Where the knowledge this platform relies on comes from: research bodies, journals, programmes and the themes on which the evidence is strong, mixed or weak. Not a decorative bibliography but an account of the evidence base.

Themes and evidence strength
Sources and institutions
Research and professional bodyEurope
EuroFM
European network of FM research, education and practice, with an annual research conference and published proceedings.
Use it for
Current European research, cross-country comparison and access to researchers who contribute to standards.
Caution
Conference contributions vary in peer review; do not treat proceedings as automatically equivalent to journal articles.
Facility management programmes and applied research groups at institutions including Hanze, Saxion, Breda University and The Hague University, producing practice-oriented research in the Dutch context.
Use it for
Regieorganisatie, hospitality, public procurement and Dutch professional practice.
Caution
Much output is Dutch-language and practice-oriented; hard to find internationally and rarely replicable.
Programme and research groupEurope
Europese onderzoeksgroepen
Research groups in Denmark, Norway, Finland, Switzerland and the United Kingdom, among others, connecting FM with real estate, workplace and building performance.
Use it for
Workplace research, user satisfaction and the link between FM and corporate real estate.
Caution
National context often drives the outcome; always read results against local labour market and legislation.
Benchmark and data collectionInternational
Commerciële benchmarks
Cost data and performance comparisons from consultancies, trade bodies and providers.
Use it for
Order-of-magnitude cost and broad market movement.
Caution
Definitions of area, scope and overhead differ per participant. Without a shared measurement standard a benchmark mostly measures definitional differences — precisely the warning in the withdrawn EN 15221-7.
Themes and evidence strength
Indoor environment and performance
Strong evidence
What is reasonably established
Temperature, ventilation and air quality demonstrably affect complaints, absence and cognitive task performance. This is one of the few FM-relevant domains with repeated, controlled studies.
What is not established
Translation into euros per employee is uncertain. Effect sizes vary widely by task, population and climate.
For critical plant with known failure patterns, condition-based maintenance demonstrably yields less unplanned downtime than purely calendar-driven maintenance.
What is not established
The widely cited savings percentages come mostly from vendor material. For non-critical assets the business case is often weaker than presented.
Studies indicate the quality of the client function correlates more strongly with outcome than the sourcing form itself.
What is not established
There is no reliable evidence that IFM or TFM structurally outperforms bundling or single-service. Comparisons are rarely corrected for scope, baseline and selection effects.
Reliable asset and space data are a precondition for almost every other improvement. That is broadly supported.
What is not established
The return on digital twins in operation has barely been independently researched. Almost all published cases come from parties with a commercial interest.
The gap between designed and actual energy use is large and well documented; operation and behaviour explain a substantial part of it.
What is not established
Which facility interventions structurally deliver the most effect differs per building and climate. Generic measure lists have little predictive value.
