This is an amazing tool. I have been using quite a lot and I found it very useful.
I recently had some problems with the results of a PV shaded analysis and I was hoping to understand your idea on this. I have been using the tool to compare the performance of an unshaded and a shaded array. I came across a case with panels westerly orientated and tilted by 35 degrees. Some of these panels were shaded by the context whilst some others were completely unobstructed. Plotting the percentage difference of AC energy per year between the shaded and the unshaded scenarios I have noticed that the unshaded panels would still get a reduction in AC energy per year. I have run few tests with the shaded analysis script with only one surface, including as context in the Sunpath Shading the sole panel, and I have noticed that the annual shading increases with the panel inclination and the rotation towards East or West. This depends on the shadow analysis which increases the shading in all window meshes which can’t see the panel and “hit” the back of the surface. The greater is the inclination and the easterly or westerly rotation of the panel, the bigger is the obscured area in the Sunpath. Given that the panel is unobstructed, the AC per year should not be the same before and after the Sunpath Shading analysis regardless of the orientation and the inclination?
See below an example of your script with some changes that hopefully will clarify my question.
I want help from Grasshopper user .. I have file AutoCAD for masterplan I want to add it to Grasshopper.
I don't have file GIS, All I had is file dwg and analysis I did by Photoshop as (Existed Landuse, Heights, Street Width, .. etc).I want to make the relationship between building height (with its ducts openings) and width of streets.
What I know that import Autocad in Rihno but the progress to do in grasshopper, I have not enough information about it (I am not professional Grasshopper user ).
And what to import in Rhino is the outline of masterplan not with the existed building .. This is what I know must be done.
All I want to do is a Conceptual urban planning .. I watched a tutorial for it but I don't succeed in do it.
I am using ladybug Photovoltaic surface component to calculate the energy generation from my building facade. However I want to incorporate the shading from the context.
I would like to request you to please advise me the steps to calculating the photovoltaic power generation using ladybug.
I tried using Photovoltaic surface, sunpath shading, do to ac derate factor and then Photovoltaic surface again.
I am confused on the steps. Could you please do me a favor by write it for me.
Hey Djordje! I'm really sorry to bother you but I'm hassling with your plugin and really need your help! Would you be so kind to please take a look at the following screenshot? I am trying to generate a the topography for the following coordinates:
37°57'23.7"S 65°37'54.7"W with a 100 km radius
However, for some reason its not generating the terrain because is says its not possible to connect to the remote server of opentopography.org. I have already waited a couple of hours but it's still not working. Do you have any idea what the solution could be? From some previous posts I understand there is a way to enter the data manually but I truly don't understand exactly what is the information I need or where to get it from. Thank you very very much!!
Thank you I am totally flattered! Yes, I studied Industrial Design at RISD. The first 3d modeling software I was introduced to was Rhino, but I have been using Maya for most of my career. Now that game engines can handle more polygons I want to experiment with Grasshopper.
