About this event

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.

To meet this need, the Passivhaus Trust has developed a PHPP plugin accompanied by detailed guidance covering design strategies to reduce risk, limitations and constraints that may have an impact, key indicators of the likelihood of risk, and a series of stress test to demonstrate robustness.

This short course explains the guidance in detail and teaches you how to use the PHPP plugin.

Delivered by John Palmer, Research and Policy Director at the Passivhaus Trust and author of the guidance and PHPP plugin.


The content is delivered as two pre-recorded video modules plus a live online workshop, which will give you the opportunity for in-depth Q&A with John Palmer and a review of what you've learned.
