How a Building meets the Passivhaus Standards
Takumi Sloan • Dec 12, 2019
With the increase of low energy buildings its crucial to understand how a building can meet a standard like Passivhaus:
- It must have an annual heating and cooling demand of no more than 15
- The energy used to generate electricity must not exceed 60
- The air changes per hour must not exceed 0.6@ 50 Pa. Moreover, the air changes per hour must also be tested once the membrane is built and must achieve below 0.6 to ensure it’ll achieve 0.6 at final build.
- The summer overheating must not exceed 10%
If these criteria aren’t met then a building can qualify for other standards like PHI Low Energy Building, EnerPhit or AECB Building Standard.

Homes in the UK are at increased risk of overheating, which is worsening with climate change. This affects comfort and health of occupants, especially during night. Overheating is mainly caused by design of the houses, in particular large glazing areas and non-openable windows. To address this, Building Regulations Part O introduces two methods for compliance: Simplified Method, or comfort criteria under thermal modelling using CIBSE’s TM59 (with some additional requirements set by AD O). This blog focuses on the Simplified Method.
The government have recently closed the Future Homes and Building Standards 2023 consultation on 27 March 2024. There have been two consultations into the Future Homes Standard, both of which proposed a draft of measures for new and existing homes. Most of the key takeaways from the recent consultation are in regard to new homes and non-domestic buildings. A small number of sections are also relevant to existing buildings, such as Material Change of Use buildings. The standards will build upon the recently introduced changes to Approved Document Part L 2021. This consultation provides a glimpse into what we can expect from later consultations, regarding the Future Homes Standards to be implemented in 2025.
