, ed è la zona in cui si manifestano in modo più evidente i temi di soglia, gradiente, variazione, catastrofe, dove le condizioni di limite e transizione possono essere esplorate trasformandole in configurazioni formali e architettoniche interessanti. Il workshop mira ad indagare strategie attraverso cui si manifestano le condizioni di transizione tra ecosistemi, sia in termini spaziali (dalla scala territoriale alla scala dei componenti) che in termini di evoluzione o ciclicità temporale (condizioni critiche come i cicli notte/giorno nelle zone desertiche). Il tema dell'eleganza riguarda il modo in cui il sistema produce un campo armonicamente articolato e differenziato di fenotipi a partire dal genotipo attraverso un processo di "estetica delle forze" guidata attraverso lo strumento digitale.
Il tema sarà dipanato attraverso le giornate del workshop sviluppando aspetti teorici e tecnici dell'approccio parametrico generativo, con particolare attenzione a strategie di design basate su caratteristiche endogene (vincoli interni del sistema) ed esogene (fattori ambientali) allo scopo di stimolare l'esplorazione di soluzioni sistemiche innovative.
Il numero dei partecipanti è fissato a 16 per offrire un tutoraggio proficuo ed una effettiva esperienza di learning ad ogni iscritto.

even (0, 2, 4) then that means the point either never hit it, or went in and out again, meaning it's outside. If it hits an odd number of times, then it must have come from within originally.
The method implements this approach using the mesh bounding box, and then striking a polyline from your test point along a vector that is defined by the upper right corner of the bounding box + a vector of (100,100,100). In the case of your failing points, this is a result of their striking an edge very precisely, which gets counted as 2 hits instead of 1 (as it should be getting captured) and passing false:
Your best bet is probably to roll your own implementation, that tests for multiple vectors:
private void RunScript(List<Point3d> P, Mesh M, ref object A, ref object B, ref object C) {
BoundingBox bb = M.GetBoundingBox(false);
List<bool> inside = new List<bool>();
for (int i = 0; i < P.Count; i++) {
Polyline a = new Polyline(); Polyline b = new Polyline();
a.Add(P[i]); b.Add(P[i]);
a.Add(bb.Max + new Vector3d(100, 100, 100)); b.Add(bb.Max + new Vector3d(100, 150, 150));
int[] fa; int[] fb;
Point3d[] xa = Rhino.Geometry.Intersect.Intersection.MeshPolyline(M, new PolylineCurve(a), out fa); Point3d[] xb = Rhino.Geometry.Intersect.Intersection.MeshPolyline(M, new PolylineCurve(b), out fb);
inside.Add(xa.Length % 2 == 1 || xb.Length % 2 == 1);
checkA.AddRange(xa, new GH_Path(i)); checkB.AddRange(xb, new GH_Path(i));
}
A = inside;
}

izes like 0.6m, 0.8m, 0.9m and 1.2m are the most "common": In cases where mechanical floors are a must (hospitals for instance) a 2.4/2.4 is quite handy (habitable/mechanical per floor). You can try 1.8/2.7 as well (floor/habitable) since 1.8 floor thickness can host HVAC and some decent W truss size. Also 1.6/2.4 (floor/habitable) is used in small buildings. NOTE: see next.
3. Don't forget to include corrugated metal height + concrete screed height + raised floors height: for the latter, say, something like 0.3m (modules + adjustable mounts + free space for electric stuff [boxes etc]).
4. As regards exteriors, Laurent Buzon is a close friend of mine. Contact him directly on my behalf:

3. SolveAdj component has the input to set BC for interior surfaces.
If you want to set them to adiabatic then you can use setToAdiabatic components.
4. For natural ventilation Chris has provided extensive answers including this one.
If the component doesn't work then you need to download the files manually from github and replace the userObjects with the old ones. You have to do it separately for Ladybug and Honeybee which can be painful. Is there anyway to change the firewall settings?

