There is nothing like owning a fully certified passivhaus. It’s the ultimate in comfort and energy efficiency. But just because you can build a passivhaus doesn’t mean you must, or even should.. Most passivhaus builders won’t tell you this, but the truth is: You can enjoy 90% of the benefits of a passivhaus , without the full cost of passivhaus certification.
How To Get Passivhaus Comforts Without The High Cost
Passivhauses are designed and constructed around five critical pillars:
- Airtightness
- Mechanical heat recovery/ventilation
- Insulation
- Glazing
- Thermal Bridge
For your home to be certified as a passivhaus , it must meet rigorous standards in all of these areas. But that doesn’t mean you can’t build a supremely comfortable and energy-efficient home that falls just short of being certified as a passivhaus . In fact, you can enjoy most of the benefits and save $50,000 or more. The key is to follow at least three of the five pillars.
The Most Important Passivhaus Pillars For A Comfortable, Energy-Efficient Home
If you’d like most of the comforts of a passivhaus , without the price of formal certification, simply forego airtightness and mechanical heat recovery ventilation. While these features give you ultimate flexibility and control over the comfort of your home, you can achieve almost the same benefits as long as you’re prepared to ventilate your home manually (i.e. open the windows once a day).
In areas of variable weather (like the Adelaide Hills), window glazing is almost an expected feature (and cost) so it’s not really adding to your budget. Insulation is also a familiar inclusion (which you can save money on with a slightly thinner material without significant loss of performance). And eliminating thermal bridges has more to do with the skill of the builder than the cost of building materials.
So, focusing on these three pillars will give you most of the benefits of a passivhaus without some of the cost.
Naturally, if you want the ultimate (and when you’re investing a seven figure sum on the home of your dreams, there’s a case for getting exactly what you’ve always wanted), there’s nothing like a formally certified passivhaus .
