Nowadays, greenhouse gas (GHG) emissions continue to increase with the consequent climate changes. In urban contexts, the use of energy in buildings is one of the main causes of GHG emissions. The reduction of energy-use in buildings could be one of the main drivers to improve the
sustainability, liveability and quality of urban environment, together with the production of energy from the available renewable sources. To achieve energy sustainability in the most critical high-density urban contexts, it is necessary to optimize: the energy consumptions compatibility of different
users; the distribution of heat, for example through the district heating (DH) network; the use of all urban spaces, such as building envelopes and urban surfaces, to produce energy from the available renewable sources.
Smart Energy Solutions for Sustainable Cities and Policies.
The aim of this research is to drive a smarter use of energy, matching it with the available and more efficient energy sources on the territory to help policy makers in defining policies adapted to the real energy-use. Energy models at territorial scale can be applied to evaluate the impact of
climate change on the energy demand/supply of buildings; also the application to energy communities will be investigated. The goals are the optimization of energy models, the definition of a platform to harmonize territorial data and the design of a software tool useful to describe and quantify the energy consumptions.

Abstract: Today 54 % of the world's population resides in urban areas and in 2050 the projections are for 66 %. Therefore, the issue of city sustainability becomes increasingly important. This paper analyzes city energy sustainability with consideration to the complex built environment, high population densities, anthropogenic activities, energy demands, environmental impacts, as well as limits on both space availability and renewable energy sources. The evaluation considers models of thermal energy consumption for both residential and non-residential buildings based on a GIS tool. The thermal energy-use models consider established statistical methods as well as the introduction of energy-dependent urban-scale variables.

Abstract: Nowadays, resilience is a necessary component for a sustainable development of cities. Achieving increased resilience requires improved risk assessment and modeling, better planning and design, increased communication and collaboration. The aim of this study is to propose a flexible
methodology in order to analyse the energy sustainability and the risks of the metropolitan cities, in this case the method has been applied to the City of Turin. The main objectives are to evaluate the characteristics of the existing energy systems, their impact on sustainability and to understand how to satisfy the high-energy demand in a critical urban environment with few available renewable energy sources. This work describes a methodology to
identifying energy risks, vulnerabilities and resilience for residential and tertiary buildings in Turin. Three indicators to evaluate the energy resilience and security assessment were used. In particular, the assessment of impact of individual indicators was conducted by using the aggregation and weighting method. To improve energy resilience, two future scenarios were assumed: the expansion of the existing district heating and the exploitation of roof-integrated solar-thermal collectors. The first results on historical trend show that the annual thermal energy consumption depends on climate data but also on per capita earning, with an annual decrease of 3% after 2007. A similar trend can be observed in natural gas
consumption, in fact every year, natural gas decreases by 3%, while the district heating network increases by 8%. The results of future scenarios show an improvement of energy resilience, with a reduction of greenhouse gas emissions up to 12% with district heating expansion and 39% with also
the use of solar collectors.
