Schedules in QBRX are not only a simple source of information. They can also be used in analysis.

In this article, we'll be talking about the creation of evaluation rules in QUDE and how to effectively use them.  

Example: load profiles during opening hours

With the help of schedules, you can analyze your data during and outside designated times. In our example, we want to design build a data point that only displays the load profile of electricity either during the opening hours of a shop. 

The load profile evaluated in this data point can be used to calculate the consumption during this specific period. Values of other data points could further be processed in the same way.

We'll use a conditional brick with further outcome for this evaluation rule. This setup will only evaluate values that fit a specific condition. Everything else will be displayed as a constant value. For this example, we'll use the opening hours as a condition. 

This means, that the condition has to be "true" and the opening hours need to be "active" to trigger the calculation of the load profile, Otherwise, QUDE will calculate the defined constant "0".

Step-by-step instruction 

1. Add the property "opening hours" to the list of usable properties

• Add the opening hours of the facility you would like to integrate into your evaluation.

   

2. Add the data point "load profile electricity" to the list of usable data points

• Add the electricity load profile of the same facility to your list.

   

3. Drag and drop all necessary bricks into the work surface and combine them

• Used bricks: One conditional with further outcome, one schedule, one for properties, one numeric data point, a constant and two results.

   

4. Choose the property and data point in the matching bricks

    

5. Choose a condition: "active" or "not active"?

• Connect theschedule brick with the "if"-line of theconditional brick and add the property brick. 

• If you would like to see all values within your opening hours, select "active"

• If you would like to see all values outside your opening hours, select "not active"

   

6. Define the outcome at "do"
• Select at "do" what should happen, if the defined condition occurs
• Combine the result brick with the numeric data point
• As a consequence, the chosen data point will be evaluated whenever the condition is "true"
   
7. Define the further outcome at "else"
   • Select at "else" what should happen, if the defined condition does not occur
   • Combine the result brick with the constant. Set the constant to "0".
   • As a consequence, the chosen data point will be evaluated if the condition does not occuris "false"
      

8. Save your settings
