Revolutionary Heat-Reflecting Glass: The Future of Energy-Efficient Buildings

The video discusses the high power consumption of air conditioning systems in glass office buildings and introduces a new technology developed by Professor Ivan Parkins' team at the University of London. This technology involves a special coating for glass that reflects the sun's heat while remaining transparent. The coated glass can deflect 30 to 50% of unwanted solar heat, potentially reducing air conditioning costs. The product is currently being tested for commercial feasibility and could be available in four to five years.

What is one of the main issues with air conditioning systems in glass office buildings?

• They are not effective in cooling.

• They are too noisy.

• They consume a lot of power.

• They are difficult to install.

What is unique about the glass coating developed by Professor Ivan Parkins' team?

• It remains transparent while reflecting heat.

• It is completely opaque.

• It changes color with temperature.

• It absorbs all sunlight.

How does the new glass coating affect the wavelengths of the sun's rays?

• It amplifies them.

• It reflects the heat wavelengths.

• It absorbs all wavelengths.

• It only reflects visible light.

What percentage of unwanted solar heat can the heat-reflecting glass deflect?

• 60 to 70%

• 80 to 90%

• 30 to 50%

• 10 to 20%

When is the heat-reflecting glass expected to be commercially available if tests are successful?

• In four to five years

• In two to three years

• In one to two years

• In six to seven years
