We bring the smartest minds in the property carbon-reduction world to FOOTPRINT+, so we think it’s only right for us to disseminate all this experience and knowledge freely. Most of what you hear here won’t have been spoken about before; it’s all hot-off-the-press! If you were at FOOTPRINT+ 2026, you can hear all the talks you couldn’t get to while you were in another of our 6 theatres; and if you weren’t, now is your chance to learn why you need to be at FOOTPRINT+ 2027.

One Exchange Square reimagines a 1980s office building and demonstrates how novel methods can be used to expand commercial floor space on a large-scale cut & carve project whilst minimising carbon impact. The whole building has been redesigned to deliver healthier working environments with roof terraces, interior planting and a diversity of uses contributing to a revitalised whole.
The project delivers a substantial 11-storey, 7.5m extension above London Liverpool Street Station without foundation strengthening, avoiding the significant embodied carbon associated with new basements and deep piling. An exoskeletal transfer truss and hanger system redistributes loads back to the retained structure, enabling 94% structural retention by volume, prioritising flexibility and material efficiency. Preloading the structure and removing it as the facade was installed minimises movement of the cladding system.

Investor approaches to greening real assets span a wide spectrum—from doing the bare minimum to comply with regulation, to deep retrofits designed to meaningfully reduce climate impact. This session explores what truly matters to investors across this range of ambition and how differing priorities shape capital allocation, asset design, and operational decisions. We examine how owners, developers, lenders, and asset managers weigh cost, risk, return, and reputation when assessing sustainability strategies, and how these considerations translate into real-world outcomes for the built environment.
The discussion will also tackle:
- Has political fatigue dampened sustainability momentum or simply reshaped it?
- The sentiment divide differences across Europe, UK and US capital?
- How occupier demand, leasing behaviour, and willingness to pay influence investment decisions and long-term asset value?

Is it possible to remove mechanical heating and cooling systems entirely while still providing comfort?
Buildings today are increasingly designed around mechanical systems rather than people. Comfort is routinely solved through equipment, driving complexity, cost and carbon. Heating, ventilation and air conditioning systems alone can account for over 15% of construction budgets, often exceeding the cost of the façade, while remaining energy-intensive to operate and carbon-hungry to manufacture and maintain.
- How far can design intelligence go before mechanical systems are truly required?
- What do people actually need to feel comfortable?
Challenging the practice of designing for rare climatic extremes that dictate system size for the entire year, and by understanding how temperature, air movement and adaptive comfort interact, NowtHaus explores buildings that perform naturally year-round. The outcome is a passive office building with no conventional heating or cooling. Peak heating loads remain below 5 W/m², allowing internal gains to maintain winter comfort, while natural ventilation and thermal mass regulate summer conditions. The team behind the concept will demonstrate how this approach simplifies construction and reduces cost.

Much to the annoyance of linguists, Will Arnold argues that regenerative design is a verb, not a noun. It's a process we can all follow - on any project - to move us closer to the goal of doing more good with construction, rather than just minimising harm.
In this keynote, Will will share a simple process he has developed to anchor all the amazing innovations, processes and mindsets that exist in industry today, and draw them together into a regenerative approach to building design and construction.
Learning from examples taken from across the industry, see how his three pillars of systems thinking - place, time and influence - can be combined to create buildings that heal our planet.

Energy Performance Certificates (EPCs) have shaped the non-domestic built environment since their introduction in 2008 and, despite ongoing criticism, are clearly here to stay. While EPCs are often challenged for relying on simplified and sometimes outdated assumptions, overlooking factors such as heritage constraints and offering only a broad view of building performance, they continue to exert significant influence on investor confidence, tenant demand and asset value. This session explores whether EPCs are the right tool to drive progress towards net zero and, crucially, how they can be used more effectively.
Panel members will discuss how EPC assessments are approached in practice, the transformative impact of Minimum Energy Efficiency Standards (MEES), and recommended pathways for ongoing improvement. The discussion will cover practical measures to improve ratings, including the role of commercial heat pumps, and the differing levels of retrofit required to reach target ratings. Real-world case studies will demonstrate how office buildings can be upgraded from EPC ‘E’ to ‘A’ or ‘B’, contrasting deep retrofits in vacant buildings with the challenges of working in occupied spaces.

Workplace Futures Group shine a light on the impact of CAT A fitouts within construction. The session will provide real world data on the impact of CAT A fitouts, reviewing waste, carbon and cost impacts created in the move from landlord to tenant ownership. The panel will also discuss examples of ways our design and site teams can reduce their impact, and showcase the innovative new technologies which also may be the answer for CAT A waste.

Respecting materials is essential to credible circularity in construction yet current legislation fails to demand low-carbon or post-consumer metals. This gap is expected to close as policy evolves but progress on such regulation is slow.
Using the example of a central London office retrofit this discussion will focus on the principles that shaped its low‑carbon strategy, the successes and learnings. The discussion explores why respecting materials is essential to credible circularity, and how current legislation fails to demand low‑carbon or post‑consumer metals; a gap expected to close as policy evolves. The panel will cover the challenges of downcycling, particularly where, once downcycled, aluminium alloys can never be upcycled again, and the need to maintain high material quality, highlighting the importance of closing the loop, reducing waste and treating metal as a resource we are all responsible for stewarding.
