The use of zEPI as a common scale would help the California Public Utilities Commission (CPUC) and other regulators measure the overall impact of their building efficiency programs.
zEPI would enable all stakeholders in the building efficiency field to measure progress in the same terms and would remove the frustration of comparing percent savings past multiple moving targets.
The rating can be a normalized score (such as the zEPI scale) or a letter grade.
On the zEPI scale (in approximate terms) ASHRAE 90.1-1999 is about an 82; ASHRAE 90.1-2004, ASHRAE 90.1-2007, and California 2005 are about a 75; and California 2008 is about a 53 (see Figure 4; ASHRAE 1999, 2004, 2007a, CEC 2006, 2008a).
Comparing the ENERGY STAR percentile scoring curve for offices with the zEPI scale, the 50th percentile in Energy Star hits at about 94 on the zEPI scale (CEC 2009).
The recommended scale, zEPI, would be stable over time, with the 2003 CBECS normalized average most likely used to define the 100-point benchmark (EIA 2003).
zEPI pegs year 2000 average energy consumption at "100" and net zero energy at zero.
Energy codes can be pegged to zEPI, allowing progress toward goals of net zero energy to be evaluated.
Buildings in the design or construction process would use energy simulations to find their zEPI score, but modeling assumptions would need to be specified such that all energy use is included and such that modeling assumptions are set as close to reality as possible.
The remainder of this section probes the details and implications of shifting to the recommended stable scale, zEPI. The following topics or issues are addressed:
* How the code development update process might be shifted from the current bottom-up approach to a top-down approach that uses zEPI to set targets, which are later verified through the development of prescriptive packages tailored to building type and climate.
* How utility incentive programs and other incentive programs could be modified to use zEPI.
