Sustainable architecture for hospitals: the future of healthcare infrastructures in 2025
Architecture is much more than designing and constructing buildings: it is the art of creating spaces that respond to human needs, combining functionality, durability and beauty. Throughout history, this discipline has evolved together with society, adapting to the challenges of each era. Today, one of those great challenges is sustainability.
In this context, sustainable architecture has ceased to be a trend and has become a necessity. More than a passing fad, it represents a profound change in the way we conceive, plan and execute construction projects. Its approach seeks a balance between energy efficiency, respect for the environment, economic viability and social well-being. This vision has begun to transform multiple sectors, including one of the most critical: healthcare.
With the accelerated growth of cities and the need to strengthen services in smaller communities, the hospitals of the future must go beyond technical efficiency.
Today, the construction of healthcare infrastructure implies an unavoidable environmental responsibility. Incorporating sustainable solutions is not only desirable, but essential to reduce environmental impact, preserve natural resources and respond to climate change.
Why is it so important to apply these principles specifically in hospitals? How can sustainable architecture redefine hospital design and why is it key to the development of health systems that are more resilient, humane and committed to the planet?
The healthcare sector: an expanding field with high sustainable potential
In recent years, the healthcare sector has acquired strategic relevance, driven by the ageing population, technological innovation and the growing demand for quality medical care. This scenario not only generates opportunities for social development, but also for responsible and sustainable investment.
Unlike other sectors, healthcare has proven to be dynamic and resilient, ranging from research and biotechnology to the production of medicines, supplies and medical devices. Within this chain, hospital infrastructure plays a crucial role, as it is the space where people’s care is materialized. However, its development has often neglected the principles of sustainability, when in fact it should be leading them.
Investing in sustainable hospitals not only makes economic and social sense, but also responds to an urgent need: to create spaces that care for both patients and the planet.
Comprehensive well-being: how good hospital design cares for the patient and the environment
A hospital should not only be efficient in medical terms, but also in its ability to provide a healthy environment. Air quality, ventilation, natural lighting, acoustics and the distribution of space are factors that directly affect the well-being of those who inhabit it. However, one of the most critical—and frequently ignored—elements is the choice of construction materials.
Many of the materials traditionally used for construction emit volatile chemical compounds that affect indoor air quality. Although their effects may not be immediate, prolonged exposure can have serious consequences: from allergies and headaches to reproductive disorders and certain types of cancer. These effects also affect the emotional health, stress and performance of healthcare personnel.
Cases such as sick building syndrome, sensitivity to Wi-Fi networks or intolerance to electromagnetic fieldshighlight the need to design truly healthy spaces. And if this is important in any building, in a hospital it is unavoidable.
Sick building syndrome
This term describes a set of symptoms experienced by people spending time in certain buildings. It manifests itself in discomforts such as nasal congestion, loss of voice, irritation of the respiratory tract, dry skin, headaches or fatigue. The most striking thing is that these symptoms usually disappear shortly after leaving the affected building.
The causes are usually related to poor ventilation, the use of low-quality or toxic materials, the presence of mold, the accumulation of chemical pollutants and inadequate air conditioning. In many old hospitals, these factors are still present, compromising the health of those who inhabit them.

Currently, although there is research on materials and indoor health, the information is often fragmented. Therefore, there is an urgent need to adopt a comprehensive approach that considers human health as the central axis of hospital architectural design.
Sustainable hospitals in Spain: examples that lead the way
In Spain, several hospitals are leading the change towards a more environmentally responsible healthcare infrastructure. Examples such as the Hospital del Mar in Barcelona or the Hospital 12 de Octubre in Madrid have opted for sustainable construction models that seek to meet the needs of the present without compromising those of the future.
These projects have implemented a series of concrete strategies to minimize their environmental footprint, including:
- Significant reduction of CO₂ emissions.
- Use of more environmentally responsible materials.
- Integration of natural spaces, both indoors and outdoors, that improve the well-being of patients and staff.
- Reduction of waste and efficient waste management.
- Development of eco-efficient energy infrastructures, with a clear focus on reducing energy consumption.
Energy efficiency has become a key pillar of sustainable hospital architecture. It is not just about the work of architectural firms in the intelligent design of lighting, air conditioning or ventilation systems. The role of hospital equipment and technology suppliers is also essential.
From electrical safety to medical and non-medical equipment, each component influences the overall energy footprint of the building. These factors, in addition to reducing long-term operating costs, directly improve the comfort and health conditions of patients, professionals and visitors. Fortunately, this is an aspect that is gaining increasing prominence in decision-making within the healthcare sector.
