Details on Location and Climate Data
Information about the Location and climate data section of the general heat load data.
You are here:
Location...
Opens the Locations dialog, where you can choose a location for your project.
The locations of the respective region are available for selection in alphabetical order. When selecting a location, the fields Standard outside temperature, Height local selection above sea level and Annual average temperature are filled with values from the standard. The standard outside temperature results from the design outside temperature, which is adjusted with a temperature correction and/or a height correction factor, if necessary.
For the calculation base Belgium NBN 12831-1 ANB (2020) the height specifications are omitted as they are irrelevant for the calculation. From the Belgian climate data, the Minimum temperature is displayed for the currently selected location. An increase of the default values is not provided for in this supplement.
If you have selected the calculation basis Europe: EN 12831-1 (2017)you can also manually enter the values standard outside temperature, height location selection or height location and annual average temperature for locations outside Germany.
Temperature correction (Time constant)
Enabled: Depending on the selected building mass and the transmission losses of the building, a correction is applied to the outside temperature. The corrected value is displayed in the Standard outside temperature field.
Height meteorological station above sea level
The height of the meteorological station is part of the location data and is only entered if the selected location contains the corresponding data. This value takes no part in the calculation and can be understood as additional information or used to check the plausibility of the height of the building above sea level.
Height local selection above sea level
Height of the selected location above sea level. The value is part of the location data and cannot be changed.
Locations absolute altitude
Enter the exact location height of your project here. When a location is selected, the altitude of the location is automatically set to the altitude of the location selection. From 200 m difference to the height of the selected location, a height correction is calculated with the standard outside temperature.
(Standard) Outside temperature
This temperature is suggested according to the selected location from the building data. If the temperature correction is activated, the possibly corrected value is displayed here.
Annual average temperature
Annual average temperature is part of the location data and cannot be changed.
Inside temperatures according to standard
Enabled: Overwrites the indoor room temperatures for the heating case with the temperatures from the standard, depending on the selected room type. In the room view of the heat load, a tooltip appears above the input field of the room temperature with the note Room temperature corresponding to selected standard. Additionally, the option Increase of default values is enabled.
Disabled: Room temperatures can be entered manually. If the values entered correspond to the specifications in the standard, a tooltip appears above the input field for the room temperature with the note Room temperature corresponding to the selected standard. If the values entered do not comply with the standard, the note Room temperature is freely agreed appears at this point.
Increase of default values
Enabled: Activates the corresponding text field, in which the room-specific standard inside temperature can be manually increased by up to 3 K. In the result window and in the printout, besides the result of the calculation with the standard inside temperatures, the capacity overhead (difference from heat load with and without temperature increase) is listed additionally. The capacity overhead due to temperature is compared with the heating supplement from the intermittent heating operation. The higher value of the two is taken into account in the heat load.
