  1. ImpactEstimator Highways and Buildings RobSianchuk, MASc Director de Desarrollo de Negocios ColdstreamConsulting Ltd. rob.sianchuk@coldstreamconsulting.com November 8, 2013

  2. Presentation Outline • Life cycle approaches • Driving demand • Designing with LCA and LCC • Professional Development

  3. 1. What is a life cycle approach?

  4. Both are Life Cycle Approaches – Different Metrics, Different Methods –life cycle assessment life cycle costing

  5. UNEP/SETAC Sustainability Framework Environmental Security Financial Security Financial Management Decisions Environmental Management Decisions Environmental Product Declarations (EPDs) Financial Statements LCA Modeling Financial Modeling

  6. Inventory Analysis Impact Assessment Air Resources Water kg CO2 eq Energy ? Land Investment Costs NPV CAD$

  7. Inventory Analysis Impact Assessment Air Resources Water kg CO2 eq Energy kg CFC-11 eq Land kg SO2 eq Investment Costs NPV CAD$ kg N eq kg PM10 eq kg O3 eq

  8. What is driving demand? • Codes and Standards • Organizational Initiatives • Infrastructure Deficit

  9. Construction Industry Demand: Codes and Standards • LEED v.4 • Green Globes • International Green Construction Code • ISO 21931-1 • Living Building Challenge

  10. Construction Industry Demand: Organizational Initiatives • Olympic Games Impact (OGI) Studies • En 27: Life-cycle Inventory of Olympic • and Paralympic Venues • Natural Resources Canada • Federal Sustainable Development • Strategy includes assessment of • embodied carbon • University of British Columbia • inclusion of LCA in request for • information from architects and • consulting teams

  11. Construction Industry Demand: Infrastructure Deficit • North America has a significant infrastructure deficit • Mostly built between 1950’s and the 1970’s • Living in a resource constrained world • Slower growing economy • Aging population – smaller tax base • Larger population drawing on fewer • natural resources • Implications • Need to do more with less • Focus on life cycle performance

  12. Designing with LCA and LCC • District Energy Center • Moving towards EPDs • Impact Estimator for Highways

  13. Designing with LCA and LCC • District Energy Center • To manage environmental and economic costs with integrated LCA-LCC. • Earn LEED Innovation & Design credits

  14. Reference Design! Elemental Cost Analysis Financial Modeling format used by Canadian Quantity Surveyors to do Life Cycle Costing (LCC). Life Cycle Assessment tool use.

  15. Building design - geometry and materials with integrated LCA-LCC results.

  16. Elemental design

  17. Elemental design - geometry and materials with integrated LCA-LCC results. high Direct Costs (NPV $) low Global Warming Potential (kg CO2 eq)

  18. Learning Outcomes • Design Team Engagement • Kick off Integrated Design Process • Clarify design goals • Set expectations and information needs • Develop standards and benchmarks for reference designs • What is a fair comparison?

  19. Designing with LCA and LCC • District Energy Center • Moving towards EPDs

  20. Designing with LCA and LCC • District Energy Center • Moving towards EPDs • Supply • Alignment • Impact Categories • Process Information Modules • Usability

  21. Recognized product standards. Environmental Product Declaration (EPD) Programs

  22. Concrete EPDs

  23. Functional Unit: • performance related reference to which input and output data are normalized • Reference Flow: outputs from system required to fulfill the function expressed by the functional unit. • Intermediate Flow: • output from a process that is input to other process that requires further transformation within system. • Express LCA and LCC results • per whole building • per m2 floor area • (or per m2 building element) Building (or Building Element) Construction Products

  24. Modular information structure EN 15978 and 15804 Building System Boundary

  25. EPD Publication Experience • Softwood Lumber • Softwood Plywood • Oriented Strand board • Glue Laminated Timbers • Laminated Veneer Lumber • Wood I-Joists • Redwood Decking • Useability of pdfs?

  26. Designing with LCA and LCC • District Energy Center • Moving towards EPDs • Impact Estimator for Highways

  27. Designing with LCA and LCC • District Energy Center • Moving towards EPDs • Impact Estimator for Highways • Background • Supporting Data • Modeling Capabilities

  28. Impact Estimator for Highways • Developed by the Athena Sustainable Materials Institute. • Funded by Cement Association of Canada and Environment Canada with technical engineering expertise from Morrison Hershfield. • Can be used to create LCA model of any type of roadway cross-sectional design.

  29. Impact Estimator for Highways • 100+ roadway materials in the database. • Base, Sub-base and surface materials (flexible & rigid) • Rigid – General use (GU) and blended cements (PLC) • Flexible – Hot mix asphalt (HMA) and Warm mix asphalt (WMA) • User can create and save customized product • mixes • supply transportation modes and distances

  30. Impact Estimator for Highways • 30+ large construction equipment profiles in the database • customizable to reflect regional/seasonal working conditions and usage rates.

  31. Roadway Design

  32. Rehabilitation Schedule

  33. Pavement Vehicle Interaction (PVI)

  34. Pavement Vehicle Interaction (PVI) http://web.mit.edu/cshub/news/pdf/PVI_Report-2012.pdf

  35. It’s free! http://www.athenasmi.org

  36. Comes with Sample Projects.

  37. See results for Impact Assessment, and Inventory Analysis.

  38. Create different roadway design scenarios and compare.

  39. Professional development • Civil engineering course at University of British Columbia • Association of Professional Engineers and Geoscientists of British Columbia

  40. 2011/2012 • CIVL 498C Whole Building Life Cycle Assessment • 4thyear Civil Eng technical elective • Established in January 2009* • Attended by undergraduate and graduate architecture and engineering students from civil, mechanical, materials, environmental, chemical and mining specializations 2010/2011 2009/2010 2008/2009 2012/2013
