IAQ sensors establish a building profile.
Distributed sensing and data aggregation can include CO2, particulate matter, temperature, TVOCs, and humidity.
The BMS can respond.
May this consequence execute NOW?
A bounded TA-14 examination surface built around a control behavior described in ASHRAE Technical Committee 9.7's Design Guidance for Education Facilities: Prioritization for Advanced Indoor Air Quality, Version 2.0 (2023): IAQ sensing, BMS trending, and real-time HVAC sequence adjustment.
Measurement can lead directly toward physical action.
The BMS receives and trends the evidence.
The guidance describes frequent readings, BMS sharing, aggregation, analysis, thresholds, and verification.
Control logic can change the building.
IAQ alarms can inform HVAC sequence changes such as flushing, increased ventilation, and airflow adjustment in real time.
SOURCE BOUNDARY · ASHRAE TC 9.7 · EDUCATION FACILITIES · VERSION 2.0 (2023)
Elevated classroom CO2. Proposed consequence: increase outdoor-air ventilation.
The control sequence may be technically valid. TA-14 asks a different question at the moment the proposed consequence would cross into reality.
Does this proposed consequence have ADMISSIBLE EVIDENCE, APPLICABLE AUTHORITY, and ESTABLISHED STANDING to become reality NOW?
Is the evidence sufficient, attributable, and current?
Is this exact consequence legitimately permitted within scope?
Do the evidence, authority, actors, systems, and conditions still apply NOW?
Keep the record fixed. Change the presented condition.
Changing a condition does not create new evidence or a new determination. It shows where the historical determination can no longer be presented as applicable.

The frozen demonstration state supports the proposed increase in outdoor-air ventilation.
The record remains fixed. Its applicability boundary becomes inspectable.
The frozen baseline, evidence, determination, and closure remain unchanged.
When a changed condition crosses the evidence boundary, the surface returns NEW ASSESSMENT REQUIRED instead of inventing a result for a test that was never run.
