calculation of savings without requiring extensive measurement to evaluate saving; and To provide reasonable methods for measurement and verification of the incremental energy savings without unduly burdening program or evaluation staff. A summary of the adopted changes to the May 2009 TRM are as follows: Section numbers added for navigation and cross-referencing. Tables and text formatted consistently. Updated references. Footnotes added for references and notes. Modified “Commercial and Industrial Energy Efficient Construction” to “Commercial and Industrial Electric Efficiency.” Removed existing “Lighting Equipment” section. Removed existing “Prescriptive Lighting” section. Removed existing “Lighting Controls” section. Removed existing “20% Lighting Power Density (“LPD”) Reduction” section. existing “Fluorescent Lighting Fixture” section. “Lighting Improvement” section with “New Construction and Building Additions”, “Traffic Signal Lighting”, “Prescriptive Lighting”, and “Lighting Controls” subsections. existing “Motors” section. “Premium Efficiency Motors” section. “Variable Frequency Drive (“VFD”) Improvements” section. “Industrial Air Compressors with Variable Frequency Drives” section. EFLH table under the “HVAC Systems” section. “Electric Chillers” section.
For Custom Measure VFD applications, pre-approved software, with uniformly applied assumptions for all EDCs may be considered in conjunction with premeasurement or otherwise credible establishment of load shape. The software approval and the establishment of load shape would be defined in a pre-approved Custom Measure Protocol using procedures established in the Audit Plan as approved by the Director of CEEP. C. Commercial and Industrial HVAC Systems & Chiller Protocol The 2009 TRM provides protocols (algorithms and stipulated variables) for the measurement of savings for HVAC systems and chillers that are generally reasonable in theory but overly simplistic when considering the stipulated numbers. In Tables 19 and 21 of the 2009 TRM, EFLH values are fixed based on location, inferring that every HVAC and chiller system in a particular region operates at the same number of hours regardless of building type or function. This assumption is flawed, as one HVAC system could serve a school operating from 7AM to 5PM on weekdays only, while another HVAC system could serve a retail space operating from 9AM to 9PM every day in the same region. The same is true for chiller systems. Therefore, a more nuanced determination of the stipulated EFLH values is required to function properly in the established algorithms. The proposed new EFLH values for Commercial and Industrial HVAC systems and chiller systems are found in Section 6.6 and 6.7, respectively. Tables 19 and 20 of the proposed 2010 TRM issued with the Tentative Order on January 28, 2010 provide a large number of categories of Equivalent Full Load Hours (EFLHs) by building type from the US Department of Energy’s Energy Star Calculator and Bin Analysis Models. These categories represent the results of detailed research and provide reasonable estimates for the stipulated energy savings in these categories. Many of the categories provide similar values and represent similar functionality relative to
