Figure 1. Weekly overview with effects, net energy demand, energy savings and radiation reduction.
The stamp's number corresponds to the numbers in the summary above.

Figure 2. Moisture transport due to absolute humidity below which is higher than above the screen.
As the positive difference increases, the humid pressure difference increases. As a result the relativ humidity can drop.

Figure 3. Energy savings through screens.
The longer the screen remains (completely) closed, the bigger the energy savings.

      2. Postpone ventilation when the screen opens in the morning.

      The screen opens if solar radiation or outside temperature is sufficient. The 'screen closed' status then becomes 'screen open in progress'.
At 'screen open in progress' the ventilation temperature will be increased by two degrees, for example,
until the minimum screen position (open) is reached. Meaning vents close or remain closed, while the screen opens.

      3. If the energy savings of closed screens can't compete with the reduction of solar radiation, the screens are released to open.

      These parameters can be compared with each other to determine the right time for opening in the morning and closing in the afternoon.
The required switch data have to be found in practice. Then consult your technical partner for the necessary settings,
making use of custom alarm or uni-switch. Check also how to use a pyrgeo sensor.

 
Figure 5. The computer calculates the energy-saving rate based on the position of the screens.
A partially open screen (check red line) significantly reduces the energy saving (yellow line).
