Energy performance and occupancy-based analysis of visual and thermal comfort for transmittance level and layout variations of semi-transparent photovoltaics

Marilyne Andersen, Giuseppe Peronato, Giorgia Chinazzo, Jan Wienold

This paper investigates the impact of transmittance level and layout variations of semi-transparent photovoltaics (STPV) on both energy performance and occupancy-based visual and thermal comfort, simulating a reference office with a fully south-oriented gl ...

Urban planning support based on the photovoltaic potential of buildings: a multi-scenario ranking system

Giuseppe Peronato

An increased use of renewable energy and of energy efficiency measures in buildings is needed to face the urgency of climate change. Buildings are in fact among the highest worldwide consumers of primary energy, mostly of fossil fuel origin, while still ma ...

Assessment of the Building‐Integrated Photovoltaic potential in urban renewal processes in the Swiss context: Complementarity of urban‐ and architectural‐scale analyses

Emmanuel Rey, Marilyne Andersen, Giuseppe Peronato, Sergi Aguacil Moreno

This paper presents two different approaches to deal with the assessment of the BIPV potential in building renovation projects in urban areas, taking Neuchâtel as a representative middle‐size city of the Swiss plateau. 1) A building‐scale analysis aiming t ...

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

Emmanuel Rey, Marilyne Andersen, Giuseppe Peronato, Sergi Aguacil Moreno, 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 ...

A toolkit for multi-scale mapping of the solar energy-generation potential of buildings in urban environments under uncertainty

Emmanuel Rey, Marilyne Andersen, Parag Rastogi, Giuseppe Peronato

Many municipalities and public authorities have supported the creation of solar cadastres to map the solar energy-generation potential of existing buildings. Despite advancements in modelling solar potential, most of these tools provide simple evaluations ...

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

Emmanuel Rey, 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 ...

Integrating urban energy simulation in a parametric environment: a Grasshopper interface for CitySim

Emmanuel Rey, Marilyne Andersen, Jérôme Henri Kämpf, Giuseppe Peronato

The increasing popularity of parametric design tools goes hand in hand with the use of building performance simulation (BPS) tools from the early design phase. However, current methods require a significant computational time and a high number of parameter ...

Sensitivity of calculated solar irradiation to the level of detail: insights from the simulation of four sample buildings in urban areas

Emmanuel Rey, Marilyne Andersen, Stéphane Bonjour, Giuseppe Peronato, Jérémie Stoeckli

The assessment of the solar potential in urban areas relies on a geometrical model that can be defined at different levels of detail (LOD). In this work we compare the solar irradiation simulated on the surfaces of four sample buildings, which were modeled ...

Sampling of building surfaces towards an early assessment of BIPV potential in urban contexts

Emmanuel Rey, Marilyne Andersen, Giuseppe Peronato

Although the integration of PV systems in the building envelope (BIPV) is an important factor for the acceptability of such installations, current urban-scale solar potential metrics only partially consider this aspect. As part of the definition of BIPV-su ...

Review and critical analysis of early-design phase evaluation metrics for the solar potential of neighborhood designs

Emmanuel Rey, Marilyne Andersen, Émilie Nault, Giuseppe Peronato

The energy performance of a building is strongly influenced by its level of solar exposure, in turn affected by the climate, built context, and building morphological characteristics. Since these are typically fixed at the early- design phase, performance ...
