At eLstar Dynamics, we are working every day to continue the development of our future product line.
Added Value: the best technology available
It’s eLstar Dynamics mission to bring switchable glass (or smart glass as it is often called) to the mainstream market and out of its niche. As such, we have taken an approach which focuses on the total cost of ownership. Why would you chose for an active façade over a passive, non-switching façade?
At eLstar Dynamics, we developed a technology which is suitable for large areas due to its low cost – both in terms of installation and running costs such as power consumption and maintenance.
eLstar Dynamics switchable glass in a nutshell:
Light transmission range: 0.2% – >50% within the same device
Switching time: Multiple seconds, independent of size
Color shift: None – black remains black
Temperature stability: Excellent (High & Low temperature)
Additional benefits: low power, low current system which eliminates the need for sun blinds, curtains or Low-E / IRR coating.
* We can color match almost any requested color for specific projects. Black however is the most popular color.
Total cost of ownership
We focus on total cost of ownership including investment costs, versatility of the technology and reliability. As a building owner, or the person/company paying the electricity bill, you want to know several things. First of all: how much will be the investment compared to a non-switching static façade? Secondly, it is crucial to know how much of the peak load for cooling is reduced as this determines the investments needed for the air-conditioning system and cooling channels. As a third, operating costs are important: power consumption versus power saved, but also maintenance costs.
What we can say about it at this moment is that the investment cost for our switching glass will be below the value of most sun blind systems. Any additional savings on HVAC investment is therefore a bonus. On running costs, the energy saved is much larger than the energy spent on operating. How much though depends on the exact design: concentration of particles, operating mode, electrode design, drive scheme, climate and latitude. Because of these parameters, it is impossible to say upfront how large the savings will be. In terms of maintenance costs: our switchable glazing requires no extra maintenance. Just clean them as you would clean ordinary windows.
All components and ingredients used in our smart glass are industrialized materials. The majority comes from the automotive sector in which they have been tested to their absolute limits and beyond. By using these materials, we are certain that our products are save and reliable under all circumstances, satisfying our customers needs for many years at end.
