honeybee_energy_ph.boundarycondition module¶

Extra Boundary Condition objects for Passive House models.

Note to developers:: See _extend_honeybee_energy_ph to see where these boundary conditions are added to honeybee.boundarycondition module.

class honeybee_energy_ph.boundarycondition.PhAdditionalZone(identifier: str = '', temperature: float | Autocalculate = Autocalculate, heat_transfer_coefficient: float = 0, zone_name: str = '', zone_type: str = '', temperature_reduction_factor: float = 1.0)[source]¶

Bases: OtherSideTemperature

For surfaces exposed to attached zones with different temperature settings.

This class extends the basic honeybee-energy OtherSideTemperature boundary condition by adding properties specific to Passive House modeling, such as zone-name, zone-type, and temperature-reduction-factor.

ToString()¶: Overwrite .NET ToString.

classmethod from_dict(data: dict) → PhAdditionalZone[source]¶

Initialize PhAdditionalZone BoundaryCondition from a dictionary.

Parameters:: data – A dictionary representation of the boundary condition.

to_dict() → dict[source]¶: Get the boundary condition as a dictionary.

to_idf(identifier)¶

Get the boundary condition as an IDF string.

Parameters:: identifier – Text for unique identifier to be given to the boundary condition.

property heat_transfer_coefficient¶: Get a value in W/m2-K for the combined convective/radiative film coefficient.

identifier¶

property name¶: Get the name of the boundary condition (ie. ‘Outdoors’, ‘Ground’).

property sun_exposure_idf¶: Get a text string for sun exposure, which is write-able into an IDF.

property temperature¶

Get a value in Celsius for temperature on the other side of the object.

Autocalculate signifies that the outdoor air temperature is used.

temperature_reduction_factor¶

property view_factor¶: Get the view factor to the ground.

property wind_exposure_idf¶: Get a text string for wind exposure, which is write-able into an IDF.
