2 DGNB: The German Sustainable Building Council The association for sustainable building in Germany Non-profit and non-governmental organization Independent community of experts More than 500 volunteers in DGNB Working Groups and Committees National and international platform for sustainability in the built environment 2 DGNB 2012

3 A Global Presence for Sustainability 3 DGNB 2012

4 Selected DGNB Members 4 DGNB 2012

5 The Construction Industry Matters 17 % fresh water use 25 % timber use 33 % CO 2 emissions 30 to 40 % energy use 40 to 50 % raw materials 5 DGNB 2012

6 But How Sustainable Is It As Yet? 6 DGNB 2012

7 Do We Need Passive Houses? 7 DGNB 2012

8 Or Rather Active Ones? 8 DGNB 2012

9 How Much Do We Know About Our Buildings? 9 DGNB 2012

16 Criteria for Sustainable Precincts Life cycle assessment Water and soil protection Changing urban microclimate Biodiversity and interlinking habitats Considering possible impacts on the environment Land use Total primary energy demand and renewable primary energy share Energy-efficient development layout Resource-efficient infrastructure, earthworks management Local food production Water circulation systems Life-cycle costs Fiscal effects on the municipality Value stability Efficient land use Social and functional mix Social and commercial infrastructure Objective / subjective safety Public space amenity value Noise protection and sound insulation Open space offer Inclusive Access Development layout and flexible use Urban integration Urban design Use of existing structures Art in public spaces Energy technology Efficient waste management Rain water management Information and telecomunication management Maintenance, upkeep, cleaning Quality of transport systems Quality of motor transport infrastructure Quality of public transport infrastructure Quality of bicycle infrastructure Participation Concept development process Integrated planning Municipal involvement Management Construction site and construction process Marketing Quality assurance and monitoring Quality of pedestrian infrastructure DGNB

17 A Closer Look ENV1.1 ENV1.2 ENV1.3 ENV2.1 ENV2.2 ENV2.3 Life Cycle Impact Assessment Local Environmental Impact Responsible Procurement Life Cycle Assessment - Primary Energy Drinking Water Demand and Wastewater Volume Land Use 17 DGNB 2012

18 A Closer Look ENV1.3 Responsible Procurement Usage of sustainable timber Usage of certified natural stones 18 DGNB 2012

19 Demand for Sustainable Timber At least 50 % of all timber, timber products, and /or timber materials are produced by sustainable forestry. This is verified by an FSC or PEFC certificate and a corresponding CoC certificate Evaluation points 1 Quality level 1 5 Quality level 2 10 Quality level 3 19 DGNB 2012

22 JM14 A Closer Look ECO1.1 Life Cycle Costing Life cycle costing is determined as net present value over a period of 50 years: - Selected construction costs - Selected occupancy costs - Selected operation costs (supply and disposal, cleaning, operation, inspection and maintenance) - Selected repair costs 21 DGNB 2012

26 The Evaluation Matrix 24 DGNB 2012

27 Specifics of the DGNB System Embedded LCA (Life-Cycle Assessment) Systematic analysis of the environmental impact of products during their entire lifecycle. Harmonized by international standards (ISO / 14044) Emphasis on LCC (Life-Cycle Costing) Total cost throughout the entire life-cycle incl. selected construction, operation and maintenance costs directly attributable to owing or using the asset Oriented towards performance and targets Assessment of the building as a whole, not individual measures Dynamic System Adaptable to other technical, societal, cultural and climatic conditions Future-Oriented Based on international standards and guidelines (e.g. CEN/TC 350 etc.) 25 DGNB 2012

28 Is It All Worth It? Costs Certification fees Auditor fees Higher planning costs (?) Higher building costs (?) Benefits Clear target definition Transparent quality control Minimisation of risk and operating costs Maximisation of quality and comfort Visible documentation of CSR 26 DGNB 2012

29 A Sustainability Rating acts as 1. An enhancement of communication for planners and clients 2. An instrument to increase the quality of our built environment 3. A visible demonstration of a company s CSR 27 DGNB 2012
