Intelligent Shading Control for Energy Efficiency and Comfort

NETx Shutter Control is an advanced shading solution for complex buildings that integrates with the NETx BMS Platform to optimize energy efficiency and comfort. It employs a 3D model of the building, factoring in sun position, seasonal variations, weather, and surrounding structures' shadows for precise control. This solution is designed for large structures, supporting centralized control and visualization of thousands of blinds. Using data from weather stations and sophisticated control logic, NETx Shutter Control enables both automatic and manual adjustments, customizable shading groups, and dynamic brightness thresholds, enhancing building automation efficiency.
Only included in connection with the NETx BMS Platform

3D Simulation of Shutter Control with Dynamic Sun Path and Shadow Projection

The simulation integrates building geometry and surroundings to visualize dynamic shading and sun angles across the day or year. This aids in optimizing shading control for improved energy efficiency and indoor comfort.

Functions

3D Modeling

A 3D model of the building and surrounding objects is created to precisely simulate shadow paths and optimize the shading control.

Automated Control

Based on simulations and real-time weather data, the blinds and slat positions are automatically controlled.

Weather Integration

Weather stations measure global solar radiation and other factors to adjust the shading accordingly.

Group Control

Blinds can be controlled individually or in groups, depending on the need.

Manual Control

In addition to automation, manual control is available, allowing customization to specific project requirements.

Dynamic Brightness Threshold

Adjustable brightness and hysteresis thresholds are available depending on the sun’s position, helping to prevent glare.

Slat Adjustment

The slat positions are automatically adjusted according to the sun's position to create optimal lighting conditions.

Centralized Management

Thousands of blinds can be centrally managed and visualized.

Smart Shading for Complex Projects

The  shutter control system optimizes shading by utilizing sun position, building geometry, and environmental factors


Advanced Geometric Modeling for Precision Shading

3D-Volume Model

A 3D-volume model provides a detailed representation of building geometry, enabling precise calculations for shading, sun paths, and shadow projections to optimize energy efficiency and indoor comfort.

Grid Model

A grid model divides the building surface into segments, enabling precise analysis of shading, sunlight distribution, and shadow patterns for optimized control of blinds and energy efficiency.

Window Grid Model

The window grid model divides window surfaces into smaller segments, allowing detailed analysis of sunlight exposure, shading, and shadow dynamics to optimize blind positioning.

 Shutter Control App

The Shutter Control App is accessible through the Web Manager of the NETx BMS Platform. It is used to configure and control the Shutter Control Module.
