Commission V, WG V/7 KEY WORDS: city as an organism, energy balance, metabolism, free energy, flows of resources, urban environment, entropy. ABSTRACT:Today, humanity is experiencing an "urban age", and therefore issues of good management of energy consumption and energy spent on utilization of waste in cities are becoming particularly acute. In this regard, the working group of the World Energy Council proposed a concept of the "energy balance" of the urban environment. This concept was that the energy produced should cover the energy consumed. Metabolism of the urban environment is so hot and so rarely studied by urban planners. This condition is linked first with the fact that metabolism is nothing more than a network of exchange of physical, energy resources and information. This is the real point of meeting the natural, technological, social, economic processes and their transformation into one another. Metabolism is the most important tool for knowing the real mechanics of the movement of resources in such a complex system as the urban environment. The content of the article is an analysis of significant energy and material flows characterizing the metabolism of the urban environment. We considered in the article a new energy paradigm. This paradigm will help in carrying out research in such areas as reducing the burden on the state of the environment, reducing environmental problems and reducing dependence on fossil fuels. Methods and models of metabolic processes in the urban environment will allow to implement in practice the concept of sustainable development of the urban environment, which is the development of the teaching V. Vernadsky about the noosphere.
The research aim is to obtain a cartographic model of an urbanized territory by means of thermal survey in an infrared range. With this cartographic model, it will be then possible to reduce the zones in the urbanized territories differing in the level of superficial heat. Further, we will be able to reduce the proof thermal anomalies and thermal structures of the localities that are related to the natural and anthropogenic systems. On the examples of the cities of Ukraine – Energodar and Nikopol, we defined the sources of caloradiances from major industrial concerns as well as from thermal and nuclear power plants. For comparison, we built the model of thermal structure of the city of Tokai and the nuclear power plant with the same name Tokai (Japan). The sources of caloradiances can be, for example, pipes of thermal power stations, ponds-coolers, corps of steel-making production, and other similar objects. If the sizes of such source are known, then we are able to get the absolute values of temperatures.
The urban environment is a networked metabolic organism. The urban environment includes networks that feed it with energy, resources, people, goods and information. The urban environment carries out a permanent transformation of matter, energy and produces waste, which together change the urban environment. We have proposed to use an indicator for assessing the efficiency of the metabolism of the urban environment, which allows to take into account the relationship between the urban structure, energy consumption, emissions of pollutants and the intensity of consumption of natural resources. We use this indicator as a tool for forecasting sustainable urban development. Using the example of Poltava city, we have shown that the indicator for assessing the metabolic efficiency of the urban environment can be used as one of the decision-making tools for the sustainable development of Ukrainian cities. The improvement of existing and development of new indicators is an important task towards the implementation of the concept of sustainable development, which is a logical continuation of the teachings of V. I. Vernadsky on the noosphere.
During transiting to the post-industrial era the role of cities and urban environment functions are transformed. A new type of economic system imposes new requirements to the urban environment as a space for the population life and doing business. Today, on the basis of the concept of sustainable development, a general scientific paradigm of cognition is being formed as a result of the synthesis of sciences about nature, society and man. There are many approaches to the concept of sustainable development. The most modern concept, according to the authors of the article, understands of sustainable development, which is based on laws of the conservation of energy or power, as a general law of Nature. The article proposes a comprehensive approach based on the integration of the capabilities of modern GIS and intelligent technologies for estimating the potential, real and missed opportunities of the urban environment in the context of using incomplete and fuzzy information. The application of the proposed approach to estimating the sustainable development of the urban environment on the example of Ukrainian cities is shown.
