Window Orientation Planner
Tell us which way the wall faces, your climate and the room, and get the best window type, glass and shading — plus a four-direction solar-comfort comparison. Indicative India 2026 design guidance; sun angles vary by latitude.
Your wall
Climate: Balanced: maximise north/east, shade south, control west.
Living / studio: Wants generous, even daylight and a view — north and south shine.
Scores are indicative solar-comfort ratings (0–100) for India. In cold hill stations the rules flip — a sunny south window becomes an asset for winter warmth.

Window types
Large fixed / picture or casement — open it up; this is the prized studio light.
Glass
Clear, high-VLT glass (single or plain DGU). No solar control needed — you want every lumen.
Shading
Minimal. A light pelmet or sheer is enough; no chajja required for heat.
Size guidance
Go large — north glazing rarely overheats, so maximise the opening.
Sun: Steady, glare-free diffuse daylight all day — almost no direct sun, no heat gain.
