Summer Comfort Statement
To ensure summer comfort, Passivhaus certification requires written documentation of the strategy for thermal comfort in summer, signed by the building owner. This should be issued to the building certifier as part of the certification documentation, alongside the relevant section of the handbook for the building user.
The sample Summer Comfort Statement provided here has been put together by the Passivhaus Trust and the UK Certifiers Circle to be used as a template for this purpose. 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.
