y using the Honeybee_Update Honeybee component.
The video below (best viewed in full-screen mode) provides an idea of what these components are capable of being used for:
The video below shows how these components can be used in an existing Honeybee project (for additional links please open this video in youtube):
I have uploaded two examples as Hydra files that show how these components can be used for grid-point and image-based simulations:
Example1 : Grid Point Calculations
Example2: Image based simulation
Finally, a more esoteric application is demonstrated in this video:
These components are still in the beta-testing stage. Some of the limitations of the components are:
1. Only Type C photometry IES files are supported at present.
2. Rhino is likely to get sluggish if there are too many luminaires (i.e. light fixtures) present in a scene.
3. Due to the spectral limitations of the ray-tracing software (RADIANCE), simulations involving color mixing might not be physically realizable.
Additional details about photometric and spectral calculations are probably an overkill for this forum. However, I'd be glad to answer any related questions. Please report any bugs or request new features either on this forum or on Github.
Mostapha, Leland Curtis, Reinhardt Swart and Dr. Richard Mistrick provided valuable inputs during the development of these components.
Thanks,
Sarith
Update 16th January 2017:

e a "game changer" regarding lighting simulations and analysis. To harness the power of Grasshopper, the flexibility of Rhino in a lighting specific application is, I believe, already the future.
Because of the above I am a big proponent of Honeybee for the professional environment, but I feel that there are still a few shortcomings... from what I have tried.
1. It should be "photometrically" more comprehensive, not just for illuminance, luminance and energy (W.h). Other quantities are of great importance, namely intensity and flux.
2. Producing documentation is a big advantage (if not the main advantage) of dedicated packages such as Dialux or AGI32, it would be nice to see it as a strong feature in Honeybee as well.
3. Support for Eulumdat would be a nice feature.
4. There is a performance issue with multiple sources as you mentioned. I have tried a "simple" analysis with 120 sources and it takes, indeed, a substantial amount of time to produce the result. Don't know where the bottleneck is, perhaps not Honeybee's to blame, but it is a hindrance in using the software for complex simulations.
5. Material/surface design would benefit from more options.
Finally, do you have a roadmap of sorts and what can the users expect from Honeybee electic lighting in 2017?
Have a great year!! All the best.

ne) graphs, makes a classic VV (vertex to vertex connectivity) Adjacency Matrix based on what Sandbox has to say (the Matrix is not actually required if someone wants to stay 100% in the GH world) and then ...er ... hmm ... attempts to find closed circuits as Microsoft suggests (forgot/lost the link but who cares? not me anyway [see VS stuff attached]).
It's quite faulty (like Windows) ... but is an indication on some things. Try to understand the recursion (critical in most AEC stuff). Recursion means that Matteo calls Matteo who calls Matteo ... until Matteo calls Maria and the loop is over. Notify if you need other recursion C# examples on other things (dozens available).
The working(?) chopped (minus sensitive stuff) real thing next week: just realized that this w/e there's the Malaysian MotoGP (Valentino lost the championship) AND a critical Formula 1 race in Mexico (forza Lewis).
Attached as well the original VS stuff from Microsoft (requires VS 2017)…
aggie experiences her first love, her father leaves her mother at Christmas as a child. After her ex-husband leaves her family at Christmas twenty years later, Maggie forms a protective shield over her heart and her son, Jordan. Jordan, however, sees that Maggie is lonely, and writes letters to God praying for her happiness. Jordan's prayers are answered when Maggie meets his tutor, widower Casey, and forms an instant connection that is stronger than the one she has with Tanner, the fellow divorce attorney she had been dating. When Maggie and Casey begin to fall in love, though, Maggie pulls back. After discovering a coincidental childhood connection with Casey, and reading Jordan's letters to God, though, Maggie must decide if Christmas is the right time to open her heart to love.

onsidered period.
Even if the end of July for the mediterranean climate is not the best period to perform an adaptive comfort analysis (it's just a pretest to define a LB model) I want to refine the Adaptive comfort Chart (AC) by changing the external air temperature data imported from the .epw file with that of monitored data as reported here below:
Where the monitored ext air temperature are in this form (green panel below):
I have used the comfortPar component to set the following parameters:
Adaptive chart as defined by EN 15251
90% of occupants comfortable
the prevailing outdoor temperature from a weighted running mean of the last week
fully conditioned space (even if it is not properly in line with AC as already discussed)
The question is this: the AC component could correctly apply the code below if there is only a list of external temperature data for a restricted period (without indication about the limits of this period) and not for an entire year?
else: #Calculate a running mean temperature. alpha = 0.8 divisor = 1 + alpha + math.pow(alpha,2) + math.pow(alpha,3) + math.pow(alpha,4) + math.pow(alpha,5) dividend = (sum(_prevailingOutdoorTemp[-24:-1] + [_prevailingOutdoorTemp[-1]])/24) + (alpha*(sum(_prevailingOutdoorTemp[-48:-24])/24)) + (math.pow(alpha,2)*(sum(_prevailingOutdoorTemp[-72:-48])/24)) + (math.pow(alpha,3)*(sum(_prevailingOutdoorTemp[-96:-72])/24)) + (math.pow(alpha,4)*(sum(_prevailingOutdoorTemp[-120:-96])/24)) + (math.pow(alpha,5)*(sum(_prevailingOutdoorTemp[-144:-120])/24)) startingTemp = dividend/divisor if startingTemp < 10: coldTimes.append(0) outdoorTemp = _prevailingOutdoorTemp[7:] startingMean = sum(outdoorTemp[:24])/24 dailyRunMeans = [startingTemp] dailyMeans = [startingMean] prevailTemp.extend(duplicateData([startingTemp], 24)) startHour = 24

