ATG graph

An “ATG Chart” contains thermal comfort points as a function of the mean outside air temperature of the last three days. This Dutch standard is meant to give extra dimensions to the “GTO” method. The PMV method is useable for thermal comfort situations with extremely high metabolisms or clothing values. An ATG can be used for buildings with great or small user influence, and can be used for buildings with open or enclosed facades.

Room Number

Defines from which room the data will be sued to generate the ATG graph

Period

Defines the period over which the ATG graph will be displayed

•      The Total period is over the total period for which you have calculated. This period is defined by the selection of the Climate File.

•      The Usage Period displays only the period of time when the building is in use. Defined in the Climate File, and linked to the areas Schedule of IHG viewed over the entire building.

Temperature

 Specifies on what temperatures the ATG graph should be based.

•      Comfort temperature. Displays the results based on the comfort temperature for the room.

•      Air temperature. Displays the results based on the aur temperature for the room

Alpha / Beta

Specifies whether the ATG graph should be displayed according to alpha or beta guidelines

•      Alpha. Building / climate type Alpha

•      Beta. Building / climate type Beta

Graph / timesheets

Here you specify whether to display the ATG results as a graph or as a table.

•      Chart. Displays the ATG graph.

•      Timesheet. Provides an overview per hour in tabular form.

Underheating hours / Overheating hours

This selection controls what you want to show in the table, the underheating hours, or the overheating hours.

65% 80% 90%

The three percentages refer to the three building classes:

•      90% - Class A building, where 90% of the users accepts the indoor climate;

•      80% - Class B building, where 80% of the users accepts the indoor climate;

•      65% - Class C building, where 65% of the users accepts the indoor climate.
