From researchers to local governments, the BSO web tool offers detailed, transparent, and up-to date information that can help users carry out activities, such as innovative research on emissions reduction, or drafting policies that improve the quality of buildings.
Below is a compilation of testimonies that demonstrate how researchers and policymakers are using the BSO to have a real-life impact on the lives of European citizens.
Testimonials
“The reliable and comparable data across EU countries is very helpful in our projects concerning policy design; it helps us to improve our policy recommendations and give an informed and targeted strategy for energy and building policies.I would not be able to receive a result of a similar quality, transparency and comparability by only using national data and it would take a lot more time and effort.”
Iska Brunzema- Research Associate at Fraunhofer Institute for Systems and Innovation Research (ISI), Germany
“For my research focusing on embedded emissions from building materials, the main highlight of the BSO are the data on building elements and materials. The BSO user interface makes data easily and readily available - a broad range of users can benefit from this.”
Meta Thurid Lotz -Fraunhofer Institute for Systems and Innovation Research (ISI), Germany

“Without the information that the BSO gives us, it is more difficult to understand how we position ourselves against others and to issue regulations that could improve the life of our citizens. It is the only platforms that combines data from so many sources and different countries in a comparable way”.
Pedro Pacheco Machado – Head of Facilities and Logistics Department at the European Southern University, Portugal
