Summary

Airport terminals typically have a lot of glass façades that pose the challenge to provide a comfortable and natural lit interior while realizing effective glare control. Large numbers of passengers spending increasing amounts of time in airports generate the need for greater comfort and a better experience. VideowindoW is the answer to these growing needs of the airport industry. VideowindoW is glare control with an added communicative and profitable values; a sustainable and comfort enhancing alternative for traditional glare control. VideowindoW’s unique features are best enjoyed in large public spaces especially where glass is an essential element of the architecture. The opportunity to show commercial content unlocks the value of hitherto unprofitable glass façades.

Facts

VideowindoW

Enhances the experience for and well being of the audience in the public domain

Introduction

VideowindoW is glare control with an added communicative value. Glass allows for natural light to enter buildings and protects against weather conditions. The transparency and comfort it offers, is usually diminished by conventional glare control. VideowindoW is the first dynamic transparent glare control that enhances comfort and well-being in public spaces. Based on light sensors VideowindoW controls the transparency of tiny segments of glass, as fast as 60 times per second, thus enabling access of natural light and glare control in a gradual and optimal way. The technology can actively be utilized to create images within the glass. VideowindoW’s glare control hence becomes content and vice versa.

Benefits from VideowindoW

VideowindoW embraces natural light instead of blocking it, and as a result, VideowindoW can lower energy use for interior lighting and climate control up to 30%. The communicative function offers architects and designers new narrative applications for glass façades, comparable to stained glass in the past. By showing commercial content, VideowindoW transforms glass from a cost to a profit driver.

Product

VideowindoW is a modular product, and for every situation, a ‘fit-for-purpose’ solution can be designed. VideowindoW is pre-assembled which enables for quick installation on the final location (either newly built or as a retrofit solution to existing glass panels). Each module is equipped with a light sensor, and it uses advanced algorithms to incorporate real-time data from exterior luminescence and temperature. This is key to VideowindoW’s ability to show moving content while realizing glare control. The viewers will experience interior luminescence as stable, comforting and entertaining.

Highest grade specifications

VideowindoW’s thermal insulation qualities compare favorably to those of regular insulation glass / HR+ glass. Through continuous improvement we keep optimizing VideowindoW’s performance.

As sunlight travels through glass its thermal energy is reflected, absorbed or transmitted. Greater transmission results from more transparency which in turn leads to higher temperatures inside a building, unless active climate control exists. Reduction of transmission is feasible by applying foils or e-coating, but will inevitably result in higher absorption. This may cause the temperature of the glass itself to rise and through convection and radiation lead to an increase in interior temperatures. Exterior mechanical blinds or shutters will reflect most of the thermal energy and keep interior temperatures at bay but hinders or even blocks the exterior view and moreover the glass façade remains unprofitable.

VideowindoW consists of modular components between double glass. As these components dynamically lower their transparency to create glare control, their temperature will increase as more thermal energy is absorbed. By bonding our components to the exterior glass layer, this thermal energy is however largely dissipated into the exterior airflow. On the inner glass layer, e-coating may be applied. Being fully integrated within double (or even triple) glass, VideowindoW ensures thermal insulation in addition to glare control. In colder climates or seasons, VideowindoW can reduce its thermal absorption to let the sun warm up the interior, thus reducing costs for climate control.
