ELECTROCHROMIC GLASS

Up to 1% light transmission

Insulating glass for curtain walls that allows control of the amount of light passing through it in the range of 60% light transmission and up to 1% light transmission.

The glass eliminates all shading means (double skin, curtains, drapes, etc.), eliminates the glare and glare and allows a healthy natural light to pass through us and connects the interior and exterior.

The glass with SHGC varies in the range of 0.47-0.09 and therefore saves about 30% of the ongoing costs of air conditioning and also has the equipment of air conditioning systems. In addition, glass saves about 50% of glass lighting expenses. Using glass gives up to 36 LEED points.

Sensors can be connected to the glass so that the amount of light can be optimally adjusted for those staying in the space automatically and continuously. The glass has minimal energy consumption because a very low voltage of 5 volts is required to transfer the glass from one dark state to another.

FAQ

Can the solution come in film or laminated glass form?


A solution of electrochromic darkening glass comes only in the form of insulation. You can choose double glazing or triple glazing.




What is SAGE Electrochromic Dark Glass?


SAGE Electrochromic Glass is the leading electrochromic glass for exterior windows and curtain walls. The glass provides a variable light transmission and thereby prevents glare, glare and solar radiation. The glass is powered by an electric field at a very low voltage of 5 volts and negligible power consumption. The use of SAGE glass completely eliminates the need for shading solutions such as blinds or curtains and it significantly helps in reducing energy costs for air conditioning and lighting.




Where is the glass made?


The electrochromic darkening glass is made in the USA




What are the benefits of SAGE glass?


SAGE electrochromic darkening glass allows natural light to pass through all hours of the day, allowing connection to the landscape. Natural light has been shown to be healthy for humans and a more relaxed work environment. Glass saves energy by passing the warming rays of the sun in the winter season and insulating them on hot summer days.




Is SAGE glass suitable for any structure?


SAGE electrochromic tinted glass has been installed in a wide range of buildings and towers and is suitable for any project where controlling sunlight and heat is a challenge.

The use of glass has been used successfully in projects in commercial offices, schools and universities, hospitals and clinics, cultural institutions, government offices and skylights in a wide range of buildings around the world.




Why choose SAGE electrochromic darkening glass over standard heat-insulated glass?


SAGE electrochromic tinted glass is energy efficient and eliminates the need for shading solutions that block the landscape and natural light. Buildings constitute a very significant energy consumer and constitute almost 40% of the total energy consumption of the economy, as well as being responsible for emitting 38% of CO2 every year.

Energy loss through standard glass accounts for about 30 percent of heating and cooling energy, according to the U.S. Department of Energy. Curtains, shutters or other mechanized shading devices sever our connection with the outside. Prior to the use of SAGE glass, there was no way to combine natural daylight and outdoor landscape with control over the light, heat, brightness and glare of the sun’s rays.




Does SAGE electrochromic dark glass consume electricity?


SAGE electrochromic darkening glass operates on a very low electrical voltage of 5 volts DC. The glass consumes energy only at the glass transition from one light transition to another (there are 4 levels of light transitions).

To give a scale it can be said that a 60 watt bulb consumes more electricity than 186 square meters of SAGE electrochromic darkened glass.

As mentioned, energy consumption is negligible.




What are the maximum dimensions that can be ordered for the SAGE electrochromic darkening glass?


The maximum size is 1.75 meters wide by 3 meters long.




Where can SAGE electrochromic darkening glass be installed?


SAGE electrochromic stained glass is integrated in a wide range of residential buildings, commercial, institutional buildings, unique buildings and anywhere that sees the importance of using natural daylight. Because SAGE glass saves energy, it is optimal for sustainable buildings. The glass filters out 100% of the harmful UV rays and therefore protects internal spaces from fading.

SAGE electrochromic darkening glass is especially suitable for the following structures:

Commercial office space, schools and universities, hospitals and health facilities, museums, libraries, religious facilities, aviation facilities, atrium, skylight windows.




Is it possible to set SAGE electrochromic darkening glass so that the darkening and brightening operation is done automatically?


Yes, SAGE glass can be darkened and clarified automatically, manually or integrated into the building's smart home system. In general there is always the option to change the automatic settings by manually pressing the wall switch. The automatic system uses sensors inside and outside the glass and allows a real-time response of darkening or lightening depending on the intensity of the light inside and outside the space.




Does SAGE electrochromic darkening glass help protect the interior from sun damage?


Yes, when the glass darkens electrochromically it blocks 98% of the sun's radiation that causes fading and at the same time ensures comfort for those staying in space by passing and using natural light.




Why are traditional exterior glass and shading products unsustainable?


When you consider all the materials, production, transportation, installation, maintenance and operational energy they consume, the carbon footprint becomes quite significant. This is a very big disadvantage if striving for a sustainable building.

Electrochromic darkening glass SAGE is a green technology for saving energy and contributing to the increase in the value of the building.




Is SAGE electrochromic dark glass available in more than one color?


Yes, SAGE electrochromic tinted glass is available in a variety of colors to match the color of the glass to the design language of the building, a shade of gray, bluish or greenish.

Please contact us to discuss the best fit for your project.




Does SageGlass Glass Provide Privacy?


Electrochromic darkening glass SAGE is not a privacy glass. When the glass is completely dark on a sunny day, it is almost impossible to see through it to anyone outside the building, but because the glass is designed to preserve the exterior view, it does not provide 100% privacy.




In what forms can the SAGE electrochromic darkening glass be ordered?


