Determine the design heating load for a residence, $30$ by $100$ by $10ft($height$),$ to be located in

Windsor Locks, Connecticut $($design indoor temperature is $72F$ and $30\%RH$ and outdoor

temperature is $3F$ and $100\%RH,$ which has an uninsulated slab on grade concrete floor $(F=0\mathrm{.}84$

$Bt\frac{u}{h}Fft,$ which can be converted to volumetric flowrate in CFM

for calculating sensible and latent loads. The construction consists of

Walls: $4$ in$.$ face brick $(R=0\mathrm{.}17)\frac{,{?}^3}{4}$ in$.$ plywood sheathing $(R=0\mathrm{.}93),4$ in$.$ cellular glass

insulation $(R=12\mathrm{.}12),$ and $\frac{1}{2}$ in$.$ plasterboard $(R=0\mathrm{.}45)$

Ceiling$/$roof: $3$ in$.$ lightweight concrete deck $(R=0\mathrm{.}42),$ built$-$up roofing $(R=0\mathrm{.}33),2$ in$.$ of

rigid, expanded rubber insulation $(R=9\mathrm{.}10),$ and a drop ceiling of $\frac{1}{2}in.$ acoustical tiles

$(R=1\mathrm{.}25),$ air gap between rubber insulation and acoustical tiles $(R=1\mathrm{.}22)$

Windows: $45\%$ of each wall is double pane, nonoperable, metal$-$framed glass with $\frac{1}{4}in.$

air gap $(U=0\mathrm{.}69)$

Doors: Two $3ft$ by $7ft,1\mathrm{.}75in.$ thick, solid wood doors are located in each wall

$(U=0\mathrm{.}46)$

All $R$ values are in $hrf{t}^2\frac{F}{B}$ tu and $U$ values are in $Bt\frac{u}{h}rf{t}^{2}F$ units. $R=\frac{1}{U}.$
