a custom ventilation object (Option 2 on the NautralVentilation Type). With this custom object, you can really take control over all of the inputs using the area of the net, the height of it, etc. You probably want to drop down both the wind discharge coefficient and the stack discharge coefficient to account for the fact that the netting will create additional friction and slow down the air slightly. Also, you probably want to use two SetEPAirflow components in tandem and set the angle of the two ventilation objects to be opposite one another (to account for wind-driven cross flow). Your final set of components should look something like this:
To clarify mostapha's comment on constructions and radiance materials, here is an image on how to assign them:
I made some guesses about what the reflectance of your film is.

Also, if you want to get really deep into PAR, you will probably have to find some of your own ways of accounting for the changing color of sunlight at different angles (just the lux and radiation values won't get you accurate results in moles of photons). You might want to check out the Ladybug_Colored Sky Visualizer to get a better sense of sky color with changing sun altitudes.
Hope this helps,

g an open framework for thinking about design as a way of accumulation of different possibilities. We will explore the way how the design intentions and strategies can be embedded deeply in the formation of design, through a set of local interactions, geometrical systems and surfaces. The participants will explore the creative potential of the emerging and dynamic phenomena through the use of a series of algorithmic strategies (grasshopper + plug-ins) for interactive simulation and design optimization. Having the opportunity to experiment with a range of computational tools we will design and fabricate a small pavilion focusing on the properties of aluminum profiles and Etalbond composite material to demonstrate in an artistic way the construction logic of a sustainable and energy saving facade system. The goal of the workshop is to combine technological precision and creativity and connect the architects with the local industries and companies which will provide the material and machinery. The contemporary digital fabrication techniques and the case of CNC (computer numerical control) machines, provide effective connection between design and production and enable the construction of projects into scale 1:1. - See more at: http://faberarium.org/front/workshop2014beta-abstract/#sthash.Ck88FiYD.dpuf…

simple box of Aluminum, I expect an almost similar U-value and lambda, (not equal due to radiation and convection transfer) if the box is 1 m length. But the amounts are very very different. While Al- lambda is 237 W/m.k , Therm calculates the U of the assumed box 4.59 W/m^2.k . I guess this is because of my mistake in assumption of Hc factor, which I don't know how it should be defined.
the assumed Boundary condition for therm calculation was: (interior boundary Hc = 4.65 W/m.k and temp=21 centigrade
exterior boundary Hc = 10 W/m.k and temp= -18 centigrade)
If I put 237 for Hc of both exterior and interior boundaries, the U-value would be 79.47 W/m^2.k.…

Horario: 18:00 – 22.00 Jueves, Viernes y Sábado de 8:00 a 15:00 Hrs. Instructor_ Arch. David Hernández Melgarejo.
http://bioarchitecturestudio.wordpress.com
Objetivos:
El curso está dirigido a cada diseñador, ingeniero o arquitecto que quiere obtener una sólida base en modelado generativo y paramétrico dentro del flujo de trabajo en Rhinoceros.
En el curso se explorarán y construirán estructuras en el espacio paramétrico, incorporando entidades geométricas (Curvas, Superficies, Puntos, etc…) y usando patrones algorítmicos para la generación de estructuras con metabolismos contextualizados.
Cada paso será soportado con ejercicios que gradualmente incrementarán su complejidad.
El alumno aprenderá cómo trabajar con asociación geométrica y parámetros. Para perfeccionar asociación geométrica – asociación entre partes, asociación dinámica – las formas geométricas son generadas al seguir la conexión lógica entre la parte geométrica y sus restricciones, dimensión paramétrica y él proceso dinámico del diseño: Estimulamos el pensamiento relacional para la construcción de Diseño y Arquitectura de alto desempeño.

Los participantes con éste entrenamiento obtendrán las siguientes fundamentos.
· Generar aplicaciones orientadas al análisis, la optimización, documentación del diseño y fabricación.
Palabras clave:
Diseño Computacional, Scripting, Rhinoceros 5.0 + Grasshopper, Parametrización, Análisis, Galapagos, Genetic Solver, Optimización, Fabricación Digital.

adybug are running the same weather file. with the exception that I converted the epw to a wea file using EergyPlus converter so it can be read by ecotect weather tool.
I modified the cooling and heating base temperatureof the CDH-HDH component in order to match those used by ecotect (heating = 18 degC, cooling = 26 degC)
1. What are the units that CDH-HDH component returns ( I guess it should be Kelvin Hours- Kh)
2. Heating deg Hours seams to match perfectly
3. Cooling deg Hours are completely different. LB returns a maximum value of 158.3 for July while ecotect returns a maximum value of 1430 for July.
Please refer to the images
thank you all in advance

radiance parameters to get rid of blotching. To add another level of complexity to my problem, I am running simulations with a translucent material with the following properties: void trans testTrans
0
0
7 0.478 0.478 0.478 0.000 0.010 0.178 0.635
I have had no issues with the renderings when I use clear glazing, as seen on this image:
However the blotching-issue becomes very noticeable when I introduce translucent glazing into the scene:
For the two above cases I used the following parameters:
_av_ is set to 0
xScale is set to 2
_ab_ is set to 6
_dc_ is set to 0.5
_aa_ is set to 0.2
_ad_ is set to 2048
_st_ is set to 0.5
yScale is set to 2
_ps_ is set to 4
_ar_ is set to 64
_as_ is set to 2048
_ds_ is set to 0.25
_pt_ is set to 0.1
_dr_ is set to 1
_pj_ is set to 0.9
_dp_ is set to 256
_dt_ is set to 0.25
_lr_ is set to 6
_dj_ is set to 0.5
_lw_ is set to 0.01
I ran another test with increased Radiance parameters and got the following output:
with the following parameters:
_av_ is set to 0
xScale is set to 6
_ab_ is set to 6
_dc_ is set to 0.75
_aa_ is set to 0.1
_ad_ is set to 4096
_st_ is set to 0.15
yScale is set to 6
_ps_ is set to 2
_ar_ is set to 128
_as_ is set to 4096
_ds_ is set to 0.05
_pt_ is set to 0.05
_dr_ is set to 3
_pj_ is set to 0.9
_dp_ is set to 512
_dt_ is set to 0.15
_lr_ is set to 8
_dj_ is set to 0.7
_lw_ is set to 0.005
Although the second blotching case is much better than the first, it is still very bad for hours when the sun is lower in the sky. The above images are rendered for a clear sky at 18:00 in Germany in a West-facing room.
Sorry for the long post! Can someone help? Kind regards, Örn
