Try the physics yourself.
Free tools from our building physicists, worked out live in your browser. They show what changes when a design changes. They don’t predict a rating or replace an assessment: for that, send us the plans.
- ClimateNCC and NatHERSClimate labType a suburb or postcode to see its NCC and NatHERS climate zones, its climate in numbers, and what usually works in a design there.
- WallsR-valuesWall labPick a wall system and change what a builder would. See its R-value with the studs counted, and how it handles a hot or cold day in any climate zone, facing any way.
- Embodied carbonA1 to A3Carbon labBuild a single-storey home and see the upfront carbon in its floor, walls, roof and windows, beside the same home in double brick.
