How Much Electricity Does Privetek Switchable Glass Really Consume?

Energy efficiency is no longer optional in modern Indian architecture. With rising electricity costs, sustainability mandates, and green building certifications gaining importance, architects and specifiers are increasingly cautious about power-intensive technologies.

Yet, many still assume that Switchable Glass consumes high electricity.

Privetek Switchable Glass breaks this myth with real, measurable numbers. Making it one of the most energy-efficient privacy solutions available in India.

Actual Power Consumption

Privetek Switchable Glass is designed to consume power only when transparency is required.

Power consumption (ON / transparent): 4 watts per square meter
Power consumption (OFF / opaque): 0 watts

This means there is no continuous electricity draw when the glass is in privacy mode.

Real-cost Example

For a standard office cabin with 9.5 sqm of glass:

Total power draw: 38 watts
Monthly usage (10 hours/day): 11.4 units
Monthly cost at ₹15/unit: ₹171

Even in high-usage commercial environments, the operational cost remains negligible.

How Does This Compare?

A ceiling fan typically consumes 70–90 watts.
Office lighting often exceeds 100 watts.
Air conditioners draw 1000+ watts.

In comparison, Privetek Switchable Glass is one of the lowest electricity-consuming components in a modern Indian office, despite offering instant privacy and premium aesthetics.

Why This Matters

NO hidden operating cost
NO impact on energy ratings
NO compromise on privacy or aesthetics

Long Lifespan = Higher Sustainability

Privetek Switchable Glass is engineered for long-term performance, with a lifespan of 10 years or more, reducing the need for frequent replacements and supporting sustainability across India’s commercial and residential building lifecycle.
