UK project teams.
* Attend remote design and coordination meetings, providing clear and informed technical input.
* Produce accurate modelling outputs and concise technical reports for review by the UK team.
* Contribute to both retrofit and new-build projects across a variety of sectors.
Skills & Experience
Applicants are not expected to meet every requirement, and additional training and support can be provided.
* Proven experience in building physics and IES VE modelling.
* Experience undertaking overheating, thermal comfort, and energy performance assessments.
* Strong understanding of UK building regulations and sustainability standards, particularly Part
L, Part O, and TM59.
* Experience contributing to Energy Strategy Reports or similar sustainability documentation.
* Ability to work independently in a remote environment while maintaining effective
communication with UK-based teams.
* Previous experience working on UK building projects would be advantageous, but is not
essential.
* Knowledge of SAP, SBEM, or Elmhurst software would be beneficial, although candidates with
strong IES and building physics expertise will also be considered.
Whats on Offer?
* Long-term freelance engagement.
* Fully remote working from South Africa.
* Opportunity to work on a wide range of UK building projects.
* A technically focused role centred on building physics and performance modelling.
* Exposure to both retrofit and new-build developments.
* Supportive and collaborative UK team environment.
