What is the ideal window size for a east-facing dining room in Ahmedabad?

Vastu and composite climate together suggest a window approximately 4.5 feet wide with a sill height of 2.5 feet on a east face for a dining room in Ahmedabad. Type: Sliding 2T. Glazing: clear.

Is East an auspicious direction for a dining room per Vastu?

East is an acceptable secondary placement for a dining room. The traditional ideal is W, but the room remains usable in East with the standard window choices.

Why does Ahmedabad's composite climate need clear glazing?

Ahmedabad sits in the Composite climate zone (Hot summers, cold winters, monsoon — the climate where classical Vastu was calibrated.). For composite climates, clear glazing balances solar gain, heat retention, and visibility — Operable windows matter more than fixed ones. The same opening that bleeds heat in January welcomes it back in July.

Why this direction for a dining room?

Dining-room windows want soft, even light during meal times (especially evening) and connection to the kitchen-side air for serving comfort. A west-facing window with light afternoon shade is the classic choice — it catches the soft golden hour during dinner.

Why Ahmedabad's climate matters

Ahmedabad is in the Composite climate zone (Cwa, Cfa per the Köppen scale; Composite per NBC 2016). Summer temperatures: 35-48°C, winters: 2-15°C. Rainfall: 500-1200 mm/year. Humidity: 20-90% (seasonal).

Operable windows matter more than fixed ones. The same opening that bleeds heat in January welcomes it back in July.

For a east face in this climate, the recommendation is a sliding 2t window with clear glazing and a sill at 2.5' — calibrated for hot summers, cold winters, and seasonal monsoon.

Common mistakes

Mirror directly opposite the dining table reflecting food / diners
Sliding doors instead of windows — diners feel exposed during meals
Diners face the glare of an unshaded west window during evening meals
