Question $2$:

A$)$ In a building in Ankara, in the wall section given below, How many centimeters should the thickness of the thermal insulation layer be at least?

$2cm$

$20cm$

$?$

$2cm$

interior plaster $($cement mortar $2000k\frac{g}{m^3})(650\frac{kg}{m^3})$:$1\mathrm{.}6\frac{W}{m}K$ aerated concrete thermal insulation $-$ XPS foamboard $..(25\frac{kg}{m^3})$:$0\mathrm{.}25\frac{W}{m}K$ exterior plaster $($cement mortar $2000k\frac{g}{m^3})$:$0\mathrm{.}040\frac{W}{m}K$:$1\mathrm{.}6\frac{W}{m}K$

For Ankara $U=0,48\frac{W}{m^2}K$ 'dir.

$Ri=0,13m^2\frac{K}{W}$

$Re=0,04m^2\frac{K}{W}$

$ti=22C$

$te=-24C$

B$)$ After finding the thickness of the thermal insulation layer, for the wall section given in the above question, what is the amount of heat flow per $1m^2$ of the wall $($heat loss per unit time$)?($Find the q value.$)$

C$)$ Find the difference between the wall surface temperature and the ambient air temperature and examine the thermal comfort condition of the wall section given.

According to the thermal comfort conditions, how does the user $($occupant$)$ feel inside?

$($Very comfortable, Comfortable, Less comfortable, Uncomfortable, Cold, Very Cold$)$
