her people) a tremendous amount of time creating them by hand. Dog Treat was far from perfect, however it was good enough to use almost daily.
Three years is a long time. Since 2016 my Gh knowledge has expanded and I’ve seen how dodgy some of the scripting is. With this in mind I started work on a new build. Many things have been tweaked and some things have been rebuilt from the ground up.
Everything has been designed to be leaner and be a general solution to the problem of creating dog bone corners on geometry for quick, efficient and safe CNC fabrication.
Some of these things are:
Adding prompts about user geometry to make them aware about open curves, varying curve heights and if their geometry had been altered (mostly removing unnecessary points on curves).
Smooth Transfers. If you’re in a rush and need to speed through cutting, smooth transfers mean that a lead in geometry is now created alongside the actual dog bone arc. This means the router bit doesn’t have to come to a minute stop at every corner. This is turned on by default.
Acute Angle Condition If the angle between the two curves adjacent to a dog bone point is acute, previously the dog bone corner was useless. This was because the distance between the end points of the dog bone arc were less than the diameter of the router bit. There are many ways this condition could be addressed. I chose to circumscribe a larger arc based on the original angle between the adjacent curves. While it removes more material from the corner, it minimises tool wear and any potential for material to burn.
Single Curve A single curve can now be input into Dog Treat. It will be output with both internal and external treatments.
I’ll continue to update Dog Treat as the need arises, it’s become somewhat of a hobby now. Maybe one day it will become part of a Plug-in… once I learn to code it though!
Happy Treating!
Hi Everyone,
Here's a tool I've been working on for the past 4 months or so in my free time. It's a dog bone corner generator, however it's a little different to some of the existing ones. It's designed to be used for large amounts of geometry and as such, it avoids using any curve boolean operations that are computationally taxing. You don't have to split your curves up into internal and external lots either, it works it all out so you can be lazy. I've also incorporated Lunch Box's Object Bake Component for a one click operation that bakes geometry back out to Internal and External profile layers.
Let me know how it goes, will update where necessary.
Best,
Darcy

nd improvements. Many of the new features and components announced in the last release have become stable and have emerged from their WIP section. Additionally, after two years of work, we are happy to announce that we finally have full support of an OpenStudio connection within Honeybee, which has ushered in a whole host of new features, notably the modelling of detailed HVAC systems. As always you can download the new release from Food4Rhino. Make sure to remove the older version of Ladybug and Honeybee and update your scripts.
LADYBUG
1 - Solar Hot Water Components Out of WIP
After much beta-testing, bug-fixing, and general development, all of the Photovoltaic and Solar Hot Water components are now fully out of WIP! The main component is based on a Chengchu Yan's publication. Components have been added to Ladybug thanks to the efforts of Chengchu Yan and Djordje Spasic.. See Djorje’s original release post of the solar hot water components for more information on the components that just made it out of WIP.
2 - New Terrain Shading Mask Released in WIP
In addition to Djordje’s prolific addition of renewable energy components, he has also contributed a widely-useful component to generate terrain shading masks, which account for the shading of surrounding mountains/terrain in simulations. While initially added to assist the solar radiation radiation and renewable energy components, the component will undergo development to optimize it for energy and daylight simulations over the next few months. Another new component called Horizon Angles can be used to visualize and export horizon angles. You can test them out now by accessing them in the WIP section. For more information, see Djordje’s release post on the GH forum here.
3 - New Mesh Selector Component
After realizing that the Optimal Shade Creator component has applications to a whole range of analyses, it has now been re-branded as the Mesh Selector and has been optimized to work easily with these many analyses. Specifically, the component selects out the portion of a mesh that meets a given threshold. This can be the portion of a shade benefit analysis meeting a certain level of shade desirability, the portion of a radiation study meeting a certain level of fulx, the portion of a daylight analysis meeting a certain lux threshold, and much more!
4 - Solar Adjusted Temperature Now Includes Long Wave Radiation
Thanks to a question asked by Aymeric and a number of clarifications made by Djordje Spasic, the Solar Adjusted Temperature component now includes the ability to account for long-wave radiative loss to the sky in addition to it original capability to account for short wave radiation from the sun. As such, the component now includes all capabilities of similar outdoor comfort tools such as RayMan. The addition of this capability is also paralleled by the addition of a new horizontalInfraredRadiation output on the ImportEPW component. See the updated solar adjusted example file hereto see how to use the component properly.
