DESIGN OCCUPANT LOAD

[Steve Jepson]

I would like to have a schedule for calculating the Design Occupant Load per area and dispaly the total of those areas.

I would prefer to use the areas extracted from zones on a certain layer but it could work with fills too.

Can such a schedule be made with ArchiCAD ?

area/300 + other area/100 + other area/500 = Total Design Ocupant Load

Something like that. Do I need ArchiQuant or what ever it's called ?

For various reasons, I'm trying to achieve the same thing using properties.  I keep running into a snag where the EXPRESSION calculator has no way of knowing that my 100 is PEOPLE / SF and says that my expression should equal an AREA instead of Number...

Any help appreciated..

Duane,

Here is the expression we use

(can't copy and paste for some reason)

'Occupant Load' is another property (number) derived from the list of Space Functions

Stuart,

Thanks for the response... I went a slightly different route, but looks like yours might work better... I had to dumb the result into TEXT in order to acheive the UNITS I needed... looks like your version keeps everything as a number...

Does your SPACE FUNCTION list contain a bunch of IF/ THENs? to get LOAD related to the SPACE?  or do you have a different method for that?

[Stuart Smith]

The Space Function property is an Option Set with all the space functions as listed in the IBC

 

The Occupant Load property derives the numeric value from the selected Space Function property using STRTONUM (string to number):

All the user has to to do is select the appropriate space function from the list and the Occ load gets calculated automatically for that zone.

Nicely Done!
