FAQS
First steps
You will be required to follow a training plan on the e-learning platform and achieve at least level 2 of expertise. Then, you will receive login credentials via email.
It is highly recommended that you visit the building and its installations. Depending on the size of the building, the ideal contact point is the maintenance and operations manager. Access to inspection of the BMS (if present) is required, as is an understanding of the HVAC and other building installations and their control systems, according to the Smart Ready Service Catalogue.
Yes, it is possible and highly recommended to select the best options during the design phase to maximise the SRI score and have a positive impact on the three key functionalities:
(1) Energy performance and operation
(2) Response to the needs of the occupants and
(3) Flexibility for the grid, including demand response
Regulation
No, the Smart Readiness Indicator (SRI) remains voluntary across the European Union. However, this status is set to change in the near future for specific building categories.
Under the revised Energy Performance of Buildings Directive (EPBD) adopted in April 2024, the European Commission is mandated to:
By June 2026: Deliver a report on the testing and implementation of the SRI based on national test phases and other relevant projects
By June 2027: Adopt a delegated act requiring the application of the SRI to non-residential buildings with an effective rated output for heating, ventilation, and air-conditioning (HVAC) systems over 290 kW
This means that, starting from mid-2027, the SRI will become mandatory for large non-residential buildings exceeding the specified HVAC capacity.
By 30 June 2027, the European Commission shall adopt a delegated act requiring the application of the SRI to non-residential buildings with an effective rated output for heating systems, air-conditioning systems, combined space heating and ventilation systems, or combined air-conditioning and ventilation systems of over 290 kW.
Calculation methodology
The level of functionality of a building service (i.e. 0, 1, 2, 3 or 4) directly impacts the final SRI score. Each level corresponds to a different 'smartness' value, contributing to the overall score in the three key impact areas of the SRI:
(1) Energy performance and operation
(2) Response to the needs of the occupants and
(3) Flexibility for the grid, including demand response
It is not predetermined which method should be used in which cases. However, Method A, the simplified one, is generally suited for small buildings with low complexity and lower energy consumption, while Method B is intended for larger buildings with higher energy use and more complex technical systems.
Methods A and B are not interchangeable, as Method A uses a simplified list of 27 smart services, whereas Method B relies on the full list of 54 services.
Although the Energy Performance Certificate (EPC) label/class does not affect the SRI score, it is still considered relevant information given that SRI certification is likely to be integrated into EPCs. Additionally, the weighting factors could be customised according to EPC results, with appropriate weighting according to the actual relevance of EPBD services (e.g. heating, cooling, DHW and lighting energy demands).
The effective rated output of HVAC systems does not affect the SRI score. However, if SRI certification were to become mandatory for Member States, the obligation would initially apply to all non-residential buildings with an equivalent rated capacity greater than 290 kW.
If a technical domain is deselected, this means that it is not present in the building and will not be assessed. Therefore, it will not impact the final SRI score negatively or positively. However, some technical domains may be mandatory for assessment due to strategic decisions or mandatory requirements for buildings by Regulation at Member State level (e.g. heating in cold climates).
Each Member State can customize the service catalogues that determine the scoring weights, or adopt the default values provided by the SRI support team. For further details on the calculation please refer to the Final report on the technical support to the development of a smart readiness indicator for buildings available at https://op.europa.eu/s/z5pb
Yes, the methodology will evolve. Feedback and lessons learned from the test phases will inform the national transposition process and future updates.
On the last page of each service's support sheets, there is a table showing the service's impact score. This table gives the number of points awarded to each functionality level of the service in question by impact criterion.
The “ordinal impact scores” table on the “Results” page therefore represents the sum of the points associated with the functionality levels selected for each service in a technical domain by impact criterion. If certain services are not applicable, their points are not included in this sum. If several functionality levels are associated with the same service, the number of points for the service is calculated based on the percentage of application of each functionality level.
The “Maximum possible ordinal impact scores” table on the “Results” page represents the sum of the points associated with the maximum functionality levels for all services in a technical domain by impact criterion.
Oui, le SRI offre la possibilité d'évaluer des parties de bâtiments (comme certains étages de bâtiments tertiaires) ou des logements seuls dans des immeubles résidentiels collectifs. Par contre, cela necessite souvent l'évaluation de certains systèmes techniques à l'échelle du bâtiment entier (comme des générateurs des systèmes CVC, production et stockage locale d'énergie et autres).
Si un bâtiment ne possede pas de parking exterieur ou intérieur, le domaine "Recharge des véhicules électriques" ne doit pas être évalué.

