LEED certification in gold
The US LEED (Leadership in Energy and Environmental Design) certificate is awarded worldwide. Thus, LEED certified buildings, unlike some other building rating systems, can be compared across borders. The focal points of building certifications are the most important comfort parameters such as sound insulation, brightness and tanning, summer suitability and indoor air quality. Furthermore, technical criteria such as accessibility, fire protection, glare and sun protection are evaluated, as well as life cycle assessment, life cycle costs and construction ecology, energy and water efficiency. Due to the international LEED certification behind HoHo Wien, the processed wood must be certified for sustainability. The companies MM-Holz and Hasslacher Norica Timber, which are involved in HoHo Vienna, can obtain PEFC certification. This certification for sustainable forest management and processing is audited by rigorous audits by independent certification bodies; It guarantees that wood and paper products come from sustainably managed forests.
