Question

For calculations, take the typical frequency of visible light and aluminum conductivity

ω = 4 x 10¹⁵s^-1

σ = 3.8 x 10^7 Ohm/m

One-way mirrors are made of aluminum film so thin that it allows some light to penetrate
it. Find the thickness of a film on one-way mirror that allows 5% of incident light to penetrate
it. (Some portion is reflected and some portion is absorbed in a conductor.)

My question is if there is a building with 1000 windows and the building windows have a dimension of 2 metres width, 4 metres height and a thickness of 1.5 centimetres. It has a thermal conductivity of 0.96. And the temperature outside of the building is 35 degrees and the temperature inside of the building is 24 degrees. What is power output that AC's in the building must do to maintain the 24 degree temperature?
