Building certification: the seal of approval for sustainable structures

Building certification systems provide approved methods and procedures to minimise emissions and resource consumption without impacting on building comfort.

At PORR Design & Engineering, we take our responsibilities in the field of sustainability very seriously. We conduct planning in line with approved building guidelines and play a proactive role in improving leading building certification systems. The German Green Building Association (GGBA) has selected us as one of five companies to transfer the American LEED system to the German-speaking world. We also played a decisive role in developing the core system of the ÖGNI (Austrian Society for a Sustainable Property Sector) 2017 for the office, hotel, residential, production and logistics building categories. PORR Design & Engineering has also adapted the globally leading BREEAM certification system for the German, Austrian and Swiss markets.

We provide clients with consultancy with regard to certification for new buildings, modernisation and existing structures on the basis of robust criteria:

  • Sustainability strategies
  • Energy efficiency
  • Renewable and fluctuating energy sources
  • Life cycle costs
  • Demographics
  • Energy monitoring
  • Construction product management and pollutant detection
  • Responsible sourcing
  • Energy and comfort simulations
  • Building operation
