What is the ideal window size for a north-east-facing bedroom in Ahmedabad?

Vastu and composite climate together suggest a window approximately 5 feet wide with a sill height of 2.5 feet on a north-east face for a bedroom in Ahmedabad. Type: Sliding 2T. Glazing: clear.

Is North-East an auspicious direction for a bedroom per Vastu?

Vastu's traditional ideal for a bedroom is W, NW, not North-East. The room remains habitable with simple window-design choices that neutralise the directional bias — see the recommendations on this page.

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.

North-East-facing Bedroom

North-East is not the traditional Vastu placement for a bedroom, but the room remains usable. Window design + simple remedies neutralise the directional bias.

Why this direction for a bedroom?

Like the master, secondary bedrooms need cross-ventilation, controlled light, and visual privacy. For children's rooms, a south-facing study desk under the window works well; for guests, a small mid-sill window is sufficient.

Vastu's ideal placement for a bedroom is W, NW. North-East is outside the traditional band, though with simple remedies the room works well.

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-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

Bunk beds beneath a low window — falls through glass risk
Bedroom window directly opening into a neighbour's kitchen view
Air-conditioner installed in the only ventilation window
Treating North-East placement as a hard error — it's not. The room remains usable; a small Vastu remedy (heavy furniture on the W wall, mirror placement away from the bed) handles the directional refinement.
