Assessing the gap between a normative and a reality-based model of building LCA

Didier Albert Simon Vuarnoz, Thomas Bernard Paul Jusselme, Endrit Hoxha, Stefano Cozza

Recognized as a powerful methodology for the evaluation of environmental burdens, life cycle assessment (LCA) must be performed with close-to-reality inputs to be robust and accurate. However, the necessary real-world data is hardly available at the design ...

Do energy performance certificates allow reliable predictions of actual energy consumption and savings? Learning from the Swiss national database

Jean-Louis Scartezzini, Stefano Cozza, Arno Schlueter

The thermal performance gap in buildings is defined as the difference between the theoretical and the actual energy consumption for heating, and is known to undermine energy retrofit strategies and policies. This study examines the performance gap in retro ...

Usability assessment of building performance simulation tools: a pilot study

Marilyne Andersen, Thomas Bernard Paul Jusselme, Stefano Cozza

Due to climate change, the built environment is facing increasingly strict environmental targets. Thus, architects are challenged to design evermore high-performing buildings, a task for which they can no longer depend solely on their experience and intuit ...

Integrating hourly life-cycle energy and carbon emissions of energy supply in buildings

Didier Albert Simon Vuarnoz, Thomas Bernard Paul Jusselme, Stefano Cozza, Philippe Couty

Huge amount of energy resources greenhouse gas (GHG) emissions is devoted to the built environment. Therefore, an accurate assessment method of these indicators is compulsory. To take advantage of the temporal variation in the primary energy use and associ ...

Towards a pre-design method for low carbon architectural strategies

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

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

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

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 ...
