International Building Operation Standard (IBOS)

What is IBOS?

Please note, this document was reissued in February 2023 as practice information. It was previously published in February 2022 as a Framework document. No other changes have been made to the document. For more information on the document category changes, see the text part way down on this page Upholding Professional Standards

The International Building Operation Standard (IBOS) is a data-based approach that supports the measurement and management of buildings for strategic decision-making.

As the way we live evolves, there is a need for a people-centric approach to how spaces are managed.

Developed alongside the market, IBOS reaches beyond traditional ways of assessing building performance to add another dimension – user experience - and provides a consistent way to benchmark across a number of properties.

IBOS revolves around five key pillars:

compliance | economics | functionality | sustainability | performance

By assessing against these pillars, buildings can be measured in a consistent way. What pillar does your building perform best on? What can you do to raise the status of your weakest pillar?

IBOS reaches beyond traditional ways of assessing building performance to equip professionals with a range of data. Assessment results can be used to inform decisions around ESG and sustainability, building optimisation and user-experience.  

The framework can be integrated into your own system, or you can use the RICS IBOS self-assessment tool (SAT).

The SAT allows you to:

  • Consistently measure your building against key indicators
  • Generate a percentage-based report
  • Download your assessment

The IBOS framework is for use by anyone who wants to check their buildings against the core pillars. A range of organisations have endorsed it, including large office occupiers, universities, service provider firms and government departments.

    “In a clear, industry-wide document, IBOS helps to consolidate a range of strategies to support asset managers and developers in optimising user experience, health and well-being. Through internal monitoring and reporting, companies can track their progress, benchmark their performance and build upon targets in each given area. It is now widely recognised that proactively operating a building in a responsible, sustainable and healthy way is just as important as its construction. IBOS helps to ensure that post construction performance remains a key consideration and metric for all existing and future buildings”

    "The world as we know has changed and so has our workplace. The pandemic has hyper-increased the focus on safety and wellness as organisations strive to bring employees back to the workplace. Whether an owned campus or a multi-tenanted asset, occupiers and developers will have to partner and bring about this much needed confidence as return back to office gains momentum and ‘Wellness’ at the workplace becomes a necessity. I would like to congratulate, compliment and encourage the RICS, the World’s leading professional body for qualifications and standards as they introduce International Building Operations Standard (IBOS) for property developers and owners to appreciate, implement and benefit"

    "Some of us may see the 21st Century truly starting with the Covid Pandemic but we all agree that creating social value and optimizing the use of resources are the cornerstones of the present and near future. From this perspective I am welcoming IBOS as a vivid tool bringing together the operational performance of the buildings and the users experience. I am also pleased and ready to use IBOS as an educational resource for those real estate and FM professionals who, day by day, are serving the buildings and the people living and working inside them."

  • Dan Hughes

    Director, Alpha Property

    "The effective use of data can provide huge benefits in buildings. However, as the definition of building performance evolves and expands it is vital that there is a robust framework detailing the elements that need to be considered and the corresponding data to be used. IBOS does just this and is a foundational step for the sector to fully leverage data in the years to come - ultimately to drive better performance in buildings whether for people, the planet or finances."

  • Rob Jackson

    Chief Growth Officer, Asite

    “As we prioritise effective management of buildings, improved reporting against evolving legislation, coupled with a proliferation of available data, IBOS will create clarity and ensure this information facilitates consistent reporting and ‘like for like’ benchmarking.”
