nts for Ladybug too. They are based on PVWatts v1 online calculator, supporting crystalline silicon fixed tilt photovoltaics.
You can download them from here, or use the Update Ladbybug component instead. If you take the first option, after downloading check if .ghuser files are blocked (right click -> "Properties" and select "Unblock").
You can download the example files from here.
Video tutorials will follow in the coming period.
In the very essence these components help you answer the question: "How much energy can my roof, building facade, solar parking... generate if I would populate them with PV panels"?
They allow definition of different types of losses (snow, age, shading...) which may affect your PV system:
And can find its optimal tilt and orientation:
Or analyse its performance, energy value, consumption, emissions...

Things have been working swimmingly in many areas of the plugin, but one particular problem has been tough to solve. I have two components that are trying to read/write to the same memory at the same time, causing Rhino exceptions and crashes.
The conflicts appear to be happening between two components -- one is a "Layer Events Listener" that reports essentially what type of layer event just happened. The other is a "Set Layer Visibility" component that toggles the visibility of a list of layers.
The code:
public class LayerTools_LayerEventsListener : GH_Component { /// <summary> /// Initializes a new instance of the LayerTools_LayerListener class. /// </summary> public LayerTools_LayerEventsListener() : base("Layer Events Listener", "Layer Listener", "Get granular information about the layer events happening in the Rhino document.", "Squirrel", "Layer Tools") { }
/// <summary> /// Registers all the input parameters for this component. /// </summary> protected override void RegisterInputParams(GH_Component.GH_InputParamManager pManager) { pManager.AddBooleanParameter("Active", "A", "Set to true to listen to layer events in the Rhino document.", GH_ParamAccess.item, false); pManager.AddTextParameter("Exclusions", "E", "Provide a list of exclusions to stop reading specific events (Added, Deleted, Moved, Renamed, Locked, Visibility, Color, Active).", GH_ParamAccess.list); pManager[1].Optional = true; }
/// <summary> /// Registers all the output parameters for this component. /// </summary> protected override void RegisterOutputParams(GH_Component.GH_OutputParamManager pManager) { pManager.AddBooleanParameter("Initialized", "I", "Whether the listener changed from passive to active.", GH_ParamAccess.item); pManager.AddTextParameter("Document Name", "doc", "Name of the Rhino document that is changing.", GH_ParamAccess.item); pManager.AddTextParameter("Layer Path", "path", "Path of the modifed layer.", GH_ParamAccess.item); pManager.AddIntegerParameter("Layer Index", "ID", "Index of the modified layer.", GH_ParamAccess.item); pManager.AddIntegerParameter("Sort Index", "SID", "Sort index of the modified layer.", GH_ParamAccess.item); pManager.AddTextParameter("Event Type", "T", "Type of the modification.", GH_ParamAccess.item); pManager.AddBooleanParameter("Added", "A", "If the layer has been added.", GH_ParamAccess.item); pManager.AddBooleanParameter("Deleted", "D", "If the layer has been deleted.", GH_ParamAccess.item); pManager.AddBooleanParameter("Moved", "M", "If the layer has been moved.", GH_ParamAccess.item); pManager.AddBooleanParameter("Renamed", "R", "If the layer has been renamed.", GH_ParamAccess.item); pManager.AddBooleanParameter("Locked", "L", "If the layer locked setting has changed.", GH_ParamAccess.item); pManager.AddBooleanParameter("Visibility", "V", "If the layer's visibility has changed.", GH_ParamAccess.item); pManager.AddBooleanParameter("Color", "C", "If the layer's color has changed.", GH_ParamAccess.item); pManager.AddBooleanParameter("Active", "Act", "If the active layer has changed.", GH_ParamAccess.item); }
/// <summary> /// This is the method that actually does the work. /// </summary> /// <param name="DA">The DA object is used to retrieve from inputs and store in outputs.</param> protected override void SolveInstance(IGH_DataAccess DA) { bool active = false; List<string> exclusions = new List<string>();
DA.GetData(0, ref active); DA.GetDataList(1, exclusions);
RhinoDoc thisDoc = null;
bool initialize = false;
string dName = null; string activePath = null; int layerIndex = -1; int sortIndex = -1; string eventType = null; bool added = false; bool deleted = false; bool moved = false; bool renamed = false; bool locked = false; bool visibility = false; bool color = false; bool current = false;
if (active) { thisDoc = RhinoDoc.ActiveDoc;
initialize = (!previouslyActive) ? true : false;
RhinoDoc.LayerTableEvent -= RhinoDoc_LayerTableEvent; RhinoDoc.LayerTableEvent += RhinoDoc_LayerTableEvent; previouslyActive = true;
} else {
RhinoDoc.LayerTableEvent -= RhinoDoc_LayerTableEvent; previouslyActive = false; }
