Glass: A viable circular commodity

The majority of construction glass goes to landfill because the industry has not established the knowledge and procedures to divert this precious and carbon-intensive commodity back into the supply chain. As with all materials, the journey to reuse starts with identifying the glass within a building to understand what can be accepted as cullet back into the float manufacturers' furnaces. The panel will guide you through the entire process of assessment, removal and remanufacture illustrated with the first significant examples of construction glass recycling taking place over the next months.

Mainstreaming novel regenerative materials: Challenges and solutions

Some novel nature-based materials have been around for millennia but have fallen out of mainstream use, while others are entirely new and innovative. The regenerative capability of new nature-based construction materials may be well-documented but it doesn’t automatically follow that a regenerative product can be brought into the supply chain.

How do we identify and overcome the stumbling blocks in insurance, warranties and other barriers?

Metropolis: Mass Timber hybrid extension delivering high-value workspace

Metropolis is the deep retrofit of the Woolworth’s HQ building designed by Richard Seifert. Designed to be net zero in operation the project has also saved an estimated 25,000 tonnes of embodied carbon through building retention, mass timber extension and fossil-free fuel in operation.  Delivering an exceptional product to future occupiers, the design incorporates around 15% amenity space including gardens, roof terraces, shared amenities and end of journey facilities . Come and hear from the team on the particular challenges faced to achieve the project including:

• improvements to building fabric while retaining as much of the historic facades as possible 
• the design, approvals and insurance procedures needed to build out of exposed mass timber
• delivering amenity-rich, sustainable workplaces for occupiers

UK Retrofit: What can we learn from the US?

In 2019 New York City adopted a unique piece of legislation called Local Law 97 setting out operational GHG emission limits for all buildings in the city, both new and existing.  A first of its kind internationally, the standard sets maximum emission levels by building program and type, which become progressively stricter until 2050, and sets fines for non-compliant owners. As the law comes into effect in 2024, hear from NYC design and engineering experts on the implications of meeting these requirements and the effects they are having on development, covering:

• the history and development of Local Law 97, and what it requires from buildings
• its effect on the approach to design being taken by developers, institutions and the building industry in general
• its relation with energy code requirements and voluntary certifications like LEED
• its specific impact on the development of key ongoing projects

Measuring Scope 3 carbon in fit out

Businesses are being encouraged to monitor and disclose the results of their carbon emissions, despite the absence of a current legal obligation, highlighting a pressing need for action. For contractors, Scope 3 emissions will likely account for 95%+ of carbon emission so there is no route to Net Zero without tackling Scope 3.

In this session we will explore, with those who have done it, the process of measuring true Scope 3 in the construction industry. Panellists will talk about how about their personal experience tackling the measurement of Scope 3 in their organisations, offer practical guidance and offer a call to arms for the industry to embrace the Scope 3 challenge.

Concrete: Developments in the supply chain

There are myriad concrete technologies in development around the world, but the majority of these are at the laboratory stage and not ready to deploy. In this session we cover three of those that have made it to the supply chain: GGBS, limestone fines, and calcined clays.

GGBS is a finite resource. What should developers and specifiers know about making the best use of the limited supply to drive down the carbon emissions of concrete?

Limestone fines and calcined clays are abundant resources. They can be used separately or in combination (as "LC3") to deliver carbon savings on a similar level to a high-GGBS mix concrete. Some concretes using these can achieve as much as a 50% lower carbon footprint than ordinary "CEM I" concrete. What are the realities of using these products in the UK and what is the potential to scale production to meet demand?

Building with Nature: An opportunity for construction and society

The built environment is a net consumer of materials and a major contributor to climate change. Future generations are concerned about how current decision-makers are seeking to address this, and many children are already considering what their role might be in the future to make a positive contribution.

MMC offsite timber-frame houses delivering on performance, cost, quality and carbon reduction

Countryside Partnership’s development in Hemel Hempstead will deliver 445 low carbon homes. Spencer’s Park is also being used as a monitoring site for Category 2 MMC closed panel timber frame, providing evidence on the benefits of offsite manufacturing, not only for a safer, more pleasant working environment for contractors, but a more environmentally friendly and sustainable solution than more traditional masonry builds.
