Env isi on rating system level 1 checklist and guidance documents
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


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)


Env isi on rating system level 3 operational focus with flexible weighting
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


Env isi on level 4 future software for alternative solutions costing
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
