U Value Calculator now available on iOS, Android & Windows phone!
Finally after months of development and testing, our U value calculator app UValue is released on Apple iOS as well as Android and Windows Phone.
Below are a few screen grabs that show the key features:
• Scalable high resolution graphics for all phones and tablets
• Ability to enter your own materials, thicknesses and conductivities as opposed to searching in scrolling lists
• Calculates for floors, walls, roofs and ceilings and adjusts the interior and exterior thermal resistance values accordingly (in accordance with DIN EN 6946 Section 5, Chart 1.)
• Available on Android, iOS & Windows Phones
• Includes settings for underground wall, rain screen or warm/cold roof constructions
• Information/settings screen
• Ability to reset all values or delete individual lines
• Adheres to Passivhaus methodology of calculating U values (excluding thermal bridging – see below)
• Links to TeachPassiv.com and additional Passivhus resources, news & FACT SHEETS
• This version totally free of charge
Why did we create the app? I was looking for a simple U value app that gave the ability of quickly entering data, allowed a quick comparison between different constructions/insulation and supplemented the PHPP U value calculations (the app is not intended to replace PHPP). I found that the app didn’t exist and we (myself and my coding maestro son Conor) decided to fill the gap in the market.
The app is free of charge and is used as a marketing aid for TeachPassiv.com and the architecture and Passivhaus Design Practice Mark Stephens Architects
The app does not currently take account of thermal bridges, this is going to be addressed in a subsequent version.
If you find any bugs or inaccuracies in the app, please do not hesitate to contact us at firstname.lastname@example.org
You can read the Privacy Statement regarding the app HERE
The app is not supported or endorsed by the Passivhaus Institute, does not replace the U value calculations in PHPP and is for entertainment purposes only e&oe.
A big shout out to my sons own website who is a Games Coding Guru at GreenCheeseGames.com

This article concurs with the article posted by Kate de Selincourt last year for Passive House Plus magazine that explains how the perception that Passive House is more expensive has come about.

It should be remembered that both pieces of research are UK based and that in Ireland (where the Building Regulations are much closer to Passive House standards), the cost saving differential is much greater.
