What is the ideal window size for a north-west-facing kitchen in Ahmedabad?

Vastu and composite climate together suggest a window approximately 4 feet wide with a sill height of 2.5 feet on a north-west face for a kitchen in Ahmedabad. Type: Sliding 2T. Glazing: clear.

Is North-West an auspicious direction for a kitchen per Vastu?

North-West is an acceptable secondary placement for a kitchen. The traditional ideal is SE, but the room remains usable in North-West 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 kitchen?

Kitchen windows must extract cooking smoke and steam (so an exhaust-fan window over the cooktop is non-negotiable), let in morning light when the kitchen sees dawn use, and ideally allow a glance at the entry / dining area for family interaction while cooking.

Vastu's ideal placement for a kitchen is SE. North-West is an acceptable secondary band.

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 north-west 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

Sink directly below the window — splashing wets the wall and corrodes the sill
No exhaust window over the cooktop — steam damages the ceiling
South-facing kitchen window with no shading — afternoon heat compounds the cooking heat
