This report was published as part of the JustReno project, which strengthens the capacity of policymakers and municipalities in Hungary, Poland, and Romania to implement EU building renovation policies. It helps to identify worst-performing buildings, supports financial planning for energy renovations, and promotes cooperation between local and national governance levels. Find out more about JustReno.

Poland’s housing sector plays a pivotal role in achieving national climate targets and ensuring energy security. This report provides a comprehensive overview of the country’s residential building stock, the governance of building data, including the policy and legislative context, and the social context shaping housing and renovation needs. It sheds light on the complex relationship between energy performance, housing affordability, and the quality of data underpinning effective policy action.

Most Polish dwellings are located in urban areas, with significant variations in energy performance depending on construction year, heating and ventilation systems, and building materials. Older buildings tend to perform worst, while the lack of accurate, detailed and accessible data remains a major barrier to gaining an accurate picture of the building stock. Data gaps, coupled with limited digitisation and inconsistent coordination between national and local authorities, hinder effective renovation planning and implementation.

To strengthen the foundation for fair and efficient renovation, the report highlights key priorities for Poland:

• Improve the accuracy, quality and accessibility of open-source building stock data.
• Increase the degree of digitisation and automation of housing information systems, combining existing databases into a single system.
• Enhance coordination between national and local authorities in managing building data.
• Refine definitions of vulnerability, energy poverty and worst-performing buildings to support better-targeted policy responses.

Reliable data and integrated governance are essential for transforming Poland’s housing sector into a driver of energy efficiency, affordability and social resilience.
