a A long rectangular house has a simple isosceles triangular roof, with a roof pitch = 20 deg, measured from the horizontal plane. The sun irradiates one external side of the stainless steel roof with Gsolar = 800 W/m^2, warming the roof to 80 deg C. Then the interior surface of the roof radiates energy into the attic. Assume that all the surfaces inside the attic are blackbody. What is the expected temperature of the ceiling surface (base of isosceles triangle, width = 6 m)?