if (ev != null) { dName = ev.Document.Name; layerIndex = ev.LayerIndex; eventType = ev.EventType.ToString();
if (!exclusions.Contains("Active")) { if (ev.EventType.ToString() == "Current") { // active layer has just been changed current = true; }
}
if (!exclusions.Contains("Moved")) { if (ev.EventType.ToString() == "Sorted") { // active layer has just been changed moved = true; }
}
if (!exclusions.Contains("Added")) { if (ev.EventType.ToString() == "Added") { // layer has just been added activePath = ev.NewState.FullPath; added = true; }
}
if (!exclusions.Contains("Active")) { if (ev.EventType.ToString() == "Deleted") { // layer has just been added
deleted = true; } }
if (ev.EventType.ToString() == "Modified") { // layer has been modified activePath = ev.NewState.FullPath;
//skip sortindex eventType = ev.EventType.ToString();
if (ev.OldState != null && ev.NewState != null) { if (!exclusions.Contains("Locked")) { if (ev.OldState.IsLocked != ev.NewState.IsLocked) locked = true;
} if (!exclusions.Contains("Visibility")) { if (ev.OldState.IsVisible != ev.NewState.IsVisible) visibility = true; }
if (!exclusions.Contains("Moved")) { if (ev.OldState.ParentLayerId != ev.NewState.ParentLayerId) moved = true; }
//if (ev.OldState.SortIndex != ev.NewState.SortIndex) moved = true; if (!exclusions.Contains("Renamed")) { if (ev.OldState.Name != ev.NewState.Name) renamed = true; }
if (!exclusions.Contains("Color")) { if (ev.OldState.Color != ev.NewState.Color) color = true; } }
} }
DA.SetData(0, initialize); DA.SetData(1, dName); DA.SetData(2, activePath); DA.SetData(3, layerIndex); DA.SetData(4, sortIndex); DA.SetData(5, eventType); DA.SetData(6, added); DA.SetData(7, deleted); DA.SetData(8, moved); DA.SetData(9, renamed); DA.SetData(10, locked); DA.SetData(11, visibility); DA.SetData(12, color); DA.SetData(13, current);
}
static bool previouslyActive = false; Rhino.DocObjects.Tables.LayerTableEventArgs ev = null;
void RhinoDoc_LayerTableEvent(object sender, Rhino.DocObjects.Tables.LayerTableEventArgs e) { ev = e;this.ExpireSolution(true); }
And for the layer visibility component:
public LayerTools_SetActiveLayer() : base("Set Active Layer", "SetActiveLayer", "Set the active layer in the Rhino document.", "Squirrel", "Layer Tools") { }
/// <summary> /// Registers all the input parameters for this component. /// </summary> protected override void RegisterInputParams(GH_Component.GH_InputParamManager pManager) { pManager.AddBooleanParameter("Active", "A", "Set to true to change the active layer in Rhino.", GH_ParamAccess.item, false); pManager.AddTextParameter("Path", "P", "Full path of the layer to be activated.", GH_ParamAccess.item); }
/// <summary> /// Registers all the output parameters for this component. /// </summary> protected override void RegisterOutputParams(GH_Component.GH_OutputParamManager pManager) { pManager.AddIntegerParameter("Layer ID", "ID", "Index of layer that has been activated.", GH_ParamAccess.item); pManager.AddBooleanParameter("Status", "St", "True when the layer has been activated.", GH_ParamAccess.item); }
/// <summary> /// This is the method that actually does the work. /// </summary> /// <param name="DA">The DA object is used to retrieve from inputs and store in outputs.</param> protected override void SolveInstance(IGH_DataAccess DA) { bool active = false; string path = "";
if (!DA.GetData(0, ref active)) return; if (!DA.GetData(1, ref path)) return;
int layer_index = -1; bool status = false;
if (path != null) {
Rhino.RhinoDoc doc = Rhino.RhinoDoc.ActiveDoc; Rhino.DocObjects.Tables.LayerTable layertable = doc.Layers;
layer_index = layertable.FindByFullPath(path, true);
if (layer_index > 0) { // if exists RhinoDoc.ActiveDoc.Layers.SetCurrentLayerIndex(layer_index, true); status = true; } }
DA.SetData(0, layer_index); DA.SetData(1, status); }
Now originally I was getting exceptions when changing multiple layers' visibility properties, which would cause the Event Listener to fire and try to read the Visibility property before the memory has been released by the Set Layer Visibility component. That led me to add an "Exceptions" input, that would allow me to disable the reading of Visibility events at the source in the Layer Events listener. That helped me manage about 95% of the crashes I was getting, but I still get strange crashes in other event properties, even when that property shouldn't be affected. For instance, I am getting a crash here on the Name property in the event from the delegate function, even though I am only changing Visibility at any one time:
I have a few ideas but they all seem pretty hacky. One is to try to set a flag that is readable by any component in the plugin -- so that the event listener can see if a "set" component is currently running and abort before causing an exception. The other is creating a delay in the event listener, somthing like 200ms, to allow any set components to finish what they are doing before reading the event. Neither seems super ideal.
