Green building and wood

Green building is when buildings are built to be as environmentally friendly as possible. That means using materials like wood that come from renewable sources, and using sustainable practices, like using less water and energy. Wood is one of the best materials to use in green buildings because it comes from a renewable source. Trees can be planted and replanted so that more wood is available to be used in green building. Furthermore, wood is naturally energy efficient, meaning that it helps keep the interior of the building warm or cool, which helps to reduce energy costs. To make sure that the trees used for building materials are sourced sustainably, they must come from forests that are managed responsibly.
