The benefits of properties with stronger sustainability profiles are now so demonstrable that both buyers and tenants are willing to pay a premium for them. Advances in building materials and technology mean the real estate sector is taking the lead for investors looking to harness the transition theme.
The scope for change – and investment – are considerable. The built environment is responsible for around 40 per cent of Europe’s energy consumption.1 This is not a figure that can be simply cut to nothing; buildings will always need power to function. But our offices, homes, and commercial buildings – many of which date back decades or even centuries – are not always using power in the most effective way or taking advantage of the latest technology. Around 75 per cent of buildings across the European Union are energy inefficient.2
Realising their potential can be relatively straightforward – and it does not mean knocking down our cities to start again. After all, demolition and construction are the most carbon-intensive stages of a building’s life cycle. Renovating an existing asset creates 60 per cent less embodied carbon compared to building something new.3 Add the latest technological innovations and the amount of carbon needed to operate the building can also be reduced to zero.
What does that look like? There are the basics: installing improved insulation, adding more efficient LED lighting, heating, ventilation, and air conditioning systems to reduce the power a building needs. But a building can also generate its own – green – power. Rooftop solar panels or wind turbines, or replacing traditional gas and oil-powered boilers with air-sourced heat pumps, can end the reliance on carbon-based fuels.
Then there are the new technologies in development that offer exciting glimpses into the future. The creation of fully transparent photovoltaic panels could soon mean that every window in an office or home can generate solar electricity. Innovations in sustainable materials and their manufacture such as carbon-negative cement, green steel produced without the use of fossil fuels, or even mycelium bricks made from organic waste and fungi fibres, could all play a part in reducing carbon in construction. Given that concrete production is responsible for up to 8 per cent of global carbon dioxide emissions, any improvements here would have a dramatic impact.4
Ahead of the curve
The European Union estimates that renovating all of its inefficient buildings to be more sustainable could reduce the region’s total energy consumption by 5 to 6 per cent.5 It’s an ambitious figure, but individual projects demonstrate the extent to which an asset’s energy footprint can be cut if remodelled with power efficiency in mind. Take for example a central London office block that’s currently undergoing such a remodelling. This is not an old, crumbling, brown building: this is an asset originally built in the early 21st century, but a mere twenty years on we’re in a position to improve radically its energy efficiency. Upgrading its facilities with many of the technologies listed above will reduce the primary energy demand of the building by more than 75 per cent. On completion, the building will be capable of operating at net-zero carbon, with no reliance on fossil fuels at all.
All of this technology puts the real estate sector ahead of the curve for the energy transition. Although not every building has a heat pump installed or a network of solar panels lining its roof yet, this is only because of a lack of capital or management foresight. That capital may be on the way though. Because sustainable buildings are still relatively scarce in Europe – less than 20 per cent of offices across big European cities have a green certificate6 – there is an attractive green premium on offer for those buying into the sector.7 One report showed that total returns for efficient buildings in the 12 months to Q2 2023 were 1.2 percentage points higher than for inefficient buildings, with the differential growing to 3.2 percentage points between inefficient and efficient offices.8
Tenants are also willing to pay more to rent sustainable buildings: almost three quarters of corporate real estate decision makers say they are likely to pay a premium to occupy an office with green credentials, with over half planning to do so by 2025.9 Similarly, around two thirds of occupiers renting logistics facilities such as warehouses are planning to be net zero across their property footprint before or during 2030.10 While a green building may cost companies more to rent, their energy efficiency can mean that operating bills are less, reducing their overall spend on occupying the real estate.
Taking the weight
The process of investment and renovation must accelerate if climate goals are to be met. Some 80 per cent of existing commercial real estate in the European Union needs updating to become more efficient,11 although only 1 per cent of buildings in the region undergoes energy-efficient retrofits each year.12
Increasing the pace of renovations even by a small amount would significantly cut the energy used by real estate. Given that other industries will find it harder to reduce their reliance on fossil fuels, accelerating improvements in this sector could help with reaching net zero targets even as other sectors fall behind. In addition, if our buildings can cut the amount of energy they use, the aggregate demand for renewable electricity could come down. This would offset the growth in demand from other industries that are unable to cut their energy usage as quickly – an increasing concern given supply constraints – while also helping to alleviate the pricing pressure for those more difficult-to-abate sectors.
The targets laid out by the Paris Climate Agreement are moving out of reach, and the time frame in which we have to take action is narrowing. Those sectors that have the capacity to implement change – including real estate – should do so in earnest, and welcome the wave of investment that follows.
