Description
Return opening/facade, facade minus opening, and that solid remainder divided by facade.
Architectural quantities depend on dimension references, area boundaries, slopes, and construction allowances. A component calculation can describe a proposed geometry without establishing code compliance, structural adequacy, or buildability.
Return opening/facade, facade minus opening, and that solid remainder divided by facade.
When to use this tool
Use Facade Opening Solid Share when you need one explicit architectural geometry component using a common measurement basis.
How to use the tool and how it works
- Enter facadeArea, openingArea. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read openingFraction, solidArea, solidFraction. Use the output convention below.
Require openingArea within positive facadeArea. Return opening/facade, facade minus opening, and that solid remainder divided by facade.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| facadeArea | Facade Area | Required. Finite number; strictly above 0. |
| openingArea | Opening Area | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| openingFraction | Opening Fraction | Required. Finite number. |
| solidArea | Solid Area | Required. Finite number. |
| solidFraction | Solid Fraction | Required. Finite number. |

}Limitations and assumptions
- The supplied areas need compatible scope; no thermal, daylight, structural, fire-safety, or legal glazing criterion is evaluated.
- 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
Check the complete drawings, applicable requirements, and qualified design review before construction.
