Building information:

Slab$-$on$-$grade foundation with $4"$ lightweight aggregate concrete slab, $2"$ polystyrene foam under the slab and $2"$ polystyrene foam on the edge that goes $1ft$ deep. The footprint of the building is $80ft$ by $60ft.$ The building has $3$ stories. The floor$-$to$-$ceiling height is $9ft.$ The walls are metal$-$frame with o$.$c$.$ The stud cavity is filled with ${3\mathrm{.}5}^{\text{'}\text{'}}$ batt insulation made of mineral fiber. On the outside of the

stud wall there is $\frac{3}{4}$ "plywood, $1^{\text{'}\text{'}}$ of expanded polystyrene board insulation, $1^{\text{'}\text{'}}$ air gap and then $4$ "brick veneer. On the inside of the stud wall there is $\frac{1}{2}"$ gypsum board. Each story of the building is a separate zone. Ignore any heat exchange between second floor

and the other two floors through the floor and ceiling.

The first floor has $3$ windows of type $1$ and $2$ windows of type $2.$ The location of the windows is not important. The first floor has two $1-3/4"$ steel doors with polyurethane core without thermal

break. The doors are $4ft$ wide by $7ft$ high.

The second floor has $6$ windows of type $1$ and $2$ windows of type $2.$

The third floor has $2$ windows of type $1$ and $6$ windows of type $2.$ The roof is made of the following layers from inside to outside: ${0\mathrm{.}75}^{\text{'}\text{'}}$ acoustical tile, $5^{\text{'}\text{'}}$ air space $($extrapolate$)($mean temperature $=50F,$ delta $T=10F,=0\mathrm{.}5),{3\mathrm{.}5}^{\text{'}\text{'}}$ lightweight aggregate concrete, $2^{\text{'}\text{'}}$ mineral fiber with resin binder insulation, $3^{\text{'}\text{'}}$ of loose$-$filled expanded perlite with a density of $6lb\frac{m}{f}{t}^3.$

Type $1$ window:

Overall dimensions: $5\text{'}$ by ${3\mathrm{.}5}^{\text{'}},$ double$-$glazing with $\frac{1}{4^n}$ argon space. The windows are operable with uninsulated vinyl frame. The frame is $2^{\text{'}\text{'}}$ wide, the edge width is $\frac{1}{2}".$

Type $2$ window:

Overall dimensions: $7\text{'}$ by $4\text{'},$ same as type $1$ except that the windows are inoperable $($fixed$)$ vinyl.

Weather information:

The building is located in Pittsburgh, PA and the indoor temperature is to be considered $75F.$

Note: For any missing information you may make reasonable assumptions.

Deliverables:

$1-$ An Excel file with sufficient notes on the cells or next to the cells. A separate sheet must be created for each floor, and a $4^{th}$ sheet that summarizes the results.

$2-$ A Word file showing the work. Make reference to the tables from which you obtained the needed values. Add a title page. Include a dimetric view of the building $($SolidWorks$).$
