“…This is a relevant factor to be considered in the optimization of urban surfaces (i.e. land, façades and roofs) to increase the overall energy efficiency of the district, produce energy from RES, and improve the outdoor thermal comfort in cities [15,16]. Aligned to this and compliant with the Energy Roadmap 2050 [17], a holistic approach would create win-win solutions by finding the best configurations to meet the European targets of sustainability for new and existing buildings and neighborhoods.…”

This study presents a holistic approach applied to assess the exploitation of renewable energy sources for design interventions in the early design phases in a consolidated urban environment. With reference to the cooling season, the approach implies set of environmental analyses focused on twofold assessments: (i) the use of renewable energies sources for active and passive strategies, (ii) the impact on outdoor thermal comfort of the technological solutions and cool materials installed on the buildings' facades. From the definition of the local boundary conditions, preliminary climate analyses were conducted with dynamic simulation tools such as Ladybug and DIVA-for-Rhino, while numerical and computational fluid dynamics models, such as ENVI-met and OpenFOAM, were used to carry out microclimate and wind flow analyses. The approach is tested on two existing residential building blocks in a case study district in Bolzano (Italy). The assessment of several design interventions and building technological solutions have been studied: from the (ii) addition of one story volume on the existing buildings, to the (ii) creation of new green areas, and the (iii) installation of building integrated photovoltaic (BIPV), vertical greenery and double skin façade (DSF) systems on the building's façades. The results, divided in practice and policy implications, demonstrate that preliminary analyses play a relevant role to assess the exploitation of renewable energy sources to optimize the use of urban and building surfaces since the early design phases. High-albedo materials on the façades can totally counterbalance the loss of solar potential due to the overshadowing effect of the additional story. The combination of cool materials (e.g., white reflective plaster) and the increment of the buildings' height could reduce about 1°C the thermal discomfort registered during the high thermal peak during the day. Solar and urban airflow analyses allow to optimize the integration of BIPV in a DSF system; while the installation of green façade can reduce the air temperature locally up to about 0.5°C.

“…In this context, Europe is also faced with the challenge of implementing growing amounts of intermittent power sources such as micro-solar and wind sources in the electricity grid. The generation of renewable energy is characterized by intermittency; therefore, it is imperative that a mix of sources should be selected and used along with the suitable energy storage mechanisms in order to best utilize the available renewable energy resources and ensure the continuity of supply [2].…”

Background: In recent years, there has been an increasing interest in using micro-renewable energy sources. However, planning has not yet developed methodological approaches (1) for spatially optimizing residential development according to the different renewable energy potentials and (2) for integrating objectives of optimized energy efficiency with other environmental requirements and concerns. This study addresses these topics by firstly presenting a new concept for the regional planning. Methods: The methodological approach for the evaluation of spatial variations in the available energy potential was based on the combination of existing methods adapted to the local scale and data availability. For assessing the bioenergy potential, a new method was developed. Other environmental criteria for deciding about sustainable locations were identified through a survey of more than 100 expert respondents. This survey involved pairwise comparisons of relevant factors, which were then translated into relative weights using the Analytical Hierarchy Process. Subsequently, these weights were applied to factor maps in a Geographical Information System using a weighted linear combination method.
