Ladybug.0.0.65

Better Method for Updating Old Grasshopper Files - As many of you have come to realize, Ladybug + Honeybee is updated on a fairly regular basis, with a stable release roughly every 6 months and a github version that never ceases to improve itself on a weekly basis. For this reason, we realize that updating old Grasshopper definitions to use recent components is a challenge for many of us. While we’ve had some methods for this in the past, there were always hiccups, particularly when it came to components that had new inputs/outputs since the previous version. Accordingly, Mostapha has added a new “Ladybug_Update File” component that will automatically update any Grasshopper Definition to be synchronized with the version of Ladybug+Honeybee that is currently in your toolbar (aka. the components in your userobjects folder). If there is a component that has new inputs/outputs since the time you built the definition, it will be automatically circled in red in your GH definition and a newer version of the component will be automatically added right next to this component:

While you still have to do some manual connecting of inputs to the newer component in this case, it should be much faster than our older methods and will hopefully help your old definitions survive long into the future!

EPWmap Now includes OneBuilding Files - Mostapha has added a number of new features to the EPWmap web interface that the “Download Ladybug” component connects to. Among the improvements are a color wheel that quickly shows you how hot, cold, and comfortable a given climate is and, perhaps more importantly, there is now support for EPW files sourced from OneBuilding. With the addition of many more weather files, you should now be able to use Ladybug with ease for more locations across the planet. We should also note that the “Open EPW and STAT” component that downloads/unzips files from a URL now supports OneBuilding URLs.

New Image Viewer Component - Mingbo Peng has graced Ladybug with a fantastic new “Image Viewer” component that takes a given image file on one’s machine and displays it on the Grasshopper canvas. It also enables one to pull color data off of the image with ease by simply clicking on the pixel of the image one is interested in. This new component is useful for a wide variety of cases, including the viewing of screenshots after they have been taken with the “Ladybug_Capture View” or “Ladybug_Render View” components. However, many of you will likely recognize it as most immediately useful in workflows involving image-based Honeybee Daylight (Radiance) simulations. This is particularly true as Migbo has built-in the capability to read many image file types, including PNG, JPEG, GIF, TIFF and the High Dynamic Range (.HDR) image files that Radiance Outputs:

The new component can be found under the Ladybug_Extra tab and I think I speak for us all in saying thank you Mingbo for this great component!

New Sun Shades Calculator Released Under WIP - After over a year of software development and nearly a career's worth of geometric math development, a joint effort between Abraham Yezioro and Antonello Di Nunzio has produced a new sun shade design component that can be described as nothing short of “magical.” Based on a similar principle to the current “Ladybug_Shading Designer,” the new component takes an input of sun vectors and produces shade geometries that can block the vectors. However, in comparison to the shading designer, the range of shade options that are available in this new component is truly staggering, ranging from classic overhangs, louvers and fins to pergolas and custom shade surfaces. Perhaps more importantly, the calculation methods used by this new component are faster and more reliable. It can currently can be found under the WIP section of Ladybug and it will continue to evolve in new versions of Ladybug.

Renewable Component Now Support Sandia and CEC Photovoltaics Modules - Polishing off his many contributions to the “Renewables” section of Ladybug, Djordje Spasic has added support for a couple more ways of defining Photovoltaic modules for renewables estimation. Specifically, the Ladybug WIP section now includes components to import modules defined with the California Energy Commission (CEC) and Sandia Labs.
