Use Parallel Path method and Isothermal method calculate the U (conductance) of the 38 by 90 mm stud wall shown in the figure. The studs are made of wood (California Redwood) with 400 mm OC. There is 90 mm mineral fiber batt insulation in the stud space. The inside finish is 13 mm gypsum wallboard, and the outside is finished with rigid foam insulating sheathing (R=0.7 m^2*K/W) and vinyl siding (R=0.11 m^2*K/W). Assuming exterior and interior convective coefficient is 30 and 8 W/k*m^2 respectively. Please explicitly list the calculation procedures.
