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.

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.
