Tailored to your project: NETx Shutter Control
For the automatic shading of complex buildings, high user comfort and energy efficiency are of utmost importance. To reach these ambiguous goals, NETx Shutter Control was developed. NETx Shutter Control is a software for automatic shading of complex buildings. It controls blinds considering the current season, weather, sun position as well as the position and 3D geometry of the building.
NETx Shutter Control is based on a 3D model, which considers your building but also the sun path and the shadow of the surrounding objects. In combination with live data e.g. weather and position of the sun, the blinds are controlled in an optimum way. Being a project-specific solution, NETx Shutter Control always considers your individual needs as well as special operating modes.
The use of ordinary sensors and actuators is not sufficient for sophisticated shading solutions. The resulting shadow of surrounding objects and building parts cannot be recognized by such simple devices. Complex algorithms and control logic need computational resources that cannot be provided by embedded devices. Therefore, it is necessary to use a software at the management level of the building automation system.
NETx Shutter Control is a solution which was developed for large and complex buildings. In combination with the NETx BMS Server, you can control and visualize thousands of blinds in a central way.
Located at the management level, NETx Shutter Control is a client which is connected to the NETx BMS Server. Via this connection NETx Shutter Control receives sensor values like the current weather situation and the status of the blinds, and sends control commands for changing the blinds and slats. Other control commands like maintenance mode and manual/automatic control are provided by NETx Shutter Control system. NETx Shutter Control consists of a server component and the management GUI. The server is the main part of the system. It is responsible for the overall control functionality. The manager GUI is the management interface of the server. It is used by the administrator for configuration purposes.
Based on construction plans, a 3D model of the building, the blinds and surrounded objects will be created. This 3D model is the basis for the simulation of the shadow of the building and its environment. The simulation is performed for every minute of the whole year.
Based on the simulation and different run time parameters, all blinds are controlled automatically. The control logic can be adapted to the needs of the building owner. In addition to the current weather situation, other parameters like a manual override or special operating and safety modes can be considered.
Considering the weather situation
One or more weather stations determine the current weather situation. You are free to choose any weather station. You might also use sophisticated stations, which measure the current global solar radiation.
The blinds can be controlled individually or per group.
In addition of the position of the blinds, also the position of the slats can be controlled automatically. The slat adjustment is controlled according to the elevation and azimuth angle of the sun.
In addition to the automatic control, you can also control the blinds manually. We can adapt the manual override to your project-specific needs.
Dynamic calculation of the brightness threshold
To include the current weather situation, you can define a brightness threshold and a hysteresis for each shading group. Dynamic adjustment of the threshold according to the elevation angle of the sun can avoid a glaring due to a low position of the sun.
