There comes a point when the future is no longer distant.
We have reached it.
The past few months of extreme heat, persistent droughts, fatal wildfires, torrential rain, collapse of glaciers and devastating floods have rocked countries and communities across the world. Another year in which the realities of climate change continue to hit home. The climate crisis is already here.
At the same time, the world around our buildings is being reshaped by a profound energy and technological transition. Smart electrification is expanding, digital systems are changing how energy is generated and used, and markets and regulation are evolving with them.
Yet much of the building stock on which we depend was designed for a different climate, a different energy system and a different economy, while the buildings we are financing and constructing now will still be standing well beyond 2050.
So, we face a defining choice: are we building for the world we have known — or for the world our buildings actually need to operate in?
This World Green Building Week, taking place 7-11 September, our message is clear: let’s #BuildItReady.
#BuildItReady is more than a campaign. It defines the buildings we now need: able to withstand what is happening — and ready for what comes next.
These qualities cannot be confined to flagship green projects. They must become the standard across every home, office, school, hospital, warehouse and public building.
We do not have to choose between environmental responsibility, human wellbeing and commercial value. Ready buildings bring those outcomes together: improving health and comfort, embracing circular economy principles, strengthening resilience to climate risk and creating lasting value for businesses, people and future generations.
Crucially, we know how to deliver this. Proven technologies, design approaches, standards and business models are already demonstrating what ready buildings can achieve. The challenge is to make those solutions the norm.
The shift to clean electricity is already reshaping the infrastructure that powers our communities.
Renewables, batteries, electric technologies and intelligent digital systems are becoming increasingly interconnected — an electrotech revolution with transformative potential for buildings.
But expanding renewable generation and strengthening grids is only half the task. The other half is demand: ensuring buildings can use clean electricity efficiently and flexibly.
We cannot build a clean energy system without making the buildings connected to it ready, too.
Combining efficiency and electrification with on-site generation, storage and smart controls changes the role buildings can play. They move from passive consumers of energy to active participants — reducing pressure at peak times, making better use of renewable power and potentially generating and storing energy themselves.
That is smart electrification.
Delivery will require investment in grids and buildings, retrofit finance, skilled workers and supportive policy. Every market will follow a different route. But the direction is clear, and much of the work — design, installation, renovation, maintenance and optimisation — will happen locally, creating skills and employment in the communities where the transition is delivered.
The reward is a new generation of better-performing assets, stronger energy systems, skilled local employment and economies less exposed to the shocks of an uncertain world.
Imagine what becomes possible when readiness spreads across neighbourhoods, cities and countries?
At scale, building readiness becomes climate resilience, energy resilience and economic resilience.
That scale can transform lives. A resilient built environment could help protect the 85% of the world’s population already affected by climate change.
Building equitably could help provide adequate homes for more than one billion people living in informal settlements, while efficient and accessible buildings and energy systems could help lift 2.8 billion people out of energy poverty.
Buildings and construction already support more than 200 million jobs worldwide, while embracing circularity across the built environment could help unlock up to US $4.5 trillion in economic benefits by 2030.
These are not separate policy aspirations. They are connected outcomes of the same choice: to make the places that shape our lives fit for the realities ahead.
That is the proposition at the heart of World Green Building Week. We are not simply calling for more exemplary green buildings. We are demonstrating what becomes possible when readiness moves from the margins of the market into the mainstream.
What gives me confidence is that this is not an abstract vision.
Across WorldGBC’s network of more than 80 Green Building Councils and over 51,000 member companies, businesses and industry leaders are already translating readiness into action.
The diversity of activity on this year’s World Green Building Week events map shows what that looks like in different markets.
This is just a snapshot of the incredible initiatives of our GBCs and partners across the world. These are different approaches because readiness cannot mean an identical blueprint imposed everywhere. A building in Cairo will not face the same risks, energy system or market conditions as one in Helsinki, Hong Kong or Bogotá.
Different climates. Different markets. Different challenges.
But one shared direction: making our buildings capable of performing in the world we live in today, while adapting to the one taking shape around us.
The scale of action across our network sends a powerful signal as attention turns towards the UN Climate Summit COP31 in Antalya this November. Positioned by its Presidency as both an Implementation COP and a COP of the Future, the summit places electrification, circularity and resilient cities among its Action Agenda priorities, with ambitions to accelerate global electrification and reduce energy intensity across the building sector.
COP31 offers an important opportunity to move the needle: to recognise the built environment as essential infrastructure for turning these ambitions into action.
The world we need to be ready for is not decades away. It is already here.
We cannot predict every climate shock, technological shift or economic opportunity the coming decades will bring. But we can make decisions today that leave our buildings — and the people, businesses and communities that depend on them — better prepared.
Ready for a changing climate.
Ready for a clean, increasingly electrified energy system.
Ready for new economic and social realities.
Ready for opportunity.
This World Green Building Week, let’s #BuildItReady.
