East Wall — Openings (per latest markups)

Origin at bottom-left of wall (x right, y up). Units: inches unless noted.

Wall outline: width \(W=\mathbf{632}\) in (52.67 ft), height \(H=\mathbf{306}\) in (25.50 ft).
Openings:

Small Door: start \(x=\mathbf{24}\), width \(=\mathbf{40}\), height \(=\mathbf{88}\).
Louver: BL \(=\mathbf{(154,156)}\), TR \(=\mathbf{(264,240)}\) → \(110\times84\).
Door #2: start \(x=\mathbf{276}\), width \(=\mathbf{76}\), height \(=\mathbf{84}\).
Door #3: \(36\) in to right of Door #2 → start \(x=\mathbf{388}\), width \(=\mathbf{76}\), height \(=\mathbf{84}\).

Drawing is literal scale: 1 px ≈ 1 in. Louver shown in green outline for easy spotting.

Opening	Bottom-Left (x,y)	Bottom-Right (x,y)	Top-Left (x,y)	Top-Right (x,y)	Size
Small Door	(24, 0)	(64, 0)	(24, 88)	(64, 88)	40 × 88
Louver	(154, 156)	(264, 156)	(154, 240)	(264, 240)	110 × 84
Door #2	(276, 0)	(352, 0)	(276, 84)	(352, 84)	76 × 84
Door #3	(388, 0)	(464, 0)	(388, 84)	(464, 84)	76 × 84

Item	Calculation	Value
Wall gross area \(A_g\)	\(632 \times 306 \div 144\)	1343.0 sf
Small Door area	\(40 \times 88 \div 144\)	24.44 sf
Louver area	\(110 \times 84 \div 144\)	64.17 sf
Door #2 area	\(76 \times 84 \div 144\)	44.33 sf
Door #3 area	\(76 \times 84 \div 144\)	44.33 sf
Total openings \(A_o\)	Sum	177.27 sf
Opening ratio \(A_o/A_g\)	\(177.27 / 1343.0\)	0.132 (13.2%)

Sanity check on “91 in spacing”: Small Door ends at \(x=24+40=64\). Your louver BL at \(x=154\) makes the clear gap \(154-64=\mathbf{90}\) in (close to the 91″ you mentioned). I used your explicit louver coordinates.
