3 Buro Trinius milestones Methodology development environmental assessment of buildings since 1996 PhD in LCA of buildings 1999 (KTH Stockholm, Sweden) Engineering Consultancy Buro Trinius in Hamburg since 2000 International Standardization (ISO), chair of various working groups International R&D projects (SB, LCA, LCC, BIM, ecodesign) Co-Initiator of the Germany Sustainable Building Council (DGNB) Numerous LCC and LCA studies, green building consultancy Appointed EPD verifier (IBU, environdec) Generation of EPDs (ISO & EN 15804) Set-up of standard-compliant quantification tools, (e.g. LCC and cost-optimality tool for activehouse-alliance and VELUX) 3

5 Sustainability is a MUST Sustainable construction is a mega-trend The most significant single industry sector Sustainable Construction a precondition for societal sustainable development Consequently, everybody wants or must be sustainable has basically always been sustainable Whatever somebody does has a positive contribution absolutely or relatively Term sustainable is filled with content - or emptied - to fit the claim

6 ISO: Sustainable Construction Definition of an equal level playing field Sustainable development concept applied to buildings Design, construction, operation, deconstruction Minimized adverse impact Enhancing economic and socio-cultural aspects Providing required functionality and performance Holistic life cycle approach Embedded in decision making Identification of improvement potentials Win-win situations Balanced solutions, not single-criteria priorities economic socio-cultural environmenta l How to count LCC & LCA

7 Green Building Labelling simplified communication Voluntary except e.g. German Federal Buildings BUT: CLIENT OPTION = OBLIGATION for project partners Labelling criteria become part of building specification Requirements concern properties, processes, services, documentation All participants must respond, involve, relate to requirements

8 The sustainable construction trap -- decision making based on incomplete information -- when all required information is available, all decisions have long been taken PROEJCT INTEGRATION AT EARLY STAGES 8

9 Labelling is more than a scheme green building management Identify approach Labeling scheme or client-specific goal and reference definitions Specify target Communicate to decision takers Evaluate design drafts Monitor development Provide improvement potentials Establish as decision-making parameter Ensure communication and documentation 9
