    • • Non-Building Construction in the U.S.• The need for Sustainability• Current ASCE Efforts in Sustainability• Institute for Sustainable Infrastructure and the envision Rating System• International Green Construction Code
    • • McGraw-Hill construction starts as of February 2011 (annual adjusted rates): – Total Construction: $404.87 Billion • Commercial Building: $132.2 Billion (32.7%) • Residential Building: $121.0 Billion (29.9%) • Nonbuilding Construction: $151.5 Billion (37.4%)
    • Subject Grade Comments Aviation 3rd in the nation with 124 paved and lighted general aviation airports. Only 58% of runways, 57% C- of taxiways and 62% of aprons meet the satisfactory condition index Bridges Second largest inventory of bridges in the United States. $3.6 billion to replace all thehttp://ohioasce.org/sites/default/files/2009%20Ohio%20Infrastructure%20Report%20Card% B- structurally deficient bridges and two-thirds of the functionally obsolete bridges Dams Of 1,597 state-regulated dams in Ohio (out of 2,600 total) in 2007, 33% are deficient. Repair C cost is approximately $300 million. Drinking $9.68 billion in drinking water infrastructure needs Water D+ Electricity Mandates related to alternative energy and environmental protection may pose problems for C+ Ohio’s electric utilities in the future20Summary%20Update%20Feb%202010.pdf Roads Over 125,000 miles of roads with 43% in critical, poor, or fair condition. It is estimated that by D the year 2014, the state government alone will have a highway budget shortfall of $10+ billion. Transit An average of 500,000 riders use public transit daily (12th in the nation). Less than 1% of Ohio’s D state transportation funds go towards public transit. Wastewater C- $11.16 billion in wastewater infrastructure needsSource:

    • • National and International Rating Systems for Buildings – USGBC LEED® – NAHB National Green Building Program – Green Globes® – BREEAM (BRE Environmental Assessment Method)• National Sustainability Codes for Buildings – International Green Construction Code (IgCC) – ASHRAE 189.1
    • • National systems for roads, bridges, airports and infrastructure – None• Regional and state systems for roads, bridges, airports and infrastructure – Greenroads™ (Univ. of Washington) – GreenLITES (NYSDOT) – I-LAST™ (Illinois)
    • • The Role of the Civil Engineer in Sustainable Development – Promote broad understanding of economic, environmental, political, social, and technical issues and processes as related to sustainable developmentSource: http://www.asce.org/Content.aspx?id=8475 – Advance the skills, knowledge and information necessary for a sustainable future – Promote performance based standards and guidelines as bases for voluntary actions and for regulations in sustainable development for new and existing infrastructure
    • • Web-based certificate course that introduces participants to sustainability principles and to the established body of knowledge – Trends and Issues: economic, environmental and social concerns for sustainability – Social Factors: The Community and Individual Behavior – Sustainability Quadrant: human development and its ecological footprint – Moving Toward Sustainability: addressing sustainability in infrastructure sectors – Project Pathway and Performance: doing the right thing and doing the thing right• Culminates with an online and multiple choice exam• Serves as the first course in ASCE’s program of continuing education for Professional Certification in Sustainable Engineering (PCSE) – Available online in the 2nd quarter of 2011
    • • Envisioned to be an authoritative, nationally and internationally recognized professional certification• Will assure owners, public officials and the general public of the competence of professionals designing, constructing and managing infrastructure projects• The professional engineer (or other licensed infrastructure professional) will be PCSE certified• Scheduled for launch in the 1st quarter of 2012
    • • Formally launched in February 2011• Collaboration between ASCE, APWA & ACEC• Core Products and Programs – Rating System, including software application – Education and training – Professional (individual) certification – Project awards at various levels of performance
    • • Holistic, transformational approach – Performance-based (outcomes) rather than prescriptive – No other U.S. programs currently fulfilling need• Consider Triple Bottom Line• Similar to LEED but focused on civil infrastructure• Incorporate/reference existing rating systems, as appropriate – CEEQUAL (UK)• Scalable for size and complexity of projects• Adaptable for specific needs and circumstances – Provide for self-assessment, as well as independent verification• Voluntary
    • • Two-pronged purpose – Ensure that the project makes performance contribution • Contributes to sustainable performance improvement • Does things right, raises the bar – Ensure that the project makes a pathway contribution • Provides net contribution to affected community • Does the right thing, community-focused• Voluntary – Submit detailed design information – Evaluate against standardized criteria
    • • Project Management – Demonstrated Need For Project – Site Selection – Design Optimization – Best Practices to Deliver Social/Community Benefits• Efficiency of Land Use• Protection of Critical Lands (floodplains, prime farmland) – Contaminated lands – Floodways and Floodplains, wetlands
    • • Landscape – Comprehensive Plans – Land Use/Community Planning• Ecology/Environment – Conservation and protection of biodiversity – Habitat protection, restoration and creation – Monitoring and maintenance
    • • Waste Management – On site Waste Management and handling• Transport – Construction Transport • Nuisance, Disruption and Transport Mitigation • Workforce travel – Improved Traffic Flow
    • • Community Effects – Noise and Vibration – Air (dust and Odors) – Visual (views and light)• Engagement – Public interactions, awareness, involvement, influence, support• Employment – construction, operations, indirect, training, economic benefits

    • • Benefits – Gives access to references, project library, key resources and contacts – 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
    • • Benefits – 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
    • • Benefits – 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
    • • Benefits – 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

    • • The IgCC – Is enforceable language, in a regulatory framework forming an enforceable baseline of compliance – Uses the "model" code approach that provides communities the ability to modify w/ local amendments and built-in flexibility • Coordinated with the ICC Family of Codes – Is the “standard of care established by code”• How is it different from LEED? – IgCC forms the minimum requirements – LEED will continue to be the market transformation program to higher levels of sustainability
    • • Developed by – International Code Council (ICC) – AIA – ASTM – ASHRAE – USGBC – IES• Currently adopted by – Rhode Island (State agencies) – Richland, WA (voluntary to be enforced by code officials)• Oregon has passed a law requiring compliance above the IECC – The IgCC is considered compliant• Actively being considered in MD• ASHRAE 189.1 is an Alternative Compliance option
