May I ask why this happens and how to correct the error?
Thank you very much!…

Descriptions
Ladybug + Honeybee
Ladybug and Honeybee are open source environmental plugins for Grasshopper that help architects and engineers create an environmentally-conscious architectural design.
Ladybug imports standard EnergyPlus Weather files (.EPW) into Grasshopper and provides a variety of 3D interactive graphics to support the decision-making process during the initial stages of design. The plugin also provides further support for designers as they test their initial design options with radiation, sunlight-hour, and shading analyses. Integration with Grasshopper allows for an almost instantaneous feedback and, since the plugin runs within the design environment, the information and analyses are interactive.
Honeybee connects Grasshopper3D to EnergyPlus, Radiance, Daysim and OpenStudio for building energy and daylighting simulation. The Honeybee project intends to make many of the features of these simulation tools available in a parametric way. Just as users have made changes to geometry for years in Grasshopper, now users can parameterize system types, zoning schemes, schedules of operation, daylight sensor placement and controls - all of the “hardcore” simulation parameters that have never been exposed to parametric modeling tools.

teraction for its Correlations cycle, AA Athens Visiting School scales up its design intentions in order to investigate links among discrete individual architectural systems in its 2013 version, Recharged.
Recharged with interconnectivity on different levels, the theme of investigation will revolve around the design of semi-independent design prototypes acting together to form elaborate unified results. The driving force in Cipher City: Recharged is the synergistic effect behind complex form-making systems where interactive design patterns arise out of a multiplicity of relatively simple rules.
In collaboration with the National Technical University of Athens, Cipher City: Recharged will explore participatory design and active engagement modeling and will continue building novel prototypes upon horizontal planes.
As in 2012, the design agendas of AA Athens and AA Istanbul Visiting Schools will directly create feedback on one another, allowing participation in either one or both Programmes.

