Benefits of component certification

Passivhaus Certified Component

The Passivhaus and EnerPHit standards are characterised by very high energy savings compared with standard construction. This is achieved by highly efficient building systems, careful planning and very efficient components. As a rule of thumb, these components can be two to three times more efficient than other commonly used products. This high level of efficiency is critical to achieving the standards.

It is often difficult for the designer to assess the energy-efficiency, durability and the necessary energy parameters of a component as the available standard parameters are frequently unrealistic or are not accurate enough; reliable project planning using manufacturers’ information alone is often not possible.

As an independent authority, the Passivhaus Institute in Darmstadt, Germany, tests and certifies products in respect of their suitability for use in Passivhaus and EnerPHit developments. Products that carry the Certified Passivhaus Component seal have been tested according to uniform criteria; they are comparable in terms of their specific values, and are of excellent quality regarding energy efficiency. Their use facilitates the designer’s task and contributes significantly to ensuring the faultless functioning of the resultant Passivhaus.
