Introducing a Unique Balance in Window Blind AutomationDouble-Skin Glass Façade buildings are becoming a fixed feature of the contemporary urban skyline. This trend, which involves an architectural shift to glass-based exteriors, considerably hastens the completion of building projects as well as providing energy-efficient solutions required for modern structures [1].

This efficiency is due to full exploitation of the natural sunlight and the isolation provided by the air sandwiched between the two glass layers which helps keep out the heat or cold. During winter time, not only is insulation provided, but the sandwiched air, warmed up by the sun, is thrown back into the facility’s ventilation system [2].

This double-skin layout is typically designed for hosting motorised window-blind systems, providing superior climate control, by letting in sunlight, while blocking direct radiation. However, proper use of these blinds is at the mercy of users inside the offices or living spaces. When unattended, these blinds might, one morning, inadvertently remain in the up position, enabling the ingress of unwanted direct solar radiation or might be left down in the evening, preventing needed sunlight the next morning.

Wouldn’t it be nice if we could have ultimate control over the aperture of our blinds, optimising at any given moment the delicate balance between access of the desired indirect sunlight and blocking unwanted direct radiation; and as an automated solution, to boot?

We − at Control Applications − are proud to inform you that such a solution exists.

Take note

• Double-skin glass facades entail shade systems which require control.
• The SLT controller, developed by Control Applications, uses a unique control algorithm, providing optimal aperture for window-blinds and infrastructure for LED lighting control.
• This optimal aperture provides energy efficiency and aesthetics.
