The statement identifies the critical assumptions that underpin the design, and the summer comfort strategy, as well as overheating risk results and stress testing.This template can also be used for buildings with active cooling, presenting the expected results for active cooling instead of overheating risks.|2024|**[[https://www.passivhaustrust.org.uk/|Passivhaus Trust (PHT), UK]]** |

In these cases the Passivhaus Certifier may require a dynamic thermal modelling risk assessment in addition to correct input of the PHPP calculation.This guidance from the UK Certifiers’ Circle aims to establish a common approach to modelling, reporting and user handover in these scenarios.|2023|**[[https://www.passivhaustrust.org.uk/|Passivhaus Trust (PHT), UK]]** |

As a comfort driven approach, the Passivhaus standard includes a summer overheating criterion which requires that internal temperatures do not exceed 25ºC for more than 10% of the year. However, as with all models, the assessment is highly dependent on the assumptions that are made during the modelling process. We need to ensure that the result remains robust when those assumptions vary, for example as occupant behaviour changes, or as the climate warms.|2021|**[[https://www.passivhaustrust.org.uk/|Passivhaus Trust (PHT), UK]]** |
