What is the ideal window size for a north-west-facing bedroom in Chandigarh?

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 bedroom in Chandigarh. Type: Sliding 2T. Glazing: clear.

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

Yes — North-West is the ideal Vastu direction for a bedroom. Vayu (Vayu (Air)) governs this direction, and the room aligns naturally with that energy.

Why does Chandigarh's composite climate need clear glazing?

Chandigarh 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 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.

Why Chandigarh's climate matters

Chandigarh 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.
