Sustainable Buildings: Making of a Greener and Regenerative Future

Sustainability

Greening the construction industry has become a priority, but it isn’t clear whether the transition represents a profitable investment opportunity. The Klosters Forum 2023 attendees unveils this enigma.

From homes and offices to roads and power installations, the built environment has long been a magnet for private investment. 

 

But as investors now realise, the techniques used to construct vital infrastructure are no longer sustainable; the real estate sector alone accounts for around 40 per cent of global carbon emissions. 

 

Greening the construction industry has therefore become a priority. But it isn’t clear whether the transition represents a profitable investment opportunity. 

 

This was the conundrum that delegates at this year’s The Klosters Forum set about resolving. 

 

During three days of intense discussions, developers, investors, architects, entrepreneurs and academics challenged the building industry’s established practices and explored how new technologies and tougher regulations could bring about a sustainable transition. 

Towards regeneration

Kicking off the event was an interactive workshop on “Net Zero Buildings: financing the transition towards a climate neutral built environment”. 

 

Delegates heard how traditional building techniques cause irreparable harm to the environment, damaging land, water and biodiversity – which are among the key environmental dimensions as identified by the Planetary Boundaries (PB) model. 

 

The PB is a globally recognised sustainability framework developed in 2009 that defines the environmental thresholds within which humanity can survive, develop and propser.1 

 

“We need to understand the Planetary Boundaries for urban development,” said Rasmus Nørgaard, co-founder of Danish developer Home.Earth and a board member of NREP, the largest real estate fund manager in the Nordic countries.

 

Many agreed that net zero, or carbon neutral, was not ambitious enough. Instead, the building industry – and investors in the sector – should take a lead in not only preventing damage but also repairing and restoring what has been lost to unchecked urban development.

“We’ve caused so much deterioration in the environment that we need to explore the concept of regeneration,” Steve Freedman, head of research and sustainability in Pictet Asset Management’s Thematic Equities, told the workshop.

 

Götz Hilber, co-founder of Rematter, a Zurich-based start-up providing sustainable building materials, said: “We have to switch our mindset from reducing our negative footprint to increasing positive impact.”

 

“If you decrease something bad, you are always less bad. That’s a frustrating message to humanity… We also don’t want to be neutral. We want to be positive.”

How to shrink the footprint

While investors in infrastructure may agree on the need for change, they often face challenges in finding projects that meet their environmental objectives, conference attendees were told. 

 

By the same token, developers and entrepreneurs, find it hard to obtain large-scale financing for what are sometimes ambitious projects with novel approaches to sustainability, resilience and inclusion. This yawning gap in financing represents a significant barrier to the sustainable transition.

 

Nørgaard presented a promising example in Denmark which has overcome such challenges. In Copenhagen, Home. Earth is building sustainable and affordable homes and communities that have a smaller environmental footprint, enhance the quality of life for residents and turn a profit.

 

Currently, buildings that are considered among the most sustainable in the market2 have carbon emissions of roughly 11 kg CO2 per square metre per year in Denmark, nearly 10 times more than the limit set by the Planetary Boundaries.3

 

Adopting circular and regenerative practices such as reusing wood, Home. Earth’s first residential development had a carbon footprint of just 5 kg – a new record for this class of building in Denmark.4

 

Home.Earth development also helps reduce a floor space a resident occupies – thus contributing overall to a smaller carbon and resource footprint. 

 

On a per capita basis, an average Dane occupies roughly 59 square metres. In Home.Earth designed homes, this figure nearly halves to 25-30 sqm per person on average. This means that Home.Earth development with regenerative practices has the potential to demonstrate that new housing can be developed within the PB framework. 

 

What is more, the development has an ambitious social agenda, including the redistribution of returns to not just shareholders but also tenants.

This stakeholder income model – which is becoming a common feature in sustainable building projects in developed economies — helps attract more loyal tenants and build a strong community and social foundation – thus tackling a weak link in real estate ESG investing.

 

“If you engage meaningfully with a broad range of local stakeholders and empower them, you can help build trust and in return gain permission to proceed with the project. This becomes a virtuous cycle,” said Paul King, managing director of sustainability and social impact at real estate firm Lendlease Europe.

 

Building trust across local communities is a particularly urgent issue for planners. When it comes to planning large-scale development, just 2 per cent of the public trust developers and only 7 per cent trust local authorities, according to a 2019 study by UK-based property firm Grosvenor Group.

 

“We need to build a deep, long-term investment partnership to shift a colossal gap in financing,” King said.

Spatial justice

Another novel approach to plugging the financing gap in sustainable urban development is spatial justice.

 

This, TFK conference attendees heard, was first proposed by influential US urban planner Edward Soja in 20105, who argued that all city dwellers should have equal rights and access to resources, services and access.

 

Under this approach, interest rates, property values and taxation would take into account a property’s environmental and social credentials.

Currently, residents and the local community shoulder the cost of a building’s environmental degradation rather than the developer or owner.

 

Progressive taxation and insurance mechanisms should therefore incentivise a shift in capital allocation in favour of buildings that promote greater public good, such as low carbon, clean air and green space. In doing so, asset owners and managers would be encouraged to invest in the long-term resilience of the portfolio, rather than to extract purely financial returns.

 

Specifically, wealth taxes and rewards for ecological and energy efficient building projects were some of the options discussed; including environmental risks as a key insurance gauge was another.

 

“People carry the financial consequences of living in a bad building… We need a shift in investment from extracting returns to investing for long-term resilience,” one participant said.

What is The Klosters Forum?

The Klosters Forum is a not-for-profit organisation, offering a neutral platform for disruptive and inspirational minds to tackle some of the world’s most pressing environmental challenges. Its mission is to accelerate positive environmental change by developing and nurturing a growing community of leading thinkers and doers and by fostering cross-disciplinary exchange and collaborations.

 

Every year, the Forum hosts an environmental annual event connecting high-profile participants from the fields of science, business, politics and industry, as well as NGOs, creative minds and sustainability experts in a neutral and discreet environment. This year, the annual forum took place on 27-29 June 2023 with the theme “The future of the built environment.”

Pictet’s partnership with The Klosters Forum

The Pictet Group is pleased to partner with The Klosters Forum to draw attention to the impact of real estate on our environment and to contribute to the conversation about this important issue.

 

As stewards of global capital, we are able to withhold or withdraw capital from businesses that fail to take their environmental responsibilities seriously. In our view, whilst today’s environmental debate tends to focus primarily on climate change, investors now need to pay as much attention to their impact on biodiversity as they do to their carbon footprint. Our investment teams have substantial experience in this area through the pioneering range of sustainable and thematic investments they manage.
