Il processo di progettazione integrata è riconosciuto come metodo per ottenere gli elevati livelli di qualità oggi richiesti agli edifici. Con questo approccio diventano sempre più rilevanti il comfort visivo e la gestione dell’illuminazione naturale in relazione al risparmio energetico. Di fatto, il nuovo protocollo Leed v4 riconosce crediti ad hoc e conferma l’importanza della progettazione daylighting per “collegare gli occupanti con lo spazio esterno, rinforzare i ritmi circadiani, ridurre l’uso dell’illuminazione elettrica con l’introduzione della luce naturale negli spazi”.
Una progettazione robusta richiede l’uso di strumenti di simulazione efficaci e Radiance è riconosciuto come uno dei software con le capacità di fornire risultati affidabili. Radiance è utilizzato sia a livello di ricerca che tra i progettisti, ed è tra i più accurati per la simulazione professionale della luce naturale ed artificiale. Non ha limiti di complessità geometrica ed è adatto a essere integrato in altri software di calcolo e interfacce grafiche. Le principali e più versatili tra queste (DIVA4Rhino, plug-ins per Grasshopper e Rhinoceros3D), essendo in grado di facilitare notevolmente le procedure di programmazione, saranno oggetto del corso.
Il corso è rivolto a progettisti e ricercatori che vogliano acquisire strumenti pratici per la simulazione con Radiance al fine di mettere a punto e verificare le soluzioni più adatte alle proprie esigenze. Sono previste lezioni di teoria e pratica con esempi ed esercitazioni volte a coprire in modo dimostrativo ed interattivo i concetti trattati.
Il corso viene riconosciuto con 15 crediti dall’Ordine degli Architetti.
Le domande di iscrizione devono essere presentate entro il 27 aprile 2015.

u can still find some wonky behaviour in GH related to datatrees. My experience is that new users quite quickly get the hang of it once they learn that a tree is in fact not a tree but in the first place set of lists, where the path shows how the pieces of data used to be grouped.
Branch Count checking A component has multiple tree inputs, but has different amount of branches, each having branch count > 2. (While I understand the logic of combining multiple trees, I've not once encounted once that combining a component with e.g. an input of 2 branches and an input of 4 branches to give any kind of sensible output.
Desired behaviour: If a component has branches (each being > 2 path count), the component should throw a warning. ("Strict branches behaviour?). For example: take an offset component, with 6 branches of curves and 5 branches of offsets. It is extremely likely that this is the result of an error earlier in the definition. This works however without a problem - the last branch is repeated again, and it's later on quite hard to discover something went wrong.
Checking branch Count The most important numeric is the amount of branches, and the amount of items in the tree. It's desired that the hovers show the amount of data and the amount of branches.
Desired behaviour
Trees with paths of different rank Trees that contain {0;0} and {0} and {0;0;1} is usually a sign of trouble of not well merged trees, faulty C# components, or just nasty coding habits.
Trim as undo graft instead of flatten Having the trim in the context menu would provide an easy way to undo a graft. Right now the easiest way for many people is to flatten it, and then start all over again - while just getting rid of the last index keeps the underlying history and makes it easier to write reuseable pieces of code when you prepend datatrees to it.
Component to get branch by index, not by path Would be great. Suppose you have a grid of points, grouped by row. It would help to show: "look, this is in the first path, it's called {0;0;1}, it's got 10 points, these points are the first row".
Analogue to using list item to show what is the first point, second point, and so on.
Semantic path names (maybe far fetched) But what if we can add a short name of each method that was executed to the path list, so it can show:
{Slider 0; Series 0; Point 0}{Slider 0; Series 0; Point 1}
{Slider 0; Series 0; Point 2}
{Slider 0; Series 0; Point 3}
{Slider 0; Series 1; Point 0}
{Slider 0; Series 1; Point 1}
{Slider 0; Series 1; Point 2}
{Slider 0; Series 1; Point 3}
Make the input/data matching inside components explicit Can we make it even more obvious that a component is not a black box that's executed once, but in fact an iteration machine that tries to make sense of the inputs that's fed to this box?
Show data combination. How data input A relates to data input B and data input C, is currently very implict and is just plain hard to learn., and required the ability to be able to relate the output back to the input. If we can textually or even graphically show what data matching occured inside a component, it would greatly help the understanding (and debugging) of "what's going on here in this component"
A verbose explanation of the data matching in component A
Iteration one: - Geometry: We take the data item from Branch 0, Position 0: (Point 0,0,0) - Motion: We take the data item from Branch 0, Position 0: (Vector 0,0,0)
Iteration two:
- Geometry: We take the data item from Branch 0, Position 0: (Point 0,0,0)
- Motion: We take the data item from Branch 0, Position 1: (Vector 10,0,0)
Iteration three:
- Geometry: We take the data item from Branch 0, Position 0: (Point 0,0,0)
- Motion: We take the data item from Branch 0, Position 1: (Vector 20,0,0)
etc.
A verbose explanation of the data matching in component B
Iteration one: - Geometry: We take the data item from Branch 0, Position 0: (Point 0,0,0) - Motion: We take the data item from Branch 0, Position 0: (Vector 0,0,0)
..
Iteration seven:
- Geometry: We take the data item from Branch 0, Position 0: (Point 0,0,0)
- Motion: We take the data item from Branch 7, Position 0: (Vector 0,70,0)
..
Iteration 27:
- Geometry: We take the data item from Branch 0, Position 7: (Point 80,0,0)
- Motion: We take the data item from Branch 2, Position 0: (Vector 0,20,0)

