The moment a tree is cut down and its biological processes are interrupted, it can be said that the deterioration process of wood also begins. Steps such as the correct cutting of the trunk, drying and storage or the precise specification of the best species for each use will determine its durability. Composed basically of cellulose, hemicellulose and lignin, each wood species has a certain natural durability, also influenced by the environmental conditions of where it is inserted, such as temperature, humidity, oxygen content, and the microorganisms and insects present there. Generally, surface treatments are used to increase the protection of different parts, such as varnishes, oils and other chemical processes. But there are situations in which untreated wood can be used outdoors, achieving a gray and sober aesthetic that blends into the exterior and brings personality to the building.

Kiribati has a population of around 110,000 people and its economy is centered on fishing and agriculture. Comprised of 33 islands in the Central Pacific, its highest point is only 81 meters above sea level, which makes it potentially the first country that could disappear completely due to global warming and the consequent rise in sea levels. The climate crisis has been a hotly debated topic in recent years and terms such as carbon footprint, greenhouse effect, atmospheric aerosols, and many others, are already staples in our vocabulary. Another widely spoken term is “net zero”, or net zero emission, used as a goal for buildings in different industries and countries. Basically, it means that the energy balance is zero.
