Study and work in London Brownfields require an understanding of the importance of these areas in two complementary contexts: history and metropolitan. History for revealing the logic and dynamics of these areas over time and Metropolitan as a way to understand the potentiality undeveloped or obsolete of these areas in the current scenario.
As the graph shows, the Greater London increases population growth at Industrial Revolution, which causes a reduction in the supply of land for urban expansion and densification of urban areas. Currently, the area available in the Brownfields is acquiring importance as reserve areas, avoiding saturate urban space and ensuring multiple possibilities for the future.
The significant growth of the urban environment in the current transition phase, not yet developed social, economic and environmental systems suitable to meet their needs. Energy systems, transport, housing, etc., which are still treated with the industrial logic, must undergo a paradigm shift in the structure of urban/metropolitan space. It is noteworthy that Energy is the capacity of a physical system to perform work. Energy exists in several forms such as heat, kinetic or mechanical energy, light, potential energy, electrical, or other forms.
With the formation of this metropolis, the Brownfields should serve as a core of dynamic transformation of the urban environment, through the spread of new forms of processing power and occupy the territory, considering the enhancement of the voids without, necessarily, building in these areas.
The strategic distribution of the structures in the territory and the unique feature of energy supplier for the construction of the city, the gasometers were chosen as study areas in the implementation of new social, economic and environmental systems. With the reactivation of these areas, intended to establish new metabolisms that focus on quality and efficiency of consumption and generation of energy necessary for urban development. In the 200 years that the UK has been using gaspower, the country has got used to the distinctive sight of gasometers. In the scenario that formed were landscape transformation vectors: the city has developed around these structures stored and supplied power to the new industrial activities. By replacing this energy source, the structures remained unused. Currently the gasometers are undergoing a process of re-signification; it will still be recognized as an object that provides power to the city, but now in a cyclic process comprising both the energy itself as it adds in the same economic and social elements.
The gasometers are scattered throughout the city, in a residential area of low density, high density, mixed areas, central areas with plenty of infrastructure, peripheral areas with deficient infrastructure and many other urban settings. Each area has a potential and need, according to urban training around you and the gasometer will be presented as the core development of the few activities in each region.
The central idea is that changing the logic of development of Brownfields, initiated by the gasworks, to move across the city, forming a contribution network, in which the end – activities should not be developed in the very gasometers, but around them. The gas holders are used as energy dissipation, while the Brownfields will be the director receptor, as represented by So the purpose of this paper is to indicate a range of possible programs that can be applied in understanding the potential of each gasometer area. These programs are divided into three categories: economic, social and environment and its main feature being support providers for more complex’s activities. As shown in figures, simulations were made to four different urbans situations, which led us to four differents scenarios: health, education, work and leisure. These scenarios have in common the issue of management and production of energy. Thus, the repetition is recommended in all these gasometers.
As a case study a deployment simulation was made on the Gasometer Bethnal Green which the methodology used was to recognize the action of rays of each of the activities: housing, energy, leisure, water, labor, metabolism and soil.
Thus, it was comprehensiveness areas defined for each activity should guide interventions in the urban setting.
Housing: densification on the coverage of an existing building, the elevation of the existing building and the addition of floors, readjustment for the construction of housing of use designed for other uses, empty of rebuilding and adding new elements in existing buildings.
Energy: capturing solar energy that must be generated to suppress the new demand will come as the result of the restructuring of the gasometer.
Leisure: contribute to the improvement of existing networks of leisure, such as park and bike paths.