5 - Support for both Log and Power Law Wind Profiles
In preparation for the future release of the Butterfly CFD-modelling insect, the Ladybug Wind Profile component now includes the option of either power law or log law wind profiles, which are both used extensively in CFD studies. Thanks goes to Theodoros Galanos for providing the formulas!
6 - New Radiant Asymmetry Comfort Components
Prompted by a suggestion from Christian Kongsgaard, Ladybug now includes components to calculate radiant asymmetry discomfort! For examples of how to use the components see this example file for spatial analysis of radiant asymmetry discomfort and this example for temporal analysis.
7 - Pedestrian Wind Comfort Component Released in WIP
In preparation for the impending release of the butterfly CFD-modelling insect, Djordje Spasic with assistance from Liam Harrington has contributed a component to evaluate outdoor discomfort and pedestrian safety. The component identifies if certain areas around the building are suitable for sitting, building entrances-exits, window shopping... based on its wind microclimate. Dangerous areas due to high wind speeds are also identified.You can check it out now in the WIP section.
HONEYBEE
1 - New HVAC Systems and Full OpenStudio Support
After a significant amount of development on the part of the OpenStudio team and two years of effort on the part of LB+HB developers, we (finally!) have full support for an OpenStudio connection within Honeybee. By this, we mean that any energy simulation property that can be assigned to a HBZone will be taken into account in the simulation run by the OpenStudio component. The connection to OpenStudio has brought with it several new capabilities. Most notably, you can now assign full HVAC systems and receive energy results in units of electricity and fuel instead of simple heating and cooling loads. This Honeybee release includes 14 built-in HVAC template systems that can be assigned to the zones, each of which can be customized:
0. Ideal Air Loads 1. PTAC | Residential 2. PTHP | Residential 3. Packaged Single Zone - AC 4. Packaged Single Zone - HP 5. Packaged VAV w/ Reheat 6. Packaged VAV w/ PFP Boxes 7. VAV w/ Reheat 8. VAV w/ PFP Boxes 9. Warm Air Furnace - Gas Fired 10.Warm Air Furnace - Electric 11.Fan Coil Units + DOAS 12.Active Chilled Beams + DOAS 13.Radiant Floors + DOAS 14.VRF + DOAS
Systems 1-10 are ASHRAE Baseline systems that represent much of what has been added to building stock over the last few decades while systems 11-14 are systems that are commonly being installed today to reduce energy use. Here is an example file showing how to assign these systems in Honeybee and interpret the results and here is an example showing how to customize the HVAC system specifications to a wide variety of cases. To run the file, you will need to have OpenStudio installed and you can download and install OpenStudio from here.
In addition to these template systems within Honeybee, the OpenStudio interface includes hundreds of HVAC components to build your own custom HVAC systems. OpenStudio also has a growing number of user-contributed HVAC system templates that have been integrated into a set of scripts called "Measures" that you can apply to your OpenStudio model within the OpenStudio interface. You can find these system templates by searching for them in the building components library. Here is a good tutorial video on how to apply measures to your model within the OpenStudio interface. Honeybee includes a component that runs these measures from Grasshopper (without having to use the OpenStudio interface), which you can see a demo video of here. However, this component is currently in WIP as OpenStudio team is still tweaking the file structure of measures and it is fairly safe to estimate that, by the next stable release of Honeybee, we will have full support of OpenStudio measures within GH.
2 - Phasing Out IDF Exporter
With the connection to OpenStudio now fully established, this release marks the start of a transition away from exporting directly to EnergyPlus and the beginning of Honeybee development that capitalizes on OpenStudio’s development. As such THIS WILL BE THE LAST STABLE RELEASE THAT INCLUDES THE HONEYBEE_RUN ENERGY SIMULATION COMPONENT.
The Export to OpenStudio component currently does everything that the Run Energy Simulation component does and, as such, it is intended that all GH definitions using the Run Energy Simulation component should replace it with the OpenStudio component. You can use the same Read EP Result components to import the results from the OpenStudio component and you can also use the same Energy Sim Par/Generate EP Output components to customize the parameters of the simulation. The only effective difference between the two components is that the OpenStudio component enables the modeling of HVAC and exports the HBZones to an .osm file before converting it to an EnergyPlus .idf.
For the sake of complete clarity, we should state that OpenStudio is simply an interface for EnergyPlus and, as such, the same calculation engine is under the hood of both the Export to OpenStudio component and the Run Energy Simulation component. At present, you should get matching energy simulation results between the Run Energy Simulation component and a run of the same zones with the OpenStudio component (using an ideal air system HVAC).
