10 What is driving demand? Codes and Standards Organizational Initiatives

11 Construction Industry Demand Codes and Standards LEED v.4 - MR product and building level LCA credits Living Building Challenge - Calculation of carbon emission impacts ISO Normative reference to ISO and International Green Construction Code

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

13 Integrating LCA and EPDs UBC Biological Sciences Center UBC District Energy Center Moving towards EPDs Professional development

14 Biological Sciences Centre to quantify and market the value of the UBC Renew program. Achieved LEED Innovation and Design Credit. Development of LCA databases for benchmarking future project decisions. Improving the efficiency of the methods and accuracy of LCA results in future design scenario modeling efforts.

15 Biological Sciences Centre Extraction and Manufacturing of New Products Scenario 1 Renovating Partial Demolition Salvaged Partial Construction Salvaged Renovated Existing Extraction and Manufacturing of New Products Scenario 2 Building New Full Demolition Full Construction Newly Built

16 Biological Sciences Centre Challenge of reference design Simplified design comparison same footprint the floor to floor height increase by 4m same operating energy performance

17 Biological Sciences Centre

18 District Energy Centre To manage environmental and economic costs with integrated LCA-LCC. Communicate the environmental performance of the final building design. Earn a LEED ID credit for using whole building LCA.

19 District Energy Centre Object of Assessment

20 District Energy Centre Element Unit Rates per m2 Element Design Scenarios B11 Economic Unit Rate (CAD$) Fossil Fuel Consumption (MJ) Global Warming (kg CO2eq) Acidification (moles of H+eq) Human Health Criteria Respiratory Eutrophicatio (kg PM10eq) n (kg Neq) Ozone Layer Depletion (kg CFC- 11eq) Smog (kg O3eq) 99mm and 239mm CLT, and 200mm cast-in-place Hybrid Design concrete walls $ XXX Steel Design 200mm CMU walls $ XXX

21 District Energy Centre Building design - geometry and materials with integrated LCA-LCC results. Material Comparison Hybrid vs. Steel Designs

22 Direct Costs (NPV $) District Energy Centre Element design - geometry and materials with integrated LCA-LCC results. District Energy Center Stage 1 high low Global Warming Potential (kg CO2 eq)

23 District Energy Centre 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

24 Moving towards EPDs Shortage in supply and usability Need alignment Impact Categories Process Modules

25 Moving towards EPDs Recognized product standards. Environmental Product Declaration (EPD) Programs

26 Moving towards EPDs EPD Publications Softwood Lumber Softwood Plywood Oriented Strand board Glue Laminated Timbers Laminated Veneer Lumber Wood I-Joists Redwood Decking

27 Moving towards EPDs Concrete EPDs

28 Moving towards EPDs Functional Unit: performance related reference to which input and output data are normalized per whole building per m 2 floor area Reference Flow: outputs from system required to fulfill the function expressed by the functional unit. Building Intermediate Flow: output from a process that is input to other process that requires further transformation within system. Construction Products

39 Organizational Support Natural Resources Canada As of April 1, 2012, pursuant to departmental strategic frameworks, new construction and build-to-lease projects, and major renovation projects, will achieve an industry-recognized level of high environmental performance. In addition, existing crown buildings over 1000 m2 will be assessed for environmental performance using an industry recognized system. NRCan has developed an initiative titled, Low Carbon NRCan, to contribute to the departmental commitment of meeting the specific goals outlined in the Federal Sustainable Development Strategy (FSDS). Proposed strategy is to Assess these types of projects using Athena s Life Cycle Assessment tool (i.e. embodied effects) Require energy simulation results (i.e. operating effects) Commit to meeting Green Globes Design 3 Globes for new buildings.

40 Organizational Support Olympic Games Impact (OGI) Study developed by the International Olympic Committee (IOC) analysis of the impact for each edition of the Olympic Games to help bidding and future Olympic organizers identify potential legacies in order to maximize the benefits of hosting the Games. 126 indicators are used in the OGI study to measure impact across economic, environmental and social areas.

41 En27: Life-cycle Inventory of Olympic and Paralympic Venues to provide an overall, synthetic view of the inputs (energy and raw materials) used for the life-cycle of an Olympic or Paralympic venue and the outputs (water effluents, airborne emissions, solid waste, etc) that are released into the environment.
