Towards a pre-design method for low carbon architectural strategies

Emmanuel Rey, Marilyne Andersen, Thomas Bernard Paul Jusselme, Arianna Brambilla, Endrit Hoxha, Stefano Cozza

To face climate change, Switzerland proposes the 2050 energy strategy by fixing greenhouse gas (GHG) emission targets for the built environment. Designers will then have to increase operating performances while inimizing embodied impacts. This represents a ...

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 ...

Introduction of a dynamic interpretation of building LCA results: the case of the smart living (lab) building in Fribourg, Switzerland

Emmanuel Rey, Marilyne Andersen, Thomas Bernard Paul Jusselme, Endrit Hoxha

Although a building lifetime is not predictable, it is an essential data in the yearly impact calculation. Yet, in the assessment of the environmental impacts of building the lifetime is considered as a fixed value. The purpose of this study is to introduc ...

A Multi-Criteria Decision-Support Workflow for Early-Stage Neighborhood Design based on Predicted Solar Performance

Emmanuel Rey, Marilyne Andersen, Émilie Nault

Despite recent developments, the need for adequate guidance and support in the early decision-making process of urban planners, designers, and architects has recurrently been recognized. Traditional performance assessment methods, which are often based on ...

Studying the Dynamic Relationship between Energy Supply Carbon Content and Building Energy Demand

Emmanuel Rey, Marilyne Andersen, Thomas Bernard Paul Jusselme, Stefano Cozza, Didier Albert Simon Vuarnoz

Due to different temporal combinations of energy generation processes, the global warming potential (GWP) of energy supply evolves constantly. Despite this, the greenhouse gas (GHG) emissions related to the energy consumption in buildings are commonly asse ...

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 ...