All of this is to say that you should convert your GH definitions that use the Run Energy Simulation component to have the OpenStudio component and this release is the best time to do it (while the two components are supported equally). Additionally, with this version of Honeybee you will no longer need to install EnergyPlus before using Honeybee and you will only need to install OpenStudio (which includes EnergyPlus in the install).
3 - New Schedule Generation Components
Thanks to the efforts of Antonello Di Nunzio, we now have 2 new components that ease the creation of schedule-generation in Honeybee. The new components make use of the native Grasshopper “Gener Pool” component to give a set of sliders for each hour of the day. Additionally, Antonello has included an annual schedule component that contains a dictionary of all holidays of every nearly every nation (phew!). Finally, this annual schedule component can output schedules in the text format recognized by EnergyPlus, which allows them to be written directly into the IDF instead of a separate CSV file. This will significantly reduce the size of files needed to run simulations and can even reduce the number of components on your canvas that are needed to add custom schedules. For more information, see Antonello’s explanatory images here and Antonello's example file here. You can also see a full example file of how to apply the schedules to energy simulations here.
4 - EnergyPlus Lookup Folder, Re-run OSM/IDF, and Read Result Dictionary
With the new capabilities of OpenStudio, we have also added a number of components to assist with managing all of the files that you get from the simulation. In particular, Abraham Yezioro has added a Lookup EnergyPlus Folder component that functions very similarly to the Lookup Daylight Folder component. This way, you can run an Energy simulation once and explore the results separately. Furthermore, we have added components to Re-Run OpenStudio .osm files or EnergyPlus .idf files within Grasshopper. These components are particularly useful if you edit these .osm or .idf files outside of Honeybee and want to re-run them to analyze their results in Grasshopper. Lastly, a component has been added to parse the .rdd (or Result Data Dictionary) file that EnergyPlus produces, enabling you to see all of the possible outputs that you can request from a given simulation.
5 - Electric Lighting Components Out of WIP
After Sarith Subramaniam’s initial components to model electric lights with Radiance in the last release, we are happy to report that they have been fully tested and are out of WIP. Improvements include support for all types of light fixture geometries and the ability to use the components in a more “Grasshoppery” list-like fashion. See Sarith’s original release post for more information and several example files showing how to use the components can be found here. 1 , 2 , 3 .
6 - Improvements to THERM Components
A number of bug fixes and improvements have been made to the THERM components in order to make their application more flexible and smooth. Special thanks is due to Derin Yilmaz , Mel King , Farnaz , Ben (@benmo1) , and Abraham Yezioro for all of the great feedback in the process of improving these components.
7 - HBObject Transform Components
After some demand for components that can ease the generation of buildings with modular zone types, two components to transform HBObjects with all of their properties have been added to the 00 | Honeybee section. The components allow you to produce copies of zones that are translated or rotated from the original position.
8 - Comfort Maps Supports PET and Integration of CFD Results
Thanks to the addition of the ‘Physiological Equivalent Temperature’ (PET) component by Djordje Spasic in the last stable release, it is now possible to make comfort maps of PET with Honeybee. PET is particularly helpful for evaluating OUTDOOR comfort with detailed wind fields at a high spatial resolution. As such, the new PET recipe has also been optimized for integration with CFD results. The windSpeed_ input can now accept the file path to a .csv file that is organized with 8760 values in each column and a number of columns that correspond to the number of test points. Components to generate this csv from Butterfly CFD results will be coming in later releases. Stay tuned!
As always let us know your comments and suggestions.
Enjoy!Ladybug Analysis Tools Development Team
…
Analysis Tools (LAT). Our plugin has come a long way in the last 4 years and, while the legacy version will still include some small updates and contributions, we are confident in saying that the changes will be far fewer and the plugin more stable in the following months as we switch gears into the LAT effort. I can say personally that (save for a couple of small capabilities) I have made it through my list of critical features and I will hereafter be working on making these features cross-platform, cleanly-implemented, and well-documented in the new Ladybug Analysis Tools software package. As always, you can download the new release from Food4Rhino. Make sure to remove the older version of Ladybug and Honeybee and update your scripts.
