The second instalment of Net Zero Live for 2022 is taking place on 22 & 23 November. Across the two days we will be taking a look at how to address some of the biggest challenges firms in the built environment are facing when it comes to decarbonisation.

Join us as we explore the challenges around the performance gap, specifying to meet regulations, and the role infrastructure has to play.

Closing the performance gap

The performance gap is a well-known issue within the construction and housebuilding sectors but one that will continue to hinder efforts to reach net zero if not addressed. In this session we will look at the ways in which the project team can look to reduce the performance gap in both residential and non-residential buildings.

Our panel of experts will discuss factors that contribute to the performance gap and how this hinders sustainability efforts. We will also look to explore how designers and constructors can overcome these hurdles and the role different parts of the supply chain play in addressing issues around building performance.

COP27 lessons learned: What did it tell us about decarbonising our existing estates? 

With COP27 taking place in November, the construction and engineering sectors will be looking to Egypt to find out what the latest thinking will be on issues such as decarbonisation, progress on net zero targets and the role finance can play in supporting industry to achieve its sustainability goals.

This session will look at the key outputs of the conference and specifically what it means for the retrofit market and the decarbonisation of the existing built environment.

Speakers include:

Chair: Jordan Marshall
Special projects editor
Assemble Media Group
Thomas Worthington
Principal sustainability and carbon consultant
Annabel Clark Regional director, sustainability lead Faithful+Gould

Keynote – Part Z: An industry proposal for embodied carbon regulation in the UK

In this keynote presentation join Will Arnold, head of climate action at The Institution of Structural Engineers, as he discusses the industry proposal to regulate embodied carbon in the UK.

Will is a fellow and staff member of The Institution of Structural Engineers, leading the institution’s response to the climate emergency and embedding sustainability action into all aspects of its work. He is responsible for driving the update of minimum standards for institution members, producing supporting guidance, and leading collaboration across the wider industry. 

Will leads the work of the Part Z initiative, chairs the CIC’s 2050 Group, and sits on the Steering Groups for both the UK Net Zero Carbon Buildings Standard and the Built Environment Carbon Database. In recognition of his work instigating change in the field of structural sustainability, Will holds the IStructE President’s Award, and the Memcom Outstanding Achievement Award.

Specifying for Part L

Updates to Approved Document L, or Part L, of the Building Regulations for England, came into force on 15 June 2022. The updated regulations aim to lower the operational carbon emissions of new homes, raise fabric efficiency standards and introduce a new level of quality control.  As such specifying materials and products to meet the new standards has become a top priority and consideration in the past six months.

In this session, hear from a panel of experts as they outline what the fabric requirements are, explain the specification responsibilities from a Part L perspective, and how decisions can impact compliance. The panel will also discuss which specification decisions can have the biggest impact on energy efficiency and what the cost implications and benefits are both during the build and post-occupancy.

Speakers include:

Chair: Hollie Tye

Net Zero in the built environment: From ambition to action

Global infrastructure demand is insatiable, but climate change calls for lower emissions. As we look at COP27’s ambition to move from pledges to action, there will be an even greater onus on how the construction industry can help take on both challenges, and play a lead role in making net zero happen.

This will require an accelerated shift towards not just innovative green solutions and processes but radical new ways of sustainable thinking in everything from transport and logistics, local sourcing, community engagement and biodiversity as the industry continues to redefine modern construction practice. The panel will explore the key sustainability developments that will aid this transition and the benefit of staking the opportunity to go greener now.

This session will cover the sustainability agenda, key outcomes of COP27 and construction’s role as a key driving force, the current state of play, and what needs to be done.
