Blank measurement template
ICY Cooling Science Field Record
Use one row for one direct observation or one derived result. The record preserves operating context, source class, instrument identity and uncertainty without converting screening observations into an unsupported diagnosis.
Before recording
Context makes the number useful.
The template is intentionally blank. It contains no customer record and no example reading that could be mistaken for a field result.
- Do not overwrite a baseline after a change; create a new row linked to the earlier record.
- Use ISO 8601 local date and time plus an explicit UTC offset, and synchronize instruments when sequence matters.
- Record SI values first. Put optional U.S. customary equivalents in a separate clearly labeled field or note.
- Choose one source class: literature summary, GCT field method, field observation, qualified-trade finding, owner report or derived calculation.
- Keep raw readings separate from calculations. Preserve formulas, input record IDs, conversions and assumptions for every derived value.
- Use null for a measurement not taken and explain an omission that affects interpretation. Zero is a measured value, not a blank.
- Identify instrument and calibration status, state dominant uncertainty contributors and do not report more digits than the method supports.
- Record equipment, controls, occupancy, doors and exhaust state with every environmental reading that depends on operation.
- Use non-sensitive project and zone references. Do not place customer identity, personal data, credentials or security-sensitive building details in a public record.
- Separate observed facts, reported statements, interpretations and recommended next actions.
- Record the safety boundary and stop condition. A missing measurement is preferable to an unauthorized or hazardous one.
- Close an issue only against a declared acceptance criterion, preserving failed, inconclusive and no-change results.
