PRESCO Objectives of PRESCO 1/3 European “Code of Practice” for Sustainable Construction  Internal Compilation and Integration Phase  Filters: PRESCO Meetings Local and/or Regional Networks 1 st European PRESCO-CRISP Workshop, June nd PRESCO Expert Workshop, October 2003  Final Code with 200 to 250 practical recommendations Allowing for regional differences Covering not only environmental, but also social and economical aspects (sustainability)

PRESCO Objectives of PRESCO 2/3 Environmental Assessment and Design Tools  Exchange of information  Transfer of knowledge and data  Inter-Comparison and Benchmarking of LCA- based environmental assessment and design tools on reference buildings  Evaluation of Code of Practice  Towards a harmonised approach for environmental performance assessments

PRESCO Objectives of PRESCO 3/3 Information and Communication Channels for all decision-making stakeholders  Meetings, Visits, Workshops and 1 International Conference (2004)  6-monthly Newsletter  Code of Practice (2003)  Website:

PRESCO Actions  Action 2.1. Selection of existing or virtual reference buildings  Action 2.2. Environmental performance assessment of reference buildings  Action 2.3. Comparison of results and study of the influence of the use of the Code of Practice  Action 2.4. Definition of a common baseline for assessment methodologies

PRESCO Reference buildings  1st phase: Start with ‘easy’ exercise: simple volume – one material  CUBE  2 nd phase: complete building: FUTURA House  3 versions of same building  3 rd phase: virtual redesign of FUTURA House  apply recommendations

PRESCO Assessment of CUBE  Fixed parameters: dimensions, material (reinforced concrete), energy demand, …  Assessment: very divergent results!  Different assumptions (volume, electricity type, percentage of steel, …)  Various sources of basic LCI data  Other sets of result indicators

PRESCO FUTURA House  Basis for calculations: Futura House – EMPA demonstration project  3 structural types considered: wood, brick, concrete  Basic data available through EMPA, details set by WP2 partners
