The built environment is undergoing a fundamental shift. With rising pressure to reduce carbon emissions, improve energy efficiency and create healthier, higher-performing buildings, the way we design, specify, construct and operate buildings is changing rapidly.
Taking place on 25-26 November 2026 at ExCeL London, elementalLONDON brings together the professionals, technologies and ideas driving this transformation. Focused on HVAC, energy efficiency and building performance, the event provides a dedicated platform for those responsible for improving the way buildings perform, from design and specification through to installation, operation and retrofit.
Co-located with London Build Expo, the UK's leading and largest event for construction and design, elementalLONDON creates opportunities to connect building performance specialists with the wider construction and built environment community.

Three pillars driving building performance
elementalLONDON is built around three core pillars: HVAC, Energy Efficiency and Building Performance. Together, they reflect the interconnected challenges facing the industry and the practical solutions needed to create more efficient, resilient and comfortable buildings.
HVAC
Heating, ventilation and cooling are central to the performance of buildings, with the industry facing increasing demand for systems that are more efficient, adaptable and capable of supporting decarbonisation.
elementalLONDON will bring together manufacturers, engineers, consultants, specifiers, contractors and building owners to explore the latest developments across heating, cooling, ventilation and controls.
The programme will examine topics including heat pumps, heat networks, low-carbon heating, smart controls and future-ready HVAC, while addressing the practical challenges involved in delivering high-performing systems across commercial, industrial and large-scale residential buildings.
Energy Efficiency
Improving energy efficiency is essential to reducing operational emissions, managing costs and supporting the UK's transition to net zero.
Across the event, visitors will discover technologies, strategies and approaches designed to improve energy performance, from building controls and energy management systems to retrofit, renewable technologies and more efficient heating and cooling solutions.
The Climate Solutions Theatre will explore these themes through sessions addressing decarbonisation, future building standards, overheating, energy systems and climate adaptation. The Sustainability Arena, delivered in collaboration with London Build, will broaden the conversation to include embodied carbon, circular construction and wider approaches to sustainable development.
Building Performance
The final pillar brings together the different elements required to ensure buildings perform effectively throughout their lifecycle.
From indoor air quality and occupant comfort to digital monitoring, building management and operational performance, elementalLONDON will explore how buildings can be designed and managed to deliver better outcomes for both people and the environment.
CIBSE Build2Perform Live will form a key part of the programme, bringing together engineers, consultants, manufacturers and policymakers to explore the future of building services and high-performance buildings.
A programme built around practical solutions
The elementalLONDON conference programme will bring together experts from across government, engineering, construction, property and building services.
Sessions in the Climate Solutions Theatre will explore topics including “Decarbonising London”, “Future Buildings Standards: The Prospects for Commercial Buildings” and “The Battle Against Overheating: Why Cooling Has a New Urgency”, addressing some of the most pressing challenges facing building owners, designers and operators.
The event will also provide opportunities to explore the latest products and technologies directly from more than 200 exhibitors spanning heating, cooling, ventilation, energy management and building systems.
Visitors can expect to meet established manufacturers, specialist solution providers and emerging innovators, creating opportunities to compare technologies, discover new approaches and build relationships across the supply chain.
Connecting the building performance community
elementalLONDON is designed to bring together the full ecosystem involved in improving building performance, including architects, engineers, MEP professionals, facilities managers, contractors, developers, building owners, local authorities, housing providers, consultants, manufacturers and policymakers.
With dedicated networking opportunities, facilitated meetings and informal spaces for discussion, the event provides a platform to share knowledge, develop new partnerships and learn from peers working on similar challenges.
The event will also benefit from its co-location with London Build, giving visitors access to the wider construction and design community. A free ticket provides access to both events, including 25,000+ attendees, 650+ exhibitors, 900+ speakers across 17 CPD-accredited conference stages, networking events, interactive workshops, live demonstrations and specialist features such as the Architect's Hub.
Whether you are looking to improve building performance, specify more efficient systems, explore the latest HVAC technologies, understand the changing regulatory landscape or connect with the organisations driving the UK's energy transition, elementalLONDON provides two days of insight, innovation and collaboration.
elementalLONDON takes place on 25-26 November 2026 at ExCeL London. Registration is free and provides access to both elementalLONDON and London Build.
