Continue Water Efficiency
It must be noted that the remaining strategies are viable and are part of the CEAP, however
they either contributed below 75 tonnes or the carbon emissions reductions could not be
quantified due to lack of data. The reductions from the best management practices and
policies cannot be quantified since they are conceptual.
The consulting team then proposed a qualitative performance scale which was used to
assess the contribution of a strategy toward meeting the identified, weighted goals (the
decision criteria). For each decision criteria, several “levels” of performance are defined to
comprise the performance scale and a range of numeric performance measure benefit scores
is assigned to each level within the performance scale. For each decision criteria, the
associated performance measure benefit scale range is always a 10-point scale which allows
for a common measurement that provides a basis for comparing and making trade-offs
among competing objectives.

Scoring the Strategies
Workshop No. 2 was conducted as a facilitated scoring session for the identified top 32
strategies. Before starting the scoring, the Team Members verified that there were no
modifications needed to either the decision criteria or the performance scales to be applied
during the screening exercise. The Prioritization Team progressed through the scoring by
utilizing a personal handheld Audience Response System (ARS) device. Using their ARS,
each teammember entered their score, from 1 through 10 – using the qualitative
performance scales provided above – for each of the 4 decision criteria established in
Workshop No. 2, for each of the strategies. In addition, each team member completed a
scoring sheet on which they recorded their entered score and also wrote any comments.
During the scoring session, TeamMembers suggested the addition of the two following
strategies; the Team agreed to include the two strategies, bringing the total number of
strategies scored to 34:
CIP for Energy Efficiency City-wide
Hydroelectric Facility at Falls Lake
