This rule checks that specific efficiency ratios are inside given limits. It also creates a report including all area and efficiency values.
Running this rule requires definition of Gross Area Compartments and defining glazed wall types. It can also require settings of glazed wall components from its tools panel.
The rule parameters are:
-
Minimum USF/GSF Ratio: Usable Office Area divided by Gross Building Area
-
Minimum and Maximum Skin Ratio: Skin Area divided by Gross Building Area
-
Minimum and Maximum Fenestration Ratio: Window Area divided by Skin Area
-
Maximum Public Space/GSF Ratio: Public Space Area divided by Gross Building Area
-
Wall Type Classification: If a wall's construction type is set to be glazed wall in this table, the wall area is totally included in window area.
Analyzing the Results
The rule calculates all ratios mentioned above, and creates issues if they are out of limits.
Reported Data
The rule creates a report containing the following values for each floor and for to whole building:
-
Gross Building Area
-
Gross Building Area w/o Parking
-
Gross Measured Area
-
Vertical Penetration Area
-
PBS Specific Area
-
Floor Rentable Area
-
Usable Office Area
-
Usable Building Common Area
-
Usable Floor Common Area
-
Floor Usable Area
-
USF/GSF ( ANSIBOMA calculation method: Usable Office Area / Gross Building Area, GSA calculation method:Usable Office Area / Gross Building Area w/o Parking)
-
Floor Common Area
-
Floor R/U
-
Basic Rentable Office Area
-
Basic Rentable Building Common Area
-
Building Rentable Area
-
Building R/U
-
Total Rentable Area
-
Public Space Area
-
ANSIBOMA calculation method: Public Space Area / Gross Building Area, GSA calculation method: Public Space Area / Gross Building Area w/o Parking
-
Skin Area
-
Skin Ratio ( ANSIBOMA calculation method: Skin Area / Gross Building Area, GSA calculation method: Skin Area / Gross Building Area w/o Parking)
-
Fenestration Area
-
Fenestration Ratio (Fenestration Area / Skin Ratio)
Usable and rentable areas are calculated according to the ANSI/BOMA standard. They are shortly described in Area Calculation.
Rule Tools
Tools panel of the rule allows you to set walls to be glazed walls. You can either set type of the selected walls to be glazed wall types, or set an individual wall to be a glazed one. You can also highlight all glazed walls in 3D view.
