Abstract

Urban growth is connected to increasing demands of housing and working areas. A large proportion of the urban growth occurs at the urban fringe and urban hinterland. Urban growth in the form of sprawl can lead to a separation between workplace and housing thereby increasing the need of cars to commute. That in turn cause various environmental problems. In order to ameliorate this problem, the idea of the compact city has been presented. However, densification can imply a loss of other important urban quality factors of, such as green spaces. A reduction of urban green structure can lead to degradation of ecosystem services, such as storm water treatment, air quality, recreation and aesthetic. The aim of this study is to develop tools for enhancing the possibilities for win-win solutions in the development of urban environments. The study considers the function of urban form in sustainable development. The sustainable development concept considered is urban form as a tool for ecological planning. Here form and design are factors in damping of energy needs and water flux in the urban environment. The study sets principles for understanding the in-terconnection between urban form and energy needs, water treatments and travel patterns Thus the investigations show that urban form and design effects solar energy potential, ecologically sound treatment of storm water, and the means of travel. The study also considers the concept of sustainable development as enhancing urban quality of life. This part of the study focuses upon the functions of green space. An investigation was carried out on how and if the characteristics found in Swedish green space fulfil different typologies of green space. These green con-cepts are; sheltered patios, designed gardens, nature, public walks, green hiding-places for children and traffic-safe playing fields. Building upon these conceptions of urban green spaces the results of the research lay out a new order for analysis and designing urban green space. This reorganization of concepts acts as a toolbox for urban planning. These tools are purposed as a means for improved and enhanced dialogue between planners, building entrepreneurs and urban residents. It is suggested that green concepts should be used to create functional and inspiring environments for everyday use.
