Planetary health and human health are inseparable—and our solutions have to be, too. Climate change, public health, business resilience, and productivity are not separate challenges—they are deeply intertwined. That is why the future of buildings is not about choosing between priorities, but about integration.
Buildings offer one of the greatest opportunities we have to deliver health benefits at a large enough scale to resemble public-health intervention, while simultaneously advancing climate, innovation, and resilience goals. Nowhere is this truer than in the long-overdue pairing of indoor air quality with energy efficiency and broader sustainability improvements.
Fortunately, buildings are a natural place for this kind of convergence. Modern buildings are dynamic systems. Heating, ventilation, filtration, and conditioning already shape the air we breathe every day—whether we are paying attention or not.
When indoor air is invisible—when there are no measures, no monitoring, no accountability—we have no way of knowing how clean or healthy it is.
This is why the future of buildings depends on doing things simultaneously. Improving indoor air quality cannot be treated as something separate from energy efficiency. These solutions must move together, and they must make financial sense. The good news is that, in many cases, they are already moving together, and we can accelerate those good best practices.
The conventional wisdom that better indoor air requires sacrificing energy performance no longer holds up. Today’s technologies allow us to improve ventilation, filtration, and air quality while also reducing energy use. Smart controls, energy-efficient equipment, better building envelopes, and real-time automated data-driven building management systems make it possible to achieve both outcomes at once.
Policy is beginning to catch up with this reality. The European Union’s latest Energy Performance of Buildings Directive explicitly pairs energy performance with indoor environmental quality, recognizing that buildings must serve both people and the planet.
The benefits of this integration extend well beyond compliance or environmental metrics. When buildings save energy, they save money—that has long been clear. Buildings that invest in health deliver returns that are just as powerful: higher productivity, stronger workforce performance, better retention, and an enhanced ability to attract top talent. For organizations competing in a tight labor market, these outcomes are strategic advantages.
What draws so many of us to the building sector is precisely this opportunity to do more with buildings. To address climate challenges. To be resilient in the face of a changing and more volatile climate. And, increasingly, to consider and help protect health.
This convergence is not accidental, it is necessary. And the business case is clear.
As commissioners on the Global Commission on Healthy Indoor Air, our charge is to ensure that progress does not happen in silos, and that health is never positioned as a tradeoff against climate action. We know unequivocally that energy performance and human health can—and must—rise together.
Through the Commission’s signature work this year to develop a Global Framework for Action, we are carrying forward a simple but powerful truth: Buildings can advance environmental sustainability and human health side by side. Leading owners, designers and operators are already proving this is not only possible but also delivers ROI. Our task now is to make these integrated solutions the norm rather than the exception.
Healthy indoor air is not the opposite of high performance. It is the proof of it.
And if we activate the right levers—policy, market signals, and shared accountability—our buildings can become what they were always meant to be: engines of health, resilience and sustainability.
