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.

Energy performance is where the net-zero retrofit challenge will be won but only if ambition is matched by delivery. Using Tower Bridge Court (TBC.London) as a live case study, this panel explores how one of London’s first all-electric, net-zero carbon retrofit workplaces translated energy ambition into measurable operational performance through building systems.
Bringing together the developer, architect and engineering perspectives, the discussion examines how energy targets were defined early, embedded into design, and delivered in practice. From all-electric strategy and operational energy performance to embodied carbon reduction and occupier wellbeing, the panel focuses on the decisions that mattered and the trade-offs that shaped the outcome.

The Portman Estate’s relocation of its head office to One Great Cumberland Place presented an exciting opportunity to reimagine the workplace. The project aims to set a benchmark for sustainable commercial interiors across its 110-acre Marylebone estate.
The retrofit of the 8,400 sq ft office prioritises collaboration, wellbeing, and exemplary environmental performance while working within an existing base build. Sustainability informed every design decision including:
- Low-carbon and high-recycled-content materials
- Circular economy principles resulting in reuse of existing services, lighting, and finishes
- Inventive reuse of salvaged materials
- Specification of furniture to meet rigorous environmental, repair, and replacement criteria
Embodied carbon was measured and recorded to support The Portman Estate’s One Planet Action Plan, achieving carbon neutrality with minimal offsetting and setting a replicable benchmark for future workplace retrofits.

So what is Regenerative Design?
Regenerative design is increasingly discussed across the built environment sector, yet it is often unclear what it means and how it differs from other sustainability practices within construction.
This session will provide a concise, accessible introduction to what regenerative design is, what it aims to do, and why it can’t be reduced to a checklist.
Drawing on insights from the Regenerative Design Lab, a cross-sectional learning programme for built-environment professions, the speakers will share what emerges when people work with regenerative principles over time and what it means for practitioners trying to make change today.

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.
