This article briefly presents the H2020 SUREFIT project’s innovative solutions developed to improve residential buildings energy conservation measures and indoor air quality through retrofitting, aiming for near-zero energy buildings.

A sustainable society is one that protects the environment while fostering conditions that promote the mental and physical well-being of all its members. In the building sector, this means creating structures that are energy-efficient, low-emission and healthy and comfortable. But can health and comfort be ensured while still ensuring sustainable use of resources?

Europe’s renovation of building stock, facilitated by digitalisation and paradigm shifts, can ensure sustainability, efficiency, and equity within ecological planetary boundaries. Estonian digitalisation initiatives streamline renovation processes by improving data accuracy and supporting renovation planning and decision-making, thus accelerating energy-efficient upgrades and aligning building stock transformation with broader European sustainability goals.

Exploiting data through innovative services can significantly enhance the energy and environmental performance assessment of the building stock. Key factors for success include data availability, accessibility, and quality. Within the H2020 TIMEPAC project, emphasis has been placed on enhancing the usability, reliability, and enrichment of Energy Performance Certificate data to effectively support urban-scale energy analysis.
