Green buildings refer to structures that are designed, constructed, and operated with the goal of reducing their environmental impact. This includes using sustainable building materials, optimizing design and systems to minimize energy and resource consumption, and promoting a healthy and eco-friendly living environment. Despite the increasing global interest and growth in green buildings, there is still a lack of expertise in this field. To design truly sustainable buildings, steps such as sourcing materials locally and minimizing energy use must be considered. Green building research has been a focus in South Africa, with a scoping review and future roadmaps being developed in 2024. One such material that has gained attention is an energy-saving building material that is cost-effective, environmentally-friendly, and quick to cure. To further promote sustainable building development, research in this area should be closely examined.