hilst settings concern only the currently selected instance.
For instance assume that you are in the Bermuda Shorts business and you want various ideas concerning a new ad campaign:
Or assume that the 4 horsemen want from you to quickly present some concept proposals related with a terminal event that they have in mind:
…
Integer = 0 To 9
val *= 2
lst.Add(val)
Next
Since val is a ValueType, when we assign it to the list we actually put a copy of val into the list. Thus, the list contains the following memory layout:
[0] = 2
[1] = 4
[2] = 8
[3] = 16
[4] = 32
[5] = 64
[6] = 128
[7] = 256
[8] = 512
[9] = 1024
Now let's assume we do the same, but with OnLines:
Dim ln As New OnLine(A, B)
Dim lst As New List(Of OnLine)
For i As Integer = 0 To 9
ln.Transform(xform)
lst.Add(ln)
Next
When we declare ln on line 1, it is assigned an address in memory, say "24 Bell Ave." Then we modify that one line over and over, and keep on adding the same address to lst. Thus, the memory layout of lst is now:
[0] = "24 Bell Ave."
[1] = "24 Bell Ave."
[2] = "24 Bell Ave."
[3] = "24 Bell Ave."
[4] = "24 Bell Ave."
[5] = "24 Bell Ave."
[6] = "24 Bell Ave."
[7] = "24 Bell Ave."
[8] = "24 Bell Ave."
[9] = "24 Bell Ave."
To do this properly, we need to create a unique line for every element in lst:
Dim lst As New List(Of OnLine)
For i As Integer = 0 To 9
Dim ln As New OnLine(A, B)
ln.Transform(xform)
lst.Add(ln)
Next
Now, ln is constructed not just once, but whenever the loop runs. And every time it is constructed, a new piece of memory is reserved for it and a new address is created. So now the list memory layout is:
[0] = "24 Bell Ave."
[1] = "12 Pike St."
[2] = "377 The Pines"
[3] = "3670 Woodland Park Ave."
[4] = "99 Zoo Ln."
[5] = "13a District Rd."
[6] = "2 Penny Lane"
[7] = "10 Broadway"
[8] = "225 Franklin Ave."
[9] = "420 Paper St."

Horticulture and Landscape in same time.
The most common plastic materials used as agricultural films are the low density polyethylene (LDPE, with a density less than 0.93 kg m−3), the copolymer of ethylene and vinyl-acetate (EVA)
Also here you can find the characteristics of the flexible materials for greenhouse covers (adapted from CPA, 1992 and Tesi, 2001) as much as i get.
UV-PE Film ( UV-PE~ polyethylene Long life or UV)
Thickness (mm) = 0.18
Direct PAR transmissivity (%) = 90
Diffuse PAR transmissivity (%)= 86
Long-wave IR transmissivity (%)= 65
EVA Film ( EVA~Ethylene vinyl-acetate copolymer)
Thickness (mm) = 0.18
Direct PAR transmissivity (%) = 90
Diffuse PAR transmissivity (%)= 76
Long-wave IR transmissivity (%)= 27
and here you will find the global heat transfer coefficient’ (K in W m−2 °C−1) for the above greenhouse covering materials, measured under normalized conditions (temperatures: exterior: −10°C, interior: +20°C, wind: 4 m s−1). (Source: Nisen and Deltour, 1986.)

Single PE 8.8-9.0 7.1- 7.2
Single EVA 7.8 6.6
Note : the PAR radiation (photosynthetically active or photoactive radiation and its the amounts to 45–50% of the global radiation; Berninger, 1989)
The name PAR is used to designate the radiation with wavelengths useful for plant photosynthesis. It is accepted that the PAR radiation ranges from 400 to 700 nm (McCree, 1972), although some authors consider the PAR from 350 to 850 nm.
The composition of the radiation changes with time, as a function of the Sun’s elevation and the cloudiness. When the Sun is low over the horizon, the short wavelengths are reduced (less UV and more red). The clouds reduce the amount of energy, greatly decreasing the NIR.
The PAR proportion in relation to the global radiation increases with scattering (diffusion). It is lower with clear sky and in the summer (45–48%).