the post.
10 days ago was the 4th anniversary of the release of the first version of Ladybug and as the title says, I wanted to share with you what 2017 entails for Ladybug Analysis Tools (previously known as Ladybug + Honeybee).
In December 20016 at the AEC Tech Hackathon, I gave a presentation which pretty much covers all I need to write here. I’m copying the links to the videos so you can watch them and I will just highlight the most important topics. Here are the slides that I used for this presentation.
The first major release of 2017 is a new version of the original Ladybug + Honeybee plugins, which will hereafter be referred to as the legacy version of Ladybug Analysis Tools. Now that the plugins have been fully connected to the major open source engines and databases, the majority of changes represent “icing on the cake.” There are a number of new components related to maximizing the visual capabilities of Rhino, including contour map visualizations, components to make rendered animations, texture mapping components for transparent meshes (and connections to VR programs), and stereographic sky projections. Furthermore, the last of the thermal comfort models for local discomfort (drafts and radiant asymmetry) have been incorporated along with components that help calculate discomfort from given geometric and thermal criteria (a simplified downdraft model and a view factor component). There have been a few extensions of OpenStudio/E+ capabilities to get out HVAC system sizing results and to request/search through the hundreds of outputs that E+ offers. Finally, there are a few workflow improvements, including changes to use less memory when building large energy models and a workflow to import HBZones from gbXML. Chris has been leading the development for the legacy version during the last year or so and he deserves all the credits. There is no way to thank him enough for what he does on a daily basis. I can only say that we are all so lucky to have him around!
After the release of the legacy plugin, the next major release of 2017 will be the public release of Butterfly, which is already long overdue. If you are watching the project on GitHub, you should already know that we are very close and are trying to make the final improvements before the release. The release will have its own separate release notes. For now, I want to thank Theodore Galanos and everyone who helped us with their suggestions during the development process. There would be no Butterfly if it wasn’t for Theodore.
Butterfly’s release will be followed by the release of Honeybee[+]. The first release of Honeybee[+] supports most of the functionalities in the current version of Honeybee for daylight simulation plus it addresses many of the current limitations for annual daylight modeling by using Radiance 3-phase method. It should also support Grasshopper both on Windows and Mac as well as Dynamo. There is much more about Honeybee[+] which again will be included in a separate post. I want to thank Sarith Subramaniam and everyone who helped us with testing the code during the development. Honeybee[+] won’t have most of its features if it wasn’t for Sarith.
I also want to thank everyone on the forum who helps other users with questions and solutions. That’s how I and the rest of the developers get the time to focus on the new developments. Yet I didn’t get a chance to update the graph for this year but you know who you are. Thank you!
Finally, I am posting a modified draft from last year February. Chris and I drafted this post last year but never posted it as I was waiting for the “right time” to post it. The “right time” would be when we have free time to answer all the questions but that time seems not to come! We will do our best to reply to your comments as much as we can. Here is that post:
----
Even though we receive comments and ideas from many of you on a daily basis Tim's recent comment [it was recent at the time!] made me think that we should, once more, explicitly ask for your comments while developing the new version of Ladybug (and at some point Honeybee), and also collect the ongoing ones in a single place.
So post your comments, suggestions and wishes here and let us know what can we do to make Ladybug and Honeybee better. Any type of comments are welcome as far as you tell us why you think it is important. Here are a couple of questions to get you started:
- What is currently missing? Why do you think that missing feature is important?
- If you could only change one thing, what would it be and why?
- What do you like the most about Ladybug + Honeybee that you don't want to change in the new release?
- What kind of bottlenecks do you run into? - What have you done with Ladybug + Honeybee that you think it should/could have been done much simpler if we could have made a couple of changes?
- What do you think will be essential/missing from Ladybug for Dynamo?
- ...
Your turn! Let us know your thoughts!
