Advanced Course Controls (CTRL 1,2,3)

A selection of exercises, from which you can choose individually, will give you an insight into the many possibilities for modelling every conceivable building control system.

Requirements
Course participants are expected to have attended at least one continuation course.

In the 3 course days we work out:

• debugging
• Functionality testing
• Getting to know all control levels including their cross-dependencies
• Getting to know the most common controllers and their typical applications

• Exercise 1: Shading Control

  In this exercise, we create a control strategy for the integrated sunshade. Here, illuminance at desk level is kept below 700 lx. The control is then extended to include a few more targets. The exercise also explains how a thermostat dead band works.

• • Exercise 2: Adaptive Lighting Control

This exercise is a continuation of the first exercise. Here, a brightness control is added that switches the light on or off depending on the illuminance of the workspace.

• • Exercise 3: Cross-dependencies of controlled variables and adaptive setpoints

When a window in a zone is opened, the ventilation and heating of the zone are usually switched off to save energy. In this exercise we will create such a control for a zone. The control works by changing the cooling and heating setpoints and the ventilation signal when a window is open.

• • Exercise 4: Measured variables from the advanced level

A simple dew point control for the supply temperature prevents condensation on the cooling sail.

• • Exercise 5: Step control

Some systems are controlled incrementally rather than as continuous. In this exercise we create such a control scheme for zone ventilation.

• • Exercise 6: Comfort fields

In this exercise, we create a control macro that keeps the indoor air temperature within the limits of a comfort field that depends on the outdoor temperature.

• • Exercise 7: Centralised air volume control
    

In this exercise we will create a control for a branch of a ventilation unit that serves three classrooms. The ventilation is controlled from the branch root and the airflow is the same for all rooms. The airflow control measures the CO2 concentration at the ventilation control damper and tries to keep the concentration in each room below 900 ppm.

• • Exercise 8: Several local units

In this exercise we will create a control for two heaters in a bathroom. The bathroom has underfloor heating that tries to keep the floor temperature at 26 ̊C and a radiator that keeps the air temperature above 22 ̊C in the zone.

• • Exercise 9: Temperature and CO2 ventilation via windows/openings

In this exercise we will create a control for smoke and heat exhaust ventilation to avoid overheating in large spaces such as atriums. At the top and bottom of an atrium are windows that are opened when cooling is needed in the atrium and potential in the outside air.

• • Exercise 10: Control of a mixing box in the central ventilation unit

Many larger ventilation units have a recirculation unit, where some of the exhaust air from the building is mixed with fresh air and reused as supply air. Recirculation control is one of the more demanding systems because there are two conflicting requirements for the air. On the one hand, the air quality must not fall below certain limits, but on the other hand we want to save as much heating energy as possible. The recirculation system also has the advantage of transferring moisture, which has a positive effect on air quality in cold climates. In this exercise, a control scheme for the recirculation unit is created. The control limits the CO2 concentration in the extract air to 800 ppm and tries to keep the supply air temperature above 18 ̊C.

• • Exercise 11:

It is often necessary to start the heating or ventilation in a hotel or meeting room or to change the room setpoints before people enter the room. This exercise shows how to use the "time before use" signal.
