  1. “We’re Building 2050 Today”* How infrastructure will perform for the next several generations depends on what we build today Urgent Issue! Wackernagle graphic

  2. Ecological Overshoot (Global) Natural Capital Eco-system services 30% overshoot Energy, water, materials Impacts Produced Capital

  3. Achieving Sustainable Performance: Three Dimensions of Response Y. Range of sustainable performance Restorative Sustainable Decommission / Recycle / Disposal Operation & Maintenance Construction Reuse / Reconfigure Improvement Design Conventional Planning Project team Areas of control Owner Affected stakeholders X. Project Life Cycle Partner organizations Regulatory institutions Areas of impact 10.3 Z. Stakeholder Collaboration

  4. envision Rating SystemLevel 1: Checklist and Guidance Documents Benefits of Level 1 of the Rating Tool Promotes understanding of sustainability and triple bottom line accounting Provides rule-of-thumb applications and generic measures for sustainable infrastructure projects After training, allows practitioners and owners to self-assess projects based on rating system concepts (leads to “informal” sustainability score) Gives access to references, project library, key resources and contacts

  5. envision rating system Level 2: Formal Project Assessment, including Composite Score with Pre-Weights Benefits of Level 2 of the Rating System Ability to assess and rate overall project contribution to sustainability, with third party quality assurance and verification available Provides recognition of achievement through awards for high-scoring projects Uses standard matrix of criteria and sums to an overall composite score (similar to USGBC’s LEED)

  6. envisionrating system Level 3: Operational Focus with Flexible Weighting Benefits of Level 3 of the Rating System Recognition of dimension-specific achievements based on operational priorities Instead of pre-weighted scoring, discretion is provided to weight scores according to operational imperatives of the owner and project Scores in other dimensions (other than operational focus) still must meet baseline measures Third-party verification available for award recognition Promotes continuous incremental improvement toward sustainable solutions

  7. envision Level 4 (future): Software for Alternative Solutions & Costing Benefits of Level 4 of the Rating System - Provide decision support tool for engineers and other practitioners in design of sustainable projects Enhanced web–based software Links to industry-recognized decision support software Links to industry data with Parametric costing Allow project systems sustainability review and trade-offs among competing goals Expanded project and technology library
