Angeles, which has 12% of the year made comfortable, and Shiraz, Iran, which also has 12% comfortable (assuming default parameters).
Jerusalem also makes sense to me. There is only a maximum possible 9% of the year that is inside the polygon (you'll see this if you set the timeConstant to a very high number). The default strategyPar makes 6% of these hours comfortable and 3% without cool enough temperatures in the previous hours. This seems reasonable to me.
I could be convinced to change the default time constant to 12 hours (instead of 8) as I know that 12 is the default of climate consultant but that seemed really idealized in my opinion. You'll need really high exposed mass and insulation without much internal heat gain to make conditions stable for more than 8 hours in my opinion.
As for the solarHeatCapacity, I get changes when I drop it down to 10 W/m2 or boost it up to 100 W/m2. It's definitely a parameter that operates on an "order of magnitude" scale and little tweaks to it won't change it too much. You can think of this number as representative of a lot of other physical properties: most notably the depth of the space being passively heated and the thermal mass of that space's materials that participate in heat exchange over the time constant. Climate consultant uses a default assumption of 30 W/m2 but, from my calculations, this is likely assuming a space that has a facade to floor area ratio that is greater than 1. If we say that we need to raise the temperature of 10 cm of an exposed concrete floor for passive heating purposes, and we have a facade-to-floor area ratio of 1:
Required solar flux = ((1 facade-to-floor ratio) x (0.1 m3 of concrete) x (2400 kg/m3 concrete density) x (880 J/kg-K concrete specific heat capacity)) / 3600 seconds/hour
This lands you with a required solar flux of 58 W, which is almost twice the 30 W climate consultant default. While me might say that not all 10 cm of concrete participates over the course of a default 8-hour time constant (most of the action is probably within the first 5 cm), we also have to account for things like transmittance of solar though the window, which, for triple pane, is probably only half of the incident solar. So 50 W seemed to be a more reasonable rule of thumb from my perspective, essentially assuming a facade-to-floor ratio of roughly 1 with 5 cm of concrete participating in an 8 hour heat exchange and a little more than half of solar heat getting through a fully glazed window.
Let me know if that makes sense or if you have any suggestions,

s for some solution "as it is" no matter the cost? (that's an extra stupid approach, very old fashioned). Do you use EvoluteTools Pro and/or Kangaroo for "optimization" ?
2. What is the FEA/FIM stuff in use? Do you expect "from/back" interactions? (If this is not doable ... increase this or that etc etc).
3. Do you validate real-life components with FEA/FIM? By what means you design these components? - present and/or future (inside Rhino?). This makes things "interesting" in a variety of ways (we need to extensively talk about that - Skype). The problem is that Rhino IS NOT a feature driven solid modeling app and thus ... a "certain" bottleneck arrives in no time: In the CATIA world you design ("MANUALLY") a parametric history driven component that "complies" to his parent "directives" (say: the Topology) and/or "imposes" his rules to his parent. This is what we call top<>bottom design approach (would become a standard across the AEC industry pretty soon: in around 123 years give or take some). This is far and beyond from what Rhino can do - but we DO make real-life things don't we?
4. Are all these things under a BIM umbrella ? What BIM? What type of details (blue prints) you deliver? (or you just make the thing?).
5. By what means cost is restricting/encouraging the solution? By what means you get feedback from component(s) cost that is outsourced? (i.e. outside your company). Do you monitor all things via some RDBMS? (that's Data Base).
6. What are the long term plans for dealing with such solutions? Using what apps (even in theory for the moment).…
ual not tactile. i havnt touched the roof of my house i have been living in since 25 years yet its a part of my space. its still a visual plane between me and sky ( except that it protects me from rain). anyway, the point was to reconstruct huge cathedrals without moving big amount of earth.I came up with Nuun lense ( i had in sketches, it will be shorter form of this ugly cube, probably in mms) which will line the necessary floors and stairs-wells and towers.
During my experiment I realized this can be used for visualizing architectural spaces in real time, specially for arch student, it could be used as a console, that can replace cad and other 3d softwares. you can draw basic grids, orthogonal shapes ( not Zaha hadid stuff ). I still am very enthusiastic about this idea. I want to see it function some day.
Grasshopper was used to drive poor reflectors through firefly, to bend laser.( it failed badly) Its just for idea if anybody likes to follow, i dont have enough resources but it would make me happy if some day i see students working on realtime laser models and building having virtual ornamentation.
Any architecture/ electronics student who wants to further his research in lasers and its application in virtual modeling can contact me.

