Climate intelligence for the Global South
We decode any planfor lower bills and longer life.
Vāstav reads any floor plan for light, air, heat and comfort, then hands you the changes that pay back the most. Vastu is optional. Leave it off and lose nothing.
We spend a lifetime’s savings on a home. Yet we have almost no way to know how it will perform.
What a report reads
A space, measured on every axis that decides how it feels.
Idle. The plan is at rest.
HeatWhich walls cook your rooms at 4pm, and which face takes the summer.
Air & lightWhy one bedroom never breathes, and where the daylight actually lands.
MoneyWhat your plan costs you every year, and the fixes that pay back first.
Vastu, read as climate and geometry. One optional chapter, on only if you want it. How we read →
Every reading shows its evidence. Each becomes a change you can make, ranked by cost and return.
Tradition is one layer here. Never a belief you must hold.
Vastu is a single optional chapter, read as climate and geometry. Turn it off and lose none of the science.
Why it matters
A building quietly decides your comfort, your bills and your health.
Heat
A home that traps the afternoon runs cooling all night. Orientation, shade and mass set the bill before the AC does.
Water
Cities have already rehearsed day-zero rationing. A home that catches and reuses its rain stays resilient.
Air
Rooms with no light or cross-breeze hold stale air. How a home breathes is a question of health, not just comfort.
Good building has always answered with orientation, mass, shade and air. Vāstav measures how well yours does, and what helps most for the least.
This week’s climate fact
Terracotta evaporative cooling can lower the air around it by 6-8°C using only water and fired clay.
As water seeps through porous clay and evaporates, it pulls heat out of the passing air. Try a terracotta evaporative panel or water body on the windward side of a hot room.
A new fact lands here every week.

Notes on light, air, heat and orientation.
The quiet centre: why the middle of a home should be left to breathe
In classical planning, the centre of a building is not a room. It is a pause.
16 May 2026Climate3 min readWhy one room in your home is always too hot
The afternoon sun is entirely predictable. Most floor plans treat it as a surprise.
12 May 2026Perspective4 min readVastu was never superstition. It was climate memory.
Strip away the fear, and what remains is a remarkably good environmental brief.

Building intelligence for a warming world.
India once built for climate. We are rebuilding that intelligence as a living network: the techniques, the materials they are made of, the places that taught them, and the proofs that they still work.
