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 support@teachpassiv.com

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.

Does Passivhaus meet the Building Regulations? @phplusmag @BRegsBlog mentioned

MARK STEPHENS ARCHITECTS

I contributed THIS OPINION PIECE to the BregsForum last year concerning Part L compliance of the Building Regulations. In it I said:

“The only way numerically (currently) to assess conformance with Part L of the Building Regulations is via the Dwelling Energy Assessment Procedure (DEAP) software. It is this software that allows the user to input the following:

Property Details
Property Dimensions
Ventilation details (Chimneys, ventilation type, air tightness etc…)
Building elements (Construction types, u values areas etc…)
Water heating
Lighting
The software on completion can give conformity results on U-values, renewables, primary energy use and CO2 emissions. The conformity with the Building Regulations is given in a straightforward green check (tick) or red cross. “

According to a recent article in passive house+ magazine this advice has now been superseded. In the article Dr Brian Motherway, the CEO of Sustainable Energy Authority of Ireland (SEAI) states:

“SEAI does…
