Blue building

The term blue building is a further development of the term “ green building ”, which describes buildings as sustainable. In contrast to green building, it is about the development away from pure energy efficiency towards overall sustainability over the entire life cycle of a building. Economy and ecology play a major role, as do technical and socio-cultural performanceAspects, the careful use of resources and energy, the consideration of economic and human needs. At Blue Buildings, the focus is on the users of a building; they should be able to feel comfortable in the building.

Uniform standards

Since the topic of sustainability in construction has become more topical, different standards have been established in the various countries. But there are efforts to standardize them. Environmental Product Declarations (EPDs) are an important measure towards comparable values : They are intended to provide information about the materials used in building products and include all relevant building material groups. This is how you can calculate an ecological balance.

Certification systems

DGNB

Many countries have developed their own standards for the certification of energy-efficient buildings, i.e. green buildings . The certification as a Blue Building has so far been carried out with the DGNB certificate. The DGNB certificate guarantees that in addition to ecological and economic aspects, socio-cultural aspects are also included in the assessment in the same way. According to the DGNB, it is fulfilling its claim as a second generation system. That is why DGNB uses the color blue and the slogan “more than green”. The DGNB system was first adapted in 2009 by the Austrian Sustainable Building Council ( ÖGNI ); The Swiss Society for Sustainable Real Estate Management (SGNI) has been using the DGNB certificate since 2010 . The system was most recently adapted by the Bulgarian Green Building Council (BGBC).

BlueCARD

With the BlueCARD, ÖGNI has developed a system, comparable to an assessment sticker on vehicles, with which the inventory can be checked periodically. The BlueCARD is the first rating system available on the market in Austria that covers the minimum standard for sustainable buildings, the “Austrian Standard”, jointly supported by ÖGNI, klima: aktiv Bauen und Sanieren and ÖGNB.

Certified buildings

Certifications of buildings are carried out in different categories. In Austria, for example, there are DGNB-certified commercial buildings such as the Billa branch in Perchtoldsdorf, Klimaschutz-SPAR Murau, and MGC Vienna. Certified office buildings are for example 2nd Central Vienna, Marximum Vienna, Etechcenter Linz, Millennium Tower Vienna and Nikolaiplatz Graz. Other categories are residential buildings, educational buildings and laboratory buildings. Lighthouse projects of sustainability can be found in the ÖGNI project gallery.
