The Technology Assessment group is part of the multi-disciplinary Laboratory for Energy systems Analysis (LEA) at the Paul Scherrer Institute (PSI) and is the continuation of the former GaBE Project. Technology Assessment incorporates a comprehensive range of research areas to achieve three main objectives:
- To improve understanding and thereby enable comparisons of current energy technologies and future energy options for the electricity, heating and transport sectors based on environmental, economic and socially relevant factors.
- To provide quantitative, systematic, and interdisciplinary assessments of energy technologies and energy supply strategies through the development and application of consistent methodological frameworks and databases.
- To support rational decision-making for sustainable development in the Swiss and international energy sectors, and to communicate balanced research findings to decision-makers and stakeholders.

Une promotion ciblée de l'innovation pour la transition énergétique
Comment les innovations naissent-elles et comment peuvent-elles être encouragées de façon ciblée en vue de la transition énergétique? Michael Weinold, chercheur au PSI, a tenté de répondre à cette question en prenant pour exemple les lampes LED.
Neutralité carbone: inclure les matières premières
Un nouveau modèle de calcul du PSI visualise les interactions complexes entre technologie, besoins en matières premières critiques et impacts environnementaux nécessaires à la transition du système énergétique vers «zéro émission nette» de gaz à effet de serre.
Decarbonizing Building Construction
The buildings we live and work in are changing – becoming smarter, more efficient, and powered by cleaner energy. But while we’ve made strides in reducing operational emissions, there’s a hidden carbon footprint that remains largely overlooked: the emissions locked into the materials themselves.
