BREEAM is established in 1990 the British building assessment system. It was and is used to certify newly established buildings and urban planning assumptions as well as guidelines for existing buildings and urban developments.
Depending on the type and function of the set real estate: the plot of land or building is assessed on a scale point in 10 categories.
Earned points are converted into percentages, which in turn are multiplied by the weight assigned to each category and depending on the type of the evaluated building.
Won points in each category are then added together resulting in a score of 6-point scale:
- < 30% - non-certified,
- 30-44% - satisfactory,
- 45-54% - good,
- 55-69% - very good,
- 70-84% - excellent,
- 85% - outstanding.
Most points it is possible to win in the categories of energy (21) and the least in the category of water (6).
The great advantage of the system is that it is used worldwide because of the flexible adapted to the climatic conditions and the law regulations of each country.
