The purpose of this rule is to check, that the model has required amount of spaces with specified type and size. The rule creates a report about existing spaces ordered by selected key and size. This rule is recommended to check that spaces in a building match with the required space program.
Running this rule with the default values does not give useful results; this rule has to be configured before use.
The rule parameters are:
The space classification parameter is primarily used to choose the space classification. You can open a space classification in the Classification View, and it will be visible in the space classification parameter in the drop-down list. With the usage of space classification, it provides more precise selection of spaces that are classified.
This table lists the area requirements for specific spaces. The three first columns identified a space; you can use one or more columns in identification. The table has the following columns:
Space Classification: The Space Classification is added so that you can specify the space according to the space classification, which is selected in the space classification parameter, above.
Space Type: The space type. Depending on the source this is not always available. You can use Space Name instead. An empty value matches any space. When you have a model opened, you can select a type from a separate dialog opened from the right side of the table cell.
Space Name: The space name can either be unique or more generic, like Office. Again, depending on the source, this value may or may not be present in the model. An empty value matches any space. When you have a model opened, you can select a name from a separate dialog opened from the right side of the table cell.
Space Number: A value that defines one space uniquely. An empty value matches any space. When you have a model opened, you can select a number from a separate dialog opened from the right side of the table cell.
Required Count: How many spaces matching the Space Type, Name and Number, the model should contain.
Target Area: The area requirement of spaces matching the Type, Name, and/or Number.
Tolerance: How much the combined space area may differ from the tolerance.
You can also read values to this table from Excel.
Target Area Scope:
This section covers two major uses of this rule. One use case is that you can check areas of individual spaces with this rule. This is covered by the "Individual Spaces" option. The second use case is that you should have certain amount of space, for example, for lobbies. In that scenario, you are not interested in the area of a single lobby space. Instead, you are interested in total area of lobby spaces. This is covered by the "Total Area of Spaces" option. The value of 'Required Count' column in the "Required Spaces" table is irrelevant in total area case. If you change from 'Individual Spaces' option to 'Total Area' option, the values in 'Required Count' column are rendered with a hyphen and the column is disabled.
Categorization of Results:
You can select a property from the "Select Property" dialog which comes after pressing the button. The selected property is used to categorize results while checking and, in this case, the results are categorized according to the "Type" property of the spaces.
Space Groups to be Taken into Account:
You can select if space groups are taken into account or not. Or you can check only space groups. The possibilities are:
Ignore Space Groups - only spaces, which aren't space groups, are checked
Check Spaces and Space Groups - spaces, which aren't space groups, AND space groups of selected types are checked
Check only Space Groups - only space groups of selected types are checked
Space Groups Types Taken into Account:
This is enabled only if spaces groups are checked (Consider Space Groups or Check only Space Groups). You can create a list of space group types which are taken into account. Typically, e.g. gross area space groups are not checked.
Analysing the results:
The rule creates issues of spaces that don’t fit the requirements. There can be too many or too few spaces or the space area can differ from the target value. Also, if the building contains spaces that are not specified in the requirements, they are listed.
The rule does not have a report.
The rule does not have any tools.
