• Provide technical advice and sustainability guidance during project meetings, design reviews, and client discussions.
• Support planning applications, regulatory submissions, and compliance strategies.
• Contribute to the ongoing development and enhancement of building physics and sustainability services.
• Prepare technical reports, calculations, and supporting documentation to a high professional standard.
