Certified building


BREEAM (Building Research Establishment Environmental Assessment Method) is an environmental standard for the construction industry in Europe, owned by BRE Global Ltd. It was developed in the UK and the ecolabel was first launched in 1990, making it the world’s oldest environmental building standard. The BREEAM assessment evaluates the procurement, design, construction and operation of the building.

Buying Guarantees of Origin with this standard guarantees that the renewable energy adheres to the standard’s requirements.

Focus areas

BREEAM measures sustainable value in a series of categories, ranging from energy to ecology. Points are scored within each category and the final total determines the rating.

BREEAM certified buildings guarantee:

  • 100% renewable energy sources. The energy consumed comes from accredited renewable energy sources
  • Renewable energy sources include solar power, wind power, bioenergy and hydropower. If the building uses energy from hydropower it comes from a small-scale production, with less than 20 MW installed capacity
  • Three years purchasing contract

The general BREEAM expectations are the same in all BREEAM countries, but many countries have developed national BREEAM manuals. In countries without national manuals, BREEAM Europe Commercial or BREEAM International Bespoke is applied.


Meet an environmental standard of your choice

Consume renewable energy meeting requirements of specific standards or ecolabels. Buy Guarantees of Origin from power plants that meet stricter environmental standards and are verified by an external auditor. Choose between national or international ecolabels and standards, document the age and type of the power plant, technology and unique operational focus, and raise funds for renewable energy projects.
