Concerns about the exploitation of forests in the world sometimes encourages consumers to choose non-renewable materials, whose production is more polluting and damaging to the environment than wood. When forests are sustainably managed, wood is a material having a lower environmental footprint.
Few environmental building rating systems have a basic life cycle analysis of materials. Analysis of the life cycle takes into account the environmental impact of the choice of construction materials. Fortunately, this situation is changing and more organizations analyze the possibility of introducing into their evaluation systems. The design of sustainable buildings is related to methods of sustainable forest management.
The guiding principles of green building
* Reducing energy consumption throughout the building’s life;
* Minimize external pollution and environmental impact;
* Reduce embodied energy and resource depletion;
* Minimize pollution and harmful health effects.
There are several ways to define the environmental performance of buildings. When the green building rating systems incorporate the concept of the life cycle, they are an improvement over traditional scoring methods offered by most programs.
In many European countries, legislation aimed at reducing emissions of greenhouse gases by greater use of wood, or consideration of wood as a preferred building material. Recently, the Government of Québec began the same curve with its use of wood in construction Strategy in Quebec.
One of the changes to national building regulations is to encourage construction of wooden multi-level buildings as the all-wood nine-story building under construction in England.
