Description
Calculate marked damp area as a share of inspected area.
Environmental-health records connect sampled matrices, background references, observed areas, service dates and contact durations. An areal loading differs from a bulk or airborne concentration, and a censored result label differs from a quantified value. These summaries do not establish safe conditions or individual health risk.
Calculate marked damp area as a share of inspected area.
When to use this tool
Use Housing Damp Area Fraction when checking the stated environmental-health record, measurement basis or time convention.
How to use the tool and how it works
- Enter markedDampArea, inspectedArea. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read markedFraction, otherInspectedArea. Use the output convention below.
Require inspectedArea>0 and markedDampArea within [0,inspected]. Return marked/inspected fraction and inspected-marked other area.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| markedDampArea | Marked Damp Area | Required. Finite number; minimum 0. |
| inspectedArea | Inspected Area | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| markedFraction | Marked Fraction | Required. Finite number. |
| otherInspectedArea | Inspected minus marked-damp area; not proven dry, mold-free or safe. | Required. Finite number. |

}Limitations and assumptions
- Marked area is supplied; other inspected area is not proven dry or mold-free, and no housing, illness or remediation assessment is made.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use verified sampling and analytical records with qualified environmental-health professionals for actual exposure, remediation, water-quality or care decisions.
