2 Global chalenges - Why we need new tools?

3 Global warming & sea level rise: Which countries are most in danger? 44 % of the world's population live within 150 kilometers of the coast. Source: UN Atlas of the Oceans, (

4 2015 Paris climate conference Result: Limiting global warming to less than 2 degrees, ideally 1.5 degrees Implementation: Global greenhouse gas emissions must be reduced to 0 between 2045 and 2060 and previously emitted CO2 must then be removed from the earth's atmosphere. The goal can only be met by immediately embarking upon a stringent climate policy, as the window of opportunity is rapidly closing. Image: Lizenz: CreativeCommons 2.0

5 What contribution buildings can have to achieving the UN climate protection goals? Global greenhouse gas emissions by Economic Sector, 2010 Agriculture, Forestry, and Other Land Use 24% Other Energy 10% Industry 21% Electricity and Heat Production 25% Buildings 6% Transportation 14%

6 Energetic renovation of buildings in Germany What annually renovation rate would we have to achieve to achieve climate protection goals in 2050? And what was the renovation rate in Germany in 2016? >2% <1% Source:

7 Why is the energy renovation rate of the buildings so low? Barriers on the side of owner Information deficits and risk aversion Financial restrictions Lack of motivation Energetic renovation vs. identity Barriers on the planning/ building site Lack of (qualification of) construction workers and planners Lack of relevant qualified professionals The fee structure for architects/ engineers Insufficient controls (barriers in the Legislation) Bilder: Gemeinfrei Stahlhof Düsseldorf, 1904 erbaut und heute darin untergebracht ist derzeit das Verwaltungsgericht Düsseldorf

8 UN Sustainable Development Goals

9 Complex challanges require holistic tools

10 The DGNB system as a planning and management tool for sustainable cities

11 The holistic DGNB approach Typical Green-Building-Ratingsystems Design for Certification Design for Sustainability Analyze (CO2) emissions holistically and reduce them over the entire lice cycle

12 What makes the DGNB System unique? Developed by members for members Life cycle incorporated in all calculations Equal consideration for Ecological, economic, sociocultural and aspects Overall-performance oriented, rather than focus on individual measures

14 DGNB System A holistic Approach

15 The DGNB evaluates holistically and performance oriented

16 DGNB Certification Systems Applicable for every use and type as well as in every phase Buildings in use New construction Existing buildings Districts Interiors Renovation Design quality

17 Buildings in use Evaluation Criteria at a Glance 9. Mobility offers 8. Security and responsibilites of the operator 3. Resource efficiency 1. Strategy and communication 4. Procurement 2. Facility Management 6. Satisfaction of users DGNB Certificate performing builings 5. Maintaince of value and operational costs 7. Sociocultural offers

18 DGNB software support for buildings in use + Current status at a glance + Intuitive operation via infographic

19 Buildings in use suitable for portfolios Certificate Documentation for each project (according to requirements) Basis Certification One documentation for all projects Project 1 Project 2 Project 3 Project 4 Project 5 Project 6

20 DGNB software for international portfolio certification
