What is the ideal window size for a north-east-facing pooja room in Lucknow?

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 pooja room in Lucknow. Type: Sliding 2T. Glazing: clear.

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

Yes — North-East is the ideal Vastu direction for a pooja room. Ishan (Jal (Water)) governs this direction, and the room aligns naturally with that energy.

Why does Lucknow's composite climate need clear glazing?

Lucknow 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 pooja room?

A pooja room window's job is to bring morning light to the deity at dawn — small, high-sill, and on the NE wall ideally. The window should never face directly at the deity but rather light the side wall, creating soft fill light during morning aarti.

Vastu's ideal placement for a pooja room is NE — North-East sits in this band.

Why Lucknow's climate matters

Lucknow 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.
