URBAN SYSTEMS AND ENERGY CONSUMPTIONS: A CRITICAL APPROACH
City transformations are also due to the development of new energy sources, which have influenced economy and lifestyles, as well as the physical and functional organization of urban systems. Cities are the key place where it is need to act for the achievement of strategic environmental objectives, such as reducing greenhouse gas emissions and energy saving. The hard resolution of these challenges depends on several factors: their multidimensional nature, the change of the economic and settlement development model, and also the complexity of the relationships between the elements that constitute the urban systems and that affect energy consumption. According to this awareness the Project Smart Energy Master for the energy management of territory financed by PON 04A2_00120 R & C Axis II, from 2012 to 2015 has been developed: it is aimed at supporting local authorities in the development of strategies for the reduction of energy consumption through actions designed to change behavior (in terms of use and energy consumption) and to improve the energy efficiency of equipment and infrastructure. With the goal of describing some of the results of the methodological phase of this project, this paper proposes a review of the major studies on the issue of energy consumption at the urban scale in the first section; in the second section the outcomes of the first phase of the development of the comprehension/interpretive model related to the identification of the set of physical/environmental variables at urban scale, that most affect the energy consumption, are described; the third makes a critical review of the reference scientific literature, characterised by a too sectoral approach, compared to the complexity of the topic.

The adequacy of main indicators used by the SEAPs is critically analysed MuSIASEM approach and the fund-flow model are proposed to develop indicators Energy modelling of the isolated buildings and the surroundings is developed to calculate the thermal energy demand at multilevel scale (building-district-city). Process for defining use and scope of indicators is proposed for European cities Results of use case showed their suitability in decision making in urban planning ABSTRACT The main instrument used to implement the EU 2020 objectives at local level is the Covenant of Mayors, which fosters the development of Sustainable Energy Action Plans (SEAPs); these plans aim to reduce CO2 emissions by at least 20% by 2020. These action plans are linked to different municipal promotion tools, and a set of indicators has also been proposed to define and monitor the actions. In general, the adequacy of the main indicators used by the SEAPs is analysed, taking into consideration the representation of the urban system across all scales (city, neighbourhood and building) as well as whether the chosen indicators enable the analyst to consider the influence of human activities (i.e. hours of use) on energy consumption, within the system. In contrast, this paper proposes to apply the fund-flow model as an accounting framework that can be used to develop indicators for energy-efficient urban planning. The energy model behind these indicators was obtained using an innovative procedure for energy simulation which considers the isolated characteristics of the buildings (type of construction, occupation, interior comfort, type of energy system) as well as the interaction with the surrounding buildings (shadows, streets, geometry).The indicators proposed have been developed within the SEMANCO UE project, and we have taken into account their potential as criteria for identifying the most effective actions for energy planning on multilevel scales. An example in Manresa (Spain) is used to test the usability. Our results demonstrate that these indicators are suitable for use in decision-making processes in the field of urban planning and for performing coherent comparisons of actions between urban areas, cities, countries or regions.
A conceptual framework for energy planning and CO2 emmissions counting in urban areas
The planning of energy supply systems for buildings in urban areas is a key-element in the reduction of energy consumption and greenhouse-gases (GHG) emissions. However, it also represents an increasingly complex task notably due to the emergence of new energy conversion technologies. The use of a framework based on a diagram representation of energy flows from the sources to the final consumption is a useful tool for energy planning endeavours, since it allows clarifying the analysis of improvement potentials along the energy chain. Swiss municipalities are deeply involved in sustainable energy solutions deployment and widely use energy planning methods to achieve their goal. Since they have at their disposal several financing instruments related to GHG or green electricity permits trading schemes for their energy projects, it is essential to perform an accurate accounting of GHG emissions in a specific urban area. The influence of using such trading schemes in urban energy project...

`Energy auditing’ as a technique for obtaining a ‘snapshot’ of the energy flows in a city or urban conurbation is discussed in the context of meeting national and international targets for CO2 emissions abatement. An audit methodology is presented which addresses the key questions: Who needs to be involved in the audit? How should the city or conurbation be divided? What data are required? How might these data be obtained and then analysed? Which are the areas of significant consumption? A basis for setting local targets for reducing future energy consumption and CO2 emissions is presented. The scope for auditing major cities and conurbations in the United Kingdom is identified with reference to implementing Local Agenda 21 and satisfying CO2 emissions reduction targets.
Urban policies and sustainable energy management

"This paper describes the results of the first year of the SoURCE – Sustainable Urban Cells – research project. The project’s main objective, focused on sustainable management of urban areas from an interdisciplinary and holistic approach, is to experience the sustainable reshaping of the city considering a minimum core of the larger city’s model, conventionally called the urban cell. The methodological approach aims to evaluate and improve the energy flows from nature to city, from city to itself and from city to nature. The method seeks to provide a standard procedure to evaluate the performance and optimization of the urban cell energy balance through innovation technology either with the use of renewable resources or in the final consumptions. The methodology was tested in a case study of a single urban cell. Since any urban cell will have a different energy balance due to local characteristics and functions, an urban cell can be added to a close one (generating a urban cells grid) in order to ensure a better energy balance from the addition of more than one urban cell. The project foresees the elaboration of tools and strategies for citizen information, training them about energy sustainability, with special emphasis on young people."

Energy Use in Cities "The book provides a unique knowledge resource for researchers, practitioners and decision-makers alike. It is based on a detailed and novel methodology to interrogate the socio-spatial features of energy demand across regions and cities, opening the path for ambitious measures to transform our relationship with energy and infrastructure in response to the global climate challenge."
Energy indicator in sustainable urban energy metabolism and challenges
Proceedings of the Institution of Civil Engineers - Energy
Urban areas, especially cities having a significant amount of materials and energy consumption, contribute to environmental degradation. Urbanisation and the development of cities is key to building sustainable societies. Urban metabolism studies can provide a remarkable accumulation of data and observations regarding the material and energy flows of cities. Energy metabolism studies can act as a means to understand better and, subsequently, make smarter decisions for sustainable development in cities. A multidimensional approach for urban energy systems can help to analyse how urban areas function regarding energy use and the underlying physical infrastructures. The present study aims to propose an energy indicators-based approach to performing energy analysis using a metabolic network perspective, within the urban energy system. The strategies presented here would be of interest to municipalities, urban planners, urban managers, policy makers and researchers to help them work more effectively to solve the complex challenges of developing healthy and sustainable cities. 26 Energy Volume 171 Issue EN1 Energy indicator in sustainable urban energy metabolism and challenges Ziebell and Singh
