• The materials used shall be in compliance with the specific VOC emission limits of interior paints and coatings.
• At least 90% of the workstations shall have individually controlled lighting systems.
• At least 75% of the workstations and of other regularly used areas shall have good sunlight.
• The above technical aspects are summarized and analysed, and relevant modifications are applied as necessary on the basis of the results obtained. This is all supported by a LEED certification.

An environmentally conscious building certification system that can make the office building more valuable.

BREEAM (BRE Environmental Assessment Method) is the firstly developedcertification system for environmentally conscious buildings. The BRE (Building Research Establishment) is an independent organization in the United Kingdom dedicated to improving the quality of the constructed environment. As of 01 January 2010, the commercial, office and industrial buildings can be certified internationally using the BREEAM Europe Commercial 2009 certification system. In addition, there is a possibility to certify only the structure of a building. BREEAM supports energy-efficient buildings, various water-reduction solutions, as well as investments that do not require new green spaces, but are implemented as brownfield projects and thus have less impact on the environment.

The BREEAM certification for new buildings consists of two main parts: a certification during the design phase and a certification after the completion of construction. The final certification can be obtained after the certification following the completion of the construction, as this is when it can be ensured that the statements or plans made during the design phase have actually been implemented. The BREEAM-certified buildings are classified in one of the following classes: pass, good, very good, excellent, outstanding. As in the case of LEED, the higher the rating of a company building, the more valuable it is. In 2010, the BREEAM In Use system was launched to certify existing buildings.