Any ideas?
Thanks,
Marc

l operations. Aside from its geopolitical position and commercial significance, Thessaloniki has been for many centuries the military and administrative hub of the region, and beyond this the transportation link between Europe and the Levant. A series of design studies will be put forward to rethink the way by which city environment in Thessaloniki have been affecting its’ population according to changing needs and to visualize such urban shifts on a more hyper specific contextualized construction model. Throughout the investigations on the research agenda, current trends on the habits of architectural practice will be re-visited.
Innovative urban interventions informed by bottom-up rules extracted from existing city conditions will formulate the major focus of design proposals. Design teams will be working with simulation tools and digital fabrication methods throughout the design research phase. The design brief will be initially explored through the combinatorial use of different computational design tools. Methods of connecting form‐finding methods with form‐making techniques will be investigated. Various manufacturing techniques enabling a hands‐on experience on the diverse range of digital fabrication systems will formulate the starting point for the physical tests. Finally, the design and fabrication of a one-to-one scale pavilion will unify the goals of the programme.
Prominent features of the programme / skills developed:
- Participants will be part of an active learning environment where the large tutor to student ratio (5:1) allows for personalized tutorials and debates.
- The toolset of AA Thessaloniki includes Autodesk Maya, Rhinoceros, Grasshopper and Arduino.
- Participants will have access to digital fabrication tools such as 3-axis CNC router, laser-cutter, and 3d-printer.
- Design seminars and lecture series will support the key objectives of the programme, disseminating knowledge on new design anatomies including machinic control, computational space, and complexity in systems, and innovative urban design approaches.
Eligibility: The workshop is open to architecture and design students and professionals worldwide.
Accreditation: Participants receive the AA Visiting School Certificate with the completion of the Programme.
Fees: The AA Visiting School requires a fee of £600 per participant, which includes a £60 Visiting membership fee. The deadline for applications is 15 October 2015. No portfolio or CV is required.
Discount options are available. Please contact the AA Visiting School Coordinator for more details.

ences, so not terribly important in the end. After all, it's not really worth going through a lot of trouble to get a 15% speed increase; 15% faster than slow is still pretty slow.
Also processor speed has pretty much peaked these past few years, there have been no more significant increases lately. Instead, manufacturers have started putting more cores on motherboards, which is something GH unfortunately cannot take advantage of.
Multi-threading (very high on the list for GH2) brings with it a promise of full core utilisation (minus the inevitable overhead for aggregating computed results), but there are some problems that may end up being significant. Here's a non-exhaustive list:
It's not possible to modify the UI from a non-UI thread. This is probably not that big a deal for Grasshopper components, especially since we can make methods such a Rhino.RhinoApp.WriteLine() thread safe.
Not all methods used by component code are necessarily thread safe. There used to be a lot of stuff in the Rhino SDK that simply wouldn't work correct or would crash if the same method was run more than once simultaneously. Rhino core team has been working hard to remedy this problem, and I'm confident we can fix any problems that still come up, though it may take some time. If components rely on other code libraries then the problem may not be solvable at all. So we need to make sure multi-threading is an optional property of components.
There's overhead involved in multi-threading, it's especially difficult to get a good performance gain when dealing with lots of very fast operations. The overhead in these cases can actually make stuff perform slower.
There's the question on what level should multi-threading be implemented. Obviously the lower the better, but that means a lot of extra work, complicated patterns of responsibilities and a lot of communications between different developers.
There's the question on how the interface should behave during solutions now. If all the computation is happening in a thread, the interface can stay 'live'. So what should it look like if a solution takes -say- 5 seconds to complete? Should you be able to see the waves of data streaming through the network, turning components and wires grey and orange like strobe lights? What happens if you modify a slider during a solution? Simple answer is to abort the current solution and start a new one with the new slider value. But as you slowly drag the slider from left to right, you end up computing 400 partial solution and never getting to a final answer, even though you could have computed 2 full solutions in the same time and given better feedback. Does the preview geometry in the Rhino viewports flicker in and out of existence as solutions cascade through the network?

