Technical Guidance - UK Climate Data

Category: Guidance

The UK has 22 climate data sets which are included within the Passivhaus Planning Package (PHPP). These datasets are used in all certified Passivhaus buildings within the UK. The datasets have been generated using ‘Met Office’ data and ratified by the Passivhaus Institute.

Additional data sets are now also available from the following weather stations: Northolt, Swansea, Charterhall, Oban, Inverness, Skye (Lusa) and Wick. Please contact your certifier if your project is in one of these areas.

Please note: The auxiliary calculation within PHPP is recommended for countries lacking detailed climate data, and should not be used for UK certification. For more information please contact your building certifier.