used of 180 being for the northern hemisphere and 0 for the southern hemisphere.For the optimal tilt, to my knowledge, they are mostly based on correcting location's latitude through a single formula.TOF component is more sophisticated. It essentially replicates the Solmetric's Annual Insolation Lookup tool.What it does is that it creates a grid of points. Each point represents the calculated annual insolation on the surface (PV module, SWH collector, facade, any kind of surface) for a single tilt and azimuth angle.Each point is then elevated according to the annual insolation values. The mesh is created from that grid of points. The portion of the mesh which is the highest, represents the optimal tilt and azimuth angles. So the higher your "precision_" input is, the more points in a mesh you'll have - thus the more precise final optimal tilt and azimuth will be.For the diffuse component of the annual incident solar radiation for each point the Perez 1990 modified model is used. Direct is from classical cosine law, and Ground reflected component from Liu and Jordan (1963).So TOF component calculates the optimal tilt and azimuth based on annual incident solar radiation, not AC energy....…

[.] Descrizione:
Modulo 1 Il workshop è finalizzato a fornire ai partecipanti i fondamenti della modellazione parametrica e generativa attraverso Grasshopper, plug-in di programmazione visuale per Rhinoceros 3D (uno dei più diffusi modellatori NURBS per l‘architettura e il design). Il workshop mira a gestire e sviluppare il rapporto tra informazione e geometria lavorando sui sistemi di involucro in condizioni specifiche. La discretizzazione di superfici (pannellizazione sia Nurbs che Mesh), la modellazione delle geometrie attraverso informazioni (siano esse provenienti da dati di analisi ambientali, da mappe di colore o da database), l’estrazione e la gestione di informazioni richiedono la comprensione delle strutture dei dati al fine di definire un processo che va dalla progettazione alla costruzione. I partecipanti impareranno come costruire e sviluppare strutture di dati parametrici per informare geometrie ‘data-driven’ e come estrarre le informazioni rilevanti da tali modelli per il processo di costruzione.
Modulo 2 Il workshop, volto a promuovere le nuove tecnologie digitali di supporto alla progettazione e alla fabbricazione, fornirà ai partecipanti, utilizzando Grasshopper, gli strumenti per la preparazione dei modelli 3D di elementi modulari decorativi "bricks & tiles" in argilla la cui successiva prototipazione avverrà tramite fresatura dello stampo con pantografo CNC a 3 assi. Il workshop darà quindi ai partecipanti i fondamenti per l’utilizzo di tale strumento di fabbricazione digitale e si concluderà con la fabbricazione di un proprio modello realizzato durante il corso.

1. Select a building to mount a photovoltaic generator on (seen in Rhino in green).
2. Select a surface within that building to mount a photovoltaic generator on (seen in Rhino in green).
3. Create a Honeybee context surface from that surface.
4. Place a photovoltaic generator on that Honeybee context surface by using the Honeybee generation component. Honeybee_Generator_PV and connecting the context surface to it's input _HBSurfaces. Then you can specify both the performance and the financial data of the photovoltaic generator.
5. Create a Honeybee generation system which consists of the photovoltaic generator in 4. By using the component Honeybee_generationsystem and connecting 4 to its input PVHBSurfaces_. Then you can specify the annual maintenance cost of this system.
6. Run the simulation in Energy Plus by connecting 5. to the input HBGenerators_.
7. Read the results of the simulation:
- The electricity produced by the Honeybee generation system in 5.
- The net purchased electricity of the facility (the Honeybee zone) to which the Honeybee generation system is attached to. This is the electricity consumed by the facility less the electricity generated by the Honeybee generation system.
- The financial costs of the Honeybee generation system; capital, maintenance and replacement costs.
8. Calculate the net present cost of the Honeybee generation system in 5 assuming a 25 year lifetime.
9. Visualise the net present cost.

way everything is consolidated and people can share their thoughts.
1. Cluster rollover tips
Id like to be able to create rollover help text for each cluster input. This could be a right click thing once the cluster is created or something specified before creating the cluster (a string input for the cluster input arrows?)
2. Disconnect all outgoing
I'd like to be able to right click on an output of any component and disconnect all wires coming out of it.
3. Disconnect all selected
It would be cool if you could disconnect all incoming or outgoing wires from all currently selected components (instead of just one at a time).
4. List item dynamic slider
There has been a lot of discussion about dynamic range sliders and the issues that they would cause. Id like one specifically for list item selection. This would be an integer slider that would have a range of 0 to the list length-1. If the range remaps and the previous value is no longer available, I think it's best to have the current value stay as close to the previous value as possible.
5. Cluster slider/toggle inputs
I think it could be valuable to cluster a series of variable inputs (like sliders or toggles) to make a sort of options cluster. In this case you could just have a list of sliders and toggles each connected directly to a cluster output arrow, select all and create your cluster. This would be great with the value list component as well.
6. Have a component that could output the x and y location of actual components on the canvas relative to the top left corner... Not sure exactly what you could do with this but I think someone could do something interesting with it.
7. 3d MD slider. I see the option is greyed out and don't see a way to activate it... Still under development? Seems like it could be just like the color picker. Would be cool.
That's all I can think of right now. I'm sure there will be more to come in the future.
Feel free to comment.

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...