The majority of changes with this release represent “icing on the cake” after a long, multi-year effort to connect to the major open source engines and datasets. So, without further adieu, here is the list of the new capabilities added with this release:
LADYBUG
Stereographic Sky Projections - Thanks to several code contributions from Byron Mardas, all Ladybug sky visualizations now support stereographic projections! Such projections are useful for understanding the hemispherical visualizations in a 2D format and they also make it easier to overlay different sky datasets on top of one another. Check here for an example file showing the sun path overlaid with helpful/harmful parts of the sky and see here for an example file using shading masks representing strategies (like an overhang) on top of the helpful / harmful portions of the sun path.
Wind Rose Upgrades - Devang Chauhan has added several new features to the Ladybug wind rose including both visual and numerical outputs of average wind velocity and frequency for each petal of the rose. Not only does this enhance the usefulness of the rose but it also paves the way for the use of the wind rose to set up CFD simulations once Butterfly is released in the near future. The new features of the wind rose can be seen in this hydra example file.
Complete Set of Local Thermal Discomfort Models - After the last release included components to evaluate radiant asymmetry discomfort (which can be modeled using these example files: 1, 2), today’s release completes Ladybug’s suite of local discomfort models from ASHRAE and the ISO by adding components to account for discomfort from cold draft. Specifically, two draft models have been added for different types of situations. The first is an older model published by P.O. Fanger, which was developed through experiments where subjects had cold air blown on the back of their neck (the most sensitive part of the body to draft). While this is useful for understanding a worst-case scenario, it can greatly overestimate the discomfort for cases of draft at ankle level - a more common occurrence that typically results from the tendency of cold air to sink. For this situation, a second draft discomfort model has been included, which is specifically meant to forecast ankle draft discomfort. The model is currently undergoing review for integration into ASHRAE-55 and a publication outlining the derivation of this model can be found here:
Liu, S., Schiavon, S., Kabanshi, A. and Nazaroff, W. (2016), Predicted Percentage Dissatisfied with Ankle Draft. Indoor Air. Accepted Author Manuscript. doi:10.1111/ina.12364 (http://escholarship.org/uc/item/9076254n).
Special thanks is due to Shichao Liu, Toby Cheung and Stefano Schiavon for sharing the model and the results of their study with the development team. The integration of draft models completes the full integration of ASHRAE-55 and EN-15251 with Ladybug. Now, you can rest assured that, if there is a certain thermal comfort standard that you need to fulfill for a given project, you can model it with the ‘bug!
Window-Based Draft Model - With the integration of draft models, the first question that one might ask is “how should these models be applied to typical design cases?” While the (soon-to-be-released) Butterfly plugin for OpenFOAM should open up a Pandora’s box of possible situations, this release of Ladybug includes a simplified downdraft model from cold vertical surfaces, which helps model several typical cases of draft discomfort. The model has been validated across several papers:
Heiselberg, P. (1994). Draught Risk From Cold Vertical Surfaces. Building and Environment, Vol 29, No. 3, 297-301
Manz, H. and Frank, T. (2003). Analysis of Thermal Comfort near Cold Vertical Surfaces by Means of Computational Fluid Dynamics. Indoor Built Environment. 13: 233-242
It has been built into the “Ladybug_Downdraft Velocity” component and has been included in an example file illustrating discomfort from cold windows in winter. The example is intended to show when glazing ratio and window U-Values are small enough to eliminate perimeter heating - a practice that is aesthetically unpleasing, costly to maintain and wasteful in its energy use.
Operative Temperature on the Psychrometric Chart - This is a feature that should have been added a long time ago but we are finally happy to say that the Ladybug_Psychrometric Chart can draw a comfort polygon assuming that the air temperature and radiant temperature are the same value (aka. an operative temperature psychrometric chart). This operative temperature chart is the format that is needed to use the ASHRAE-55 graphical method and is generally a better representation of the range of comfort in cases where one does not intend to hold the radiant temperature constant. This operative temperature capability is now set as the default on the component but you can, of course, still bring back the older comfort polygon by simply plugging in a value for meanRadiantTemperature_.
Contour Map Visualizations - Using the same inputs as the Ladybug_Recolor Mesh component, the new Ladybug_Contour Mesh component allows you to generate contoured color graphics from the results of any analysis. Now, you to maximize the use of your high-resolution studies with contours that highlight thresholds and gradients!
