It wasn’t until the extent of insect extinction was understood by the general public that people began to realise how important biodiversity has now become to all of us. Starting with the good news for anyone involved in a construction project: buildings have a significant contribution to make to the promotion of biodiversity. This is aptly demonstrated by the Biodiversity criteria introduced by the DGNB for its 2018 rework of the criteria set.
Whether people like it or not, sustainable buildings still have to be judged by how economical they are. For us, this means the DGNB System is not just built on two pillars – environmental quality, next to sociocultural and functional quality; there’s a third key pillar about financial viability: economic quality. One important factor when it comes to economic quality is the criterion Life Cycle Costing (LCC).
Certified construction? Oh yes – that’s those handy plaques in platinum or gold, the ones that allow building owners to walk around with architects and announce publicly, “Look everyone, we’re sustainable!” Sort of – yes, that’s one way to describe sustainability certificates. Though actually, buildings don’t simply earn certificates because they deserve to, especially after investing so much time and hard work. It is also a well-earned award for of all those important decisions to look after the environment, for keeping a close eye on commercial viability, and for ensuring the development will be good for the people within the buildings and districts.
Thinking consciously about how natural resources are used has always been a core topic at the DGNB. Right from the beginning, the DGNB has offered a certification system that favours a holistic approach to carbon footprints. Therefore, this has always involved not only the conscious selection of building materials according to their composition and origin, but also a methodical assessment of the ‘reclaimability’ of individual residual materials – all based on strict criteria, criteria that have thus become established in the market.
