What Does Sustainability Mean to People?
In a practical sense ‐ is it immediately clear to people how sustainability relates to their own work?

Bringing Sustainability Into Focus American Water – A Case Study
In late 2005, American Water embarked on an initiative to pursue LEED certification for four new water treatment facilities to be built in Illinois and Indiana.Structured framework and goals of LEED provided playing field for wrestling with concepts of sustainabilitySustainability into Focus
Connection of sustainability to their jobsExisting sustainable practices were “discovered”Search for new opportunities began

Initiating the InitiativeAmerican Water – A Case Study
Recognized that many existing practices already contributing to sustainability
Water loss reduction through leak detection and obsolete main replacementMeter replacementPreventative maintenanceFull‐cost water rates, re‐investment in infrastructure
LEED Certification appeared feasible without changes to budget or schedule of project

Good fit with American Water expertise and processes
Design‐Build project delivery model facilitates collaborative design and construction effort necessary for achieving goalLife cycle cost analysis standard approach for evaluating alternativesExpertise in full life cycle of facilities ‐ planning, engineering, construction, operation enables thorough evaluation of constructability, cost, and operability

LEED and the Water UtilityAmerican Water – A Case Study
Moving Forward with Appropriate Constraints
Maintain focus on function, cost‐effectiveness, value to rate paying customers.Decision making unchanged – alternatives appropriately subjected to life cycle cost analysisMinimize risk by targeting lowest certification level Budget & schedule trump certificationCommunicate externally after feasibility assured

ImplementationAmerican Water – A Case Study
LEED certification goal was identified in Requests for Qualifications and Proposals for design build servicesPlans for achieving LEED certification were integral to the proposals received from prospective design‐build teamsInternal presentations at management and functional group meetingsProject team orientation – intent, concepts, goals, constraintsProject delivery unchanged

Initial ChallengesAmerican Water – A Case Study
Skepticism of real value, viewed as an “extra” thing, a distractionCommon assumption that it would increase costs, could present risk to recovery of investment in ratesRequired stretching beyond familiar designsLEED‐NC was not designed for water treatment facilities, many measures are not practical
Challenges overcome when:It was clear that decision making would not be distorted by certification goalIt was appreciated that sustainability goals are well aligned with fundamental priorities and not a change of directionEnthusiasm of project team members made stretching beyond familiar approaches fun