Image Texture Mapping for Colored Meshes - Antonello DiNunzio has added the very useful Ladybug_Texture Maker component, which allows you to bake Ladybug colored meshes with image texture maps (as opposed to the classic method that used colored vertices). This enables the creation of transparent Ladybug meshes, making it even easier to overlay Ladybug graphics with one another and with Rhino geometry:
This component also adds the ability to render Ladybug + Honeybee meshes with other rendering programs like V-Ray and 3ds Max. So you can produce Ladybug graphics like this!
Finally, image-mapped textures are also the format required for gaming and Virtual Reality software like Unity and Augmented Reality programs like Augment. So now you can export your Ladybug meshes all of the way to the virtual world!
Rhino Sun Component - If you have ever had to set up the sun for a rendering plugin and wished that you could just take your Ladybug sun and use that, then you are in luck! Byron Mardas has contributed a component that lets you set the Rhino sun based on your EPW location data, your north direction (if different from the Y-Axis) and any time of day that you want. Not only does this make it easier to coordinate the Rhino sun with your Ladybug visualizations, but you can also use it for real time shadow previews by setting your Rhino view to “Rendered” and scrolling through a slider.
Rendered Ladybug Animations - With both the image texture mapping and the Rhino sun components released, your first thought might be “it would be great if I could use this all in a rendered animation!” Thankfully, Ladybug has added a new component to help you here. The Ladybug_Render View component works in essentially the same way as the Capture View component, allowing you to make a series of images as you animate through a slider. The major benefit here is that it works with both Rhino Render and V-Ray so that animations like this can be produced effortlessly:
Cone of Vision Added - Antonello Di Nunzio has added a component that allows you to visualize various cones of vision in order to help inform your view studies. You can fine tune parameters to include just text-readable or full peripheral vision and use the resulting view cone to constrict the results of your “Ladybug_View Analysis” studies.
Terrain WIP Components Released as the Gismo Plugin - Our friend Djordje has released a new plugin Gismo - a plugin for GIS environmental analysis. As a result the following 5 terrain components: Horizon Angles, Flow Paths, Terrain Shading Mask, Terrain Generator 2, Terrain Analysis, have been removed from Ladybug+Honeybee's WIP section and are added to Gismo.
HONEYBEE
Search, Select, and Import the Hundreds Outputs from EnergyPlus/OpenStudio - Many of the power users in our community know that EnergyPlus is capable of writing several hundred different outputs from the simulation (well beyond what the basic Honeybee result readers can import). While Honeybee has always allowed one to request these outputs by adding them to the simulationOutputs_ of the component, there has not been an official workflow for searching through all of the possible outputs or importing their specific results… until now! We have added the "Honeybee_Read Result Dictionary" component, which allows you to parse the Result Data Dictionary (or .rrd file) that EnergyPlus outputs during every run of a given model. This allows you to see all of the outputs that are available for the model and you can even search through this list to find a particular output that you are interested in. Once you find what you are looking for, simply copy the text output from the component into a panel and and plug this into simulationOutputs_. Then you can use the "Honeybee_Read EP Custom Result" component to bring your custom results into GH after rerunning the simulation. The example file of an evaporative cooling tower shows how to use the workflow to request and import in the energy removed by the tower.
OpenStudio HVAC System Sizing Results - After the full integration of HVAC in the last release, we realized that a number of people wanted to run EnergyPlus models simply to evaluate the size of the Heating/Cooling system in the model (obtained from the EnergyPlus autosize calculation that is run at the start of every simulation). Such a sizing calculation can be a great way to quantify the anticipated savings from a given strategy (like shading) on the size/cost of the building’s HVAC system. To get the results of the sizing calculation, all that one needs to do is connect the output eioFile from the OpenStudio component to the Honeybee_Read HVAC Sizing component. The outputs will indicate the peak heating/cooling loads of each zone (in Watts) as well as the size of each piece of HVAC equipment in the model. The next time that you are on a project that is about to value-engineer out an exterior shading system, use the workflow in the following example file to show that the client will probably end up paying for it with a more expensive HVAC system: Quantifying HVAC Sizing Impact of Shade.
Improved Memory Usage When Building Large Energy Models - As we take the capabilities of Honeybee to larger and larger models, many of us have begun to run up against a particular limitation of our machines: memory. After upgrading our machines to have 32 GBs of RAM, there was only one way left to alleviate the problem: restructure some of the code. Honeybee now uses an enhanced approach that ensures all the previous iterations of Honeybee objects will be removed from the memory once there is a change. In any case, the considerations of memory are definitely something that we intend to improve with the future Honeybee[+] plugin.
