Buildings.Controls.OBC.Shade.Shade_H
Shade controller with solar irradiation as input
Information
Block that outputs a shade control signal y ∈ {0, 1} as follows:
- When
y=0
and the inputH
becomes greater than the parameterHHigh
, the output switches toy=1
. - When
y=1
and the inputH
becomes less than the parameterHLow
, the output switches toy=0
.
Parameters
Type | Name | Default | Description |
---|---|---|---|
Real | HHigh | if y=0 and H>=HHigh, switch to y=1 [W/m2] | |
Real | HLow | if y=1 and H<=HLow, switch to y=0 [W/m2] |
Connectors
Type | Name | Description |
---|---|---|
input RealInput | H | Measured irradiation [W/m2] |
output RealOutput | y | Control signal [1] |

Buildings.Controls.OBC.Shade.Shade_T
Shade controller with temperature as input
Information
Block that outputs a shade control signal y ∈ {0, 1} as follows:
- When
y=0
and the inputT
becomes greater than the parameterTHigh
, the output switches toy=1
. - When
y=1
and the inputT
becomes less than the parameterTLow
, the output switches toy=0
.
