This is the release 0.0.58 of Honeybee. Major changes are listed below:

  1. Fully Functional Microclimate Maps - Finally, after a long and arduous thesis followed by a couple of months of bug-fixing, Chris Mackey is pleased to announce that the ability to produce high resolution temperature maps from EnergyPlus results is complete. Together, these maps account for four key variables that produce microclimatic diversity in and around buildings - MRT variation from different surface temperatures, solar radiation shining directly on occupants, average air temperature diversity, and air temperature stratification. In addition to using these 4 variables to produce high-resolution visuals of temperature, it is also possible to produce maps of thermal comfort by using any of the three primary thermal comfort models in Ladybug (PMV, Adaptive, and Outdoor (UTCI)). Support currently exists to produce maps for both indoor and outdoor conditions and, while the temperature values and indoor comfort values currently produced are highly accurate, the outdoor wind speeds are calculated using the simplified assumptions of EnergyPlus and will be revised to enable more accurate accounting for the effects of wind on outdoor comfort in the next stable release. The whole workflow is broken down into eight components that can all be found under the 9 | Energy Energy tab. For some videos showing some time-lapse thermal renderings made from these tools see this video playlist:

    Finally, if you want to dive in and produce some comfort maps for yourself, you can find an example file here for indoor maps:

    And an example file here for outdoor maps:

  2. Thermal Autonomy / Thermal Comfort Percent - In addition to the new thermal mapping capabilities, this release includes the ability to use these maps to calculate a series of spatial thermal comfort metrics that are meant to mirror the metrics currently used to evaluate daylight (daylight autonomy, UDI, etc.). Specifically, these metrics are the following:
    Thermal Comfort Percent - The percentage of occupied time that a given point in space is thermally comfortable.
    Thermal Autonomy - The percentage of occupied time that a given point in space is thermally comfortable without the addition of any heating or cooling energy.
    Overheated Hours - The percentage of occupied time when a given point is space is too hot to be thermally comfortable.
    Underheated Hours - The percentage of occupied time when a given point is space is too cold to be thermally comfortable.
    All of these metrics can be accessed through the “Thermal Autonomy Analysis” component and you can find an example file here:
  3. Energy Balance Visualizations - In order to help understand the flow of energy through Honeybee energy models, it is now possible to completely reconstruct the energy balance calculation of EnergyPlus from the energy simulation results. This is facilitated by the new EnergyPlus “Construct Energy Balance” component and some new features added to the monthly bar chart. See here for an example:

  4. More Geometry Control for Glazing - In order to make it faster to assign several different types of glazing geometries to your energy models, the “AddHBGlz” can now be used to add glazing surfaces to HBzones (not just HBsurfaces). Furthermore, the “Glazing Based on Ratio” component now contains several more inputs that enable you to customize window geometry on orthogonal surfaces, including the ability to set the horizontal distance between windows and the ability to split windows vertically into a lower view window and higher daylight window.
  5. Earth Tube Capability - Thanks to the efforts of Anton Szilasi, it is now possible to assign earth tubes to your energy models in order to test the potential of this powerful passive strategy. See here for an example file:
  6. North Input For Annual Daylight - After the toil of having to rotate your model any time you wanted to run an annual daylight analysis, we are happy to announce that the annual daylight recipe now contains a working “North” input.
  7. Honeybee Objects Transformation - After realizing that many of us wanted to construct energy models of multi-story buildings by duplicating and moving zones, this capability is now easily facilitated with a set of three components to duplicate and transform your HBObjects. Specifically, this includes a component to move (translate) your HBObject, mirror (reflect) your HBObject, and rotate your HBObject. Using these components ensures that any properties that you have assigned to your original HBObject will be present in the transformed HBOjbect, allowing you to build large energy models very quickly. The three components can currently be found under the WIP tab. See here for an example file:
