Heat Load Calculation Program Development:

Utilizing the $99\mathrm{.}6\%$ design conditions, calculate the hourly heat loss of the small one$-$story slab$-$on$-$grade office building section shown in the schematic below. Develop a software

program or spreadsheet for your calculations. The building is located in Bozeman, Montana. The indoor conditions will be maintained at $68FBB,30\%RH.$ The following data

applies $($use the latest ASHRAE Standard $62$ provided for this course$)$:

a$.$ Plan dimensions: $50ft50ft$

b$.$ Orientation: As Shown

c$.$ Height: $,15ft$ to the underside of the roof construction

d$.$ Walls:

$U=0\mathrm{.}091BT\frac{U}{h}r*f{t}^2*F$

e$.$ Roof:

$U=0\mathrm{.}042BT\frac{U}{h}r*f{t}^2*F$

f$.$ Doors: Solid wood swing door with metal storm door

Doors are $3ft7ft,$ with $(1)$ on the east side and $(1)$ on the north side $($hallway

entrances$)$

g$.$ Windows: Double insulating glass, $1$ in$.$ air space

Office $1$: $100f{t}^2$ on north wall

Office $2$: $100f{t}^2$ on north wall, $100f{t}^2$ on east wall

Conference $1$: $100f{t}^2$ east wall, $200f{t}^2$ on south wall

Hallways: No windows

h$.$ In filtration: Building is well insulated and sealed, windows are not operable

i$.$ Ventilation:

j$.$ Slab Edge:

As required for proper health per ASHRAE standard $62\mathrm{.}1-2013$

$2$ in$.$ of insulation
