SUSTAINABLE HOSPITAL DESIGN
and strategies. The former, comprising greenery and shading devices, help to reduce carbon and heat gain from the sun, specifically during the summer months. This technique is employed by the Santa Fe de Bogotá Foundation (Fig. 2), with its indoor greenspace/solarium and the unique brick pattern of its façade, which serves as a passive filter, controlling the amount of sun rays that enter depending on the space, and, ultimately, the amount of heat gain. The New Karolinska Solna (Fig. 1), on the other hand, relies on more active systems and technologies. It uses a ‘combination of district heating, remote cooling, a separate geothermal plan, plus recycled energy from ventilation air’,3

different parts of the hospital. The New Karolinska Solna also leverages pneumatic tubes and AI-powered robotic carts that transport supplies via a dedicated elevator system, with no disruption to other hospital activities. The use of drone delivery services is expected to become more widespread in the near future, as more and more facilities begin adopting the technology.
Advanced technologies, notably AI,
are becoming integral to the healthcare industry, facilitating a smarter use of resources, and improving sustainability. It’s worth highlighting that the hospital of the future will operate on the basis of reducing its energy consumption with the aim of reaching Net Zero. This can be achieved by using both passive and active sustainable design technologies
Gold certification, with 99.7% of its energy drawn from renewable sources. Healthcare facilities should adopt a combination of passive and active sustainable design techniques to reduce their carbon footprint and tackle the challenge of climate change effectively.
A holistic approach to the hospital of the future The hospital of the future will need to achieve the objectives of sustainable development in full to guarantee health alongside social, economic, and environmental sustainability. This will see numerous aspects of the architectural
