Home design · with the physics included
Most home design apps stop at how a room looks. Tiang runs real simulations on the plan you drew — temperature, humidity, electricity and WiFi — using actual weather for your location.
Free to draw and save, always. Android.
Drag the divider. The same house twelve hours apart.
Each one runs on the geometry you drew and the materials you chose — not a generic template of a house.
Which rooms overheat, how hard the air-conditioning has to work, and what a day looks like hour by hour.
Where moisture collects and where condensation is likely — the rooms that grow mould before you notice.
Yearly consumption, what panels would generate on your roof, what a battery changes, and when it pays back.
Signal in every room, with your walls actually attenuating it. Move the router and watch the dead spot close.
Furniture apps help you picture a room. Tiang tells you what that room will do in August.
No CAD experience needed. Most people get their first simulation in about ten minutes.
Drop rooms, drag walls to size, cut in doors and windows. Snapping keeps everything square, and the 3D view builds itself as you go. Or import a PDF or photo of a plan you already have and let Tiang trace it.
Pin the building on the map and turn it to face the right way. That one step is what lets the sun land where it really does, and pulls the right weather in.
Pick a date and hour, then run it. You get a field you can rotate, per-room numbers, a timelapse across the day, and a PDF you can hand to a builder.
Open-Meteo, for the exact coordinates you pinned. Past dates use recorded history. Dates up to about two weeks ahead use the forecast. Beyond that the app falls back to a seasonal estimate, and it tells you on screen which of the three you are looking at.
Accurate enough to compare options, which is what it is for — this wall build-up against that one, the router here against there. It is a design tool, not a certified energy assessment, and every screen shows the assumptions behind its numbers.
No. Tell it which country you are in and Tiang fills in typical wall, roof, floor and door build-ups for you — a rendered block wall under a vented roof in Jakarta, a cavity wall in Manchester, a deep timber frame in Stockholm. If you do know the details, you can edit every layer.
Drawing, editing and 3D all work with no connection. Simulations need one, because the weather and the heavier calculations come from the server.
Not yet. Tiang is Android for now.
