As the world grapples with the challenges of climate change and the need for sustainable solutions, the concept of net-zero energy buildings has emerged as a key part of the global effort for a greener future. Zero-net-energy buildings are buildings that produce as much energy as they consume, resulting in zero net energy consumption. This is achieved through a combination of energy-efficient design, renewable energy production and innovative technologies. One of the most promising advances in this field is the use of living materials, which have the potential to revolutionize the way we build and maintain our buildings.
