Knowledge Bases

How to Build a Passivhaus UK Knowledge Base

The UK Passivhaus Knowledge Base is a new database that has been developed by the Passivhaus Trust. It acts as a unique reference source about products, systems and approaches that have been used on certified Passivhaus buildings.

The information included in the database has been written and peer-reviewed by leading experts in the industry. It is connected to and initially based upon the ‘How to build a Passivhaus' guidance document that was first published by the Passivhaus Trust in April 2015.
