Comment on: Topic 'A very strange PLine (actually a Tube on it)': full solution - ALL included - in Microstation is 2Mb) so I can't attach it here. Of course this is not made in Rhino. Anyway, here's a 3D PDF with the components in place. I would be interested if someone has any idea how to do similar stuff in GH.

Comment on: Topic 'Finding an optimal size of PV panel in given array.': to position our PVsurface rows, the glass panels are not shading the PVsurfaces beneath them. If they would have shaded them, we could have supply them to the coniferousTrees_ input and set the coniferousAllyearIndex_ input to the transmittance of glass panels (around 0.5 depending on the glass type). But as these are just assumptions, you can always put everything into the context_ input, except for the threes.For literature: there are a number of papers with detailed explanations on how shading affects a cell/module/array.Ladybug Photovoltaics components use a generalized shading approach where shading losses are integrated into other system losses (that's what the DCtoACderateFactor_ input is for).You can read more about shading method in here.This article on PV shading is very useful. On three pages, it closely replicates the way Sunpath shading component is working.If you have any other issue, let me know.…; Added by djordje to Ladybug Tools at 5:05am on May 29, 2016

Comment on: Topic 'Error in DS parameters with 2 shading states.': calc based on (http://ibpsa.org/proceedings/BS2007/p231_final.pdf) . To do this you'd have to do a single point vertical illuminance calc, which is very easy with Daysim. This result is valid only for those hours for which sun isn't directly visible in your field of view. 2. Identify those hours for which sun is visible from your view point based on sunlight hours calculations. 3. Run a glare calculation for those hours. You can probably pick one-in-three cases and cut down the time for calcs further. 4. A more invasive method, described in (https://www.ibpsa.org/proceedings/BS2009/BS09_0944_951.pdf), requires getting illuminance values from daysim and luminance-based values from evalglare. That will require some additional outputs to be added to the existing Honeybee_Glare Analysis component. Clear all of this with your advisor first!…; Added by Sarith Subramaniam to Ladybug Tools at 10:21pm on February 27, 2017

Topic: Radiance Trans Material question.: " by David Mead (http://radiance-online.org/community/workshops/2010-freiburg/PDF/DavidMead.pdf). It was very helpful but still I'm not confident with this kind of material. I'll explain shortly my design. I'm trying to bring natural light deeper into a generic building. To do so, I want to use a system in which a mirror outside the facade directs the sunlight through a horizontal shaft composed of mirrors on the upper part and on the sides with a "membrane" on the lower side defined as a "Trans Material". My goal is to obtain an effect like the one showed in the attached photo. It's a skylight make of opaque semi-transparent plastic. Does anyone know any good parameter to simulate that? I'm attaching also a little section and the gh file. Thanks everybody for your help. Alessandro…; Added by Alessandro Corso to Ladybug Tools at 8:17am on December 8, 2015
