Commercial buildings – the Façade challenge

Glass is an unrivalled building material. Being it part of the façade construction, as roofing or as “ordinary windows”, glass is the centre piece of architectural design and makes the difference between a building or a landmark. A façade, or just a storefront. It provides a view to the outside world, it enables daylight to enter the building and stay in touch with your surroundings.

On the other side, glass is introducing its challenges to the building eco-structure and its users. Daylight is abundantly available – sometimes too abundant for users. Glare and direct sunlight exposure decrease the comfort of the users of the building.
Daylight is also bringing in energy to the structure, for which HVAC installations require large amounts of energy to control the inside climate. Unwanted air flows and high energy bills are the result. 

There are ways around this. Sun blinds, be it internal or external, can solve most of the problems. However, these systems are expensive, easy to tamper with and require a lot of maintenance: both technical maintenance and cleaning of the blinds. Besides these issues, sun blinds block the view to the outside world, resulting in “office lag”. Another possibility is to decrease the glass-to-wall ratio, with all design consequences on the façade and creative freedom. 

Office lag

Albeit not an official term, anybody can imagine what office lag is. Like a jet lag, you lose the connection between your biological rhythm and the actual day time. People get to work in the early morning, whilst it is still dark, or the sun has just risen. At the end of the day, people leave their office. On cloudy winter days, there is not a lot of light to enter the building. On sunny winter days however, due to the angle of the sun, it is shining into the building which is disturbing activities. Sun blinds go down or curtains are closed. Artificial light is switched on, to not sit in the dark.

What if we can provide you with a technology which allows you to control the amount of ambient light entering the building? Set the light transmission value to any value which is convenient for you, without losing touch to the outside world. 

How do we achieve this? We change only the light transmission, not the opacity – the haze level remains at a constant low level. We do it in multiple stages, so that there is always a transparency level which matches your needs. We do it fast: in a matter of seconds. This transition time allows your eyes to adjust to new light conditions, without discomforting flash effects.

implications when using eLstar Dynamics smart glass

The ability of our technology to remain transparent and adjusting the light transmission value to reach all comfort levels is almost unmet. Additionally, we can color tune the glass’ color to any color which the architect or end customer aspires. Being it your brand colors or to be less (or more) conspicuous to your surroundings: we can do all. 

By implementing our technology in your design, you can increase the amount of usable square meters in the structure. On top of this, there is no further need for sun blind systems. Besides the increased comfort and decreased costs, eLstar Dynamics smart glass helps you to reduce energy costs: less cooling and heating, as well as a lower need for artificial light inside during the day.

Terminals and malls are large structures with large area’s of glass. Hence, a big build up (or loss) of heat. HVAC is layed out for peak loads. Reducing the peaks reduces the investment, environmental footprint and usage costs of such buildings.
