Assessing visibility in multi-scale urban planning: A contribution to a method enhancing social acceptability of solar energy in cities

Jean-Louis Scartezzini, Christian Roecker, Maria Cristina Munari Probst, Josef Andreas Schuler, Pietro Florio

Urban areas are facing a growing deployment of solar photovoltaic and thermal technologies on building envelopes, both on roofs and on façades. An effective solar energy planning process considers social acceptance, in relation to the landscape alteration ...

3D model discretization in assessing urban solar potential: the effect of grid spacing on predicted solar irradiation

Marilyne Andersen, Giuseppe Peronato

The increasing interest in solar energy production in urban areas requires an accurate simulation of solar irradiation on building surfaces, including vertical surfaces. However, solar potential analyses are usually conducted on 2.5D models, which are limi ...

Definition of design scenarios for the arrangement of tilted solar arrays and estimation of their electricity production from horizontal irradiances

Adrien Legrain, Sylvain Vitali

The goal of this project is to assess the potential of PV tilted arrays on flat roofs. Multiple evaluations according to different performance indicators are compared to find the optimal potential of three roofs situated in the urban environment of Neuchat ...

Assessing the photovoltaic potential of flat roofs: Insights from the analysis of optimised array arrangements

Marilyne Andersen, Sergi Aguacil Moreno, Giuseppe Peronato, Adrien Legrain

PV installations on flat roofs offer a wide range of design options, which are usually neglected in urban-scale assessments as these typically assume horizontal or other fixed arrangements. In this study, we analyse the influence of common design parameter ...

Ternary semitransparent organic solar cells with a laminated top electrode

Frank Nüesch, Roland Hany, Jakob Heier, Lei Wang, Surendra Babu Anantharaman, Paolo Testa

Tinted and colour-neutral semitransparent organic photovoltaic elements are of interest for building-integrated applications in windows, on glass roofs or on facades. We demonstrate a semitransparent organic photovoltaic cell with a dry-laminated top elect ...

Does roof shape matter? Solar photovoltaic (PV) integration on building roofs

Jean-Louis Scartezzini, Dan Assouline, Nahid Mohajeri Pour Rayeni, Bérénice Guiboud

This paper focuses on roof-shape classification and solar potential for integrating photovoltaics (PV) on roofs. A machine-learning approach, Support Vector Machine (SVM), is used to classify the roof shapes in the city of Geneva. The impact of various roo ...
