LEED (Leadership in Energy and Environmental Design) is currently the most well-known international green building certification programme. Numerous buildings in more than 150 countries have already been LEED-certified. The certification is issued by the Green Building Certification Institute, which confirms that buildings have been developed, planned and completed in accordance with measurable sustainability standards.
In Switzerland too, interest in LEED certification is steadily increasing despite various well-known and established building labels.
