Technical Guidance - What it means to claim Passivhaus in the UK

Category: Guidance

Within the UK, there are occasionally claims that buildings meet or exceed the Passivhaus standard simply because they might meet one or more of the Passivhaus requirements. Forexample they achieve the air-tightness target, or utilise insulation levels that are akin to theminimum backstop U-values, or have been shown to have a space heating energy demand of less than 15kWh/(m2.a) using other energy calculation tools such as SAP. It is incorrect to claim that such a building is a Passivhaus building unless it can be shown to be designed and constructed according to all the certification criteria.

This paper provides guidance on quality assurance measures that are required to meet the Passivhaus Standard in the UK.
