent and relevant examples for the application of such urban design principles are the proposals for the Australian city of Newcastle: the ‘City Campus’ and ‘Port City’ projects. These concrete and realistic case studies give the paper a specific focus and illustrate, that it is less environmentally damaging to stimulate growth within the established city centre rather than sprawling into formerly un-built greenfield areas. Conclusion: Low-density has been for too long a principal contributor to carbon emission, while compact development fosters less driving.
