U Value Calculator

The U value calculator is brought to you by www.TeachPassiv.com A Passivhaus initiative by Mark Stephens, Architects, Passivhaus Designers and App developers.
The app calculates U values of materials and construction assemblies using the Passivhaus methodologies and calculations.

The app calculates U values for Walls, Floors, Ceilings and Roofs and allows you to input your own materials rather than searching for them in a table and takes account of underground & rain screen construction.

Developed for iOS and Android, the U Value Calculator also gives resulting Rse and Rsi thermal resistance values (interior & exterior) in accordance with DIN EN 6946 Section 5, Chart 1.

The app is not supported or endorsed by the Passivhaus Institute, does not replace the U value calculations in PHPP and is for information purposes only e&oe.

Disappointing. The app opens and when selecting an option, it crashes. Also the interface has a children's app feel.
