Building Automation (HVAC, BACnet, KNX, smart buildings)
Standards market (btl bacnet conformance listing, knx membership, project haystack + brick semantic-model consortia). The Kin Score Market layer reads each provider in its market: who it integrates with, how deep those integrations go, and where the market publishes its own structure. Methodology.
Where this market publishes its structure
- BTL Listing of Tested Products (bacnetinternational.net/btl, ?m=
per manufacturer) machine-readable, 236 manufacturers, 221 with a website; 10 linked (certified_products by device profile) - KNX Association manufacturer members (knx.org/community/manufacturers, 69 pages) machine-readable, 685 members, 648 with a website; 8 linked; contact names/emails never read
- Project Haystack members (marketing.project-haystack.org/about-us) machine-readable, 29 members (6 founding), logo links; 4 linked
- Brick Consortium members (brickschema.org/consortium) machine-readable, 10 members (6 commercial); 4 linked; academic held
- BTL listing archive (bacnetinternational.net/btl/archives.php) not machine-readable: not read: superseded listings, not current conformance
- KNX certified product database (ETS catalogue / my.knx.org) not machine-readable: login required
- BACnet International member directory not machine-readable: members-only
- ASHRAE (SSPC 135) not machine-readable: the standards body; no implementer or conformance register
- Project Haystack / Brick tagging adopters not machine-readable: no adopter list published; membership is the only structured list (project-haystack.org/about/members 404)
- LonMark certified products / DALI Alliance DALI-2 register not machine-readable: not swept this pass
Own = declares at least one integration itself; covered = visible only because an aggregator, standards body, regulator or partner contract names it; distribution-only = listed only on cloud marketplaces it sells through, a channel reported beside, never counted as its own declared integrations; undeclared = nothing we can read, so no number; declares_compatibility = providers with a `compatible` shape vote, report only (kin, 2026-10-13): never counted as own, never in depth or position.
Taxonomy how this market maps onto apis.io
Derived 2026-10-23 from the 74 providers in this market we could resolve in the catalog. The percentage is the share of those providers carrying each one; it describes the market, not the tag or industry. Tag groups have no page of their own yet, so they are listed unlinked.

| Industries | HVAC & Building Automation 99%, IoT & Connected Devices 54%, Climate & Sustainability 30%, Energy 22%, Industrial 20% |
share of resolved cohort carrying it; tags >=0.20 & >=3 members (max 12, junk dropped), tag_groups >=0.20 (cooccurrence, non-cross-cutting; max 8), industries >=0.20 (max 6), areas >=0.10 (max 6; areas are keyword-matched and sparse), capabilities L1 >=0.20 (max 8); derive-market-taxonomy.py
Leaders by position (provisional)
Provisional: grouped by position, depth compared within a position only. Distribution (cloud marketplaces) and iPaaS bridges are counted beside position, never inside it. Unknown-builder listings are left out of position shares and counted here.
