Every window is unique

Due to a variety of influence factors light intake differs from one window to another

Limitations of currently used physical sensors

A difficult compromise between various factors

One sensor = one spot on the surface.
A minimal viable monitoring system requires at least one sensor per window.

Precision OR
Budget & Aesthetics

Physical sensors are costly to purchase, to install and to maintain.
Too many physical sensors on your building’s facade is a sacrifice made on its final looks.

Even budget expenditure cannot overcome hardware shortcomings
Real conditions
Physical sensor Data
applied conditions

Physical sensors only approximate the shading conditions.
The actual conditions on the window surface differ a lot.

Match the real shading conditions with virtual sensors

Leaftech sets up the adequate amount of sensors on each of your windows

Real conditions
Virtual sensor data
applied conditions

LeafTech sets up a digital twin of the building and assembles all influence factors. As soon as the data sets are merged, a grid of virtual sensors is generated and linked to the current weather conditions.

Advanced information quality

Virtual sensors can be used for real time measurement of different parameters.
