example 10.5 is exactly halfway or at 50%, 12 is at 200%, 5 is at -500%. If you were to remap these values into the other domain, their percentages ought to remain the same, ie.:
10.5 = 50% becomes 0 (because 0 halfway -100 to 100)
12 = 200% becomes 300
5 = -500% becomes -1100
The most common use of Remap Numbers is to change a set of measurements to be within a given goal domain. For example if you measure brightnesses using the Image Sampler, you get values between 0.0 (black) and 1.0 (white). However these brightnesses are supposed to control rotational angles between 10 and 45 degrees. Thus, you use a Remap component with the source domain (0.0 to 1.0) and the target domain (10 to 45).…
be done easier, but later on the geometry will change and therefore this seems the better option. But coming back to the problem
First, there were some problems concerning the zone, although it seems solved still the “runenergysimulation” gives the following warning:
1. The simulation has not run correctly because of this severe error:
** Severe ** UpdateZoneSizing: Cooling supply air temperature (calculated) within 2C of zone temperature
Do one of you know what went wrong? It probably will solve most of it.
Second, “set Zone Thresholds” gives the following warning:
1. Solution exception:global name 'maxHumidity_' is not defined
However, the component is missing the max humidity input on the list, has this to do something with the error?
All the components are up to date.
I hope it will be an easy fix.

If you are interested to know more about some of the new developments and see some of the workflows and you are around New York then just stop by. If can't attend in person you can still watch the presentation online. Check the links below. (Make sure to register by Wednesday if you are attending in person.)
2. We would like to show some of the works that you have done with Honeybee and Ladybug during the presentation so if there is anything that you think is interesting and can be presented publicly send it to us at thisisladybug@gmail.com or just post it here. Make sure to let us know who do you want us to credit the image.
3. That's it for now. I copy the information about the presentation below and hope to see some of you there. Thanks for your help and support.

Descriptions
Ladybug + Honeybee
Ladybug and Honeybee are open source environmental plugins for Grasshopper that help architects and engineers create an environmentally-conscious architectural design.
Ladybug imports standard EnergyPlus Weather files (.EPW) into Grasshopper and provides a variety of 3D interactive graphics to support the decision-making process during the initial stages of design. The plugin also provides further support for designers as they test their initial design options with radiation, sunlight-hour, and shading analyses. Integration with Grasshopper allows for an almost instantaneous feedback and, since the plugin runs within the design environment, the information and analyses are interactive.
Honeybee connects Grasshopper3D to EnergyPlus, Radiance, Daysim and OpenStudio for building energy and daylighting simulation. The Honeybee project intends to make many of the features of these simulation tools available in a parametric way. Just as users have made changes to geometry for years in Grasshopper, now users can parameterize system types, zoning schemes, schedules of operation, daylight sensor placement and controls - all of the “hardcore” simulation parameters that have never been exposed to parametric modeling tools.

So far I have been able to make the screen however I need tips and advice on how to rotate the different components on the 1 surface to be 4 different variables i.e. each one a different angle (25*, 45*, -25*, -45*), I want to do these at random.
I have attached the Grasshopper and Rhino file in hopes that someone will be able to assist! Hopefully what I want to do is also clear enough to understand
Thanks in advance!!…

But somehow, it doesn't seem to work when i do the same.. does anyone know why?