Workflow to Import gbXML Files - While GrizzlyBear has been around for several years, enabling us to export Honeybee zones to gbXML, we have gone for quite some time without a workflow to import gbXML files to Honeybee. The new Honeybee_gbXML to Honeybee component addresses this and establishes an easier path to import models from Revit into honeybee. You can read more about the component in this post.
Window Frame Capabilities Added to OpenStudio - After the implementation of LBNL THERM / WINDOW capabilities in the last two releases, there was one final bridge to build in the Honeybee workflow - fully connecting LBNL WINDOW to Honeybee’s OpenStudio workflow. This release of Honeybee will now write all FrameAndDivider objects exported from LBNL WINDOW glazing systems into the energy simulation, enabling you to account for the frame’s thermal bridging effects. As long as the construction is brought in with the Honeybee_Import WINDOW IDF Report component, the frames associated with the construction will be assigned to all windows that have the construction. Finally, it is worth noting that the current Honeybee will also write all glass spectral data as well as gas (or gas mixture) materials into the simulation. This means that essentially all properties of any IDF export that one makes from LBNL WINDOW can be factored into the OpenStudio energy simulation (with the only exception being BSDF materials).
OpenStudio Daylight Sensors Added - In our previous releases of Honeybee, the only means of correctly account for daylight sensors in an energy simulation was to run an annual daylight simulation and use the resulting schedules for the lighting in the energy simulation. However, this can take a lot of time and work to set up and run, particularly if the daylight control (at the end of the day) will be driven by just one sensor per room. Now, we have added another option, which uses OpenStudio/EnergyPlus’s built-in daylight controls. You can assign just a point and an illuminance target on the “Set Zone Thresholds” component and the lighting will be automatically adjusted in the course of the simulation. It should also be noted that the addition of daylight sensors has also coincided with the addition of blind/shade control based on glare. The same sensor point for daylight can be used to drive dynamic shades in the energy simulation based on glare experienced at this point. This example file shows how to set up daylight controls on the EnergyPlus model and check the lighting power results to see the effect.
Better Defaults for Natural Ventilation - After many good people wrote to me informing me that Honeybee overestimates natural ventilation airflow and I wrote back showing the way that I intended natural ventilation to be set up with the component, it dawned on me that I had selected some poor component defaults. Accordingly, this release includes a window-based natural ventilation option on the Set EP Airflow component that corrects for some of the common issues that I have seen. Insect screens are included by default and the component runs a general check to see if wind-driven cross ventilation is possible before auto-assigning it. The component will air on the side of more-conservative, lower airflow rates unless the user overrides the defaults. Finally, it’s worth noting that all of these changes have not affected the freedom of the Custom WindAndStack option on the component. The new defaults can be viewed in this example file.
CFD Results Can be Plugged into Microclimate Maps - In preparation for the (very soon) release of the Butterfly that connects to the OpenFOAM CFD platform, we just wanted to note that all of the microclimate map recipes can now take an input of a csv file with a matrix of CFD results for wind speed. For the time being, we have used these to produce very high-accuracy, high resolution maps of outdoor comfort. There will be more to follow soon!
We should also note that, in the last release I mentioned that we would be phasing out the EnergyPlus component so that all efforts are focused on the OpenStudio component. While I reiterate that all of the features of the EnergyPlus component are available in the OpenStudio component and I encourage everyone to use the OpenStudio component in order to take advantage of its HVAC capabilities, I have come to realize that many prefer to use the EnergyPlus component out of habit and have not yet gotten the time to understand why the OpenStudio component is an improvement over the EnergyPlus component. As a result, we have decided to leave the EnergyPlus component in place for the time being so that everyone has more time to understand this. The future Ladybug Analysis Tools platform will only interact with EnergyPlus through OpenStudio and so it is recommended that everyone use these two components in the Honeybee plugin will serve as an educational resource to understand our current path moving forward with OpenStudio.
Lastly, it is with great pleasure that we welcome Devang Chauhan and Byron Mardas to the developer team! As mentioned previously Devang has contributed several updates to the Ladybug Wind Rose in addition to finding and solving a multitude of bugs in other components. Byron has contributed code that has enabled the previously-mentioned stereographic sky projections along with a better method for running the Ladybug Sky Mask. Finally, Byron has contributed the Rhino Sun component, which allows you to coordinate your Rhino renders with your Ladybug data. Welcome to the Ladybug team, gentlemen!
As always let us know your comments and suggestions. Cheers!
