Methodology

How the estimates were built: data sources, modelling approach and validation steps.

Research approach

A market size is a claim about the world, and a claim is only as good as the route to it. Every study is built upward from units and prices — what is actually produced, sold or performed, at what it actually changes hands for — rather than from a headline figure divided downwards. Disclosed company revenue is then used to check that build, not to produce it.

Market size estimation, this report

The estimate is built upward from installed-unit volumes: shipments of KNX-certified actuators, sensors and system components tracked against the KNX Association's own certified-product registry, multiplied by realised average selling prices reported through electrical-wholesaler price lists for Europe, North America and the Gulf states. Regional unit counts are weighted by construction-permit and non-residential floor-area data to allocate volume across commercial and residential projects. The resulting bottom-up figure is then checked against the disclosed building-automation or KNX-adjacent revenue lines reported by Schneider Electric, ABB, Siemens, Legrand and Hager Group in their segment filings; where a company's disclosed growth diverges from the unit build, the unit-price or attach-rate assumption for that region is revisited and corrected rather than the two figures being averaged.

The four stages

The same sequence runs behind every published study, whatever the industry. The order matters as much as the steps: the segment axes are fixed before any number is collected, so the model is never reshaped to fit whatever data happens to turn up.

What the build rests on, and what checks it

The two are not interchangeable. The left column produces the number; the right column tests it. When the check disagrees with the build, the answer is to find which bottom-up assumption is wrong — a unit count, a price, a take-up rate — not to split the difference between them.

The bottom-up build rests on
  • Volume actually transacted — units produced, installed, dispensed or procedures performed, counted at the level each is genuinely recorded
  • Realised pricing by tier and channel, rather than one blended average applied across the whole market
  • Take-up and frequency: how much of the addressable base buys, and how often it repeats
The build is checked against
  • Disclosed revenue of the companies serving the market, where filings separate it far enough to be usable
  • Buyer-side spending totals — capital budgets, procurement lines, or the output of the end market the product is bought against
  • Trade and customs flows, where the product crosses borders in a separately recorded form

Data sources

Published data establishes what happened. Only the people transacting in a market can say why, and what is about to change — so the two are collected separately and weighted differently.

Primary — who is interviewed
  • Commercial and product leadership at the companies that supply the market
  • Procurement and specification leads at the organisations that buy it
  • Distributors, integrators and channel partners, where the market is served indirectly
  • Regulatory and standards specialists, where approval governs what can be sold at all
Secondary — what is read
  • Company filings, annual reports and investor disclosure
  • Government statistics, customs records and regulatory registers
  • Trade association output and standards-body publications
  • Technical and peer-reviewed literature, where the market rests on a clinical or engineering claim
Primary research design, this report

Interviews are directed at the roles that actually decide a KNX specification: electrical design consultants and system integrators who select the bus medium and device count at design stage, procurement managers at panel and switchgear assemblers who set purchasing volumes, and facilities managers overseeing retrofit budgets in commercial portfolios. Regulatory-affairs contacts at national KNX user-group chapters are sampled to confirm how energy-performance codes are being applied on the ground. Sampling is weighted toward Germany, France and the Benelux countries, where KNX specification is most mature, with a secondary tranche in China and the Gulf states to capture newer-adoption behaviour the European sample would otherwise understate.

Secondary sources, this report

Desk research draws on the KNX Association's own certified-product and manufacturer-member registry, national building-energy-performance registers tied to the EU Energy Performance of Buildings Directive recast, and customs trade data filed under HS code 8537 for control-panel and automation-component shipments. Construction-permit and non-residential floor-area statistics from Eurostat and national statistical offices are used to allocate demand across new-build and retrofit projects. Company-level context comes from the publicly filed annual reports of Schneider Electric, ABB, Siemens and Legrand, read for the automation and digital-building segments in which KNX-relevant revenue sits alongside adjacent product lines.

Desk research runs across proprietary research databases including Factiva, OneSource and Hoovers alongside the public sources above. Modelling and statistical validation are run in SAS and SPSS.

Forecasting

The forecast is not a growth rate applied to a base year. It is built from the drivers that are expected to change, each one stated so a reader can disagree with it.

Forecast approach, this report

The forecast is built from three assumptions carried forward from the historical build: continued phase-in of EU non-residential building-automation-system requirements under the Energy Performance of Buildings Directive recast, a steady shift in device mix toward IP and wireless media as retrofit projects avoid new cabling runs, and average selling prices that decline slowly as Asia Pacific manufacturing volume increases. The anomaly normalised for is the post-2021 component-shortage price spike, treated as transitory rather than carried into the base pricing assumption. For the forecast to hold, adopted building codes must not be delayed or relaxed and component supply must remain at pre-shortage lead times.

Triangulation and validation

No figure enters a report on the strength of one source. Where the two sizing routes disagree the difference is not averaged away — the assumption causing it is isolated, tested against a third independent measure, and either corrected or carried forward as a stated limitation. Historical years are back-tested against the growth actually recorded before any forecast is allowed to run forward from them.

Validation, this report

Each regional build was back-tested against recorded 2020-2024 growth in national building-automation shipment data before being extended into the forecast, and any region where the back-test error exceeded the modelled range was re-based on its own unit count rather than adjusted by a blanket factor. Segment-share shifts, particularly the move toward IP and wireless media and toward retrofit projects, were reviewed against installer and integrator interview feedback rather than left as a trend extrapolation. Sensitivities were tested on the pace of EU code enforcement and on Asia Pacific construction-permit growth, since these two inputs move the forecast total the most.

Confidence and limitations

Where an estimate is firm and where it is not is stated rather than left to be inferred from the precision of the number.

Confidence framing, this report

Confidence is firmest in the European commercial-building and new-construction figures, where certified-product registries and code-driven adoption give a direct, traceable basis. It is weaker in the retrofit and residential splits, where project-level reporting is thin and the estimate relies more on installer interview feedback than on filed data. Asia Pacific unit counts carry the widest band, since manufacturer-level disclosure is limited to a handful of listed suppliers and much of the market is served by companies that do not publish product-line revenue. A material slowdown in EU code enforcement is the clearest event that would force a downward revision.
