What they mean for design, construction and compliance
Free SEES Technical Webinar | October 2026 | 12:30–1:30 pm | Microsoft Teams
Parts L, O and F of the Building Regulations cannot be considered in isolation. Decisions affecting energy efficiency, overheating and ventilation are increasingly interconnected, and getting them wrong during design can create significant problems when a project reaches construction, testing and completion.
Join SEES for a free one-hour technical webinar looking at the practical application of Parts L, O and F and what architects, developers, contractors and consultants need to consider throughout a project.
Rather than simply working through the regulations, we’ll look at how the requirements affect real projects, where compliance issues commonly arise and what can be done during design to avoid problems later.
What we’ll cover:
- Part L – energy efficiency and achieving compliance
- Part O – overheating risk and its impact on building design
- Part F – ventilation, commissioning and testing
- How Parts L, O and F interact
- Key decisions and information required during design
- The implications of specification and design changes
- Common issues encountered during construction and completion
- Carrying design assumptions through to the finished building
- Practical steps that can reduce the risk of late-stage compliance problems
Who should attend?
This webinar is aimed at:
Architects | Developers | Contractors | Design Managers | Technical Managers | Planning & Design Consultants | Construction Professionals
Whether you’re responsible for designing a building, developing the specification or actually constructing it, the session will help you understand what the requirements mean in practice – and why decisions made in one area can have unintended consequences elsewhere.
Your presenters:
Naomi Sadler – Director, SEES
Naomi has over 25 years’ experience in construction and 18 years specialising in sustainability, energy and building performance. She works closely with design and construction teams across Building Regulations compliance, energy assessment, thermal bridging, overheating, ventilation, air tightness and wider building performance.
Muhammad Ali MSc MCIBSE – Sustainability Engineer
Muhammad specialises in building performance and sustainability, working with architects, developers and contractors on the practical application of energy efficiency, overheating and ventilation requirements.
