Result types (Heat Overlay)
Revision as of 12:55, 11 September 2019 by Frank@tygron.nl (talk | contribs)
The Heat Module of a Heat Overlay performs complex calculations and can generate multiple types of results per timeframe. A timeframe in the Heat Overlay correspond to a date and time for which a result will be calculated. This date and time will be relative to the project's time zone.
List of Result Types
Icon | Result type | Unit | Display mode | Description |
---|---|---|---|---|
BOWEN_RATIO | Date-Time | The initial bowen ratio of buildings and terrain. Differs for water terrain based on day and night. | ||
FOLIAGE | m | Start | The initial and optional calculated foliage height, depending on the source of the foliage height. | |
PET | °C | Date-Time | The calculated physiological equivalent temperature. | |
PET_RELATIVE | °C | Date-Time | The calculated PET temperature subtracted by the calculated atmospheric temperature | |
SHADE | Date-Time | Indicates whether a cell is in the shade or not based on sun ray calculations. | ||
SKY_VIEW | Start | The calculated sky view factor. | ||
SKY_VIEW_AVG | Start | The calculated average of individual calculated sky view factors. | ||
TEMPERATURE_ATMOSPHERE | °C | Date-Time | The calculated atmospheric temperature, based on the UHI, sun motion factor and the measured temperature. | |
UHI | °C | Date-Time | The calculated urban heat island effect. | |
VEGETATION | Date-Time | The fraction of vegetation per square meter. | ||
VEGETATION_AVG | Date-Time | The calculated average vegetation based on the cells' individual vegetation fraction. | ||
WIND_SPEED | m/s | Date-Time | The wind speed calculated for the height of 1.2 meters above ground. |
Result types can differ in the kind of data they display, the layer (surface or underground) of which they display that information, and how that data is recorded. Different result types can monitor data in the following ways:
- Start: The data is determined at the start of the simulation, and does not change afterwards.
- Date-Time: The data is dependent on the timestep, which corresponds to a date and time. In case the Average timeframe option is selected, the last timeframe will present the average values of all previous timesteps for that particular Result Type.
