Shown in the figure is a storage facility built in the shape of a parallelepiped. Details of the walls and the roof are also shown. The thickness of the paint, is 5 mm. The thickness of the sheet rock, insulation, and brick is 4 cm, 15 cm, and 5 cm, respectively. Estimate the heat loss in a Winter day where
T_f

= 0 C and the indoor temperature is maintained at 25 C. Use
h_i

= 4 W/m K and
h
_o
= 10 W/m K.
