TA-14 raised the execution-authority boundary with ASHRAE first. ASHRAE Technical Services directed the Standard 135 question to BACnet contacts, and TA-14 followed that route.
UNITED STATES · SHOWROOM 07 · STANDARDS / BUILDING-CONTROL CONTINUATION
A valid command is not the same thing as
present authority to execute.
This surface continues the bounded U.S. institutional record from EPA Indoor Air into the ASHRAE / BACnet standards layer. It does not restart the examination. It preserves the referral chain already earned and carries forward one unresolved question: after material conditions change, what prevents authority established under the earlier state from persisting silently into physical execution?

ASHRAE / BACNET · GUIDED QUESTION
Interoperability can carry a command. What makes it executable now?
This continuation keeps the standards question narrow. It does not claim an answer from ASHRAE or BACnet; it lets the visitor walk the unresolved pre-execution authority seam.
WHY THIS IS A CONTINUATION — NOT A NEW SHOWROOM
Two independent institutional paths converge on the same technical layer.
The later EPA exchange sharpened the question around changed environmental conditions between prepared action and execution. EPA then independently directed TA-14 to ASHRAE standards.
ASHRAE / BACnet is therefore the next technical chamber of U.S. Showroom 07 — not a claim of ASHRAE adoption, partnership, or agreement.
THE FROZEN QUESTION
What makes the damper allowed to do it now?
Indoor CO₂ supports additional outdoor air under the applicable control logic.
The building-control system prepares the physical action.
Outdoor wildfire PM₂.₅ rises materially before execution.
The new environmental condition is detected correctly.
What withholds, revokes, expires, or requires revalidation of the already-prepared action?
If nothing explicitly says HOLD, does the earlier command execute because absence of refusal has become permission?
STANDARDS-LAYER EXAMINATION
The question is architectural, not rhetorical.
Communication protocol and building-automation interoperability layer under examination.
Semantic interoperability context raised in TA-14’s original standards inquiry.
Independent institutional referral carrying the sharpened changed-condition question back to ASHRAE standards.
1 · LOCATION Does Standard 135, Standard 223, or another ASHRAE mechanism define a distinct pre-execution authority determination?
2 · REVOCATION If authority was valid when a command was prepared, what event makes material changed evidence capable of withholding or revoking it?
3 · REVALIDATION What requires the prepared action to be rebound to the current state before consequence?
4 · BOUNDARY If this is intentionally outside BACnet, where does ASHRAE place responsibility for that determination?
TA-14 HANDOFF
Interoperability can transport a command. It does not by itself establish authority to execute it.
REALITY → RECORD
→Environmental state and provenance.
CONTINUITY → ADMISSIBILITY
→Is the evidence still current and sufficient?
BINDING → COMMIT
→Is this action still bound to current evidence and present authority?
EXECUTION → OUTCOME
Only current authority reaches physical consequence.
BACNET · AUTHORITY-HANDOFF LAB
A technically valid command is not the same thing as present authority to execute it.
Keep the BACnet command technically valid while changing the authority condition at the final boundary. The protocol message can remain well-formed while consequence permission disappears.
CURRENT DETERMINATIONALLOW
Technical validity and present local authority are both established for the exact actuation.

READ THE SEAM: The upstream evidence or institution does not have to become false for permission to disappear. A material change can preserve the earlier record while requiring a new determination before consequence.

PUBLIC-RECORD BOUNDARY
This continuation surface records TA-14 correspondence and referral continuity involving ASHRAE Technical Services, BACnet contacts, and the U.S. EPA Indoor Air Quality exchange. It does not represent ASHRAE, BACnet International, any BACnet committee member, or EPA endorsement, adoption, validation, certification, partnership, procurement, pilot authorization, regulatory recognition, or agreement with TA-14’s architecture or conclusions. ASHRAE and BACnet materials remain authoritative for their own standards and positions. TA-14’s execution-authority framing remains a bounded technical question unless and until a separate record establishes more.
INSTITUTIONAL CONTINUITY RECORD
What happened, when it happened, and what comes next.
Technical question submitted: when does an interoperable, technically valid building command become presently authorized physical execution?
Heather Pierce explains that Standard 135 is outside her expertise and directs TA-14 to BACnet standard contacts for the technical question.
TA-14 follows the referral and asks whether Standard 135 contains a pre-execution authority determination, where it is located if so, or whether that responsibility sits outside BACnet.
After the classroom CO₂ / wildfire PM₂.₅ scenario is sharpened to the changed-condition seam, EPA states it lacks regulatory authority over indoor air quality and refers TA-14 to ASHRAE standards.
The two institutional paths are preserved together: the earlier ASHRAE → BACnet referral and EPA’s later independent ASHRAE referral now converge on the same unresolved pre-execution question.
Continue the existing standards inquiry without treating referral, correspondence, or silence as endorsement or technical agreement.
