HLM unveil Highland Passive House
HLM have unveiled a low energy passive house in the Highland village of Gorstan, Ross-shire, which blends traditional features with the latest energy consumption and emission standards.

Tigh-na-Groit consumes 80 per cent less energy than standard builds, achieved by careful consideration of form and orientation to minimise heat loss and maximise solar gain.

Ross Barrett, associate director at HLM, said: “We think that this house best represents our ethos and mission to shape the built environment towards a more sustainable future as it tackles the problems of fuel poverty and carbon emissions in the most effective way: by minimising energy consumption.”

Other features include insulation with no thermal bridging, airtight fabric and mechanical ventilation with 90 per cent efficient heat recovery.

Apologies, there was a mix-up with the photography. Correct visuals are now attached.

Nice considered architcecture but mechanical ventilation at domestic scale?

Does the house comply with Passivhaus design standards or is the use of the description 'passive house' just a claim to low energy consumption

#5academicviewer. Passive House design is generally based around an OCD level of attention to air tightness. Over and above aspect, solar gain etc, you end up with a hermetically sealed box. This requires mechanical ventilation, which is usually a highly efficient heat recovery unit too, to provide the required ventilation, without throwing open a window when it's minus 10 outside. On a domestic scale, they are small, quiet, and energy efficient.

That said, i sleep with the window open 12 months of the year. Can't stand a warm bedroom.

Air tight buildings are a pointless exercise in a domestic situation in Scotland. They are not conducive to pleasant living environments and are really part of this generations "ego" driven fetishistic culture that tack on "sustainability" onto any building. Not needed.

Never mind those vanguardist eco-warriors at HLM out there trailblazing the path for the rest of us (and for whom we are all truly grateful), but Timelord's suggestion of 1952 set me thinking of Morris and Steedman Associates' much more recent Clachaig House/Home? Or, am i looking at the same building group in a previous life? I'm confused. It's a slow day...

@ 9
Should we assume from that that you don't believe in scientific principles?
An air tight building just allows for controlled ventilation. Of course it's a more sustainable method of building and of course you can create whatever internal climate you like whilst still adhering to that principle - it's actually easier to do so.

#6 seems it was passive house certified earlier this year https://twitter.com/HLMArchitects/status/610411096864915456

30% of carbon emissions worldwide are caused by buildings...can't keep blowing hot air out of the windows & leaky building fabric forever.

Talking about hot air, 34% of methane emissions, contibuting more significantly than carbon emissions to global warming come out of cows backsides. What can architects do here?
