Master bedroom. How many Btuh will you lose through the two outside bedroom walls? Use your "Area

A$"$ actual cavity R$-$value de$-$rated by the thermal bridging value provided in paragraph $2$A and the

dimensions provided on the floor plan to calculate your losses. Assume that your $T$ is based upon the

winter outside design condition and your inside set temperature. Estimate your $2$x$6$ average R$-$value per

inch based upon $5-1/2"$ of hem$-$fir softwood lumber found in Appendix E of your text.

How many Btuh will you lose from this house via ventilation and infiltration on a typical day during the

heating season? Assume that your infiltration rate is an additional $10\%$ of your minimum ventilation rate

of $0\mathrm{.}3$ACH of the building's nominal interior volume provided on the main floor and in the basement.

Use the floor areas provided on the floor plan and calculate an effective ceiling height for the main floor

by averaging the two heights provided in the plan for the main room and living room. Assume that the

effective basement height is $9$ feet from concrete floor to the under side of the first floor.
