class ladybug_comfort.chart.adaptive.AdaptiveChart(outdoor_temperature, operative_temperature, air_speed=None, comfort_parameter=None, legend_parameters=None, base_point=Point2D(0.00, 0.00), x_dim=1, y_dim=1, min_prevailing=10, max_prevailing=33, min_operative=14, max_operative=40, use_ip=False)[source]

Bases: object

Adaptive comfort DataCollection object.

Parameters:

  • outdoor_temperature –

    Either one of the following inputs are acceptable:

    • A Data Collection of prevailing outdoor temperature values in C. Such a Data Collection must align with the operative_temperature input and bear the PrevailingOutdoorTemperature data type in its header.

    • A single prevailing outdoor temperature value in C to be used for all of the operative_temperature inputs below.

    • A Data Collection of actual outdoor temperatures recorded over the entire year. This Data Collection must be continuous and must either be an Hourly Collection or Daily Collection. In the event that the input comfort_parameter has a prevailing_temperature_method of ‘Monthly’, Monthly collections are also acceptable here. Note that, because an annual input is required, this input collection does not have to align with the operative_temperature input.

  • operative_temperature – Data Collection of operative temperature (To) values in degrees Celsius.

  • air_speed – A number for the air speed values in m/s. If None, a low air speed of 0.1 m/s wil be used. (Default: None).

  • comfort_parameter – Optional AdaptiveParameter object to specify parameters under which conditions are considered acceptable. If None, default will assume ASHRAE-55 criteria.

  • legend_parameters – An optional LegendParameter object to change the display of the AdaptiveChart. (Default: None).

  • base_point – A Point2D to be used as a starting point to generate the geometry of the plot. (Default: (0, 0)).

  • x_dim – A number to set the X dimension of each degree of temperature on the chart. (Default: 1).

  • y_dim – A number to set the Y dimension of each degree of temperature on the chart. (Default: 1). Note that most maximum humidity ratios are around 0.03. (Default: 1500).

  • min_prevailing – An integer for the minimum prevailing temperature on the chart in degrees. This should be celsius if use_ip is False and fahrenheit if use_ip is True. (Default: 10; suitable for celsius).

  • max_prevailing – An integer for the maximum prevailing temperature on the chart in degrees. This should be celsius if use_ip is False and fahrenheit if use_ip is True. (Default: 33; suitable for celsius).

  • min_operative – An integer for the minimum indoor operative temperature on the chart in degrees. This should be celsius if use_ip is False and fahrenheit if use_ip is True. (Default: 14; suitable for celsius).

  • max_operative – An integer for the maximum indoor operative temperature on the chart in degrees. This should be celsius if use_ip is False and fahrenheit if use_ip is True. (Default: 40; suitable for celsius).

  • use_ip – Boolean to note whether temperature values should be plotted in Fahrenheit instead of Celsius. (Default: False).
