7. Harrisdale Village Sustainability Evaluation Objectives The main objectives of this study were • to identify the main environmental impacts of a typical single family dwelling in Western Australia by means of an environmental Life Cycle Assessment (LCA) according to ISO 14040 • to identify the main economic impacts of the similar dwelling by means of a Life Cycle Costing (LCC) analysis • to develop Key Sustainability Performance Indicators including setting benchmarks for the design and use phases of the development

12. LCA ResultsEnvironmental hot spots of construction

13. Summary • Hot spot analysis shows that around 85% of the environmental impactduring the construction phase comes from the slab, walls, roof and windows/glazed doors. • Some of the hot spot impacts only come from a very limited number of products which raises the possibility of product substitution to improve performance. There are also areas where environmental benefits might be obtained by either increasing the contribution of recycling or renewable energy to the system. • Within the use phase the most significant environmental contributor is the electricity used for refrigeration and for cooling. • After the refurbishment costs, the electricity costs are also one of the major contributors to the LCC over the life of the building. • Materials used during refurbishment are of minor relevance to the LCA. • The most significant contribution from refurbishment is the impact on the LCC. While this is at least in part the result of the refurbishment cycle assumptions, it does show that it is possible that a building with high initial costs might perform better overall from a Life Cycle perspective.

15. Why does Germany need a new certification System? Regulations DIN-Standards Guidelines Codes of practice CE Labelling Marks of quality Research projects Architectural competitions Integral Planning Simulations … Certification Of energy efficiency during operation phase High quality in the built environment Although Germany has a leadership in building technology no measure for the holistic quality and no excellence award was existing 17

16. DGNB German Certificate for Sustainable Building 18

17. Rating system: General principles 2/2 System approach and life cycle perspective: Holistic view is the basis of efficient sustainable building. The shift of problems is avoided due to the life cycle approach. Environment product declarations (EPDs) for building products are an important information basis. Individual references and individually determined focal points: The assessment reference reflects the local situation and focal points are individually determined. Basic requirements ensure high quality. 19

18. German EPD system: IBU Structure of the system: The German Institute of Building and Environment (IBU) is an association of material producers open for all producers IBU has established program rules Product forum => develop PCRs Independent advisory board => developed its own SOP (standard operating procedures) Internet based forum => public consultation of PCRs 28.08.2014 20

19. Sustainability rating schemes for buildings Future trends: Fast growing number of certificates in all types of use Life cycle approach (2nd generation) will find the way in other schemes Environmental product declarations (EPDs) according ISO 14025 will supply environmental information on product level International agreements for calculation methods are needed, e.g. common metrics to measure emissions of CO2 equivalents from new homes and buildings European Commissions policies and strategies support sustainability rating schemes 21
