5 Principles of Passivhaus

PassivHaus is a premium quality building standard recognised throughout the world for energy efficient building design that also promotes indoor comfort, health and acoustic insulation.

How does a Passivhaus work?

The standard is founded on five principles that combine to reduce energy use:

Does a Passivhaus home need heating?

Passivhaus homes are built to minimise heat losses and optimise thermal gains from glazing. This results in a Passivhaus home requiring 90% lower energy than that of other buildings. Passivhaus homes therefore don’t need anything like the traditional specification of home heating systems, such as boilers. Instead, they can easily use renewable energy sources like solar panels or heat pumps to supply their heating requirements.

Are Passivhaus homes expensive?

Even though Passivhaus homes and buildings require high-quality building materials and construction, they are still surprisingly affordable. As products and Passivhaus building techniques continually improve, construction costs are approaching the same level as traditional builds.

Thus, the long-term savings on energy bills ensure Passivhaushomes are a great investment.
