2.1 the heat gain by conduction through an east-facing wall at 12 huU (Vvall I ype $y$, Area of the wall $=9.3{\mathrm{m}}^2$ ). (5) 2.2 the heat gain from solar radiation through a window at 14 h00 (Space Type A, Area of the window $=2.8{\mathrm{m}}^2,\mathrm{U}$-factor of the window $=3.75\mathrm{W}/{\mathrm{m}}^2.{}^{?}\mathrm{K}$, Shading coefficient of the window $=0.70$ ). (4) 2.3 both the sensible and latent heat gains due to infiltration of air from outdoors (Amount of infiltration $=0.5$ air changes $/\mathrm{hr}$, Volume of space $=85{\mathrm{m}}^3$. Indoor humidity ratio $=9.3\mathrm{g}$ ${\mathrm{H}}_2\mathrm{O}/\mathrm{kg}$ dry air, Outdoor humidity ratio $=13.1\mathrm{g}{\mathrm{H}}_2\mathrm{O}/\mathrm{kg}$ dry air). (5) [14]