y part of existing files, you typically mark the old component as [Obsolete]* and write an entirely new component which has the changes. This allows you to open old files and have them work in the same way as before, by loading the obsolete component instead of the current one. You can then choose to add an automatic upgrader which is a class which knows how to replace an obsolete component with an updated version in situ. You can load all upgraders via the Solution->Upgrade Components... menu.
An upgrader is a class which implements the IGH_UpgradeObject interface. There's also a GH_UpgradeUtil class which provides some useful static methods for doing common upgrade stuff. For example, here's the upgrader for the [Polygon Centre] component:
public class Upgrade_PolygonCenterComponent : IGH_UpgradeObject { public Guid UpgradeFrom { get { return new Guid("{7BD7B551-CA79-4f01-B95A-7E9AB876F24D}"); } } public Guid UpgradeTo { get { return new Guid("{87E7F480-14DC-4478-B1E6-2B8B035D9EDC}"); } } public DateTime Version { get { return new DateTime(2011, 12, 7, 16, 30, 00); } } public IGH_DocumentObject Upgrade(IGH_DocumentObject target, GH_Document document) { IGH_Component component = target as IGH_Component; if (component == null) { return null; }
IGH_Component upgradedComponent = GH_UpgradeUtil.SwapComponents(component, UpgradeTo); Grasshopper.Kernel.Parameters.Param_Point extraParameter = new Grasshopper.Kernel.Parameters.Param_Point(); extraParameter.Name = "Center(E)"; extraParameter.NickName = "Ce"; extraParameter.Description = "Average of polyline edges"; upgradedComponent.Params.RegisterOutputParam(extraParameter);
return upgradedComponent; } }
* This can be done either by adding the string "OBSOLETE" to the component class name, or by adding the [Obsolete] attribute to the component. Do note you have to change the exposure to Hidden, otherwise the obsolete component will still show up on the panels.…

you may know, PCS (from now I will call polar coordinate system with PCS, and cartesian one with CCS) describes point position with 2 values (like x and y in CCS) which are r and theta(r,theta). r is for distance from PCS center, theta is angular dimension which is in 0 to 360 or 0 to 2*pi domain.
To hark back to David's guide line - here it is replaced with guide circle.
Why to sort points like this ? As usual, one image tells more...
Here is logic behind all this stuff :
Find an average point of all given points*
Search for furthest point from an average point*
Create a circle with center at average point and radius = distance from average point to furthest point*
*Steps 1-3 can be replaced with custom hand-made circle, I decided to automate it that way.
For each point find closest point on circle - this will be used for finding theta value
For each point find distance to average point - this is r value
To overcome problem with same theta (t) values (like same x values in CCS), instead of multiplying by 1000, we will use a new create set component. This component creates set of integers, each one representing one unique input value. So if points A, B, C, D, E are (r,theta) :
A (1, 30)
B (2, 30)
C (3, 30)
D (1, 45)
E (1, 60)
Then create set will output list of integers = 0,0,0,1,2 (same theta for A, B, C other theta for D and E). Now its getting really easy - remap r values to domain 0 to 0.5 (or any less then 1), and add integers from create set component to remapped r values.
7. So what we have now is list of floating point numbers : A=0, B=0.25, C=0.5, D=1, E=2
Profit of remapping is that r values will never affect integers representing theta values - and all the information is stored in one floating point number ! By sorting these values we will obtain proper order of points - to complete this, we need to sort points parallel with values.
What's really cool about polar sorting - there could be any amount of points, but polyline connecting all of them will never self-intersect. Probably there is some relation with 2d convex hull.…

2. See this? It's a abstract (for the moment) layout of some WIP thing: Imagine a region where "evenly" random points are placed (and then a random zNoise is added) - then a ball-pivot/delauney triangulation is applied ... then ... :
2. I use my method to create "even" points (I suspect that David's is way better/faster/cooler ... but anyway): after a random point is found (inside the region) an additional check is performed: think of the point as a "candidate" that must "pass" a 2nd constrain: if the min distance from all the already found (random) points is smaller than a user defined one > reject and try again (the "try-again" thing [call it: min distance "loops"] is also user controllable). Thus that C# captured attempts to place 122 points but due to (a) the min distance constrain AND (b) the low (about 8 in this case) amount of "try-again" loops it finishes with "only" 59 (not a big deal for this case). The interesting part is that the attempts required are 1573 (~30 times the random points returned). Of course there's a lot of factors affecting this 1573 (variable) thing ... but don't stick to that.
3. So if David uses a "similar" culling method (add some " " more, he he) ... for 80K points ... well we are talking about a BIG number of attempts.
I can provide you with a "no-even" random points C# that (I assume/guess/hope) can speed things a bit (after all: who's gonna notice an "even" random distribution of 80K points within a micro cube?).
best, Peter
