“…The set of results previously reported confirms the difficulty of an effective renewables policy in cities and, by extension, the inadequacy of planning tools for the urban development of RES that are focused solely on each single form of energy. Those kinds of tools, as discussed in Oludunsin et al [95] for biomass, in La Gennusa et al [96] for solar energy, in Ishugah et al [97] for wind energy, in Tkáč and Vranayová [98] for small-scale water energy systems, or for other RES technologies, are considered meaningful for assessing the potential of a specific renewable source, but their territorial outcomes are not consciously understood. In fact, urban energy planning requires integrated scenarios quite difficult to foresee: according to literature, this category of tools can be helpful but needs to be integrated in an all-encompassing way, through the combined use of planning methods and a higher-level governance system.…”

In the past, national energy planning guided the development of a central program for infrastructure investment over a defined time period. However, in the current geopolitical context, environmental damage, fossil fuel depletion, and territorial imbalance caused by the centralised energy model are all factors that require a change of energy structure, establishing actions to invest in energy diversification, and solid commitment to local renewable energies. This also implies an enhancement of the role played by local bodies, and particularly by municipalities, in achieving the targets of the Kyoto Protocol and now of the Paris Agreement, because renewable sources need to be studied, applied, and exploited at the local scale. Within this framework, this paper is organized as an overview on the promotion and implementation of the major RES technologies in the deployment of the new energy paradigm at the urban scale, taking into account multiple targets. A survey of existing literature underlines how the RES topic is mostly approached as a problem of energy supply and implementation of technology, but actual sustainability in terms of a social development process and improvement of quality of life by residents is often neglected. Then, this overview stimulated the authors to highlight three main critical issues and gaps and support the need of an all-encompassing approach as a final recommendation for a general RES urban planning advancement.

“…This correction factor is smaller than 1 (La Gennusa et al, 2011), and therefore, not taking it into account overestimates the effect of the shadow, and the irradiation received by the panels, in other words, the energy generated. Over the year this correction is secondary, because it is non-zero only in the early hours of the day and in the evening, especially in the winter when the PV panels produce just a small fraction of the total annual electricity.…”

“…The energetic producibility of RES plants, and the convenience to integrate solar energy panels in urban contexts with high building density, must be evaluated taking into account: (i) the typology, slope, aspect, and useful surface of the roofs [13,17,35]; (ii) the theoretical energy production of solar panels; (iii) the economic analysis (i.e., the payback time) according to the real energetic needs of users (e.g., single apartments, condominiums, and blocks) [19]. Firstly, it is necessary to analyze the roofs typology based on morphology and building materials.…”

“…Further models provide issues related to orientation and shape of solar energy panels [16,17] in order to maximize the production of solar energy [18]. Cellura et al [19] evaluated the relationship between the surface of the rooftops and the height of the buildings, providing a first tool to analyze the influence of the density of the built environment on the availability of solar energy.…”

Abstract:Energy planning has become one of the most powerful tools for urban planning even if several constraints, (i.e., aesthetic, archaeological, landscape) and technological (low diffusion of Renewable Energy Sources, RES) reduce its spreading. An efficient and sustainable urban planning process should be based on detailed energy issues, such as: (i) the effective energetic characteristics and needs of the area like urban density and energy consumption, (ii) the integration of different RES and (iii) the diffusion of high efficiency technologies for energy production like cogeneration and district heating. The above-mentioned energetic issues and constraints must be constantly updated, in order to evaluate the consequences on environment and landscape due to new distributed generation technologies. Moreover, energy strategies and policies must be adapted to the actual evolution of the area. In this paper the authors present a Geographical Information Database System (GIS DB) based on: (i) the availability of land use (Land Capability Classification, LCC) to evaluate the productive potential; (ii) the estimation of residential energy consumptions (e.g., electricity), (iii) the integration of RES. The GIS DB model has been experimented in a wide area of Central Italy, considering exclusively the solar energy source for energy generation. OPEN ACCESSSustainability 2014, 6 5731
