Content Introduction to our project Methodological basis LCA database for Ecodesign LCA modeling and tools for Ecodesign College of Architecture and Environment, Sichuan University College of Architecture and Environment, Sichuan University
Introduction to our project � Title: Ecodesign technologies for chemicals and building materials � Aim: to develop methodologies and tools for ecodesign, and apply them to selected chemicals and building materials � 2007-2010, with six partners China National Institute of Standardization Environmental Certification ITKE Environmental Center of SEPA, China Technology Co. College of Architecture and Environment, Sichuan University College of Architecture and Environment, Sichuan University
Methodological basis � LCA-based Ecodesign Measured generic scenario LCA, based Inputs & = + + database analysis on production Outputs Company i Production Material Product Use End of Phase Preparation Manufacture stage life Design Design Ecodesign = Phase design + LCA Material choice Process choice Usage & disposal Estimated generic scenario LCA, based = + + Inputs & database analysis on design outputs College of Architecture and Environment, Sichuan University College of Architecture and Environment, Sichuan University
Scope & Framework Ecodesign methodology Topics Integrated solution (LCA-based) � Ecodesign � methodologies � guidelines � indicators and criteria � LCA � data and info. � product data � EPD (Type � implementation III) Ecodesign software LCA, based LCA, based Ecodesign practice on design on production � key chemicals & building materials generic data EPD （ ISO14025 ） LCA platform � LCA software � certification program � generic database � EPD software product data � product database � products certification College of Architecture and Environment, Sichuan University College of Architecture and Environment, Sichuan University

LCA database � a limited goal in this project, but the first step in this long-term task � Example: Hydropower in China (2006) � Installed capacity: 25984MW, ~20% of grid mix Total installed Sample Sample capacity Hydropower capacity (MW) and number (MW) and in China proportion in 2006 proportion Large scale 185550 (71.41%) 71 132240(71.27%) >250MW Medium scale 31990 (12.31%) 113 14074(40%) 50 ～ 250MW Small scale 42300 (16.28%) 146 4728 (11.18%) <50MW College of Architecture and Environment, Sichuan University College of Architecture and Environment, Sichuan University
� Life cycle of hydropower Material Power station Hydropower Dismantlement preparation construction production � Direct inputs and outputs (per 1kwh) Cement (t) Steel (t) Transp. by Transp. by road (t.km) train (t.km) Large scale 1.08E-06 5.21E-07 2.20E-03 5.20E-04 >250MW Medium scale 2.31E-06 1.26E-06 5.50E-03 1.26E-03 50 ～ 250MW Small scale 2.99E-06 9.79E-07 8.60E-03 9.79E-04 <50MW � Still problems: e.g. GHG emissions from reservior College of Architecture and Environment, Sichuan University College of Architecture and Environment, Sichuan University
LCA tools based on matrix model College of Architecture and Environment, Sichuan University College of Architecture and Environment, Sichuan University
LCA tool for Ecodesign LCA tool by Sichuan University (old version) constructing flow chart inputting inventory data College of Architecture and Environment, Sichuan University College of Architecture and Environment, Sichuan University
LCA tool for Ecodesign � LCI and LCIA � It’s suitable for modeling the existing production, � New features are expected for modeling the design of new products. College of Architecture and Environment, Sichuan University College of Architecture and Environment, Sichuan University
Information flows in Ecodesign LCA side Design side � User’s demand LCI � flow chart � Feature design � material and � Structure energy flows, design � Processing emissions design LCIA Indicators Guidelines College of Architecture and Environment, Sichuan University College of Architecture and Environment, Sichuan University
Product data model for Ecodesign � Product structure: Tree-like BOM (bill of materials) � Materials (weight) � For LCI � Contents � For RoHS, WEEE, etc. � Connection � For disassembling � For example: � Recycling ratio requirement for electronics Pre Eco-it College of Architecture and Environment, Sichuan University College of Architecture and Environment, Sichuan University
Processing model for Ecodesign � Modeling of processing: cutting processing as example � Inputs and outputs Roughcast Parts Cutting Fluid Aging cutting fluid Cleaning Fluid Aging cleaning fluid Cutting Tool consumption Waste processin Energy Metal Dust g Lubricants Harmful gases Machine Noise Waste Machine � Parameter-based model, e.g. Material use = Roughcase (weight, from design) � Energy use = machine power * time � Waste = Roughcase – parts (weight) …… � College of Architecture and Environment, Sichuan University College of Architecture and Environment, Sichuan University
Guidelines and indicators for Ecodesign � along life cycle stages � based on product data (design) Manufacture stage Use stage design End-of-life design Compliance design Guidelines � long life-time � � design DfDisassembl WEEE & RoHS � materials choice � balanced life-time � � DfRecycling Package � process choice � easy maintenance � � DfReuse REACH � … � � … … Indicator � Single index: Material imputs, Energy use, CO2 emission, recycle ratio etc. � Aggregated index: LCIA-based index, localization of index Product Data : structure, material, weight, ingredient, link, disassembling etc. College of Architecture and Environment, Sichuan University College of Architecture and Environment, Sichuan University
Type III environmental declaration procedure PCR work group no PCR PCR PCR PCR Application Application exist? exist? making making yes Company PCRs indicate the Declaration Declaration Company and consultant draft draft directions of improvement for ecodesign. Declaration Declaration Declaration Declaration verification verification publication publication Verifier Operator College of Architecture and Environment, Sichuan University College of Architecture and Environment, Sichuan University
Summary � Ecodesign in ongoing project is � based on LCA method, � combined with Type III environmental declaration. � It calls for an integrated LCA modeling method and tools, which should � link to LCA database to provide background data support, � facilitate transformation from product design to LCI / LCIA and to indicators, � link to PCRs for directions of improvement.
