The Entranze Observatory team welcomes enquiries from researchers, policy professionals, journalists and practitioners working on European building energy renovation.
For questions about our datasets, methodology or analytical approach, write to the research team. Response times are typically 3-5 working days. Custom data extractions for academic and policy research may be requested with a brief description of the intended use.
Journalists covering EU climate policy, building renovation or energy efficiency are welcome to request background briefings or quotes. We provide commentary grounded in our published data — no off-the-record statements on political positions.
The observatory collaborates with national research institutes, university departments, and European policy bodies. Collaboration proposals should include institutional affiliation, research scope and expected output format.
If you identify an error in a published dataset or calculation tool, please submit a correction request with a reference to the specific entry and the source supporting the correction. All validated corrections are logged in the dataset changelog.
General enquiries can be sent via the contact form. The observatory does not provide personalised energy audits or renovation quotes — for project-specific advice, consult a certified energy assessor in your member state.