Many of the SRI services are sourced from EN 15232 “Energy Performance of Buildings — Impact of Building Automation, Controls and Building Management” (module M10) which is the previous version of the ISO 52120-1 standard “Energy performance of buildings – Contribution of building automation, controls and building management – Part 1: General framework and procedures”. This standard is the overarching standard that models the impact of BACS on a building’s energy consumption. The EN 15232 standard has been developed by CEN/TC 247 as part of a series of standards aimed at harmonising of the methodology for the assessment of the energy performance of buildings, called as the “EPB set of standards”.
No, the SRI classes don't match those of the ISO 52120 standard, although their requirements are closer. The ISO 52120 standard actually defines four classes of building automation systems:
- Class A: High energy performance building automation and control systems (BACS) and technical building management (TBM)
- Class B: Advanced BACS and TBM
- Class C: Standard BACS
- Class D: Non-energy efficient BACS
While the SRI methodology procures seven SRI classes (A–G).
Triage
No, the nine technical domains of the Smart Readiness Indicator (SRI) are not necessarily applicable to all building projects. Their applicability depends on the specific characteristics and technical systems present in each building.
The SRI methodology is designed to be flexible and modular.
Only domains relevant to a particular building are considered in the SRI calculation.
The final SRI score is calculated based only on the relevant and applicable domains, and the weighting is adjusted accordingly.
Input forms
Selecting 'Not applicable' means that the service will not be assessed. This means that the methodology will not assign the maximum score to the reference building. Therefore, the service will not penalise the final score for the absence of the service in the building. This option can be selected when the service is not present and the methodology and/or national regulations allow it. The application includes a message to guide users on the use of this option when they move the mouse over each service description.
If a service is covered by more than one functionality level (i.e. a different level of automation), you can use the 'percentage box' to indicate the percentage of floor area covered by each level. When a number lower than 100% is entered, a new line will automatically appear including the remaining percentage. This functionality can be used as many times as needed, not just twice. The calculation methodology will then take these different functionality levels into account to sum the ordinal scores and proceed with the final weighting accordingly.
Each service is accompanied by a '+' button that opens a window in which a description can be entered detailing how a specific level of functionality is covered by the technical building systems present in the building or building unit assessed. This window allows text, as well as images or pictures of systems or layouts, to be introduced.
This section serves two purposes: firstly, it allows the SRI auditor to take notes and, secondly, it provides a proper justification that contributes to the quality check mechanism at member state level.
Clicking on the button associated with each service will automatically open the dedicated factsheet.
This factsheet provides the relevant information needed to understand the different functionality levels associated with the service and its corresponding impact scores.
It is not always possible to select 'Not applicable' because there is a list of services that must always be assessed. This decision can be made by the Member State, but in the meantime, the SRI2MARKET application uses the same approach as the default methodology developed by the SRI Support Team at EU level.
You will find a plus symbol (+) on the right side of each question in your project. Click this to open a window where you can upload justifications, comments and photographs.
These photographs or images may be required for justifications and quality checks at country level. Although this is not yet mandatory, it is recommended, especially when justifying functionality levels could be difficult. The accepted file formats are JPG, PNG and PDF.
The number of functionality levels for one smart-ready service is limited only by the maximum number of levels for smart-ready services, which is five: levels 0, 1, 2, 3 and 4. An additional 'Not applicable' option is available for some services.
Quick exploration
The “Quick Exploration” feature provides the ability to quickly select and explore two upgrade options, individually designed for each base case. The upgrade options consist of a medium and a high-level upgrade option.
The results are based on an extensive literature review and the results were reviewed by experts.
The difference you're seeing is normal. The 'Quick exploration' provides a general estimate based on standard use-cases developed through expert analysis and extensive research. These are tailored for typical building types and locations. However, every building is unique, and your actual SRI score may vary due to specific characteristics or conditions. For a deeper understanding, we recommend exploring the e-learning platform or consulting a certified EPC-auditor.
You can find more in-depth information in the underlying data sheet, which is available on the e-learning platform.
The "Quick exploration" tool allows users to quickly select a building most similar to their own from the 225 use cases and view the approximate current SRI score of their building, as well as explore individual upgrade suggestions.

General Questions
A high SRI score means that a building is well-equipped with smart technologies that enhance its energy efficiency, comfort, and overall performance. It indicates that the building is capable of adapting to the needs of its occupants, optimizing energy usage, and integrating with renewable energy sources or smart grids. On the other hand, a low SRI score suggests that the building lacks such intelligent features, which may result in lower energy performance, reduced flexibility, and fewer benefits for both occupants and the environment.
