HOCHTIEF—sustainable on a global level

Within Europe, our efforts towards green building extend beyond the German borders—to Poland, for example, or Switzerland. In the USA, our subsidiary Turner Construction is working on establishing sustainable building on a more widespread basis. The company already holds a leading position in the US market in this area. Employees at our CIMIC companies in Australia have also specialized in the area of sustainable construction.

Generally speaking, HOCHTIEF supports all endeavors to introduce and establish certification systems for green buildings. Together with our subsidiaries, we advise and accompany our clients during the certification of sustainable buildings. The best-known systems are:

DGNB certificate

HOCHTIEF is a founding member of the German Sustainable Building Council (DGNB). Since January 2009 this organization has been awarding DGNB certification to projects which are kind to the environment, economically efficient, and user-friendly. The certificate is awarded in the categories of Gold, Silver and Bronze.


In the USA, the Leadership in Energy and Environmental Design (LEED) standard in Silver, Gold or Platinum, awarded by the U.S. Green Building Council is the most respected sustainability award. HOCHTIEF subsidiary Turner Construction is a green building pioneer in the USA. The company has already completed over 200 projects which have received LEED certification (as at June 30, 2011).

Green Star

HOCHTIEF is represented on the Green Building Council of Australia (GBCA) through its CIMIC companies. Since 2003, the GBCA has been awarding the Green Star in Australia. The classification system awards four, five or six stars to buildings which are especially environmentally-friendly and sustainable.


MINERGIE® is the Swiss quality seal for new and modernized sustainable buildings. The quality mark is jointly sponsored by business, the cantons and the Swiss state.


BREEAM (Building Research Establishment Environmental Assessment Method) is an international certification system for sustainable building which was developed in the UK. It uses a simple points system in eight assessment categories (management processes, health and wellbeing, energy, transport, water, materials and waste, land usage and ecology, and pollution), awarding a quality seal in one of four rating bands.


CEEQUAL is a pioneer of the certification of infrastructural projects. The British system for the evaluation and certification of sustainable aspects with regard to civil engineering, infrastructural projects, landscaping and work in public spaces was founded in 2004 and has developed so much in the meantime that the concept was completely revised in 2011. The aim is to promote greater environmental awareness on infrastructural projects so that ecological and social aspects are given even greater consideration during design, planning and construction.


The Greenroads assessment system is an independent, point-based system from the USA, used to certify sustainable road and transportation infrastructure projects. It renders the impact of individual planning and construction measures quantifiable. The Greenroads Foundation was established in 2010.


In Australia, sustainable infrastructural projects are recognized by the Infrastructure Sustainability Council of Australia (ISCA). This authority’s mission is to enhance the livability and productivity of cities and communities through sustainably planned, acquired, built and operated infrastructure. The IS quality seal is the only blanket rating system for assessing the sustainability of infrastructure across planning, construction and operation. It is awarded in the categories of “Design”, “As Built” and “Operation”.
