The EU-funded SMARTeeSTORY project has launched a new Smart Readiness Indicator (SRI) Calculation Web Tool to support the digital and energy transition of non-residential historic buildings across Europe.

Developed by TECNALIA and further enhanced in collaboration with RINA-C, the web-based tool enables building owners, energy experts and public authorities to assess how prepared historic buildings are to adopt smart technologies, while respecting heritage constraints.

Based on the European Commission’s official SRI framework (Method B – Expert SRI Assessment), the tool provides a guided and user-friendly interface for evaluating smart readiness. The latest version introduces advanced decision-support features, including target-setting based on energy, environmental or economic priorities, tailored suggestions for smart solutions, and a financial module offering high-level estimates of savings and cost-effectiveness.

The tool was tested and validated through three SMARTeeSTORY demonstrators in Riga (Latvia), Granada (Spain) and Delft (the Netherlands), all heritage-protected buildings. The assessments showed significant improvements in smart readiness, with post-intervention SRI scores reaching up to 83%, demonstrating that historic buildings can achieve high levels of smart readiness through carefully selected, non-invasive digital upgrades.

Designed for a wide range of stakeholders, from building owners and energy auditors to municipalities, designers and researchers, the SMARTeeSTORY SRI Web Tool supports informed decision-making and practical renovation planning. While tailored to historic buildings, it is also applicable to other building types, ensuring replicability and scalability across the European building stock.

The tool represents an important step towards improving energy performance, comfort and operational efficiency in Europe’s heritage buildings while preserving their cultural value.
