RFI Q3 204 CC, post 6:
And some of the key insights from this study include, and this is pretty remarkable, so they compared SPD
to high energy efficient low e double glazing. And the study concluded that compared to these low e IGUs, SPD SmartGlass reduced net energy consumption by up to 58%, thanks to the dynamic control of heat and light.
And also this feature eliminates the need for additional shading devices, cutting both energy and maintenance costs. The other thing was daylighting optimization. The SPD study, the glass that we used had a dynamic range of 0.1% to 60% light transmission for reducing glare and enhancing visual comfort.
And this study demonstrates that SPD's effectiveness across various building elements like skylights, courtyards and clerestory windows was dramatic. You know, years ago over 6,000,000 visitors saw these and other benefits of SPD firsthand at the World's Fair USA Pavilion.
Their SPD glass was integrated into a 10,000 square foot roof controlled in real time allowing for automatic adjustments as well as manual adjustments. For instance, in the peak sun, the glass darkened to reduce heat and protect occupants, but during evening events, it created a dynamic flashing disco event in the roof.
What the study also noted in Saudi Arabia was that SPD SmartGlass is especially advantageous for hard to shade areas like skylights and atrium, offering a simpler, more reliable solution than mechanical shading systems. This flexibility helps architects tailor lighting to specific zones such as maintaining optimal lighting in classrooms or enhancing user comfort in any environment.
And if you notice that the study had zeroed in on the optimum tint to be used on different areas of the building. And this is quite helpful data for architects and highlights the benefits further of SPD SmartGlass technology.
So let's say, for example, you're trying to maintain a 30% transmission rate in your skylights or glass atrium, which they said was the good target. With changing outdoor lighting conditions such as any movement of the sun or time of day, the ability to dynamically adjust the tint of glass to result in this 30% light transmission is quite easy and automatic with SPD.
And the study also noted that SPD SmartGlass helps achieve balanced daylighting distribution in clerestory windows. So basically the idea here is that there can be on demand control. For example, when I was at CERN where the Super Particle Collider is in Switzerland, they use our SPD SmartGlass in the large dome at the visitor center.
And when the head of CERN met me and gave me a tour of the facility, he noticed that they constantly use the SPD SmartGlass in different ways. For example, if they're having an event under the dome, they may let more light in. If they're doing a multimedia presentation inside the dome, they will darken the glass at the top of the dome using the SPD.
So there's the on demand application of SPD and there's also the set it and forget it ability where in real time the glass can change instantly and automatically based on your user preferences to maintain constant control over heat, light and glare.
Now one of the questions we got from John Nelson is, will AI be used to control our glass? And it's very, very simple to do that. And here's a good example where you could either use simple methods like photo cells or timers or building control systems or you could use AI to automatically tell the glass what to do.
And because we have instant response time, John, you get much better results than having to wait 40 minutes for your windows to switch as you would with a electrochromic window. So just getting back to the Saudi Arabian study, it concludes that SPD SmartGlass proves to be an efficient, adaptable daylighting solution with transformative potential across various types of spaces, especially in climates where controlling heat and light is crucial.
The study also adds to the body of knowledge started by the prestigious Cambridge University study about the benefits of SPD technology among architects and building designers and engineers.
