Creation of adequate periods and day-profiles

Under the Tree entries Inner Loads/Occupancy, Design Conditions and HVAC it may be important to create adequate periods and day-profiles of usage of the building and building requirements.

The way to proceed is demonstrated using the example of the heating under Design Conditions

As almost no building is used the same way all week long, defining a new period or new periods is almost always reasonable. By clicking on "New" a new period, which can be varied in the designated way, is created. The lowest period is always read first, and for days or periods not defined by it, the next higher is effective. Then for every period an adequate day-profile should be created

The following example should illustrate this. The lowest period saves the information for the weekdays from January 1st to May 1st (2011). The next higher one has every day checkmarked but is only effective for weekends from January 1st to May 1st (2011), as the lowest already contains information for the weekdays. The second period therefore defines the weekdays from May 2nd 2011 to January 1st in 2012. The weekends from May 2nd 2011 to January 1st 2012 ( or generally speaking: all that has been left out by the lower periods) are defined by the information saved in the first period.

First of all the lower period is the essential one, and for days not defined by it (Saturdays and Sundays) the upper one is effective.

For this example it is assumed, that the building is used as a office from Monday to Friday, so the check marks of the lower
