Using buildings as a treasure trove of raw materials – or how to save resources...

One third of all global resources go into the construction of buildings. But if something involves lots of resources, it also represents an opportunity to save lots of resources. This is where four criteria under the overhauled DGNB System come in: deconstruction and disassembly, potable water demand and waste...

LCA – or why sustainability needs to take the entire lifetime of a building into...

How big is the carbon footprint of a building? How much grey energy is hidden in its four walls? If you want meaningful and honest answers, you need the right tools.

BIM, sustainability and certification

The building and property sectors have been grappling with the topic of building information modelling (BIM) for several years now.

DGNB & Co. compared – Part 3: Features that make the DGNB System special

For many people, the three leading international systems for certifying sustainable buildings – DGNB, LEED and BREEAM – are sometimes used in the same breath and the public perception is that they’re largely interchangeable.

LCC – or, how do I ask the right questions about costs?

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:...

Biodiversity – or why building owners can do more for biological variety than they...

Exactly what was needed – or why Version 2018 of the DGNB System is much more than...

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...

GEG 2050: DGNB proposal meets with approval and sparks widespread discussion

50Hertz: “A precious award when it comes to design and Baukultur”

Hardly anything makes such a difference to a city’s skyline as the architecture of its buildings. They are more than just a means to an end, more than just four walls that create space for all the things we need to get done. Buildings foster communication; their design can...

Beyond organic: sustainability in the supermarket

When we’re shopping and we think about sustainability, our thoughts quickly turn to the many shades of organic, green and vegan. But the supermarket itself – or rather the building, how it was built and the technical equipment – can also be an impressive testimony to the powers of...

BIM, sustainability and certification

Climate change – can we rise to the challenge?

Two degrees doesn’t sound like a lot. Two is a fairly small number, after all. But how will a rise of two degrees Celsius in global temperatures change our lives and the world? In this case, less is actually more, as Dr Anna Braune, Head of Research & Trends...

Setting a course for the city of tomorrow

The question of how we can equip our cities to meet the challenges of the future is close to all our hearts. These challenges are significant, and they can only be solved through a multilateral mind-set – a place precisely at the overlap between disciplines, through active collaboration and...
