3. Introduction: Smart Glass
SMART GLASS or switchable glass (also smart windows
or switchable windows) is glass or glazing whose light
transmission properties are altered when voltage, light
or heat is applied. Generally, the glass changes from
translucent to transparent, changing from blocking
some wavelengths of light to letting light pass through.
Window glass that can tint on demand is pretty slick.

4. Types of Smart Glass :

5. Lets take each type one by one.
Liquid Crystal:
• Allows light flow with privacy.
• Used for privacy control.
• Changes on demand with an
electric current.
Advantages: Privacy at the flip
of a switch, no window coverings needed.
Disadvantages: Does not conserve energy.

6. Low‐E
•Traditionally used energy efficient glass.
•Glass treated with invisible metallic
coating to reflect or trap light & heat.
•Reduces the amount of ultraviolet light
that enters your home without blocking
visible light.
•Advantages: Limits UV rays, reduces energy bill, prevents
furniture from fading, reduces sound levels in home.
•Disadvantages: More costly than regular glass, slight
haze to windows, no manual control, no control over
visible light.

7. Thermochromic
•Tint level based on temperature of the
material.
•Adapts directly to changing sunlight intensity.
•Combined with low‐e technology.
•Advantages: Continuously adapts tint to sunlight to
manage heat & glare, installation is as same as
traditional windows, No power supply needed.
•Disadvantages: Cannot be manually controlled
glass may not receive enough heat from direct
sunlight to darken, added weight to insulated
glass units.

8. Electrochromic
• Electrical current creates chemical reaction
causing window to tint.
• Depending on electrical current,
selectable darkness allows more control
over sun levels.
• Current is not required to maintain tint
levels, only to change colour states.
• Very little current needed (power
entire building of electro chromic
windows equal to one light bulb).

9. Benefits
● It’s easy cleaning.
● It’s saves money & keeps the house cool.
● It blocks UV-Rays & protects furniture.
● It doubles as a protection screen.

10. Technology in Smart Window
It has four technologies which are as follow :
1. Photochromic or photo chromatics.
2. Liquid Crystals.
3. Suspended Particle Displays.
4. Electrochromics.

11. Future of Smart Glass :
• Increase cost efficiencies.
• Integration of smart glass with other electrical
systems within such as the HVAC & lighting
systems.
• Photovoltaic smart glass generating electricity
while darkening windows with thin film of PV
panel.
• Wireless systems.
• Other electronics in glass such as thermometers
or display.

12. Why use Smart Glass?...
● Control the amount of privacy, light & heat that
enters a space manually or automatically.
● Switch instantly or dim anywhere in between.
● No need for curtains.
