Course Overview

Overheating risk is now a critical compliance consideration for UK residential buildings. This course provides a clear, practical introduction to assessing overheating using the IES Virtual Environment (IESVE), in line with Approved Document O and CIBSE TM59. It is suited to practitioners who need an overview of compliance requirements and how these are supported within VE workflows.

You’ll explore the key drivers of overheating risk and the design strategies commonly used to mitigate it, alongside an overview of the regulatory and technical context behind Part O and TM59. Through guided demonstrations, the course shows how to assess overheating risk in IESVE, review results against TM59 criteria, and support Part O submissions using the VE Navigator.

This course provides a high‑level overview of Part O and TM59 rather than detailed methodological training. Learners are encouraged to consult the relevant guidance documents for full technical and regulatory requirements.
