Using FAR/GFR and Ground Coverage

Question

Hi All,

I have recently watched a video which is very impressive, which is very important for urban design.

Designing Our Future – Urban Redevelopment Authority

I have been trying to build similar rule file and functions, but I am not able to get that functions.

@6:00 in the video, there is a function using the GFR and coverage. I am looking to build similar function for FAR/GFR, Ground Coverage and Floor variation that has been shown. Can anyone help me out with this. I am using Advanced 2015.2 version of CityEngine.

Thanks

Hi,

I have tried using recursion to check the floors generated, but somehow its not generating exactly the total number of floors. I have attached the cga script bellow , can you help me where I am going wrong.

Thanks in advance

Yes, you can put another check in your recursion to check if the number of floors reached is above the minimum and below the maximum.  But, then if the minimum is set to something impossible for the max FAR, then you'll have to choose which criteria is more important to obey.

Its been quite some time for this post.

Thanks Cherly, I have used most of the expression suggested by you.

I have some query regarding this, Since we can achieve total number of floors from ((FAR*SiteArea)/SiteArea). Can this be applied with a given Minimum and Maximum floors per lot. So that all the buildings in the plot will not cross total number of floors given and can be randomize the heights between maximum floors and minimum floors.

I hope this make sense, I able to find the logic but its difficult to put in CGA Script.

Regards
