Get ready for CIBSE Build2Perform Live 2023

The building services industry’s premier event includes, for the first time, the Light2Perform symposium and CABE’s Building Environment Live. Alex Smith picks out some highlights from the packed two days of discussions and learning

A packed theatre at last year’s CIBSE Build2Perform Live

The eighth CIBSE Build2Perform Live will return to ExCeL London on 5-6 December 2023, with 125 speakers, 100-plus exhibitors, and more than 70 hours of presentations and debates, covering every facet of the building services industry.

For the first time, the event will incorporate Light2Perform, with an extensive programme curated by the Society of Light and Lighting (SLL) and the Lighting Industry Association. Also co-locating with Build2Perform Live is the Chartered Association of Building Engineers’ (CABE’s) Built Environment LIVE, which has themes of performance, compliance and safety.

A CIBSE-accredited CPD programme will run alongside Build2Perform. Curated by CIBSE Divisions and Special Interest Groups, and the Build2Perform Live advisory committee, it will feature invited specialist speakers from across the built environment.

Build2Perform’s key themes this year are heating for net zero, climate adaptation, electrical services, smart technology, building safety, and health and wellbeing. 

Build2Perform key themes

  • Delivering net zero and adapting to climate
  • Hydrogen, heating and heat pumps for net zero
  • Electrical services for a zero carbon environment
  • Adopting digital tools and smart and secure technologies
  • Implementing the building safety reform programme
  • Health and wellbeing

Net zero, safety and overheating

The keynote session on day one will discuss how the UK Net Zero Carbon Buildings Standard will impact environmental design. This will be followed by an session on virtual, augmented and virtual realities, which will delve into artificial intelligence and discuss the benefits and pitfalls of handing building control to the machines. 

Representatives of the government and the Building Safety Regulator (BSR) will explain how the Building Safety Act is revolutionising the way buildings are procured, designed and maintained. Building safety is also the theme of a session organised by the Society of Façade Engineering. 

Thermal comfort is key to health and wellbeing, and Build2Perform will feature a session on the latest research and industry developments in assessing overheating in buildings. Speakers include Kevin Lomas, Susie Diamond and Becci Taylor. 

On day two, the keynote will cover CIBSE’s TM65: Embodied energy in building services, and look at TM65 guides specifically for Middle Eastern and North American regions. 

Winners of the annual Society of Digital Engineering Awards will also be announced at Build2Perform. 

The CIBSE Resilient Cities Group is hosting a seminar on advances in urban digital planning and modelling for climate-resilient and healthy cities, and other sessions will look at indoor air quality and guidance on avoiding mould and damp. 

In the CPD theatre, the CIBSE Lifts Group, with Adam Scott, will present on the whole life carbon of lifts, while Nick Mellor, of the Lift and Escalator Industry Association, will discuss building safety and the evacuation and use of lifts by firefighters.


Key themes of Light2Perform include emergency lighting, external lighting, dark skies light pollution, decarbonisation, health and wellbeing, regulation, and sustainability. 

The conference will feature the launch of LG7 Lighting for offices and LG14 Control of electric lighting, and the Young Lighter of the Year competition will be announced.

Light2Perform’s technical programme will cover ever-tighter eco-design requirements and the challenge of reducing embodied carbon, and has been organised by leading lighters Bob Bohannon, Sophie Parry and current SLL president Helen Loomes.

The BSR’s deputy chief inspector of buildings, Chris Griffin-McTiernan, will give a keynote at Build2Perform Live, and there will be sessions on fire safety, new-build housing quality, building retrofits, and zero carbon building performance.

The event is a fantastic opportunity to network and be on top of all the huge changes happening in building services as we strive for net zero and building safety. The Journal hopes to see you there.