We offer the following shapes as standard: rectangle, square, parallelogram, trapezoid and triangle. At the same time, we continue to expand our product line, so you should contact us and check availability of the requested form.




Does SAGE electrochromic darkening glass give the building LEED points?


Yes, glass can help your project get up to thirty-seven LEED credit points in five categories.




Does SAGE electrochromic darkening glass give the building LEED points?


Yes, glass can help your project get up to thirty-seven LEED credit points in five categories.




Where has SAGE electrochromic dark glass already been installed?


As of 2020, over 700 installations of SAGE electrochromic stained glass have been completed since the first commercial project was installed at a California hospital in 2003.

Since that installation the glass has been installed in hospitals, office buildings, schools and residences.




Is SAGE electrochromic darkening glass considered Low-e glass?


Yes, SAGE electrochromic dark glass has a Low-e layer so it provides all the benefits of a Low-e product when the glass is in light matzah and also in dark mode. Low-e coating helps keep the heat out when cold outside, and leave it outside on a hot day.




Is there a warranty on SAGE electrochromic dark glass?


SAGE, a company owned by the Saint Gobain glass conglomerate, has a warranty of up to 10 years for SAGE glass products, depending on the type of structure and installation, the electronics, the electrochromic functionality and the coatings have a five-year warranty.

Contact us for full details on product warranty.




What happens if SAGE electrochromic dark glass breaks?


SAGE glass is easy to replace. If the glass breaks, it can be replaced just like regular glass, it just needs to be disconnected from the electricity before it is discharged. Typically, a new IGU can be installed and reconnected to the low voltage wiring using a simple connector.




How does SAGE electrochromic technology work?


Coat the glass panels with five layers of ceramic material with a total thickness of less than 0.02 of the thickness of human hair. When voltage is applied across the coatings, ions move from one layer to another, causing a change in condition that causes the coating to tint and absorb light and heat.

In reversing the polarity the applied voltage causes the ions to migrate back to their original layer, and to the lightening of the glass.




How to make SAGE electrochromic darkening glass?


Use a Vacuum Deposition process also called Sputtering for conventional glass coating in layers consisting of oxides of metal. This is the same process used to make Low-e glass and glass with a double layer of Low-e coating.

SAGE glass is glued to plain clear glass then to one or two more pieces of glass (clear or dark) and one or two spaces to form double or triple insulated glass. The production facility is located in Paribo, Minnesota.

Tours are available for prospects.




Does SAGE electrochromic darkening glass have intermediate degrees of darkness?


Yes, with the SAGE control system, you can choose preset hue levels between 60% light transmission and 1% light transmission. The control system can also be programmed to maintain a constant light level within the space throughout the day.

In this case, sensors integrated in the frame will transmit information to the glass on how to adapt to the changing light conditions outside.




What control system options are available for SAGE electrochromic tinted glass?


SAGE electrochromic stained glass comes with a standard panel-mounted control system that can be operated via a simple wall switch, our automation system, or the building’s automation system that controls lighting, energy use, audio-visual equipment and security.

When SAGE glass is integrated into the building automation system, windows and screen wall components can be controlled by timers, lighting sensors, motion sensors, lighting control, thermostats and more. The innovative control system enables intelligent control of multiple areas.




Is it possible to control SAGE electrochromic darkening glass wirelessly?


Yes, when you combine SAGE glass with a building control system with wireless control and monitoring capability.




How fast does the degree of darkness of SAGE electrochromic darkening glass change?


SAGE electrochromic stained glass passes over 90% of its dynamic range (brightens to a dark or inverted hue) within 7-12 minutes. The speed of replacement depends on a number of factors, such as the ambient temperature and the size of the glass. The hotter it is outside, the faster the glass passages.

Large glasses take longer than small glasses. Also, transition from a given state to a shorter intermediate state.




What is the cost of SAGE electrochromic darkened glass compared to low-e insulated glass?


When comparing the total costs of curtain wall glass to the building envelope, SAGE electrochromic stained glass costs are usually equivalent to or lower than the existing alternatives on the market, as in most installations we eliminate the need for shading systems, associated costs, maintenance and future air conditioning energy savings.

While we may pay more when comparing SAGE electrochromic darkening glass with Low-e glass based on glass, this is not the correct comparison.




What happens when there is a power outage in a building?


When the power is turned off, SAGE electrochromic dark glass returns to maximum transparency within one to two hours.




What is the dynamic range of SAGE electrochromic darkening glass?


The percentage of visible light transmission in its transparent state can be changed from 60% to 1% in its dark state, with a solar heat gain coefficient (SHGC) varying from 0.41 at the high end to 0.09 at the low end.




Where is the smart coating of SAGE glass?


In most applications it is on the inner surface of the Electrochromic lite. At this location the coating blocks the heat of the sun before it enters the building, meaning there is less heat for the HVAC system to cool down. In contrast, curtains and shutters do not block the entry of heat into buildings, where you may not feel heat directly if curtains are drawn, but the heat still enters and must be air conditioned by air conditioning.




Has SAGE technology been independently tested? How durable is it?


SAGE technology has undergone rigorous performance testing and durability by independent third parties, including the US Department of Energy (DOE) and leaders in the glass manufacturing industry.

SAGE electrochromic tinted glass was one of the first products to pass ASTM E-2141-06 (standard test methods for assessing the durability of adsorbent electrochromic coatings on opaque insulating glass units).

In fact, SAGE technology has survived over 100,000 cycles of accelerated environmental durability testing. This is twice the test standard and is equivalent to replacing a window nine times a day for 365 days / year over 30 years of life, according to the DOE's National Renewable Energy Laboratory.
