The Smart Square project has initiated and developed the first standardization document of its kind at the European level, defining procedures for conducting audits based on the Smart Readiness Indicator (SRI) of buildings.

The SRI assesses a building’s ability to use information and communication technologies and electronic systems to adapt its operation to the needs of occupants and the electricity grid, while improving energy efficiency and overall operational performance.
As buildings play a key role in energy consumption and achieving sustainability goals, this document marks a turning point in the process of evaluating “smartness” in the EU’s building stock. Developed in line with CEN/CENELEC guidelines, the CEN/CENELEC Workshop Agreement (CWA) 18193:2025 provides a structured methodology that ensures comparability, transparency, and consistency in assessing the smart functionalities of buildings.

The standard targets auditors, designers, specialists, and policymakers and covers key areas such as:

• building automation;
• energy efficiency;
• interaction with the electricity grid.

The document aims to support the harmonization of SRI assessment processes in the context of the digital and energy transition, while facilitating the integration of smart technologies into buildings.

In addition to the standardized methodology, the Smart Square project also introduces an online training platform  designed for all professionals interested in learning the principles of SRI assessment and applying them in practice. The platform is interactive, user-friendly, and offers a comprehensive overview of the SRI audit process.

With the publication of CWA 18193:2025, Smart Square takes an important step toward creating unified standards for smart buildings and enabling their effective integration into the future of sustainable construction in Europe.
