The walls of your house generally consists of bricks of thickness 10 cm with thermal conductivity 1 W/(mK). If your house temperature is 20 C, and the outside is at 4 C (with a wind causing the convective heat transfer coefficient to be 40 W/(mK)), what is your steady state heat loss (in W) for the house if the total wall areas you have in contact with outside is 100 m? If you also have an insulation layer of thickness 5 cm outside of the bricks with thermal conductivity of 0.06 W/(m-K), what would be the heat loss under the same outside air conditions? By what percent can you prevent the total heat loss
