PHT Coffee Morning: PHPP questions answered with Coaction

The Passivhaus Trust and Coaction Training are pleased to launch a 3-part expert Q&A series of interactive PHPP support sessions for Passivhaus Trust members and Coaction alumni.

Whether you are working through your first PHPP model, refining your workflow, or tackling a more complex project, these informal online discussions provide an opportunity to bring your questions directly to experienced PHPP practitioners.

Each one-hour session will focus on a specific theme, and participants will be invited to submit questions in advance. Our expert hosts will prioritise pre-submitted questions and aim to answer as many as possible during the discussion.

Designed as practical, interactive learning sessions, these events provide an opportunity to learn from common challenges, explore different approaches and gain confidence in your use of PHPP and DesignPH.
