What is the ideal window size for a west-facing dining room in Delhi?

Vastu and composite climate together suggest a window approximately 2.5 feet wide with a sill height of 3.5 feet on a west face for a dining room in Delhi. Type: Fixed + Vent (top hopper). Glazing: clear.

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

Yes — West is the ideal Vastu direction for a dining room. Varun (Prithvi (Earth)) governs this direction, and the room aligns naturally with that energy.

Why does Delhi's composite climate need clear glazing?

Delhi 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 Delhi's climate matters

Delhi 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 west face in this climate, the recommendation is a fixed + vent (top hopper) window with clear glazing and a sill at 3.5' — calibrated for hot summers, cold winters, and seasonal monsoon.