ies and ideas (in this case agent-based modelling) simply because they are the new cool thing to do and, if we think carefully about how the integration of agent-based modeling will improve the accuracy and usefulness of our models, we are more likely to make lasting contributions through their integration.
For example, it seems vital to me that such agent-based models be grounded in some clear quantifiable observations of human behavior in real buildings as opposed to relying on our own coefficients to represent how valuable we think certain things are to the occupants. I will give an example of two agent-based ideas that I have had - one of which has turned out to seem much more valuable in the long-run because of it's grounding in real-world data and I plan to implement soon.
To start with the more valuable example, ever since I read this awesome book on adaptive thermal comfort (https://books.google.com/books?id=vE7FBQAAQBAJ&printsec=frontcover&dq=adaptive+thermal+comfort&hl=en&sa=X&ved=0ahUKEwjDmO6avNnJAhUD9h4KHXWVBuAQ6AEIHDAA#v=onepage&q=adaptive%20thermal%20comfort&f=false), I have had several ideas for how to integrate the findings of recent comfort surveys into our energy models. Generally, the focus of thermal comfort research seems to be shifting from theoretical human energy balance calculations to surveys of occupant behavior, giving us a lot of great data that helps incorporate these behavioral factors in our energy models. To continue one of the ideas that you mention, Theodore, here is a plot from the book that describes the window-opening behavior of occupants as the indoor temperature increases:
Currently, EnergyPlus does not easily allow you to set such a function for window-opening, as you point out but the incorporation of this behavior seems necessary to produce an accurate model of a naturally ventilated building (since opening all of the windows as soon as the indoor temperature hits 21 C is far from realistic). To get around this, I was thinking of including an option on the nat vent component that will put in a series of IF/THEN nat vent objects that approximate this smooth function through a step function:
IF 19 < indoor temperature < 20 THEN WindowOpening = 10%
IF 20 < indoor temperature < 21 THEN WindowOpening = 15%
IF 21 < indoor temperature < 22 THEN WindowOpening = 21%
IF 22 < indoor temperature < 23 THEN WindowOpening = 35%
...
I am hoping to implement this soon.
To describe the example that I have realized was not so helpful with time, when I was first drafting the idea for high-resolution comfort maps (https://www.youtube.com/playlist?list=PLruLh1AdY-Sj3ehUTSfKa1IHPSiuJU52A), I originally thought that I would develop computer models an animations of occupants moving around the thermally diverse space to make themselves more comfortable. Once I started to get into this, however, I realized that the social characteristics of a space usually have a much larger impact on where people place themselves than the thermal characteristics and it is not until the thermal characteristics become very uncomfortable or the presence of other people is completely removed that the thermal environment dominates the movement behavior. Thus, in order to model the occupant behavior, I would have to code in the relative importance of a large number of these social characteristics in relation to thermal comfort, which would have been a process of me simply making up coefficients to produce cool-looking but somewhat meaningless animations. It is only when my nicely-designed thermal environments were aligned with the social/programmatic characteristics of the space that I could argue that I was justifiably adding value since the thermal characteristics were not in contradiction to or being weighted against the social ones. So, in the end, realized that all I needed in order to produce a good design was to align the thermal environment with the placing of program and the agent-based modelling would not have enabled the production of a much better design. This is the reason why the human silhouettes are manually placed in the thermal animations on the youtube playlist in the above link and is the reason why I do not intend to incorporate agent-based modelling in this particular manner.
Let me know your thoughts on this as I realize I may also be looking at this from a narrow perspective that is not informed by all that agent-based modelling has to offer.
-Chris…
l use Rhino 4.0 and corresponding GH version, as a result i could not open your Rhino file.
Hence in your definition as i see,
1) Spring Force-1 -Connection has 11 'inter' components. The inter components do not have any input data and hence 'orange'. What are the inputs for 'inter'?
2) Spring Force - 2 -'Connection'has 1 point component. Rest length & Cut off has 'mass addition' data. This force is also orange, could u throw a light on this please?
3) Pull to surface - both forces has no point input, hence it is orange too. could u throw a light on this too please?
4) There are 2 x Cartesian product components not connected to anything.
I realise that partially it could be because i'm using lower version of Rhino. However, ur input will be highly appreciated.
Kind Regards,
Agneesh…
each circle's border, let us say 1.0
3) So, the curve will end up with 5 points, in each point will have a circle, each circle will have a different Radius, but the distance in between the borders of each circle is always the same = 1.0 in this case.
4) The end result list here would be like this to evaluate a curve with these values and find the points on the curve:
List = 1, 5, 11, 19 etc If I use these values to eval a line, I will get the perfect points where I can draw the circles.
…
e now contains (40x3x11=)1320 points with a branch structure of {0-39,0-2} i.e
{0;0}
{0;1}
{0;2}
{1;0}
...
{39;2}
with each branch containing 11 points.
I now want to create lines from the points on line {x;0} to {x;1}, {x;1} to {x;2}, and {x;2} to {x;0}, which will give me a triangular grid on each triangle. How do i do this? I think I need to split the tree 40 times to give me 40 single layered trees but I imagine there's a cleverer way of doing this!
This feel like it should be simple, but I;m having trouble working with the double-layered branch structure. Any help would be greatly appreciated!
Thanks,
Matt…
keep the same number of branches.
The way I'm doing it now has the inconvenience of only working for this particular number of branches, and I would like a more general way. Do I need a script or can I solve it with components, path mapper, etc?
-Also, and this one is probably simple but I can't seem to figure it out: I have a tree structure as in fig B, and I want to pick out certain series of branches from it, for example {1;0} to {2;11}. (PathGen seems to only go from {0;0} to a specified item?) So I want to be able to plug in a choice of numbers, and dispatch those branches into separate trees/cull them somehow. What am I missing? In general, I've failed to find a way to pick out all of the "uppermost" level of branches, eg {3;x}.
Any help greatly appreciated!…
