Do you have any questions?
Our FAQ section contains the most important information about us and the digitization of buildings. We have compiled the most important questions and provided clear answers so that you can quickly find the information you need. Whether you have general questions, technical questions, or questions about working with us, you will find the answers here.

What is SRI?
The Smart Readiness Indicator (SRI) is an EU assessment tool. The SRI transparently measures a building’s level of smart capability—in other words, how well it is prepared for digital technologies to improve energy efficiency, comfort, and user-friendliness. Among other things, it assesses a building’s ability to adapt to user needs, interact with the energy system, and optimize operations through smart control.
Why should you rely on SRI in the field of building digitization?
The SRI offers a standardized assessment model for the “smartness” or “intelligence” of buildings, especially in terms of building technology. The uniform assessment methodology makes it easier to compare buildings, make informed investment decisions, and implement smart technologies in the building sector in a broad-based and targeted manner.
Is the SRI the same in every country?
The SRI methodology is standardized across the EU to ensure that results are comparable. However, member states decide how and to what extent they use the SRI. The standardized methodology nevertheless enables comparable assessments and the identification of the potential of buildings within the EU and beyond. The SRI can therefore be used to derive well-founded decision-making support in the field of building digitization.
When will SRI become mandatory?
By June 30, 2027, at the latest, a Delegated Act will be adopted in the EU that will require the application of SRI for non-residential buildings with an effective heating or cooling capacity exceeding 290 kW. By June 30, 2027, at the latest, the EU will make it mandatory for SRI ratings to be implemented for certain non-residential buildings – specifically those with an HVAC capacity exceeding 290 kW. This means that, from this date onwards, such buildings will require an SRI certificate in order to officially demonstrate their “smart readiness.”
What project experience does OnSite Solutions bring to the table?
As part of our academic careers, we have already gained extensive experience in the field of building digitization. This includes projects with the public sector and projects financed by industrial companies. Particularly relevant is the unique experience we have gained during the official test phase for the introduction of SRI in the building sector in Germany, appointed by the Federal Ministry for Economic Affairs and Energy (BMWE, formerly BMWK).
What does a digitization strategy with OnSite Solutions look like?
Which digitization measures should you implement in which building and when? OnSite Solutions can answer these and other questions. Based on the status quo of digitization in your real estate portfolio, we derive optimization potential in the area of intelligent building technology according to individual requirements and objectives. In the form of comprehensible catalogs of measures, we bring clarity and future security to the orientation of your building portfolio.
How many buildings do I need to have before I should consult OnSite Solutions?
It is generally possible to create a suitable, customized digitization strategy for any conceivable number of buildings. If you have two or more buildings in your portfolio, it makes sense to analyze your building portfolio and derive measures using OnSite Solutions, especially in terms of cost-effectiveness, because our AI-based solution always maximizes potential for you, even with the increasing complexity of larger building portfolios.
Who can approach OnSite Solutions to obtain a digitization strategy for a building portfolio?
Whether you are a private property owner, commercial property owner, public sector institution, or other stakeholder in the building sector, in the future, we create a customized digitalization strategy for everyone.
What is the nature of your collaboration with technical service providers and manufacturers of building-related software and hardware?
Our goal is to provide targeted and tailor-made packages of measures for the digitalization of building technology in real estate. OnSite Solutions will be happy to work with you in the future to determine the potential of your products and include them in the pool of possible measures. Feel free to contact us!
Can OnSite Solutions also provide general information on the topics of digitalization, SRI, or climate neutrality?
Our future offerings will be complemented by themed workshops, conference presentations, live and online lectures, and other training and exchange opportunities. We would be happy to provide you with information about these and other future offerings. Please feel free to contact us using the contact form.
