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

Summary
Hot spot analysis shows that around 85% of the environmental impact during 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.

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 …
High quality in the built environmentCertification
Of energy efficiency during operation phase
Although Germany has a leadership in building technology no measure for the holistic quality and no excellence award was existing

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.

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

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
