Summer Comfort Statement

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.

PHPP is a proven tool for assessing overheating risk and already deemed to satisfy Part O of the Building Regulations (England & Wales) by several Building Control services. This position paper argues that it should be accepted as an alternative means of compliance for single family dwellings and simple building forms.

Dynamic Thermal Modelling

For multi-residential or non-residential buildings the single zone steady state PHPP calculation is sometimes not sufficient to effectively evaluate summer comfort and overheating risk during design for individual zones. 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.

Avoiding summer overheating

Recent summer heatwaves have made us more aware than ever that the risk of overheating in both new and existing buildings demands attention – and is likely to become even more of a concern as our climate warms. 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.

Technical Guidance - Designing for summer comfort in the UK

This guide addresses the emerging concern of building overheating in the UK and presents a recommended design approach for ensuring summer comfort in domestic dwellings up to four storeys high, aligning with Passivhaus principles.
