Lecture by Prof. Quaschning "Energiewende, Climate Protection and Citizen Energy

In Jerry Yudelson's latest book, "Reinventing Green Building: Why Certification Systems Aren't Working and What We Can Do About It," published in June 2016, the American pioneer of sustainable building writes that certification systems are not advancing the needed sustainable development in the building sector quickly and substantially enough.
This has been shown by the experience of certification systems for sustainable building such as the DGNB, BREEAM and above all LEED seals of approval in recent decades. On the one hand, they are becoming increasingly widespread and their standards and methods are being perfected - on the other hand, they are becoming more and more expensive and complex.

Jerry Yudelson was described by WIRED magazine as the American "Godfather of Green". He is regarded as one of the pioneers of the green building movement in the USA at the end of the 1990s and played a key role in founding the first local chapter of the US Green Building Council in Seattle. The long-time LEED Fellow has trained around 4,000 professionals from the construction industry on the LEED system during his active time. Between 2014 and 2015, he was President of the Green Building Initiative (GBI), a non-profit organisation that provides the Green Globes green building rating system and programme in America.

Yudelsons says the maths is simple: there are 5.5 million buildings in the US, of which about 35,000 are LEED certified today. That's less than 0.7% of the building stock and that's after 15 years of a lot of hard work. It is relatively simple and very clear that we will never achieve the CO2 reduction targets this way. In addition, we have no documentation and no studies, NOTHING! The big challenge ahead of us is the existing buildings and the property market. He goes on to say in his book that it is a misconception that certifications can save the planet.

Yudelson also offers a solution in the book. A data-driven strategy that utilises the latest cloud-based technologies to reduce certification costs by 90% or more. This could achieve a market uptake to 50% of all buildings by 2025.
