a with high impact and far from easy to customize.
I'm trying to use and understand the Dragonfly_Boundary_Layer_Parameters block, whose parameter setting seems to have a huge impact on the UHI results. In particular the nightBndLayerHeight parameter. First of all, the default value in the doc (800m) does not correspond to the one in the code (80m). After having set it at 800m with a constant block, the RunUWG component doesn't run until the end, giving the following error message : "Error in ReferenceSite/VerticalDifussionModel (line 141) / Error in xml_new (line 394)". It seems that some combinaisons of nightBndLayerHeight / referenceHeight work (80 / 100 or 800 / 800) and others not (800 / 100).
Does that comes from the model preparation? Or the UWG algorithm itself?
I tried to find for some "tables" linking these weather layers to the different urban typologies... without success. Would have someone ref / paper recommandations?
Kind regards,
Rom

orward polygon modelling combined with a subdivision surface method to smooth the modelled polygon control cage (see this andthis).
The Weaver Bird plug-in has several methods for subdividing and smoothing a mesh including the probably best known method Catmull-Clark as well as laplacian smoothing.
Although Grasshopper is becoming better at handling mesh construction and modelling you might want to consider packages such as 3ds Max, Maya, Modo or Blender for doing the initial cage (they all have most of the standard tools one would except from a polygon modeller). For Rhino there is also the funky fusion between subdivision surfaces and NURBS called T-Splines (gave it a spin a few weeks back, has some pretty decent polygon modelling tools actually).…
roader than this. IFC (Industry Foundation Class) as an open BIM format permits users with the choice of other software they work with. From Grasshopper you can choice to use the model data in Digital Project, Archicad, Microstation, Tekla and beyond. http://buildingsmart-tech.org/implementation/implementations
But there is much scope for improvements in the implementation of model importing/exporting in all software. This is also why I decided to develop a Revit Addon (I can reuse 80 to 90% of my existing c# code) to import the data within this environment. But again this enabling workflows from all the software above plus Rhino/Grasshopper into Revit.
Certainly I think the work of the others is impressive and in areas I haven't really broached yet. But given demand for these aspects I will certainly be looking at it.
Look forward to hearing other thoughts and observations.

temperature.
I changed it and things are clearer, yet now I became intrigued by a discrepancy between what is reported by the "conditionOfPerson" and the "percentOfTimeComfortable" outputs. At first glance would seem that they are reporting the same thing in different manner, but they both provide different outcomes (See pic).
Why is that the case?
Shouldn´t the "conditionOfPerson" output had to incorporate the values within the threshold of 80 or 90% (in case that is not happening)?
Any comments?...
PD: The AdaptiveComfortChart doesn´t provide any output data. Not that I wan´t to rush any one out to fix it, but I just want to report it.
Thanks!,

s random reduced with the random reduce component.
Then the random reduced surfaces, is extruded in z direction with negative factor, The plane surface is also extruded in z direction with negative factor, then i used Trim solid, and had about 40 boxes cut in the xy plane with different hight.( hight is from the flowing surface)
The i open a new grasshopper file, and take brep container, and get one of the boxes cut in xy plane, but if i use isotrim on the brep faces or subdivede quad from lunchbox, the divide component show orginal extruded surface and not the smaller one i got after using Trim solid, on the extrusion.
is it clear or you need the file, and have anyone a answer
thank you

orders from bottom to top. There are three pre-set heights: 20,000 / 50,000 / 80,000 (or 20, 50, 80 meters, I'm working in mm).
So if the three cantilevering volumes would be numbered 0,1 and 2, then I'm looking for a way to let Grasshopper generate the following:
A = 20m-position
B = 50m-position
C = 80m-position
(A,B,C):
0,1,2
0,2,1
1,0,2
1,2,0
2,0,1
2,1,0
Attached is wat I have so far, I have only managed to make simple translations per geometry.

summer because of the relative humidity of outdoor air will be over 80%.
I want to set the schedule like this
1) cooling setpoint to be 27C degree and max humidity to be 50%.
2) when the outdoor air temperature is lower than 27C, open the windows and ventilation naturally.
3) Air conditioning and dehumidification are needed only when the occupancies are at home (almost at night) and Natural ventilation is not to be.
4) Accept the indoor air relative humidity to be almost 100% when dry bulb temperature is lower than 27C.
Now, I set the air conditioning schedule as cooling setpoint schedule, but there are no components to set a dehumidification setpoint schedule.
The dehumidifier keeps working all day whichever the windows are opening or not.
How can I stop the dehumidifier during the windows open?
thank you.…
llowing for higher skyline and construction areas along public transportation corridors. Up until now, neighborhoods once characterized by two-story houses, gardens and ground- floor open shopfront programs, have been completely transformed by the introduction of fortressed monolithic residential and office towers, which lack any sort of urban street life.
The new master-plan, however, now requires buildings to have an open street façade to accommodate multiple programs. Led by tutors from UNStudio (www.unstudio.com), the AA Visiting School São Paulo will address the changes being prescribed by the new masterplan through the redefinition of the tower typology in the extending of the ground of street culture, green landscapes and ecological mediation along the vertical axis of these buildings. For this, the workshop will teach advanced digital design and fabrication techniques to explore a series of novel differentiating structural and environmental organizations in the redefinition of the São Paulo skyscraper.