n lofting, though, it makes perfect sense to scale sections independently from the distance between them.
For practical use, I found the graph mapper clumsy; too course and approximate. So I adapted the code I wrote here (Maths + Divide Curve) so that a list of numbers drives the spacing and, optionally(!), the scaling.
When 'Scale by Distance' is false, the numbers in the list determine scaling; '1' is actual size, '0.5' is half size, '2' is twice the size, etc.
When 'Scale by Distance' is true, the distance between the points is used for scaling. This is an indirect effect of the list of numbers (which determines point spacing) and the size of the original shape relative to the curve length.
'Tangent 0' is the curve tangent at each point. It works well for lofting.
'Tangent 1' is the vector between each point and its successor. It works well for orienting solids.
There are still some mysteries... ("Where there is mystery, there is no mastery.")
Lofting doesn't always work well, 'Cap Planar Holes' doesn't work anymore...
I had hoped that this sequence, ".5,1,2,1,.5", would result in:
two half size shapes, one at each end of the curve.
two full size ("1") and one double size ("2") shapes, spaced appropriately.
But I have a mental block about how to achieve that...? :( Instead, I settled for the last of the five shapes being one point short from the end of the curve, and the spacing is off.
Even so, I find this approach easier to use on a practical basis than the graph mapper.
…
y stages of design, mainly due to the large uncertainties that exist in these phases. Optimisation in the early phases may be helpful, but it does not provide the designers with more information on "where to go from here". Once the designer changes a parameter to suit a client requirement, legal requirement or other, the optimised result may very well be thrown out due to the parameter being changed having such a large effect.
I am hosting several workshops and focus groups in the next month (one for students at Victoria University of Wellington, one for architect practitioners and one for engineering practitioners) to teach the basics of Honeybee and Ladybug within Rhino as NZ is very new to any form of distributed modelling methods (using visual language programmes such as grasshopper and dynamo to communicate between design tools and building simulation program tools). In the focus groups, I am not focusing on the tool of Honeybee so much as I am asking the industry its opinions on the feasibility and wishes of developments such as Honeybee.
I find that many informal interviews I have been having have pointed to the question: Would you rather want to know the optimised concept or the most significant design parameters which you should be wary of at the early stages of design?
I am amazed at the capabilities of Honeybee because it has been such a pain to remodel anything for E+ and Radiance in the past. I particularly love the ability to generate hundreds of idfs with varying parameters within 10min, without having to set up some form of macro to do it. The visualisations of Honeybee are awesome! To say the very least. But as someone who is interested in doing a sensitivity analysis, say with Thermal Autonomy, I feel like there is a lacking element to analysis from an engineer and research/academic stand point.
The way I have set up my files actually create 300+ idfs with all the various different parameters. The parameter ranges only vary from a low, typical and high setting for power densities, WWR, schedules and insulation. These have all been drawn from a large 5 year project where we monitored commercial buildings here in NZ to gain a better understanding of data for purposes like this. I then run them in parallel as batch files and re-insert the data back into Honeybee.
What I am playing around with at the moment though is that, due to the fact that the TA component require so many additional components to then analyse the data in that form, and also that it does not simply give a numerical value in % for the space's performance, I need to re-evaluate the csv that it produces for further analysis.
I have only just begun to try doing some form of sensitivity analysis within Honeybee itself, but I was curious if there were already plugins within grasshopper which may already allow some form of sensitivity analysis.…
iles and rad files in this folder :
C:\Users\Sarith\AppData\Local\Temp\radSources (replace my name with yours).
However, the pic file which is created in that folder crashes. So, I tried to hack the process and get an image through a screenshot and ra_bmp.
This is the rendering that I got through Relux:
This is what I got from my own renderings with image that I got:
This is surprising because the material is called Glass. However the radiance definition of the material is :
void colorpict mat_104~19 red green blue surfpic2.pic alignpic.cal tile_u tile_v -s 0.5850001 0.975mat_104~1 plastic mat_104005 1 1 1 0 0
The colorpict on the the first line only modifies color patterns and does not make the material transparent/translucent. Similarly, the plastic type implies that the material won't be transparent anyway.
I don't think this material as defined in Relux is a physically based material. You are probably better off importing the Raytracer materials to Honeybee. Andy Mcneil had an excellent presentation about GlassBlocks in the last Radiance workshop: http://www.radiance-online.org/community/workshops/2015-philadelphi...
The pic file that I generated is here : https://www.dropbox.com/s/5c32layqehdns72/surfpic2.pic?dl=0…
