System Power

 Fixture rated wattage from manufacturer spec sheets  Program administrator maintains a list of fixture wattages, based on:  Manufacturer spec sheets  DesignLights Consortium – solid state lighting  Energy Star  Efficient case wattage from manufacturer spec sheets  No provisional data collection required

Hours of Operation

 Information collected to estimate lighting operating hours by space use type  Control schedules  Occupancy schedules, interviews  Alternative approach – prescribed list of operating hours by building type and space occupancy type  Provisional data collection required (trend logging of lighting and current)

Controls

 Prescribed list of control savings by space & control type  Primary source – LBNL study  Secondary sources to fill study gaps  Programs with savings partially based on measured data  Provisional data collection required (trend logging of lighting and current)

HVAC Interactive Effects

 Prescribed list  Source – regional resource planning factors used for Sixth Power Plan  Based on DOE2 simulations of proto-type buildings by climate zone and fuel  No provisional data collection required

Provisional Data Collection

 Specific to operating hours and control impacts  Required until sufficient data collected to demonstrate reliability of savings estimates  Trend data collected  Lighting/current loggers  Sampling allowed within sites  Program sampling as per independent impact evaluation design

Protocol Calculator

 Demonstrates protocol calculation methodology  Fixture wattage inputs  LPA inputs for code-impacted measures  Operating hour input from provisional data (hours of use and/or controls) or default operating hours  Default list of control savings

July 3 Subcommittee Issues

 Define baselines clearly as per the Guidelines language of current practice and pre-conditions  Add custom measure language for defining baselines  Add lighting fixture data table to calculator (BPA list determined to be from mfg’s. data)  Provide RTF HVAC interaction by climate zone by building type and fuel
