The Passivhaus Standard

The Passivhaus Standard informs a unique and highly effective approach to design and build from the outset. It ensures everything conceived and constructed is not only unique and compelling, but also considers and applies a range of factors to achieve optimum energy efficiency and climactic comfort.

See the bigger picture

You might say it’s basic physics, and you’d be right. But these underlying principles are so often ignored – either in the rush to construct and turn a profit, or simply not seen as important as design aesthetics.

Why live in a tent?

It’s now widely accepted that many developers will apply ‘temporary fixes’ to ensure their creations pass airtight testing, and that standards will therefore have probably dropped considerably by completion and sign-off. Some independent research on air changes in new-builds has described airtightness as comparable to that of a tent!

The Passivhaus Standard seeks to put an end to this, as it requires less than 0.6 air changes in an hour, compared to the usual 10. It’s a tough target, but it’s crucial in terms of energy efficiency and comfort, as air leaving the property generally takes heat with it.

Remarkable energy savings

In short, intelligent ‘fabric-first’ design and build principles are paramount in achieving the energy-efficiency and living comfort the Passivhaus Standard demands. And not just for new-builds – why not apply the same to extensions or renovations, achieving far greater insulation and air-movement standards with new windows and structural junctions? Either way, selecting the right materials and installing them with careful detail can help you achieve heating energy bills 90% lower than average.
