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 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.

A big shout out to my sons own website who is a Games Coding Guru at GreenCheeseGames.com

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

I wrote this earlier today on whether Passivhaus meets Part L of Building Regs

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…

Passivhaus is cheaper than standard build @encraft_uk @Kate_de @phplusmag mentioned

A recent study by Encraft shows that taking into account the whole life cost of a house, Passive House construction is 2-5% lower than traditional construction methods.

CLICK HERE for the article and HERE for the full article.(788kb)

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.

CLICK HERE for the post & link to article by Kate de Selincourt

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.

TeachPassiv.com 2014 in review

The WordPress.com stats helper monkeys prepared a 2014 annual report for TeachPassiv.com.

Here's an excerpt:

A San Francisco cable car holds 60 people. This blog was viewed about 3,100 times in 2014. If it were a cable car, it would take about 52 trips to carry that many people.

ps A good start and hoping to do a lot more next year, stay tuned…

#Passivhaus trickle-down on ‘Standard’ projects

I put this together on MarkStephensArchitects.com last week…

MARK STEPHENS ARCHITECTS

What I’m seeing over the last few years is that even if the client doesn’t go the ‘whole enchilada’ with a certified Passivhaus (I would however highly recommend designing, building and certifying to the Passivhaus standard incidentally); many of the Passivhaus features are becoming incorporated and ‘trickling down’ to the ‘Standard’ project. Namely:

1. High levels of insulation.

200mm cavity (before insulation) with low conductivity wall tie 200mm cavity with low conductivity wall tie

With the ‘optimal’ cavity width for Passivhaus certification using concrete blocks at 300mm (pumped with platinum multi-bead insulation); we’re frequently adopting cavities on our ‘Standard’ projects of 200mm and 250mm.

2. Minimal Thermal bridges

As you can see in the image above, we are using low conductivity wall ties instead of steel versions.

The photo below also shows the low-conductivity blocks we use in strategic locations to reduce thermal bridging:

3. Triple Glazing

The price for triple glazing in Ireland has reduced…
