Sustainability, understood as the ability to meet present needs without compromising those of future generations, is based on a balance between three fundamental pillars: environmental protection, social equity, and economic responsibility. This concept has gained global relevance, driven by the United Nations Sustainable Development Goals (SDGs), which provide a clear framework for promoting fairer and more environmentally respectful practices.
In the field of sustainable building, the aim is to minimise the environmental impact of construction, optimise resource use, improve energy efficiency, and ensure a healthy environment. This is achieved through the design, construction, and operation of buildings that meet strict sustainability criteria. Certifications such as LEED, BREEAM, VERDE, WELL Building Standard, and PASSIVHAUS are tools that assess and validate the environmental performance of buildings, setting a global standard.
