Section 3.6 in 2013 TRM applies to air source air conditioner (Air Source AC), packaged terminal air conditioner (PTAC), ASHP and packaged terminal heat pump (PTHPs) measures and Section 3.18 applies to water source and geothermal heat pump measures. Table 3-20 includes the baselines for water-source and evaporatively-cooled AC, water-source heat pumps and ground source heat pumps, which do not apply to Section 3.6. Likewise, Table 3-65 includes the baselines for Air Source AC and packaged terminal systems, which does not apply to Section 3.18. To avoid confusion, the Commission proposes to update Tables 3-20 and 3-65 to only cover the measures that the protocols allow. In addition, the Commission proposes to add language in the 2014 TRM to clarify that Section 3.18 should be used to calculate savings for water-source and evaporatively-cooled AC measures. The Commission notes that these clarifications only remove extraneous information and do not affect savings values. Motor and Variable Frequency Drive Protocols Operating Hours, Energy Savings and Demand Savings The motor operating hours in Table 3-15 for the Motor measure and energy savings factor (ESF) and demand savings factor (DSF) values in Table 3-17 for the VFD measures in the 2013 TRM were adopted from the 2012 Connecticut TRM. As with the EFLH values for HVAC measures, the SWE ran computer simulation models to determine the motor operating hours, ESF and DSF values for motor and VFD protocols using eQUEST software for the 2014 TRM update. These computer simulation models are expected to provide state-specific values which are considered to be the most credible information after metered data. The SWE performed simulations for a set of prototypical small and large building types using eQUEST modeling. These prototypical simulation models were derived from the publically-available commercial building types created for the California DEER
